CoNNeCTING A SubWoofeR
All of the amplifi er pairs (1/2, 3/4 etc..) are identical except for channels 11 and 12. These work double duty as either a stereo pair
or a mono amp to drive a passive subwoofer. When used this way, you have to push the recessed BRIDGE MONO switch inward
and connect your source to the top channel 11 INPUT. This will now step up the output to 120 Watts RMS (200 W peak) for plenty of
bass power! As your subwoofer will likely be a loudspeaker that will solely produce low frequencies, a crossover circuit is not required
in between the source and the bridged amplifi er. When connecting the cable, make sure you connect the speaker using the two
OUTSIDE terminals. You should also increase the wire gauge size to compensate for the extra power as this will reduce the loss due
to heat dissipation in the cable. The minimum subwoofer impedance is 8 ohms.
CoNNeCTING The INPuTS
There are several ways to connect to the CI-1255e from your source system. This can be done with all channels playing the same
music or program material, or be setup with individual programs for each zone. You can also order special modules and mount them
into the OmniPort to add screw-down terminal inputs, Jensen transformer isolation, balanced inputs and even a Dante digital interface
to connect your CI-1255e to an Ethernet network hub.
