Using Level Controls as Limiters
Using the individual level controls, the SI-1260 enables you to set a specific volume
level for each of the different rooms connected. Individual room volume levels can
be calibrated so that all rooms have similar volume control characteristics regardless
of size and acoustics and to establish a maximum volume level. This is especially
useful if your system is remote controlled, or if some of the users like to play the
stereo too loudly.
Calibrate your system’s volume levels using the steps outlined below:
1. Adjust all of the SI-1260’s level controls to the minimum volume position. If there
are any other amplifiers in the system, adjust their level controls to the minimum.
(All of the amplifiers in your system must have level controls).
2. Adjust all individual in-wall volume controls to the loudest setting (fully clockwise).
3. Play a loud radio station.
4. Increase the preamplifier or receiver’s volume up slowly. If you hear any sound,
lower the preamplifier’s volume again and recheck all amplifier levels, they must
be at minimum. If no sound is heard when the preamplifier is turned all the way
up, proceed to step five.
5. Have someone step into each room and listen as you adjust each level control on
the SI-1260 to the desired maximum level for that room.
6. Adjust the volume for each channel to achieve a good balance from the most used
listening position in each room.
