3 mono input 1 HPW owner’s manual TM +48V - +48 volts DC is applied equally (through current-limiting resistors) to both pins 2 and 3 on the mic-input XLR connector. This feature is used with condenser microphones and active direct boxes that require an external DC voltage (phantom power) in order to operate. For dynamic or ribbon mics, phantom voltage is not required and should be switched OFF.
EQ features mono input 3 Many audio signals coming into the console require some degree of corrective equalization in order to be part of a good sounding mix. The input EQ consists of four-bands: high, high-mid, low-mid and low. The high and low bands have fixed frequencies, while the high-mid and low-mid bands are sweepable, with their higher and lower frequencies overlapping adjacent bands.
3 mono input 11 HPW owner’s manual TM PRE (aux 1–6) - The default signal source for these Aux sends is post-fader. This switch is used for selecting the Pre-fader signal for Auxes 1-6. The normal Prefader signal is derived Post-EQ. (See internal jumper options on page 18.) Aux sends are Post-EQ, Post-fader 11 Aux sends are Post-insert, Post-EQ, Pre-fader 12 aux send level 1–10 These knobs adjust the amount of signal sent to the corresponding AUX buses.
mono input 3 channel muting features The HPW™ is equipped with an 8-Scene muting system. An input channel can be assigned to any of the 8 available groups (1 thru 8). When a Mute Scene preset (located in the Master module) is active, all channels assigned to that scene are muted. In addition, the local channel mute switch can be used to change the status of the channel independently of any of the scenes.

mono input - options 3 user options There are a number of user options available for the Mono inputs. These are implemented by way of solder-pads on the back-side of the Mono Input circuit boards (upper EQ board of the pair). There are a number of solder-pads available, made up of split-circles of tinned copper. Solder is bridged (blobbed) across the 2 halves to complete the circuit and implement the desired option.
4 features overview HPW owner’s manual TM rear panel features 19 direct out 1/4" TRS jack - The input channel's signal is available at this output jack. The default signal routing is derived Pre-fader/Post-EQ. This can be changed by an internal option to Post-insert/Pre-EQ. The output jack is TRS, impedance-balanced. 20 insert jack - This switching 1/4” TRS jack allows an external signal processor to be inserted into the signal path of the channel.
automix automix (optional) 5 The automix option is comprised of a set of eight mono channels that have automatic gain-shared mixing capability. The circuitry determines which input is the loudest and gives it dominance in the mix by reducing the level of other assigned inputs, based on their individual instantaneous levels. Adding priority will cause a channel to dominate, even if its level is lower than others.
stereo input - options 5 23 gain 1&2 - These controls adjust the input gains of the two selectable inputs (TRS 24 left, right and mono switchs - These buttons determine which signal(s) will and RCA). Both Left and Right circuits are simultaneously adjusted. Unity gain is at the mid-point (with a detent), min and max gain adjust is 20dB. The stereo inputs were designed for line-level sources and can accommodate a wide range of input levels. Use the appropriate input when patching-in your external gear.
5 stereo inputs HPW owner’s manual aux send features Ten aux sends are available for creating individual output mixes from the Stereo Inputs. These mixes can be used for driving effects processors, providing monitor mixes, creating broadcast or alternate sound reinforcement mixes, or other special requirements. When in the default post fader configuration, the signal is an equal sum of the Left and Right stereo signals.
channel muting features stereo inputs 5 31 mute - Pressing this switch mutes the stereo feed to any of the assigned buses and any Aux sends. The mute is part of the mute scene programmable function and behaves just as the mutes in the mono channels do. 32 mute LED - The associated red-LED illuminates when the stereo channel is muted. 31 32 bus assignment features The bus assignment section offers considerable flexibility in creating what eventually becomes the main output mix.

6 groups (audio subgroups) HPW owner’s manual TM features The HPW is equipped with 8 audio subgroups, in addition to the main L/R and Mono mix buses. All of the Inputs (Mono and Stereo) have full assignment capabilities to all 11 of these mix buses. Typically, these 8 groups are used to create sub-mixes within the main program. These sub-mixes are then combined to create the overall mix.The use of groups allows the operator to easily control and modify collections of instruments or voices.
groups 6 group monitoring features Within this Group section, the 100mm fader is normally in the Group audio path. This can be changed with the use of the Fader-Reverse switch. When the Fader-Reverse switch is depressed, the corresponding Aux output is controlled by the 100mm fader (the Group output is then controlled by the corresponding Aux rotary pot). Since the actual signal at the fader can be either the Group or Aux mix, the PK/Sig LED and AFL switches will monitor whichever signal is at the fader.
6 groups HPW owner’s manual TM fader-reverse function using the HPW as a monitor console Because of its 10 Aux sends, the HPW can be used as a 10-output Monitor mixer. Each input channel can access all of the individual Aux mixes, allowing 10 unique mixes to be generated. Normally, the output level of each of these Aux mixes is controlled by the corresponding Aux Master rotary level pot.
group mixing features After using the groups to create the desired sub-mixes, you typically want to route and combine them with other signals or groups to create various output mixes.These mixes can be your final house mix (L/R/Mono), a special mix for a choir or vestibule area, or an additional feed tailored specifically for a video or TV broadcast.
6 groups HPW owner’s manual TM group connectors- rear panel The HPW group output connections are located on the Master rear output panel. Each group features a 1/4” TRS output connector, along with a 1/4” TRS Insert connector. The output is a ground-compensated, impedance-balanced TRS jack. For wiring purposes, treat this connector exactly like a balanced output.
auxes 7 auxes (auxiliary mixes) Ten Aux buses are available for creating individual output mixes from the Input channels of the Console. These mixes can be used for driving effects processors, providing monitor mixes, creating broadcast or alternate sound reinforcement mixes, or other special requirements. The Aux buses are fed from the Aux Send controls on the Mono Inputs, Stereo Inputs, Stereo Returns and the Ambience Input.
7 auxes HPW owner’s manual TM aux connectors-rear panel The HPW Aux output connections are located on the Master rear output panel. All of the auxiliary outputs are fully balanced with auxes 1-8 featuring XLR connectors and auxes 9 and 10 having 1/4” TRS connectors. All 10 auxes also have TRS inserts. The TRS Insert jack is wired as Tip=Send, Ring=Return, Sleeve= Audio Ground.This is the “industry-standard” wiring scheme for most single-jack inserts.
left - right 8 left and right (main audio buses) features The HPW is equipped with 3 main audio buses in addition to the 8 audio subgroups. 54 This section of the manual deals with 2 of those 3 main buses - Left and Right, and the Mono bus will be described later. The assignment to the L-R buses is always through a pan-pot, either from the Mono or Stereo input channels, or from the 8 55 audio subgroups.Typically, these 2 main buses are used to create the overall stereo mix.

Each input channel can access all of the individual Aux mixes, allowing 10 unique mixes to be generated. Normally, the output level of each of these Aux mixes is controlled by the corresponding Aux Master rotary level pot.
mono (main audio bus) mono output 9 features 62 The HPW is equipped with 3 main audio buses in addition to the 8 audio subgroups. This section of the manual deals with 1 of those 3 main buses - the Mono bus.The Mono bus is directly assignable from all of the Mono and Stereo Inputs, the 8 audio subgroups and the L-R main buses.
9 left - right, mono output HPW owner’s manual L/R and mono connectors- rear panel The HPW Mono output connections are located on the Master rear output panel. The output features a male XLR output connector, along with a 1/4” TRS Insert connector. The output is a servo balanced XLR jack. The TRS Insert jack is wired as Tip=Send, Ring=Return, Sleeve= Audio Ground.This is the “industry-standard” wiring scheme for most single-jack inserts.The Insert sendpoint is located directly after the main mix amp.
matrix mix 0 matrix mix The HPW features a 2-output Matrix section. Each Matrix can consist of a mixture of any of the 11 main mix buses: the 8 audio subgroups, Left, Right, and Mono. Each of these main buses feed the 2 matrix buses through individual Matrix Send pots, all located within the Master module, above the fader of the associated bus.These Sends were described in each of the previous sections describing the various buses.
¡ master section HPW owner’s manual TM stereo returns features The HPW has 2 stereo returns located within the Master module. These inputs are designed to accept line level balanced signals (from an effects unit, a CD player, or other line level source) on their 1/4” TRS balanced jacks. 69 69 gain 70 This control adjusts the gain of the input amplifiers. Both Left and Right circuits are simultaneously adjusted. Unity gain is at the mid-point (with a detent), min and max gain adjust is 20dB.
master section ¡ EQ features Many audio signals coming into the console require some degree of corrective equalization in order to be part of a good sounding mix. Each stereo input is equipped with a fixed-frequency, three-band EQ. The HF and LF bands have a shelving response. The MF band is bell-shaped, centered at 3kHz. The EQ circuitry is always in the signal path. Set all EQ controls to “0” (flat) if no equalization is desired.
¡ master section HPW owner’s manual TM channel muting features 75 MUTE and MUTE LED Pressing this switch will mute the stereo feed to any of the assigned buses and any Aux sends.The associated red-LED will illuminate when the stereo channel is muted. bus assignment features The bus assignment section offers considerable flexibility for creating what eventually becomes the main output mix.
signal monitoring features master section ¡ The stereo inputs are equipped with a bicolor LED that displays the summed, Prefader signal level with varying intensity green illumination, and also indicates impending channel overload (within 3dB of clipping) by turning red. Clipping is sensed both pre and post fader, so even if the fader is down, you will be informed of any preamp or EQ related overload problems.
¡ master section HPW owner’s manual TM alternate outputs features The HPW has 2 alternate outputs located within the Master module. These outputs are designed to allow the user to select the signal source that is being output. This feature is especailly useful when sending audio for broadcast, recording, an attached room, public spaces or assisted hearing devices.

master section ¡ headphone source The operator can use the headphones to listen to the various signals within the Console.The headphones are normally fed from whatever sources are selected in the Monitor Section. The level is controlled by the Phone Level control (the Monitor level control will not affect the headphone level). When Solo is active, the headphones automatically switch over to the Solo bus. Any channels that are assigned to the PFL or AFL bus will be heard.
¡ master section HPW owner’s manual TM talkback section The operator can use the built-in facilities of the HPW to talk to the main, group, or aux buses in the console. Often times, the operator will need to selectively communicate with a performer, or slate a performance during a recording. 115 115 talkback input This front-panel XLR jack can accept mic-level signals and is equipped with a phantom power option header (internally located behind the XLR jack within the Master module).
master section ¡ power supply - internal internal supply The HPW is equipped with an internal power supply, based on a universal input, switch-mode design. As such, you can power the HPW from any worldwide AC mains voltage from 100 to 240 volts, 50 or 60Hz. Input power is approx 200 watts maximum (56-chan console), so power requirements are minimal. A standard IEC power-inlet socket is used, along with a country-specific line cord, to bring AC power into the Console.
12 power supply HPW owner’s manual TM external power supply - front NOTE: The 2U rack-mount panel can be removed from the chassis if a stand-alone, floor or desktop supply is preferred. Remove the six #8 screws securing the front panel to the chassis. Remove the front panel and store it away, then replace the #8 screws (to fill the threaded holes in the front of the chassis). Attach the supplied feet to the bottom of the chassis in the four indicated positions.
power supply 12 external power supply The style and pinout of the DC Connectors on the HPW are the same as the Crest X-Series of consoles (X-Eight, X-Four, X-VCA, X-Monitor), and the existing X-Series supply CAN be used to power the HPW console.The voltage requirements are the same, but the current demands are less with the HPW. The better (and cheaper) solution for an external supply is to use the supply designed for the HPW, the model XPSSW3.
