875HT - EIGHT CHANNEL POWER AMPLIFIER

A/C POWER CONTROL

External control voltage power up ( Local / external switch)

To power-up the 875 using an external control voltage, supply a 4v to 12v A/C or DC control voltage to the ‘IN’ terminals of the “Power-Up” connector. The front panel ‘Power’ switch needs to be off for proper remote operation.

Use paired wire of 22 gauge to 18 gauge between the source device and the 875. The amplifier will now power-up when the control voltage is present (on).

Immediately following power up, the control voltage will appear at the ’OUT’ terminals of connector for the control of other equipment.

Removal of the control voltage causes the 875 to turn ‘off’ and the control voltage at the ‘OUT’ terminals is interrupted.

AC power input

This is a high current plug for the power cord receptacle. Check that the voltage rating at the right of the connector con- forms with your locality. With the front panel power switch in the off position, insert the power cord into the 875, then plug the other end to an appropriate A/C power outlet.

Note:

The ‘OUT’ terminals of the “Power-Up” connector are connected to the ‘IN’ terminals once the 875 has powered-up. The control current that appears across the “OUT” terminals is determined by the source equipment. The carrying cur- rent of the ‘OUT’ relay is 2 amps. The 875 itself draws less than 3 ma from the control current when operating.

875HT specifications
