Each channel of the ICS
™
4200 can drive conventional low-impedance loudspeaker loads (≥4 Ohms) or
a 70 Volt constant-voltage audio distribution system directly. The setting of the output selector
switches determines the mode for each pair of outputs. One switch controls Channels A and B and
the other switch controls Channels C and D. Single channel selection is not possible. For proper cable
selection‚ see Wire Gauge Chart on page 5 of this manual.
LLooww ZZ
This mode allows each output of the channel pair to drive a 4 or 8 Ohm loudspeaker load. Use the
Bridged Mode to deliver the power of both channels to a single 8 Ohm load such as a subwoofer. Se
INPUT MODES above.
7700 VV
This mode allows each output of the channel pair to directly drive a 70 Volt constant-voltage audio
distribution system. Use the Bridged Mode to deliver the power of both channels to a 140 Volt
constant-voltage audio distribution system. See INPUT MODES above.
