SETUP

**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.
