WARNING:To prevent injury, this apparatus must be securely attached to the wall in accordance with the installation instructions.

Front Panel Input ConnectorIf desired, a front panel mounted combination female XLR and 1/4″ stereo phone jack can be installed. A white screened area is provided on the front of the amplifier, below the connector, to identify the connector’s purpose and associated input number. Remove the filler cap in the upper left-hand corner of the front panel and install the combination jack as shown in the figures below. Either or both of the connector styles on the jack can be wired to any user-supplied module with included cables. The labeling below the two cable connectors on the PCB identifies corresponding connectors on the combo jack.

Module InstallationEight 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.

CAUTIONDO NOT FORCE MODULES

Modules should slide in easily.
Output modules can only be installed in bays 7 & 8. (Output modules will not fit in bays 1-6.)
Output modules have 8 contacts on each side of the connector.
Input modules have 6 contacts on each side of the connector.
Older style Bogen (D-Series) input modules (4-1/2″ in length) are not usable in any Power Vector 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 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 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 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 additional input function of the module bay is not forfeited when an output module is installed.

Input ModulesFunctionality

The Wall-Mount Power Vector 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 number 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.

PrioritiesThe 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 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. The unassigned inputs will, however, be muted by the amplifier’s Master Mute input.

Connections

SpeakersTransformer-Coupled Speaker ConnectionsTransformer-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 ConnectionsA 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.

Typical connections to a 70V transformer-coupled speaker

Typical connections to a low-impedance (non-transformer-coupled) speaker load

COM and GND TerminalsA 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, however, to short the GND to the COM terminal regardless of output type (Trans or Direct).

Remote Volume ControlThese terminals are provided for remote control of the Master Volume control. 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 terminal with the C terminal will rotate the Master Volume control in a clockwise direction, increasing the volume level. Shorting the DN terminal to the C terminal will cause the Master Volume control to rotate in a counterclockwise direction and decrease the level of the Master Volume control. The impedance of the shorting connections must be less than 100 ohms in order to operate the control.

Mute ControlEach 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 Power Vector Amplifiers section and illustration.

Bridging Mix BusThis connector makes the Wall-Mount Power Vector’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 Power Vector 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 on the next page for additional information.

System Expansion of Power Vector AmplifiersUsing 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 & IndicatorsInput Volume ControlsEach input module may be individually controlled by its corresponding volume control knob.

Signal / Clip IndicatorA 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 and Treble ControlsThe 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 transformer-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.

Master Volume ControlThe 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 Remote Volume Control.

Average / Peak Switch & LED Output MeterThe 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 indicators 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 IndicatorThe AC power to the amplifier is controlled by the Power rocker switch, which illuminates when power is applied.

Output LimiterThe 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 provide 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 ControlsTrans Output / Direct Out Selector SwitchA large slide switch next to the amplifier’s output barrier strip determines transformer-coupled or direct output operation. The setting ofthis switch controls which amplifier output terminals are active andwhat type of filter shape will be used for the bass control. See theConnections section for more information about the load selectorswitch.Other Controls (Located In Module Bay 6)Tone Control Bypass SwitchA 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 SwitchThe 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
