caUTiON: Never change the position of
the Mode Switch while the amplifier
power is on. See Section 5.2.2 for more
information.
3.6.1 Dual 8/4 Mode
Typical input and output wiring, along with level
control and Mode Switch settings are shown in
Figure 3.6. Make sure the Mode switch is set to
the “Dual 8/4” position.
INPUTS: Connect input wiring for each channel.
OUTPUTS: Maintain proper polarity (+/–) on
output connectors.
Connect the Channel 1 speaker’s positive (+) lead
to amplifier Channel 1 positive terminal; repeat
for negative (–). Repeat each channel wir ing as
for Channel 1. Refer to Section 3.5 for output
connector pin assignments.
3.6.2 Dual 70V Mode
caUTiON: Never change the position of
the Mode Switch while the amplifier
power is on. See Section 5.2.2 for more
information.
Typical input and output wiring, along with level
control and Mode Switch settings are shown in
Figure 3.7. Make sure the Mode switch is set to
the “Dual 70V” position.
INPUTS: Connect input wiring for each channel.
OUTPUTS: Maintain proper polarity (+/–) on
output connectors.
Connect Channel 1 positive (+) speaker load to
Channel 1 positive terminal of amp; repeat for
negative (–). Repeat each channel wiring as for
Channel 1. Refer to Section 3.5 for output
con nector pin assignments.

3.6.3 Bridge-Mono 16/8 Mode
caUTiON: Never change the position of
the Mode Switch while the amplifier
power is on. See Section 5.2.2 for more
information.
Typical input and output wiring, along with level
control and Mode Switch settings are shown in
Figure 3.8. Make sure the Mode switch is set to
the “Bridge 16/8” position.
INPUTS: Connect input wiring only to the lower-
(odd-) numbered channel pair.
OUTPUTS: Connect the speaker across the
posi tive terminals of each channel pair. Do not
use the negative terminals of the channel pair
when the pair is being operated in Bridge-Mono
mode.
NOTe: When operating the channel pair in
Bridge-Mono mode, turn down (full CCW) the
level control for the higher (even)-numbered
channel of the channel pair. The lower (odd)-
numbered level control works both channels.
3.6.4 Bridge-Mono 100V Mode
caUTiON: Never change the position of
the Mode Switch while the amplifier
power is on. See Section 5.2.2 for more
information.
Typical input and output wiring, along with level
control and Mode Switch settings are shown in
Figure 3.9. Make sure the Mode switch is set to
the “Bridge 100V” position.
INPUTS: Connect input wiring only to the lower-
(odd-) numbered channel pair.
OUTPUTS: Connect the speaker across the
posi tive terminals of each channel pair. Do not
use the negative terminals of the channel pair
when the pair is being operated in Bridge-Mono
mode.
NOTe: When operating the channel pair in
Bridge-Mono mode, turn down (full CCW) the
level control for the higher (even)-numbered
channel of the channel pair. The lower (odd)-
numbered level control works both channels.
