IMPORTANT SAFETY INSTRUCTIONS

• Read and keep these instructions.

• Heed all warnings and follow all instructions contained within this manual.

• Do not use this unit near water.

• Clean only with dry cloth.

• Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

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

• 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.

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

• Only use attachments/accessories specified by the manufacturer.

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

• Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as when the 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.

• Operate the product only with the voltage specified on the unit. Fire and/or electric shock may result if a higher voltage is used.

• Do not modify, kink, or cut the power cord. Do not place the power cord in close proximity to heaters and do not place heavy objects on the power cord and/or the product itself, doing so may result in fire or electrical shock.

• Replace the protective cover over the speaker terminals after installation. Do not touch the speaker terminals as electric shock may result.

• Ensure that the safety ground terminal is connected to a proper ground. Never connect the ground to a gas pipe, as a severe explosion and/or fire may result.

• Be sure the installation of this product is stable, avoid slanted surfaces as the product may fall and cause injury, property damage, electrocution and/or fire.

PRODUCT OVERVIEW

3

Thank you for choosing the Factor Electronics PA-1000/2000 Professional Stereo Amplifier. The PA-1000/2000 amplifiers are designed to provide ultra high quality amplification for multiple professional applications. The PA-1000/2000 employ high current switching mode power supplies SMPS which reduce the amplifier weight, heat, distortion, noise and power consumption while increasing amplifier power output and overall performance. The PA-1000/2000 provide state of the art protection circuitry like thermal, short circuit, output DC offset and power ON/OFF muting to eliminate pops and thumps when powering your audio system. A switchable limiter is also provided which protects the amplifier and connected speakers from input overload conditions. The PA-1000/2000 amplifiers provide front panel LED status indicators for signal present, signal clip, protect mode, parallel mode, bridge mode and power ON mode. Please read this entire manual to get the most from your PA-1000/2000 professional power amplifier.

The PA-1000/2000 kit includes the following parts:

1. 1 x PA-1000/2000 Amplifier

2. 1 x Rack mounting ears

3. 1 x 14awg 115V power cable and extra AC mains fuse

4. 4 x Amplifier rubber feet (for table top operation)

5. 1 x Installation Guide/Operation Manual

PA-1000/2000 INSTALLATION INSTRUCTIONS

5

IMPORTANT: The PA-1000/2000 should be situated in a well ventilated location or position. Do not block the vents on the front/back of the chassis. Proper ventilation is required for normal operation. Do not expose the unit to excessive dust and do not allow dust to build up on the unit and block the vent holes in the chassis. Do not place the PA-1000/2000 directly above or below heat-generating components such as another audio amplifier. Be sure to leave at least 2 inches of space to the sides of the chassis with open air flow above and below the unit.

INSTALLATION:

1. The PA-1000/2000 can be mounted in an equipment rack using the rack kit that is included with the unit.

2. Always disconnect the AC power cord before making any connections.

3. Use good quality 12-14awg 2 conductor stranded copper speaker wire for all speaker connections.

4. Use good quality balanced input cables like the Factor Electronics PRO-XLR cables.

Stereo configuration using four 8ohm speakers. Set the MODE switch to

STE – STEREO. Each channel of the amplifier can broadcast independent sources from input A or B or be used as a high power stereo amplifier.

Parallel configuration using four 8ohm speakers. Set the MODE switch to

PAR – PARALLEL. Input source A will broadcast to both amplifier outputs.

Use this configuration when all speakers must be driven from the same source.

BRIDGE MONO operation. Set the MODE switch to BRI – BRIDGE.

The two independent internal amplifiers will be combined to create a single high power amplifier. This is useful when powering a professional sub woofer. In bridge mode input channel A is used as the source

(channel B controls are disabled). NOTE: Minimum speaker impedance is 4ohms in bridge mode. Speaker wires must be connected to the

+ CH-A (positive) and + CH-B (negative)

Dual Amplifier BRIDGE MONO operation. Set the MODE switch to

BRI – BRIDGE. The two independent internal amplifiers will be combined to create a single high power amplifier. This is useful when powering a professional sub woofer. In bridge mode input channel A is used as the source (channel B controls are disabled). Connect the TRS input to

CH-A on amp 1 and connect an XLR cable to CH-A on amp 2.

NOTE: Minimum speaker impedance is 4ohms. Speaker wires must be connected to the + CH-A (positive) and + CH-B (negative) www.factorelectronics.com

PA-1000/2000 CONSTANT VOLTAGE SYSTEMS 7

IMPORTANT: The PA-1000/2000 amplifiers are capable of driving constant voltage high impedance speaker systems in BRIDGE MONO

Mode (PA-1000) or in STEREO MODE using the PA-2000 where each channel is capable of 1000 watts output per channel. Constant voltage systems are more commonly referred to as 25 volt or 70 volt systems or commercial sound systems. With this type of system all speakers must be connected to a 25 volt or 70 volt transformer which reflects a higher impedance back to the amplifier. This allows multiple speakers to be connected in parallel to the amplifier without exceeding the minimum impedance rating of the amplifier.

The PA-1000/2000 amplifiers are capable of driving a minimum of 4 ohm speaker loads in bridge mono mode. Never connect a combination of 8ohm (no transformer) speakers and 25/70 volt speakers to the same amplifier. Never connect the Left & right channels of the amplifier together. Never combine the – negative channels of the amplifier together. Improper speaker installation can damage the amplifiers and void the warranty. If you are unsure how to connect speakers to the PA-1000/2000 always contact a qualified Factor

Electronics technician before connecting speakers to the amplifiers.

INSTALLATION: Connecting 25/70 volt speakers to the PA-1000/2000 in BRIDGE MONO MODE

Use good quality 14-18awg stranded copper speaker wire. Never run speaker wires parallel to AC wires. If you must cross AC wires always cross at a 90 degree angle. Trim approx 1/4” of insulation from the speaker wire and twist the copper ends. We recommend using the Factor Electronics SPK-4P twist lock speaker wire connectors to avoid shorts in the speaker wire.

1. Set the MODE switch to BRI (BRIDGE)

2. Connect the source to input CH-A.

3. Connect the speaker wires to the SPK-4P connector as follows: positive + to 1+/ negative – to 2+. Now insert and twist the connector.

4. Use parallel wiring to connect the transformer coupled speakers.

5. Each 70 volt speaker reflects an impedance of 5000ohms @ 1 watt, 500ohms @10 watts, 250ohms @ 20 watts & 166ohms @30 watts

6. Divide the number of speakers in the system by the impedance to calculate the minimum impedance of the entire load.

70 Volt transformer coupled speakers tapped @ 10 watts / 60 speakers max = 8.33ohms 70 Volt transformer coupled speakers tapped @ 20 watts / 30 speakers max = 8.33ohms www.factorelectronics.com
