-- 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 &... - Page 4 Page 4 Model PA4100X 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.

STANDBY MODE: With the POWER SWITCH left in the IN position (and the CI switch set to ON) the 2 channels of PA4100X may be controlled remotely from the MRC88 via the CI1 and CI2 Control Inputs (or any Voltage Control Signal). When both channels enter STANDBY Mode the front LEDS will turn off leaving the amplifier in a low current sleep mode. - Page 6 6. Line Inputs. These RCA-type jacks are the audio inputs for each of the amplifier pairs. Connect them to the Preamp Output jacks of Zone 7 & 8 of the MRC88 (or other driving preamp output) with good quality RCA-type patch cables. Note that the inputs are marked LEFT-A-RIGHT, LEFT-B-RIGHT signifying the stereo channel pairs.

When connected to the C01 and C02 jacks from Zones 7 & 8 on the Xantech MRC88, this will allow remote Power ON/OFF control directly from the MRC88 System Controller. This allows the ‘A’ & ’B’ amplifier channel pairs to be individually controlled by Zones 7 &...

Page 8: Installation - Physical Location And Mounting
PA4100X of obstructions! When mounting the PA4100X, you should plan its location carefully. Pay close attention to each of the following factors: 1. The amplifier is convection cooled. That is, it depends on the natural free flow of air up through the slot perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate cooling. -
Page 9: Connecting The Pa4100X
Be sure to allow enough strain relief for the leads and dress them in such a manner so as not to block airflow. 7. The PA4100X is designed for shelf mounting on flat horizontal surfaces. When mounting into a 19" rack, use an appropriate rack kit. -
Page 10: Speaker Phasing
CONTROL inputs (CI1 & CI2) will allow the power to the PA4100X to be turned ON, OFF, and MUTED by remotely applied DC Voltages. Fig. 7 illustrates how a PA4100X can be switched ON and OFF via the MRC88 Zone 7 & 8 Control Outputs (CO1 and CO2) or other control source. - Page 11 Model PA4100X Page 11 PA435X -- -- -- -- Figure 7: Using the PA4100X REMOTE MASTER ON/OFF CONTROL Terminals © 2003 Xantech Corporation...

PA4100X is powered ON. Similarly, when either Zone is powered down, the associated amplifier pair on the PA4100X is put into STANDBY Mode. When both Zones (7 & 8) are powered down, the PA4100X will either go into STANDBY Mode on both amplifier pairs or will be POWERED OFF depending upon the position of the front panel POWER/STANDBY button (IN = STANDBY;... -
