Modules  
Module Installation  
Eight module bays are available to accept Bogen’s new advanced plug-in input modules. Module bays 7 & 8 can  
also accommodate Bogen’s new advanced plug-in output modules, thereby allowing users to customize the  
amplifier to suit the needs of the installation.  
(Note:The bays will not accept Bogen’s older style D-Series plug-in modules.)  
Before installing a module, read the instructions included with the module and make the desired jumper setting  
changes.  
The modules are installed by simply sliding them along the card guides inside the module bays until the  
faceplate firmly sits against the chassis, then use the two screws supplied with the module to secure it to the  
chassis.  
Modules should slide in easily.  
Output modules can only be installed in bays 7 & 8. (Output modules will not  
- CAUTION -  
fit in bays 1-6.)  
DO NOT FORCE MODULES  
Output modules have 8 contacts on each side of connector.  
Input modules have 6 contacts on each side of connector.  
Older style Bogen (D-Series) input modules (4-1/2" in length) are not usable  
in any PowerVector amp.  
Output Modules  
Functionality  
The Wall-Mount Power Vector series of amplifiers accepts Bogen plug-in output modules, which offer a cost  
effective and convenient way to add specific signal processing capability into a system.When an output module  
is installed, the mix bus signal is automatically rerouted through the output module, whose capabilities further  
process the signal before it enters the power amplifier section.  
Up to 2 output modules can be installed in a Power Vector amplifier using module bays 7 & 8 (or these bays  
can accept input modules). When two output modules are installed, their signal processing effects are cascad-  
ed.The mix bus signal will first pass through the output module in module bay 7 and then through the output  
module in bay 8. In some instances, the order in which the signal processing is applied is important and can be  
achieved by the module installation order.  
Output modules automatically insert themselves into the signal path between the mix bus and power amp  
stage, so no further connections are required beyond simply inserting the modules. Most Bogen output mod-  
ules include an unbalanced, Hi-Z input.This input feeds directly to the amplifier’s mix bus through the front level  
control for the particular module bay and is not processed by the output module directly.The input is includ-  
ed so that the additional input function of the module bay is not forfeited when an output module is installed.  
Input Modules  
Functionality  
The Wall-Mount PowerVector series of amplifiers accepts Bogen’s new advanced plug-in input modules, which  
provide a wide range of input types allowing the amplifier inputs to be custom configured in both type and num-  
ber for a particular application. Input modules can be installed in any of the 8 module bays and do not have to  
be installed in any particular bay order.The front panel volume control for that number bay will control the mix  
level of that input module. In addition to a host of module specific features, each input module has a priority  
jumper section for creating a priority hierarchy between different inputs installed in the amplifier.  
Priorities  
The Wall-Mount Power Vector series of amplifiers allows inputs to be prioritized at four different levels.The  
Bogen input modules contain circuitry that can cause their outputs to be muted in response to higher priori-  
ty control signals from other input modules. Each input module also contains circuitry that sends a mute con-  
trol signal out to other modules when it becomes active (all input modules become “active” when they receive  
an audio input).Active modules may be prevented from sending their audio onto the mix bus by a higher pri-  
ority module that is also active.  
Input priorities are set through a simple jumper field on the module. It is also possible not to assign a priority  
level to an input module. By doing so, that module will never be muted by another input module in the ampli-  
fier.The unassigned inputs will, however, be muted by the amplifier’s Master Mute input.

Connections  
Speakers  
Transformer-Coupled Speaker Connections  
Transformer-coupled, constant voltage speaker loads are connected to their respective load type (i.e., 70V  
speakers to the 70V terminal, 25V speaker systems to the 25V terminals) and the COM terminal. Make sure  
the selector switch is in the TRANS position. A separate 8-ohm terminal is provided to drive 8-ohm  
(low-impedance) speakers through an output transformer tap.  
The speaker terminals can accept up to a #10 spade lug and have integral clamping plates that make wiring  
easier.  
4-Ohm Low-Impedance Speaker Connections  
A low-impedance (4) speaker load can be driven directly without transformer coupling by connecting the load  
to the 4terminal and the GND terminal. Make sure the selector switch is in the DIR position.  
Bypassing the output transformer and driving the speaker load directly provides the advantage of better bass  
response.To maximize the power delivered to the speakers, their combined load impedance should be 4 ohms.  
Connecting higher load impedances is electrically acceptable,but the mismatch in load impedance will cause the  
speaker load to only receive a portion of the power that the amplifier is capable of delivering. It is not  
acceptable to connect low-impedance speakers to the 70V and 25V outputs.

Connections  
COM and GNDTerminals  
A shorting jumper typically connects the COM and GND terminals of the  
amplifier together. The COM terminal is a common lead from the output  
transformer. For the transformer-coupled speaker output to work, one of the  
speaker load leads must be connected to this terminal.The GND terminal is  
a connection to the system’s electrical ground and used when driving loads in  
the Direct Out mode.  
Connecting the GND to the COM terminal when using the transformer-cou-  
pled outputs references the transformer output to ground. Disconnecting the  
GND terminal from COM allows the transformer output to float electrically.  
This is sometimes useful under certain conditions where a ground connection  
is undesirable. It is generally a good idea, however, to short the GND to the  
COM terminal regardless of output type (Trans or Direct).  
Remote Volume Control  
These terminals are provided for remote control of the MasterVolume con-  
trol.This control is motorized, allowing full control over the setting of the  
master volume. The Bogen Remote Volume Control Panel (model RVCP)  
provides a simple and elegant means of remote control. Shorting the UP ter-  
minal with the C terminal will rotate the Master Volume control in a clock-  
wise direction, increasing the volume level. Shorting the DN terminal to the  
C terminal will cause the Master Volume control to rotate in a counter-  
clockwise direction and decrease the level of the MasterVolume control.The  
impedance of the shorting connections must be less than 100 ohms in order  
to operate the control.  
Mute Control  
Each priority bus (High, Medium, and Low) can be externally activated.This  
allows priority buses of two or more Wall-Mount Power Vector units to be  
linked together for system expansion purposes. A particular mute  
priority can be externally forced by shorting that priority’s bus terminal to  
the C terminal of the Mute Control (the C terminal is the system ground).  
Forcing the H priority bus this way will mute all modules except for modules  
set for priority level 1 (highest priority). Forcing the M priority bus will mute  
modules set for priority levels 3 or 4, but not levels 1 or 2, and forcing the  
L priority bus will only mute modules set at priority level 4. See System  
Expansion of PowerVector Amplifiers section and illustration on page 8.  
Bridging Mix Bus  
This connector makes theWall-Mount PowerVector’s mix bus available exter-  
nally and allows the connecting of Power Vector units for system expansion  
and simple room combining.  
This function is bi-directional. Any signal received will be amplified and any  
signal sent can be used by another PowerVector amp.The signal levels at the  
bridging jack will drop by one-half with two PowerVectors tied together and  
by two-thirds with three units tied together. Because of the attenuation of the  
bridging signal, due to the signal loading of other Power Vectors, it is not  
recommended that more than three units be connected together. See Mute  
Control section and the illustration on the next page for additional information.

Connections  
System Expansion of Power Vector Amplifiers  
Using the bridging RCA connector, it is possible to connect two or more PowerVector amplifiers. It is not rec-  
ommended that more than three amplifiers be bridged together due to bridging loss. When  
connecting mute control functions, make certain that the wiring is consistent (H to H, M to M, and so forth).  
See illustration below.  
Note: When connecting mute control functions  
between amplifiers, make certain that the wiring is  
consistent (H to H, M to M, and so forth).

Operation  
Front Panel Controls & Indicators  
InputVolume Controls  
Each input module may be individually controlled by its corresponding volume  
control knob.  
Signal / Clip Indicator  
A single LED located above each channel’s volume control indicates the audio  
activity of that channel’s input. Green indicates signal is being applied to the  
mix bus.Red indicates that the input signal coming from the input module into  
the amp is clipping and distorted.This is caused by either an input signal that  
is too high or an input module volume control (gain) that is set too high.  
Bass andTreble Controls  
The treble control has a cut/boost range of +/- 10 dB at frequencies above 10  
kHz and provides a roll off after 20 kHz to reduce gain above the audio range.  
The bass control has a cut/boost range of +/- 10 dB at frequencies below 100  
Hz.When driving speakers using the direct-coupled output terminals, the bass  
filter’s response is constant to 20 Hz.When driving speakers using the trans-  
former-coupled output terminals, the amplifier automatically changes the bass  
filter’s response to a bandpass shape to reduce the level of bass frequencies  
below 40 Hz.This filter shape helps to avoid overdriving the speaker’s coupling  
transformer with low frequency signals that may cause noticeable distortion  
due to magnetic saturation of the transformer’s core.  
MasterVolume Control  
The overall volume level of the amplifier is set by a Master Volume control.  
The Master Volume control is motorized and can be controlled by manually  
adjusting the knob or by a remotely-mounted control station. Connections  
and requirements for the remote control station (optional accessory) are  
described in the Connections section, under RemoteVolume Control.  
Average / Peak Switch & LED Output Meter  
The LED Output Meter is an 11-segment meter that registers either the  
average or the peak level of the amplifier’s output signal. A red indicator is  
provided at the +3 dB level to indicate amplifier clipping.Amber indictors at  
the 0 dB and -3 dB levels indicate high amplifier output levels.The remaining  
8 indicators (green) provide an indication of the output signal’s dynamics.The  
meter can be set to read either the average output signal level or the peak  
output signal levels by using the Average / Peak Switch to the left of the meter.  
In is average; out is peak.  
Power Switch / Power Indicator  
The AC power to the amplifier is controlled by the Power rocker switch,  
which illuminates when power is applied.

Operation  
Output Limiter  
The Output Limiter control sets the threshold at which the unit hard  
limits the output signal. Once the Limiter's threshold is exceeded, the  
output signal is prevented from increasing any further.With the control  
set to the Min position (fully counterclockwise), the Limiter will pro-  
vide almost no limiting and is essentially turned off. It will only engage  
when very large output levels are produced. As the control is turned  
clockwise, more limiter function will be allowed and the output level  
necessary to engage the Limiter decreases.  
Typically,the Limiter is set to prevent clipping caused by overdriving the  
amplifier beyond its maximum output level.This setting is established by  
using both the Output Level Meter and the Limiter LED.  
First, adjust the amplifier’s output level until the Output Level Meter  
registers in the amber region.Then, adjust the Output Limiter control  
until the Limiter LED illuminates intermittently. The LED associated  
with the Limiter illuminates when the Limiter is engaged. If the output  
level of the amplifier exceeds this point, then the Limiter will engage,  
thereby keeping the Output Level Meter in the amber region. The  
Limiter can also be set to restrict the amplifier's output level to a  
desired level below the amplifier's maximum level to provide a means  
of limiting the system's volume level. In this case, the amplifier is driven  
to the desired output level and then the Limiter control is adjusted so  
that it begins to engage. In general, input and master controls should be  
set so that the Limiter engages as little as possible.  
Rear Panel Controls  
Trans Output / Direct Out Selector Switch  
A large slide switch next to the amplifier’s output barrier strip deter-  
mines transformer-coupled or direct output operation.The setting of  
this switch controls which amplifier output terminals are active and  
what type of filter shape will be used for the bass control. See the  
Connections section for more information about the load selector  
switch.  
Other Controls (Located In Module Bay 6)  
Tone Control Bypass Switch  
A slide switch that can bypass the effects of the Bass  
and Treble controls is located on the back plane of  
module bay 6. It is sometimes desirable to bypass  
the tone controls when other forms of system  
equalization are used.A screwdriver can be used to  
set the switch. The switch must be set before a  
module is installed in this bay.  
Lo-Cut Switch  
The Power Vector Amplifier provides a lo-cut filter  
that rolls off frequencies below 125 Hz. The slide  
switch for this function is located on the back plane  
of module bay 6. A screwdriver can be used to set  
the switch.The switch must be set before a module  
is installed in this bay.
