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.
