PRODUCT OVERVIEW
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 D 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.

PA-1000/2000 INSTALLATION INSTRU TIONS
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 A 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.
S ereo configura ion 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 configura ion 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.

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

PA-1000/2000 ONSTANT VOLTAGE SYSTEMS
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. onstant
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: Connec ing 25/70 vol speakers o he PA-1000/2000 in BRIDGE MONO MODE
Use good quality 14-18awg stranded copper speaker wire. Never run speaker wires parallel to A wires. If you must cross A 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. onnect the source to input H-A.
3. onnect 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 Vol ransformer coupled speakers apped @ 10 wa s / 60 speakers max = 8.33ohms 70 Vol ransformer coupled speakers apped @ 20 wa s / 30 speakers max = 8.33ohms
