Xantech PA435X 35W Four Channel Amplifier


Xantech PA435X 35W Four Channel Amplifier

The Xantech PA435X is a  four channel 35-watt power amplifier. This permits the PA435X to drive 2-zones in a multi-zone system -- each with a 35-watt stereo amplifier per zone.  Either pair of amplifiers can be bridged to allow several channel and power output capabilities. It can be configured into three power packages as follows:

  • Four 35-watt amplifiers. (4 Mono speaker outputs or 2 Stereo Zone outputs)
  • One 70 and two 35-watt amplifiers. (1 Mono 70 Watt and 1 Stereo 35-watt output)
  • Two 70-watt amplifiers (single Zone Stereo 70-watt output)

Remote ON/OFF Control Jacks (C1 & C2). These 3.5mm Stereo Mini Jacks allow the PA435X to be powered on and off and muted by a positive DC voltage ranging between 4 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 PA435X ON and OFF automatically with zone ON/OFF commands.

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.). When set to the 1:30 position, this will match the sensitivity level of the standard Amplifier output setting of the MRC88.

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: This feature protects the PA435X 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.

Rated THD < 0.08%, Damping Factor: (@ 50Hz, 8 ohms, rated power) > 100, S/N Ratio: A-Weighted (ref. to rated power) > 96dB
