Panel Descriptions VMIX Front Panel 1. Input Volume Controls Each of the 8 inputs is controlled by an independent volume control. 2. Signal / Clip Indicators A single two-color 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 clipping of the input signal. 3. Treble Control Controls the amount of cut or boost of treble frequencies above 10 kHz. 4.
Panel Descriptions VMIX Rear Panel 1. AC Receptacle A grounded, unswitched AC convenience receptacle with a 500W maximum capacity is provided for external equipment. 2. Unbalanced Output Jack Provides an unbalanced output for connection to an auxiliary or high-impedance input. 3. Bridging Jack An RCA connector that allows the bridging of Power Vector products together for system expansion. 4.
Installation Package Contents • Power Vector Mixer • Instruction Manual • Module Covers (8) • 12 mm Module Cover Screws (16) Mounting Rack Mounting When stacking equipment in a rack, the mixer should either be on the bottom of the stack or above equipment that does not produce heat. A rack mount bracket kit (model RPK87) is available for the Power Vector mixer. Shelf/Table Mounting When using a shelf or table mount, the mixer should stand alone with no equipment on top of it or below it.
Modules Output Modules Functionality The Power Vector mixer accepts Bogen signal-processing 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 is presented to the power mixer section.
Connections Unbalanced Output The VMIX includes an unbalanced output for connection to an auxiliary or high-impedance input using an RCA connector. Output level is 0 dBµ when meter reads “0”. Maximum output is +20 dBµ. Balanced Output Three terminals are provided for the transformer balanced output of the Power Vector mixer. Note: The output signal level is selectable for +4 dBµ, -10 dBµ, or -50 dBµ (see Page 9).
Connections Mute Control Each priority bus (High, Medium, and Low) can be externally activated. This allows priority buses of two or more Power Vector products 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).
Operation Front Panel Controls & Indicators Input Volume Controls and Signal / Clip Indicator Each input module may be individually controlled by its corresponding volume control knob. 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 mixer is clipping and distorted.
Operation Rear Panel Controls Balanced Out Switch A three-position slide switch selects the signal level of the balanced output. Output levels of +4 dBµ, -10 dBµ, and -50 dBµ are available.The indicated output level corresponds to “0” on the level meter. 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.
