Xanrech PA4100X 100 Watt Four-Channel Power Amplifier
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.
Auto Protection Circuit. This feature protects the PA4100X if a short or very low impedance is detected at the speaker terminals with each amplifier pair protected separately. Normal operation is restored automatically within 3 to 4 seconds after the short is removed.
