Important Safety Information

WARNING: To Reduce The Risk of Fire Or Electric Shock, 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.

IMPORTANT

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

Power Vector Front Panel

1. Input Volume Control

Each of the 8 inputs is 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 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. Bass Control

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

5. LED Output Meter

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

6.Average / Peak Switch

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

7. Master Volume Control

Controls overall level of mixed input signals.

8. Power Indicator

An LED indicates AC power status.

9. Power Switch

Controls AC power to the amplifier.

Panel Descriptions

Power Vector Rear Panel

1.AC Receptacle

A grounded, unswitched AC convenience receptacle with a 500W maximum capacity is provided for external equipment.

2.AC Line Cord and Circuit Breaker

A grounded, 3-wire AC line cord provides power to the amplifier and is protected by a resettable circuit breaker.

3.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.A locking device is included to avoid accidental switching.

4. Speaker Output Barrier Strip

A 5-position barrier strip, with clamping washers, provides connections for speaker loads.

5. Mute Control Terminals

Provides access to mute buses for external control and system expansion.

6. Remote Volume Control Terminals

Three terminals are provided for connection of a remote station to control the amplifier’s motorized Master Volume Control.

7. Low-Cut Switch

A slide switch (located in module bay 6) that allows roll off of frequencies below 125 Hz.

8.Tone Control Bypass Switch

A slide switch (located in module bay 6) that allows the effects of the bass and treble controls to be bypassed.

9. 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.

10. Bridging Jack

An RCA connector that allows the bridging of Power Vectors together for system expansion.

11. Pre-EQ Output

An unbalanced RCA buffer output whose signal includes all volume controls, tone controls, and output module signal processing, but before (pre-EQ) any external signal-processing equipment connected to the SignalProcessing Insert jacks.

12. Insert Jacks

A pair of RCA connectors allow external equipment to be inserted between the pre-amp output and the power amp input. Inserting a plug into the jack labeled “IN” automatically breaks the internal connection between the amplifier’s pre-amp section and power amp section.The insert connections are unbalanced.
