Installation and Operation:
Main/Monitor Combinations:
Another application of the Stereo Mode (see page 8) is using one channel of the amplifier for the house speakers and the
other for the monitors. The MONO/STEREO SWITCHES (#16 & #17) must both be in the OUT position.
Either the binding posts or the Speakon
®
jacks may be used to connect the amplifier to the speakers. See the wiring dia-
gram below for the Speakon
®
jacks.
NOTE: Your speakers may benefit from a low frequency cut, since frequencies below a speaker’s low-end response limit can
cause distortion or even damage. For this reason you might consider using an appropriate Low Cut Frequency (see #19 & #20)
with your speakers. Monitor speakers usually need a low cut for best performance (SPA-1400C only).
