Installation and Operation:
Stereo Operation:
The SPA-1400/1400Ccan be used in the Stereo Mode as two separate power amplifiers, each capable of driving loads down
to 2 ohms. Each channel operates independently and has its own input connectors, sensitivity level controls, signal indicator
LEDS, automatic limiter, fault protection circuitry, power amp, and speaker outputs. In the Stereo Mode, the MONO/STEREO
SWITCHES (#16 & #17) must both be in the OUT position.
One application of the Stereo Mode is using one channel of the amplifier for the left house speakers and the other for the
right. The mixing board channels can be panned left or right according to the position of the instruments on the stage. This
way the house sound can reproduce the stereo “spread” of the instruments.
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 #20 & #21)
with your speakers (SPA-1400C only).
