Maximizing the Value of Your Purchase Congratulations on choosing a superb product. Your Proceed Audio Video Preamplifier (AVP) is designed to give you many years of outstanding performance, and we are confident you will be happy with it. We value our relationship with our customers, and often are in a position to help you enjoy your home entertainment system even more—if we have some way of contacting you.
Unpacking and Placement unpacking the audio video preamplifier Unpack your Audio Video Preamplifier and remove all accessories from the carton. Important! Keep all packing materials for future transport of your Audio Video Preamplifier. Shipping your new component in anything other than its purpose-designed packing material may result in damage that is not covered by the warranty.
Drawings are included in this manual to facilitate special installations and custom cabinetry (see Dimensions). An optional, purpose-designed rack mount kit is available for this product, drawings of which are also included at the end of this manual (see Rack Mount Kit). The serial number for your Audio Video Preamplifier is found on the bottom of the unit. Please note and record this number for your future reference.
Operating Voltage & Frequency The Audio Video Preamplifier is set at the factory (internally) for 100V, 120V, 220V, 230V, or 240V and either 50 or 60 Hz AC mains operation, as appropriate for the country in which it is to be sold. (230V/50Hz only in European Union countries, in compliance with CE regulations.) Neither the voltage nor the line frequency setting may be changed by the user.
A Word About Installation Every effort has been made to make the Proceed AVP simple and straightforward to install and use. We know of no other product which offers this level of performance and flexibility (other than the more costly Proceed PDSD system). Still, we have no way to evaluate many other variables such as the size and shape of your room, its acoustics, and the associated equipment you have chosen to use with your AVP. All of these factors influence the ultimate performance of your system.
The Quickest Start: CD & DVD The AVP is an exciting system, and we understand that many owners will be anxious to get it up and running as quickly as possible. What follows is not a replacement for a complete setup of the system. Rather, it is provided so you can get some music and movies playing as quickly as possible. It assumes that your system is already set up in other respects (speakers connected to power amps, etc.).
A Quick Start For CD There is a reasonable chance that either your CD transport or your DVD player may have a different set of output connectors than what we have assumed it might have in the “quickest start” section. In that case, setting up the AVP to take advantage of your particular equipment is still quite simple, though it will require a couple extra steps.
A Quick Start For DVD We understand: you’re in a rush to hear Dolby Digital on your new system. Remember: What follows is not a replacement for a complete setup of the system. We will assume here that you have already done the CD setup on the previous page. To get a DVD player playing: 1 MAKE THE PHYSICAL CONNECTIONS Noting which connectors you use, connect a digital output of your DVD to any matching digital input on the AVP, and a video output of your DVD to a corresponding video input on the AVP.
Special Design Features Congratulations on your purchase of the Proceed Audio Video Preamplifier (AVP). We have gone to great lengths to ensure that the AVP remains “future-proof” even in these times of change. As a result, you will be able to enjoy the outstanding performance of the Audio Video Preamplifier for many years. In case you are interested in technical details, what follows is a brief outline of some of the key technologies in your new product.
multichannel audio computer The Audio Video Preamplifier is designed to be flexible with respect to its audio configurations, as well. In its standard configuration, it provides the standard 5.1 channel selection of outputs made popular by home theater. However, it also includes an extra two channels that may be used in any of several ways, whether to accommodate larger rooms (separate side and rear speakers) or more sophisticated audio processing (Dual Drive™ surrounds, for example).

3 AUDIO SOURCES These four buttons select audio signals from among the defined audio-only inputs. (See define source buttons in The Setup Menu section of this manual.) To use these selection buttons, choose the appropriate path (see path, below), and then make your selection. Selecting any audio source after having selected a video source will cause the newly-selected audio signal to “override” the audio portion of the video selection (leaving the video signal unaffected).
Tip: To avoid any possibility of running into a “Tape Loop” problem (where the AVP prevents you from choosing what you want, in order to protect the system from possible damage), simply select a non-recording source on the record path.
8 RECALL Pressing the recall button restores the AVP to its calibrated reference settings for the relative output of all speakers.
You can also create a different, default input level setting for each analog source defined in the menu system. If you can generate a 1 kHz, 0 dB reference signal in the source component (for example, a cassette tape recording of a 1 kHz test tone, with the recording meters showing 0 dB), use this signal to calibrate the input. With the volume of the AVP turned down, play the 0 dB test tone, and adjust the input level until the indicator light first turns on.
Turning the knob clockwise in the balance mode will shift the image to the right; turning the knob counterclockwise will shift the image to the left. 22 16 CENTER Pressing this button followed by adjusting the volume knob (or volume ± on the remote control) will alter the volume of the Center speaker relative to its normal, calibrated setting. The resulting offset will be indicated in the main display, as well as by the on screen display, until the volume control reverts to its normal, master mode.

Refer to the operating manuals of your balanced-output line-level sources to verify that the pin assignments of their output connectors correspond to the AVP.
operating manuals of your digital sources to verify that the pin assignments of their output connectors correspond to the Audio Video Preamplifier. If not, wire the cables so that the appropriate output pin connects to the equivalent input pin.
Connect the video outputs of your video components to appropriate video inputs on the AVP. (See The Setup Menu for more information on programming your input buttons for either composite or S-video use.) Installation Note: S-video (Y/C) signals are more susceptible to degradation over long wire runs. The quality of wire used makes a significant difference, but regardless, it is generally inadvisable to run S-video cables more than twenty feet (6 meters).
In addition, two “auxiliary” output channels are provided, labelled aux 1 and aux 2. These channels are reserved for future use, for applications such as separate side and rear channels, or to provide left-center and right-center outputs for the MPEG 7.1 format used in Europe, or as additional subwoofer channels (front and rear, left and right, or common-mode).
Thus you can watch one program while recording another; or watch one program while sending a different one to another part of the house; or you can watch what is being recorded from either another part of the house or from within the main room. But there is a limit: you cannot have three independent programs running simultaneously on the main, remote and record paths, because the remote and record paths always share a single source.
The RJ-45 cable needed for the connection between the AVP and other PHAST-compatible Proceed components may be purchased from your Proceed dealer. It may also be easily and inexpensively made to length using two RJ-45 connectors and the appropriate length (up to 100 feet/30 meters) of RJ-45 (flat, eight conductor) cable. RJ-45 cables and connectors are used throughout the world for both telecommunications and computers, and are widely available at low cost.
Note that only qualified technicians should attempt to make use of the special capabilities afforded by this communications port. 15 IR INPUT A 1⁄8" “mini” jack labeled ir input near the lower right corner of the rear panel provides direct access to the infrared control circuitry of the AVP.
17 VIDEO OUTPUTS Two different video configurations exist for the AVP: composite video only and both S-video and composite video. The composite-only version includes four composite outputs, while the Svideo version includes four composite and two S-video output for a total of six. Any combination of the available output may be used, and for your convenience, conversion from S-video to composite is provided on both the main and the record/remote paths.
The Proceed AVP has been safety-tested and is designed for operation with a three-conductor power cord. Do not defeat the “third pin” or earth ground of the AC power cord.
The Remote Control The AVP itself is capable of teaching sophisticated learning remote controls a wide range of highly specialized functions, if you feel you need such capabilities.
video: cycles among the defined audio/video sources from the first to the last, returning to the first. If you have A/V buttons that are defined as “unused” in their Define Button menus, they will be omitted from the list of A/V sources this button accesses. Since this button acts as a rocker switch, you can move either forward or backward within the list of defined A/V sources. audio: cycles among the defined audio-only sources from the first to the last, re- turning to the first.
Using The Menu System The AVP uses a dynamically-updated menu system that operates more intelligently than most such systems. For example, when configuring inputs, the menu options change according to the selections you have made. In effect, the AVP only asks you for relevant information, thereby minimizing possible confusion. Four buttons on the remote control are used to navigate through its extensive on screen menu system: menu, enter, volume +, volume –.
should you ever need to call for technical support. You might want to copy these (somewhat arcane) numbers down in the Your Settings section of this manual for future reference. to exit the menu system From the AVP Main Menu, pressing menu again will exit the menu system. Since pressing menu (once within the menu system) also cancels current actions and moves you up one level in the menu hierarchy, you can leave the menu system by pressing menu repeatedly—no matter where you are within the system.
Once in the menu system, the front panel equivalents are: • menu • enter • volume ± = recall = mute = volume knob (to cancel an action, or move up a level) (to save a change and/or move up a level) (to move up or down in a menu, or increase/decrease a value) As with the menu button on the remote control, clicking recall on the front panel when the main menu is displayed will exit the menu system.

(This example assumes you have the optional RF demodulator, of course.) migrating to analog If the automatic migration feature moves to an analog connection, it will stay there until you either force a manual migration (see below) or select a different input. This is due to the fact that the hardware that would normally be detecting a restored digital signal is already fully occupied receiving your analog signal after it has been converted to digital.

• relative—on a scale which is measured “plus or minus,” relative to the calibrated reference volume (established during calibration). As an example, if your calibrated reference level is 70, the display would read 0 in the relative mode when it would read 70 in the absolute mode. Most people find absolute more intuitive, while some people find relative more informative.
others in the home are sleeping, or in an apartment building when neighbors are at home and prefer not to be disturbed. Simply turning the volume down may not be an adequate solution in these cases, as it may make dialog so quiet as to be unintelligible, and obscure important but subtle cues in the soundtrack.

To take a common but surprisingly complex example, imagine: • that you have a laserdisc player that has an RF Dolby Digital (AC-3) output, a digital output, and analog outputs; • that you usually listen to it in THX cinema mode, whether using discrete digital soundtracks or Dolby Pro Logic soundtracks; • and that you prefer to use a subwoofer for movies for the extra impact, but prefer not to use it when listening to music.
renaming source buttons defining the input type Your first decision: would you like the on screen display to identify your CD transport with something more specific than a generic cd name? If so, enter the characters one at a time, up to a maximum length of eight. 1 MOVE THE SELECT-IT CURSOR BESIDE “NAME:” AND PRESS ENTER TO ALLOW FOR CHANGES TO BE MADE. A blinking box indicates the first available space for your new name.
Note: These “surround modes” refer to what the system does when given a generic, two-channel input signal, whether analog or digital. Dolby Surround encoded signals are such a two-channel signal as they enter the Audio Video Preamplifier, one that has been encoded to provide multiple channels when properly decoded. Discrete multichannel signals (such as those provided by Dolby Digital, DTS, or MPEG) will override these surround preferences and always be reproduced in their intended multichannel forms.
1 MOVE TO THE “REC OUT:” ITEM IN THE MENU, PRESS THE ENTER BUTTON, AND USE THE VOLUME ± BUTTONS TO INFORM THE SYSTEM WHETHER A RECORD OUTPUT IS BEING USED WITH THIS SOURCE COMPONENT; PRESS ENTER AGAIN TO SAVE THE CHANGE Your choices are no, warn, and prohibit. For a CD transport, you’ll probably leave it at no. If you were setting up a cassette deck, you should choose prohibit, which would ensure that you do not accidently send a source back to itself to be recorded.
CD-AUDIO INPUT 1 AUDIO: DIGITAL CONN: DIGITAL 1 example: setting up a laserdisc player 2 PRESS ENTER AGAIN TO WORK WITH “AUDIO:” AND CYCLE THROUGH YOUR OPTIONS WITH THE VOLUME BUTTONS; CHOOSE DIGITAL AND PRESS ENTER TO SAVE Once again, this is the factory default setting. Were you setting up a CD player that had only analog outputs, though, you would want to change this to analog and use a set of analog connectors on the AVP instead.
Note: In this and other menus, connectors that are already associated with another, different button are displayed in yellow letters instead of white. This is done to keep you informed as to what inputs might be available. Now the system knows which video connector to look at when you want to watch a laserdisc. Next, let’s move to the audio connectors. (You can change the surround mode default along the way if you like… but you already know how to do that.

If you chose to set up two connections (lacking an RF output), then your second connection will be your analog hookup. Choose audio: analog in the submenu, and then choose the analog input where you hooked up the analog connections from your laserdisc player).

As you can see in the screen shot above, the main speakers may be defined as full range, meaning that they can reproduce any deep bass that might be sent to them to your satisfaction. By selecting x-over rather than full rng, the selected speakers will receive only frequencies above the crossover frequency, with frequencies below the crossover frequency being divided among subwoofer(s) and any speakers listed as “full range.
If you do not have THX speakers, define which (if any) of your speakers is full range, and select an appropriate crossover frequency below which bass is redirected to bass-capable speakers. important note about your subwoofer: set distance 1 ENTER THE SET CONFIGURATION MENU AND DEFINE HOW YOU WANT YOUR FRONT L&R SPEAKERS TREATED Using enter and the volume ± buttons, choose either full rng or x-over (the crossover) as appropriate for your front left and right speakers.

By now you should be quite comfortable navigating the AVP menus, so we will simplify the “how-to” explanations. If you are coming directly to this portion of the manual without having read the previous sections, please review those sections before proceeding. They contain important information you need to know about, in addition to detailing the menu navigation system. Try starting at Using the Menu System.
output level controls. An appropriate SPL meter can be purchased from Radio Shack for about $30 U.S. (tip: buy the analog meter rather than the digital one). You should point the meter at the ceiling so as to avoid inadvertently favoring one speaker over another. In the absence of an SPL meter, it is possible (though less desirable) to set the output level controls by ear. Use the built-in pink noise generator in the AVP to adjust all volumes to sound the same as they cycle around the various speakers.
5 bass level manager SAVE ALL YOUR CHANGES AND RETURN TO THE SETUP MENU Once you have each channel adjusted properly, press menu to return to the set speakers menu so you can continue the initial setup of your system. Some powered subwoofers have built-in protection against overload, or have amplifiers designed to be incapable of destroying the subwoofer driver itself.
When you choose to use the test signal by changing test signal: from off to on, the low frequency test signal will be sent to your subwoofer(s) at a modest volume. Regardless of the previous setting, the initial setting of the bass level manager when you enter its menu is a low value of 30. This is done to avoid a sudden, potentially speaker-endangering level of the test signal being sent to your subwoofer(s).
control. You may also return to the calibrated (no offsets) setting by pressing recall. You may also elect to force the subwoofer either on or off (you may, of course, leave it in its default condition, as defined by the set configuration menu). This effectively allows you to change the speaker configuration for each surround mode, at least as far as bass management is concerned.
This extra step ensures that any automated changes of output levels are consciously chosen and therefore less likely to cause surprises. It also allows you to disable all the surround mode defaults in one easy step, should you decide at some future date to return to the calibrated settings for all your routine listening. 2 SELECT THE SURROUND MODE YOU WOULD LIKE TO MODIFY For example, when you have selected the discrete mode (e.g.

This will cause even offsets entered at the front panel to be reset to all zeros when surround modes other than the one you changed are selected.

In it, we will cover: • teaching new IR commands from the AVP to a learning remote control • programming the two DC “trigger” outputs on the Audio Video Preamplifier • the use of the rear panel IR input • the use of the rear panel RS-232 port • integrating the AVP into a PHAST home automation system In short, you have to be a bit of a gearhead to enjoy this section.

The About… Menu ABOUT...

You might consider copying these numbers down for future reference in the back of this manual under Your System Settings. That way, you will be able to take the numbers to the phone with you if you have to call.
Using the Special Menu The AVP remote control includes a button labelled special which can serve a variety of functions, depending on your personal preferences. To access the full list of features controlled by this single button, press and hold the special button on the remote control for several seconds, until the special key actions menu appears on screen. special key actions menu SPECIAL KEY ACTIONS STATUS DISPLAY THX TOGGLE CENTER LEVEL REAR LEVEL SUB LEVEL SUB TOGGLE BALANCE OFF O.O O.O O.

Using the AVP setting the volume Normally, when you wish to change the volume, you want all the speakers to move up or down together, maintaining their relative balance. Thus the volume control (either front panel knob or remote control button) will operate as a master volume by default. Occasionally, you may want to change the volume of some speakers relative to others; for example, you may want to increase the level of the rear speakers a bit for more dramatic surround effects.
When in doubt as to whether THX cinema processing should be included, listen for a natural presentation of the treble. Films mixed for theatrical release exhibit an elevated treble region when played back on a home system with flat response. The THX cinema mode will correct this. Conversely, surround-encoded programs without this high frequency emphasis might sound dull or lacking in detail when (incorrectly) played in the THX cinema mode.
automatic migration If you have multiple connections defined for a particular source, the AVP will automatically use the highest-priority connection available. For example, if you have chosen AC-3 RF demodulator, followed by digital, followed by analog for your laserdisc player, the system will first look to the RF input. If it cannot lock onto a signal there, it will move to the digital input. Lacking a signal there, it will migrate to the analog input.
Planning Your Installation The information contained within this section is intended to help get someone started who wishes to design and install their own sophisticated A/V system built around the Proceed AVP combination. However, it cannot be considered a substitute for the experience, expertise and specialized training of an audio/video installation professional. (See A Word About Installation, page 12.
locating the components well away from the field of vision can be effective (if mechanical noise from transports, etc. is not a problem). Attention should be paid to the accessibility of the infrared control signal to the components. Most people instinctively aim remote controls at the screen, without thinking about the location of the equipment.
toe-in of left & right speakers L sur sub L C R sur R Some toe-in of the Left and Right speakers toward the main listening area (see above) will help minimize side wall reflections and balance the sound for people at the extreme edges of the viewing area. If possible, it is usually desirable to have the side walls between the front speakers and the listener be acoustically absorptive to further minimize early side wall reflections.
dipolar surround placement L sur sub L C R R sur If more traditional speakers are used, you may want to consider placing them such that their output is scattered across the rear of the room. (See diagram.) This placement provides a diffuse soundfield somewhat similar to the dipolar speakers.
Room Acoustics The following information on room acoustics does not need to be considered in every installation. Rather, it is provided for those who plan a dedicated listening room, or for those who feel they have a problematic room and therefore need ideas about how to improve their system’s performance further. Once again, the value of your dealer’s experience should never be underestimated.
built. A light, flexible wall may “leak” bass into the next room, reducing the magnitude of the effect.) The Boundary Effect is particularly important when it comes time to position the front speakers. If they are not placed consistently with regard to adjacent room boundaries, the tonal balance or timbre of sounds panned across the front may change, weakening the illusion of a real object moving across the soundstage.
System Planning Guide Experience shows that almost any reasonable amount of time spent in the planning stages will pay for itself two to three times over during the installation— more if the installation crew includes two or three people. With the background provided in the previous sections, the planning process can be boiled down to a checklist which will ensure that you do not overlook anything important. video placement ■ The primary seating area should be perpendicular to the picture.

If THX-certified LCR speakers are used and must be either above or below ear level when seated, aim them down (or up) into the listening area. They are intentionally quite directional in the vertical plane, to improve dialog intelligibility and localization. Placing the LCRs below the screen is generally preferable to placement above.
Your System Settings The settings in your Proceed AVP are saved in nonvolatile memory and should normally survive power outages. Still, it is a good idea to write your preferred settings down against the chance of an inquisitive neighbor or family member changing them without your knowledge.

Troubleshooting Your Proceed Audio Video Preamplifier has been designed to deliver many years of satisfaction. It has also been designed to allow an unusual amount of “customization” so as to make it suitable in a wide variety of (possibly changing) circumstances. This flexibility necessitates a certain amount of setup before the unit can be expected to perform correctly—in effect, one must inform the system of its environment so it may make the right “decisions” about what it should do.
I LEFT THE SYSTEM ON, BUT JUST RETURNED AND FOUND IT IN STANDBY. WHAT IS HAPPENING? ✓ There was probably a power outage while you were away from the system. During a power failure, the AVP saves all of its critical settings to nonvolatile memory. When power is restored, it enters the standby mode and waits for your return. MY ON SCREEN DISPLAY JUST INDICATED THAT THE AVP WAS GETTING TOO HOT. WHAT DO I DO NOW? ✓ The simplest thing to do is to increase the ventilation being provided to the AVP.
Care and Maintenance To remove dust from the cabinet of the Audio Video Preamplifier, use a feather duster. To remove dirt and fingerprints, we recommend isopropyl alcohol and a soft cloth. Caution! Always apply the isopropyl alcohol to the soft cloth and then wipe the Audio Video Preamplifier with the dampened cloth. Never pour or spray even small amounts of any liquid directly on the Audio Video Preamplifier, as doing so may allow the liquid to reach the circuitry inside the unit.
