Ventilation and Mounting
ModelsV250 andV150
When rack or table mounting modelsV250 andV150, allow a minimum clearance of 1-1/4" on the left side of
the unit for proper ventilation of the fan exhaust and a minimum top and bottom clearance of 1/2". The right
side has no specific clearance requirement. These are minimum acceptable clearances, though the more space
provided on the left side, top, and bottom, the better.
ModelsV100,V60, andV35
When rack or table mounting models V100, V60, and V35, which are passively cooled, allow a minimum
1
clearance of /2" for the bottom (set by the height of the unit’s feet) and a minimum of 1" from the top to other
obstructions. The sides have no specific clearance requirement. These are minimum acceptable clearances,
though the more space provided, both top and bottom, the better.
Rack Mounting
When stacking equipment in a rack, the amplifier should either be on the bottom of the stack or above
equipment that does not produce heat.This will ensure that cool air is available to the unit’s heat sinks.A rack
mount bracket kit (model RPK87)is available for the PowerVector series of amplifiers.
Shelf/Table Mounting
When using a shelf or table mount, the amplifier should stand alone with no equipment on top of it or below
it, especially for theV100,V60, andV35 models. If the amplifier must be stacked with other equipment, care must
be taken to ensure that all the minimum clearance distances are met and that the equipment below the
amplifier produces little significant heat. Rubber feet are installed on the amplifier to allow it to be placed on a
tabletop.
Module Installation
Eight module bays are available to accept Bogen’s new advanced input modules. Module bays 7 & 8 can also
accommodate Bogen’s new advanced output modules, thereby allowing users to customize the amplifier to suit
the needs of the installation. (The bays will not accept Bogen’s older style 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.
- CAUTION -
DO NOT FORCE MODULES
• Modules should slide in easily.
• Output modules will not fit in bays 1-6.
• Output modules can only be installed in bays 7 & 8.
• Output modules have 8 contacts on each side.
• Input modules have 6 contacts on each side.

• Older style Bogen input modules (4 /2" in length) are
not usable in the PowerVector amps.

Modules
Output Modules
Functionality
The PowerVector series of amplifiers accepts Bogen signal-processing output modules, which offer a cost effec-
tive 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 is presented to the power amplifier section.
Up to 2 output modules can be installed in a PowerVector amplifier using module bays 7 & 8 (these bays accept
either output or input modules). When two output modules are installed, their signal-processing effects are
cascaded.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 determined 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
modules 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
included so that the input function of the module bay is not lost when an output module is installed.
Input Modules
Functionality
The PowerVector series of amplifiers accepts Bogen’s new advanced input modules,which provide a wide range
of input types allowing the amplifier inputs to be custom configured in both type and number for a particular
application. Input modules can be installed into 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 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 priority control
signals from other input modules. Each input module also contains circuitry that sends a mute control 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 priority
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
amplifier.

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
speakers to the 25V terminals) and the COM terminal. Make sure the
selector switch is in the TRANS OUT 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 DIRECT OUT
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-
coupled 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 to short the GND to the COM terminal regardless of output
type (Trans or Direct).
Remote Volume Control
Three terminals are provided for remote control of the MasterVolume
control on the front panel.This control is motorized, allowing full con-
trol over the setting of the master volume. Shorting the UP terminal
with the C terminal will rotate the MasterVolume control in a clockwise
direction, increasing the volume level. Shorting the DN terminal to the
C terminal will cause the MasterVolume 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. The Bogen Remote Volume Control
Panel (Model RVCP) provides a simple and elegant means of remote
control. Alternatively, a SPDT spring-loaded, center off switch or two
SPST push-button switches can provide the necessary contacts for
remote control.
Pre-EQ Output
An unbalanced RCA connector provides a buffered signal level output for
use by external equipment.This output signal includes all internal signal
processing, including master volume control, output modules processing,
tone controls, and low-cut filtering. It does not include any external
signal processing that may be provided through the Signal-Processing
Inserts.
Signal-Processing Inserts
A set of unbalanced RCA connectors provides a means to insert
external signal-processing equipment between the output of the Power
Vector Amplifier’s mixer section and its power amp section. The RCA
connector labeled OUT provides a signal from the amplifier’s mixer
section. This output signal encompasses all internal signal processing,
including master volume control, output modules processing, tone
controls,and low-cut filtering.The connector labeled IN provides an input
to the amplifier’s power amplifier section. The internal connection
between the amplifier’s mixer section and power amp section is
automatically broken whenever an RCA plug is inserted into the IN
connector.
7
Mute Control
Each priority bus (High, Medium, and Low) can be externally activated.
This allows priority buses of two or more 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 section on Bridging and illustration on page 8.
Bridging
This connector makes the PowerVector’s mix bus available externally 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 Power Vectors 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 below for additional
information.
System Expansion of Power Vector Amplifiers
Using the bridging RCA connector, it is possible to connect two or more Power Vector amplifiers. It is not
recommended 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.

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 present at the
input. 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 flat to 20 Hz. When driving
speakers using the transformer-coupled output terminals, the Power
Vector 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 output 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
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 at the bottom of the meter. In for average; out for peak.
Power Switch / Power Indicator
TheAC power to the amplifier is controlled by the Power rocker switch.
A red LED indicator lights to confirm the power on status of the
amplifier.

Operation
Rear Panel Controls
Load Selector Switch
A large slide switch above the amplifier’s output barrier strip
determines 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.
A removable switch lock is provided with the amplifier to prevent
accidental changes in switch position.To set the lock, loosen the screw
opposite the desired switch position. Slide the lock under the loosened
screw and align it with the switch.Tighten the screw making sure the
lock has not shifted.
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.
Low-Cut Switch
The Power Vector Amplifier provides a low-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.
