SONAMP® 875D SE 8-CHANNEL AMPLIFIER

6.Press the removable connector into the corresponding zone speaker connector on the amplifier until it locks into place.

•The removable connectors will only fit one way on the amplifier.

CAUTION: Always provide sufficient slack in wires to avoid tension. Always contain any excess wire to prevent tripping hazards.

Speaker Connections for Bridged Operation (see Figures 11 & 12)

The 875D SE can operate with any pair of channels (zone) in the single-channel bridged mode, which delivers 300 watts RMS into an 8-ohm speaker. Be sure the speaker is rated to handle this increased output power .

IMPORTANT: The minimum speaker impedance for Bridged Operation is 8 ohms. Do not operate a zone in the Bridged mode into a speaker that is less than 8 ohms nominal impedance.

1.Move the NORMAL/BRIDGED switch for the zone to the BRIDGED position (see Figure 11).

2.Strip no more than ¼” of insulation from the speaker leads. Twist the strands or tin the exposed wire with solder to ensure that there are no stray strands. (Stray strands that touch each other or touch the amplifier chassis can cause a short-circuit that can damage the amplifier.)

3.The Sonamp 875D SE has a removable 4-wire speaker con- nector for each zone that can accept wire up to 14AWG. Flip the outer two levers up to open the connector terminals.

4.Insert the single speaker’s “+” and “–” speaker leads into the two outer terminal openings on the 4-wire speaker connector. Observe the polarity shown in the chassis markings above the connector (see Figure 12).

5.After making sure that there are no stray wires touching each other, flip the two levers down to lock the wires in the terminal.

•The removable connectors will only fit one way on the amplifier.

NOTE: When a zone is bridged, the source connected to the odd - numbered input channel and the I N P U T A S S I G N M E N T DIP switches for the odd - numbered channel function . The input connected to the even - numbered channel and the switches for the even - numbered channel are disabled .
