• Instruction Manual  
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 (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 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.

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.
