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 (4Ω) speaker load can be driven directly without transformer coupling by connecting the load
to the 4Ω terminal 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.
9
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.
