CHAPTER 1 Installation Introduction Overview This chapter describes the front panel controls and the rear panel connectors in detail. It also describes how to use the front panel user interface for data display and system configuration. Configuration procedures are covered in detail in Chapter 3 on page 27.
C h a p t e r 1 In s t a l la t i on Sa f e t y Safety Important Safety Instructions IMPORTANT: 1. Read, keep, and follow all of these instructions; heed all warnings. 2. Do not use this equipment near water, rain or moisture. 3. Use only a dry cloth to clean the equipment. 4. Do not block any ventilation openings. Install only in accordance with the instructions in Installation Recommendations on page 4. 5.
C ha p t e r 1 Installation C o m p li a nc e • The equipment has been dropped. Safety Symbols WARNING: The symbol to the left is a warning to be careful of electric shock. Do not open the top cover with the power cord attached. Compliance FCC This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules.
C h a p t e r 1 In s t a l la t i on I ns t al la t i o n R ec o m m e n d a t i o ns contact Wohler customer support for assistance. (Wohler’s contact information is on page ii of this document.) In addition to the monitor, the package should contain: • A CDROM containing the product’s user guide, • A power cord, and • A warranty card Note: We recommend you retain the shipping carton for future use.
C ha p t e r 1 Installation I n s t a l la t io n R e c om m e n d a t io n s exceeded. Otherwise, allow a 1RU (1.75”/44.45mm) space above and below the unit for air circulation. Important: To reduce noise, the monitor does not have any fans. As a result, the heat generated by the class D power amplifiers, power supplies, and other components is vented by slots in the side of the unit. Therefore, as a safety precaution, you must allow proper ventilation on both sides of the unit.

If severe enough, such reflections can result in corruption of the digital data stream.
C ha p t e r 1 Installation I n s t a ll a t io n Power Up The AMPx-E8 Series monitors are factory-configured so that all settings are non-volatile. When power to the unit is cycled (off/on), the unit will restore itself so that each setting such as channel selection(s), input type, and so on, are automatically restored to the unit’s previous factory setting. However, you can custom configure the monitor to automatically restore your configuration settings on power up.

CHAPTER 3 Audio Configuration Introduction Overview This chapter is the “how to” chapter. All topics listed below are sorted alphabetically for easy reference. For information about presets refer to Chapter 4: Presets on page 43. For information about using the Dolby features, refer to Chapter 5: Dolby on page 49.

Press either the Up or Down arrow followed by the Enter button to change the setting, or press the Escape button to leave it as is. 5. Press the Escape button again to return to normal operation. Monitoring and Mixing Modes Arbitrary Mixing 1. Press any of the eight speaker assign buttons to activate the mixing (summing) feature.
C h a p t e r 3 A u d i o C o n fi g u r a t io n M o n it or i ng a n d M i x in g M o d e s Single This mode allows you to select one and only one signal for each speaker independently of the other speaker and is most useful when you are monitoring mono sources. To select channels individually for each speaker: 1. Press the Fn + Single buttons to enable single channel selection. Figure 3–5 Single Channel Selection CH1 2.
C h a p t e r 3 Audio Configuration M o n it o r in g a n d M i x in g M o d e s Downmix This mode is most useful when multiple signals need to be mixed together and monitored at the same time. DM1-3 are designed for 5.1 surround sound signals, and assume a channel arrangement of (Channels 1-6 respectively): • Left Front, Right Front, • Center, LFE (Subwoofer), • Left Surround, Right Surround. 4+4 Mode, Mix A, and Mix B are provided for other types of multichannel monitoring needs. 1.

Contribution of the surround speaker Assign is set by the surround level entry in the Setup Menu. DM2 is equivalent to the Japanese ARIB Set 2 downmix formula. See Figure 3–8 below.
C h a p t e r 3 Audio Configuration M u t i ng t h e S p e a k e r s • DM3: This downmix is the same as DM1 except that the surround level is fixed at –3 dB. DM3 is equivalent to the Japanese ARIB Set 3 downmix formula. See Figure 3–9 below. Figure 3–9 DM3 Mix Diagram • 4+4: In this downmix Channels 1 through 4 are summed to the left speaker and Channels 5 through 8 are summed to the right speaker.
C h a p t e r 3 A u d i o C o n fi g u r a t io n Ph a s e C or r e la t io n Pressing the Mute button allows you to step through three mute states and an unmuted state. When the system is in one of the mute states, all other information normally shown in the LCD such as the Input Status Display is disabled. In addition, all other buttons are displayed until you unmute the system. See Table 3–2 below.
C h a p t e r 3 Audio Configuration SDI Inputs • Right (+): Selected channels are in-phase (+1 correlation maximum). With typical stereo program material, the moving block display is normal. If the signals to the speakers are completely independent, they will have a correlation result of 0, and the block will be stationary in the center of the screen. See Figure 3–10 below for an example.

Press the Group button quickly to select the group and then wait until the display flashes once. 2.
C h a p t e r 3 Audio Configuration SDI Inputs Example: G11/2 will appear on the bottom left hand side of the LCD screen when the user wants to monitor a bitstream in the first sub-group of Group 1. This corresponds to Channels 1 and 2 of an ordinary PCM embedded audio signal. Similarly, G33/4 will appear when the user wants to monitor a bitstream in the second sub-group of Group 3.

A given input should be terminated when the AMPx-E8 is the last receiving device in the signal path or is the only receiving device in the signal path.
C h a p t e r 3 Audio Configuration Te r m i na t i n g / U n t e rm in a t i ng I n p u t s Important: 4. Press the Up or the Down buttons until the desired input is shown on the screen. 5. Press the Enter key to change the termination setting for that input. Repeat Steps 4 and 5 until all the inputs have been set according to your needs. 6. To exit the menu, press the Up or Down arrow buttons until Save and Exit appears in the LCD, as shown in Figure 3–17 below.
CHAPTER 4 Presets Introduction Overview This chapter describes how to create, recall, modify, and erase presets. It also discusses using Preset mode for fast system configuration.

C h a p t e r 4 Pr e s e t s W h a t a r e P r e s et s? What are Presets? The AMP1-E8 is an incredibly flexible tool for monitoring multiple audio streams. You can configure the entire system to function exactly the way you want it to for your specific application. You can store a complete system configuration into a preset. After saving one or more presets, you can quickly scroll through them with the press of a single button. The AMPx-E8 allows you to store up to 10 presets (numbered 0 through 9).
C h a p t er 4 Presets M e t h o d s o f A cc e s s in g t h e Pr e s e t s Note: When this mode is enabled, you can no longer directly select the inputs by the input type (e.g., AES 1, SDI 2, analog, and so on). The inputs are accessed only indirectly through the presets in this mode. To access the inputs by input type, you must first disable Preset mode. Enabling/Disabling Preset Mode To enable or disable Preset mode: 1. Press Fn+Setup. 2.
C h a p t e r 4 Pr e s e t s M e t h o d s of A c ce s s in g t h e P re s e t s Saving a Preset 1. Press Fn+Preset 1. If Preset 1 is currently empty, the system will prompt you to save the current unit configuration to Preset 1. 2. Name the preset by using the Up and Down arrow buttons to scroll through the available list of characters. Press Enter to accept each character. 3. When you’re done entering all the characters, scroll until _DONE_ appears in the window, and press Enter.
C h a p t er 4 Presets M e t h o d s o f A cc e s s in g t h e Pr e s e t s 5. Name the preset by using the Up and Down arrow buttons to scroll through the available list of characters. Press Enter to accept the character; repeat the process until all the characters have been entered. 6. When all the characters have been entered, scroll until _DONE_ appears in the window, and press Enter. Note: _DONE_ is located between the lowercase letters and before the numbers.
