Basic setup procedures for the
� 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.
