Connect the outputs of the crossover to the appropriate amplifiers. THE
POWER AMPLIFIERS SHOULD STILL BE UNPOWERED. Check to see that
all crossover level controls are set to -12, and that both gain controls are
set to 0 dB. Apply power to the low frequency amplifier.
Send a broadband signal into the crossover and slowly bring up the LOW
level control. Set the control for the desired level. The gain control can be
used to boost the signal if needed.
SR834: Apply power to the mid frequency amplifier and turn up the MID level
control to the desired level.
SR834/SR823: Finally, apply power to the high frequency power amplifier
and bring up the HIGH level control to the desired level.
Once the output levels are set, any phase problems can be corrected with the
phase inversion switches on the rear panel. THE PHASE INVERSION
SWITCHES ARE MECHANICAL SWITCHES AND SHOULD ONLY BE CHANGED
WHEN THE POWER AMPLIFIER FOR THAT OUTPUT IS OFF. Turning down the
level controls will not prevent transients from appearing at the outputs when
changing the phase switches while the crossover is on. These transients can
damage power amplifiers, speakers, and drivers.
STEREO OPERATION USING A MONO SUBWOOFER
This mode of operation provides:
SR834: Channel 1 and Channel 2 high frequency outputs, Channel 1 and
Channel 2 mid frequency outputs, and one summed low frequency
output.
SR823: Channels 1 and 2 high frequency outputs and one summed low
frequency output.
The setup procedure is the same as for the stereo mode, except that, instead
of connecting both low frequency outputs, connect only the Low Frequency
Sum output to the low frequency amplifier. Set both LOW level controls to the
same level to ensure that both controls contribute the same amount of signal
to the Low Frequency Sum output.
Note:
There is no phase inversion switch on the SR834 for the Low
Frequency Sum output. Any phase problems must be corrected using the
phase inversion switches on the other four outputs.
