Panel Descriptions Wall-Mount Power Vector Front Panel PUSH 1 2 3 1. Input Volume Control Each of the 8 module bays are controlled by an independent volume control. 2. Signal / Clip Indicator A single two-color LED located above each channel’s volume control indicates the audio activity of that channel’s input. Green indicates signal active at the input; red indicates clipping of the input signal. 3.
Panel Descriptions Wall-Mount Power Vector Module Bay (Rear) 1. Module Bays The amplifier has eight module bays, all of which can accommodate input modules, with two bays (bays 7 and 8) that can accommodate either input or output modules. 2. Lo-Cut Switch Slide switch (located in module bay 6) allows roll off of frequencies below 125 Hz. 3.Tone Control Bypass Switch Slide switch (located in module bay 6) allows the effects of the Bass and Treble controls to be bypassed.
Installation Package Contents • Amplifier • Instruction Manual • 2 Screws (M 3 x 8) • 2 Cables • Combined XLR receptacle and phone jack • 6 Screws (M 4 x 8) Mounting A surface-mount (model BBS) or flush-mount (model BBF shown below) back box as well as a WMAD door is required for installation. Refer to the instructions provided with these items for proper installation. (See Components on Back Cover.
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.
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.
Connections COM and GND Terminals 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.
Connections 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 Input Volume 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.
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 provide almost no limiting and is essentially turned off. It will only engage when very large output levels are produced.
