OPERATION
POWER SWITCH
The front panel switch is a master or “vacation” power switch. No matter which
turn-on mode you have selected, the master power switch will turn off all cir-
cuitry including the sensing circuitry. If you will not be using the amplifier for an
extended period of time, turn the master power switch “Off” (push button switch
out). When you would like to return to normal operation, turn the switch “On”
(push button switch in).

BICOLOR STATUS LED
The bicolor Status LEDs illuminate “green” when the amplifier circuitry for the
respective channel has been turned on by the Turn-On circuits, and illuminates

USING LEVEL CONTROLS AS LIMITERS
If your system is remote controlled, or if you think that some of the users like
to play the stereo too loudly, you can choose to calibrate the system so that it
is limited to a volume level you assign. The SI-1650 allows you to set different
volume levels for different rooms. Calibrate your system volume levels with the
steps outlined below:
to play the stereo too loudly, you can choose to calibrate the system so that it
is limited to a volume level you assign. The SI-1650 allows you to set different
volume levels for different rooms. Calibrate your system volume levels with the
steps outlined below:
1. Lower all of the SI-1650 level controls to the minimum volume position. If there are
any other amplifiers in the system, lower their level controls to the minimum (all of the
amplifiers in your system must have level controls).
2. Raise all of the individual in-wall volume controls to the loudest setting.
3. Play a loud radio station with the tuner set to Mono.
4. Raise the volume of your preamplifier or receiver slowly– if you hear any sound, lower
the volume again and recheck all of your amplifier levels, they must be at minimum. If
no sound is heard, proceed to step five.
5. Have someone step into each room and listen as you adjust each level control to the
desired maximum level for that room. Adjust the balance between speakers for the
most common listening position in each room.
