Installation and Operation:
Biamping: SPA-1400 – One Amp, Single Cabinet:
One SPA-1400 can be used to separately power the lows and highs of a cabinet with biamp inputs. The MONO/STEREO
SWITCHES
(#16 & #17) must both be in the OUT position. (We show use of channel 1 for the low frequencies and channel 2
for the highs, but you may choose to use 1 for the highs and 2 for the lows.) A separate external electronic crossover must be
added between the mixer and the power amp.
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
®
jack.
