OPERATING MODES
STEREO OPERATION :
Page 9/ Figure 17 details an example of a typical stereo set-up. Connect your inputs into channels one and two of the amplifier.
Connect your speakers to the outputs on the rear of the amplifier. Be sure that your front gain controls are turned down to their lowest level (fully counter-
clockwise). Turn your amplifier on. Turn your input source level up. Use your front gain controls to regulate the output volume. Be sure not to raise the volume to
the clip level, however an intermittent clip signal is acceptable.
MONO BRIDGE OPERATION :
Page 10/ Figure 18 details a mono bridge set-up. Be sure your amplifier and all other audio equipment are powered
down. Flip the Parallel/Stereo/Mono Bridge switch to the Mono Bridge position. Connect input signal to channel one. Connect your speaker across the red
output binding post on the rear of your amplifier. Turn your equipment on (your amplifier should always be the last item you turn on). Apply an input source
signal to your amplifier. Use the channel one gain control to regulate your amplifier output.
PARALLEL MONO :
Parallel ties the two channel line inputs together, so that they will both be driven by the same signal, without the need for external
jumpers or wiring. Both amplifier channels will operate independently. Though they carry the same signal, their gain controls affect only their respective
channels, and they both must use their respective speaker outputs. Never attempt to parallel the speaker outputs, this may cause serious damage to your
amplifier! This mode is recommended when using the NA-13600/NA-17600/NA-21600 to run bass speakers, to achieve better low end. To run in parallel mono
mode connect your system as you would if you were going to run in stereo mode. Then flip the mode switch to Parallel. Be sure the amplifier is off or the power
is disconnected before making any changes.
