SONAMP® 875D SE 8-CHANNEL AMPLIFIER

OFF (Bypass) Mode

When a zone’s AUTO and VOLT Auto-On Trigger switches are both set in the OFF position, the AUTO-ONcircuitry is bypassed and the amplifier’s front-panel POWER button will turn all zones ON and OFF simultaneously (see Figure 2, on page 5).

The EXTERNAL TRIGGER connectors feature flip-up levers similar to the ones used on the speaker connectors:

1.Open the levers for the zone’s EXTERNAL TRIGGER inputs.

2.Insert the control wires into the appropriate openings in the connector.

3.Close the levers.

The front-panel ZONE STATUS LEDs indicate if BBE processing is being applied to a zone (see Figure 3, on page 7).
