CAUTION: When operating in the BRIDGED mode (particularly when bench testing the amplifier) do not make a ground or any other kind of connection to the amplifier speaker terminals other than those to the individual speakers as shown. Failures caused by inappropriate connections are not covered under the warranty.
Connecting the REMOTE MASTER ON/OFF MUTE CONTROL
As mentioned under "PA435X PANEL AND FEATURE DESCRIPTIONS", the REMOTE MASTER ON/OFF CONTROL inputs (CI1 & CI2) will allow the power to the PA435X to be turned ON, OFF, and MUTED by remotely applied DC Voltages. Fig. 8 illustrates how a PA435X can be switched ON and OFF via the MRC88 Zone 7 & 8 Control Outputs (CO1 and CO2).
On/Off Standby Control:
Whenever a 5 to 30v dc voltage is applied to the TIP of the 3.5mm Stereo jack, the associated Amplifier channel will be activated (Powered ON). When the signal applied to the TIP approaches GND it will put the associated Amplifier channel in STANDBY Mode. If both Amplifier channels are in STANDBY MODE and the front POWER SWITCH left in the OUT position, the entire Amplifier will be powered down (Illuminated LOGO OFF).
Mute Control:
Whenever a 5 to 30v dc voltage is applied to the RING of the 3.5mm Stereo jack, the associated Amplifier channels signal output will be MUTED. When the signal applied to the RING approaches GND it will
