GENERAL INFORMATION

To enhance the ease of installation and obtain optimum performance from the PA1235X, we recommend that you first become familiar with all its features and special capabilities by studying the descriptions and instructions in this manual.

The PA1235X was designed to meet the audio power amplifier needs of custom installed multi-zoned systems with high sonic quality. It's 12-11-10-9-8-7-6 multi-channel capability permits a wide variety of other uses as well, such as surround sound home theater applications. Specific features and technology are as follows:

Cost/Size Efficiency. The PA1235X features twelve 35-watt power amplifiers. This permits each PA1235X to drive 6-zones in a multi-zone system -- each with a 35-watt stereo amplifier per zone. The rack-mount design, plus multiple amplifiers in a single package, delivers high quality at a reasonable price.

Input Level Flexibility. The input levels are individually adjustable (per stereo pair) from a low of 0.2 volts up to 3 volts. This gives the installer the ability to adjust the overall gain of the system or zone. For instance, there may be a need to adjust the amplifier to deliver a controlled, maximum sound level into a zone when the volume control on the preamp is set to maximum. This would act as a volume limiter for any particular zone (i.e. to prevent the kids from over-driving wall speakers, etc.).

12-11-10-9-8-7-6 Output Flexibility. Each pair of amplifiers can be bridged to allow several channel and power output capabilities. It can be configured into four power packages as follows, which gives the PA1235X added use in many other applications, such as driving surround sound speaker systems in addition to multi-room:

ξ Twelve 35-watt amplifiers - 12 total.

ξ One 80 and ten 35-watt amplifiers - 11 total. ξ Two 80 and eight 35-watt amplifiers - 10 total. ξ Three 80 and six 35-watt amplifiers - 9 total. ξ Four 80 and four 35-watt amplifiers - 8 total. ξ Five 80 and two 35-watt amplifiers - 7 total. ξ Six 80-Watt amplifiers - 6 total.

Low Impedance Capability. Each amplifier is 4-Ohm safe under music conditions in stereo mode and 8-Ohm safe when bridged. This means, for instance, that you can drive two pairs of 8-Ohm speakers in stereo mode in each zone with ease.

Auto Protection Circuit. Protects the PA1235X if a short circuit or very low impedance is detected at the speaker terminals. Each amplifier pair is protected separately, with an LED indicator showing which pair is in protection. Normal operation is restored automatically within 3 to 4 seconds after the short is removed.
