Installation and Operation:
Biamping: SPA-1400 – One Amp, Separate Cabinets:
One SPA-1400 can be used to power separate low and high frequency cabinets. 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 ® jacks.
