1. Move the N

RIDGED
switch for the zone to the B
RIDGED
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.
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.
NOTE: When a zone is br idged, the source connected to the odd-numbered input channel and the

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.
