**CAUTION: DO NOT TURN ON THE POWER AMPLIFIERS YET.

Consult your speaker and driver manufacturer's specifications for the
recommended crossover frequencies.  Basic setup procedures for the
crossovers are as follows:

• Label each power amplifier for its respective frequency band.

SR834: LOW, MID, or HIGH for stereo operation; LOW, LOW-MID, HIGH-MID,

or HIGH for mono operation. 

SR823: LOW, HIGH for stereo operation or LOW, MID, HIGH for mono

operation.

•  Set each power amplifier volume control at maximum and connect each

power amplifier output to its correct speaker or driver.  

•  Apply power to the crossover.  Apply power to the mixer then the power

amps.

STEREO OPERATION

Using the markings non-italicized markings on the front and rear panels and set
each channel as follows:

•  Set the gain control to 0 dB.  Set all level controls to -12 and switch in the

15Hz high-pass filter if desired.

SR823: Set the LOW/HIGH crossover frequency for each channel according to

the front panel markings.  If below 180Hz is desired, press the ÷10
switch** on the rear panel.

SR834: Set the LOW/MID crossover frequency for each channel according to

the front panel markings.  If below 180Hz is desired, press the ÷10
switch** on the rear panel.  If the desired frequency is below 180 Hz,
the ÷10 switch must be engaged (LED indicator lit).  If the desired
frequency is above 180 Hz, the Range switch must be disengaged
(LED indicator off).  

When the ÷10 switch is engaged, the frequencies marked around the LOW/MID
(LOW/HIGH for SR823) frequency control are divided by 10.  In other words, if
the LOW/MID (LOW/HIGH for SR823) frequency is set at 250Hz and the range
switch is engaged, the actual crossover frequency is 25Hz.

SR834:  Set the MID/HIGH crossover frequency.  The Channel 2 MID/HIGH

frequency control has two sets of markings.  When using the
crossover in stereo mode, use the lower frequency markings to set the
MID/HIGH crossover point.  This frequency control has no range
switch.

WARNING:  BEFORE PRESSING THE ÷10, LF SUM OR STEREO/MONO

SWITCHES, LOWER THE OUTPUTS OF YOUR POWER
AMPLIFIERS TO AVOID DAMAGE TO DRIVERS AND
LOUDSPEAKERS.
