Do Not Expose This Apparatus To Rain Or Moisture.

Always follow these basic safety precautions when installing and
using the unit:

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with dry cloth.

7. DO NOT block any ventilation openings. Install in accor­dance with the manufacturer’s instructions.

8. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers)
that produce heat.

9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding-type plug has two
blades and a third grounding prong.The wide blade, or the
third prong,are provided for your safety.If the provided plug
does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched,
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.

11. Only use attachments/accessories specified by the manufac­turer.

12. Unplug this apparatus during lightning storms or when
unused for long periods of time.

13. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way,
such as power supply cord or plug is damaged, liquid has
been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not
operate normally, or has been dropped.

CAUTION: TO PREVENT THE RISK OF ELEC­TRIC SHOCK, DO NOT REMOVE COVER (OR
BACK). NO USER-SERVICEABLE PARTS
INSIDE. REFER SERVICING TO QUALIFIED
PERSONNEL.

The lightning flash with arrowhead sym­bol, within an equilateral triangle, is
intended to alert the user to the pres­ence of uninsulated “dangerous voltage”
within the product’s enclosure that may
be of sufficient magnitude to constitute
a risk of electric shock to persons.

The exclamation point within an equi­lateral triangle is intended to alert the
user to the presence of important
operating and maintenance (servicing)
instructions in the literature accompa­nying the appliance.

Panel Descriptions

Wall-Mount Power Vector Front Panel

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 Input Connector

A combination XLR female and 1/4" stereo phone jack connector provides a panel-mounted input.Parts includ­ed, but comes uninstalled.

4. Output Limiter Control with Indicator

Control determines maximum amp output level before limiting takes place. Indicator illuminates when limiting
takes place.

5.Average / Peak Switch

This switch determines whether the LED Output Meter registers the average or peak level of the amplifier’s
output.

6. LED Output Level Meter

An 11-segment LED output level meter monitors the output level of the power amplifier.

7.Tape Out

RCA unbalanced signal level output post bass, treble, and master controls.

8. Bass Control

Controls the amount of cut or boost of bass frequencies below 100 Hz.

9.Treble Control

Controls the amount of cut or boost of treble frequencies above 10 kHz.

10. Master Volume Control

Controls overall level of mixed input signals.

11. Power Switch

Controls AC power to the amplifier. Illuminates when ON.

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. Low-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.

Wall-Mount Power Vector Connector Board (Rear)

1.Trans Output / Direct Out Selector

Allows selection of either transformer-coupled outputs (70V, 25V, and 8-ohm) or a direct low-impedance
(4-ohm minimum) output.

2. Speaker Output Barrier Strip

A terminal barrier strip, with clamping washers, provides connections for speaker loads.

3. Master Mute Terminals

These two terminals, when shorted together, mute the output from all modules installed regardless of their
priority settings.

4. Remote Volume Control Terminals

Three terminals are provided for connection of an RVCP remote volume control panel to control the amplifi­er’s motorized Master Volume Control.
