GENERAL INFORMATION

To enhance the ease of installation and obtain optimum performance from the PA4100X, we recommend that you first become familiar with all its features and special capabilities by studying the descriptions and instructions in this manual.

The PA4100X was designed to meet the audio power amplifier needs of custom installed multi-zoned systems with high sonic quality and hi power output. It is a 4 Channel amplifier that is primarily intended to interface with the MRC88 Whole-house Audio Video Entertainment System for Zones 7 and 8 Preamp outputs or for Sub-Zone amplification of zones 1-6. It may also be used as a standalone 2-zone amplifier. Specific features and technology are as follows:

Cost/Size Efficiency. The PA4100X features four 100-watt power amplifiers. This permits each PA4100X to drive 2- zones in a multi-zone system -- each with a 100-watt stereo amplifier per zone.

Remote ON/OFF Control Jacks (C1 & C2). These 3.5mm Stereo Mini Jacks allow the PA4100X to be powered on and off and muted by a positive DC voltage ranging between 5 and 30 volts (11mA @ 12 V). Specifically, when interfaced with the Control Out jacks of zones 7 & 8 on the MRC88 (labeled CO1 and CO2), it permits the MRC88 to power the PA4100X ON and OFF automatically with zone ON/OFF commands or any 12VDC control signal.

Input Level Flexibility. The input level (sensitivity range) is 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.).

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

Peak/Clip LED Indication: Whenever either amplifier channel output starts to enter a clipping state, the channels front panel LED will illuminate RED. After the amp stops clipping the LED will return to its normal state 5-6 seconds after clipping stops.
