7. REMOTE VOLUME CONTROL CONNECTION
The external volume control can remotely adjust the signal
level at post-master volume control. When performing the
remote volume control, adjust the master volume control in
advance noting that its setting limits the maximum signal level
adjustable with the volume control. Be sure to avoid turning
fully down the master volume control.
Notes
• Negative terminal should not be grounded. Never connect it
to the unit’s chassis nor other circuit ground.
• Only a volume control can be connected to these terminals.
