Bridge Mode Hi-Z (140V/200V)
Typical input and output wiring, along with Attenuator and Mode DIP Switch settings are shown in Figure 9. Make sure the “Hi-Z” selector switch for the connected input
channel is in the ON (up) position and the Bridge (BRG) switch for the channel pair also is in the ON (up) position. A 35Hz high pass filter is selected automatically when
the amplifier channel is in Hi-Z or Bridged Hi-Z mode. The filter can be changed to 70Hz, please contact your local Crown service center for detailed instruction for this
modification. NOTE: Only the Hi-Z selector switches assigned to odd-numbered channels (1,3,5,7) are active in Bridge mode; switches assigned to even-numbered channels
(2,4,6,8) are disabled.
INPUTS: Connect the input to the odd-numbered channels (1,3,5,7) only. Even-numbered inputs are disabled when the Bridge DIP Switch is ON.
OUTPUTS: Connect the speaker across the positive terminals of each channel pair. Do not use the negative terminals of the channel pair when the pair is being operated in
Bridge-Mono mode.
NOTE: For global selection of 70V (140V bridged) or 100V (200V bridged) operation, refer to Page 14.
