Adjusting the Input
Once the audio level from the central music
system is configured:
1. Disconnect / turn off the power source to the
LCAi220.
2. Set the device used for the local source to
variable output.
3. Turn the input level on the LCAi220 to minimum,
all of the way counter-clockwise. (Figure #1)
4. Reconnect / turn on the power source of the
LCAi220.
5. Turn on the local source device. Adjust the
volume on the source device to approximately
80% of total output. Slowly turn up (clockwise)
the input level control on the LCAi220. (Figure
#2) The local LED will illuminate once a source is
detected. Continue to turn up the desired maxi-
mum level is achieved.
6. If a subwoofer is connected to the LCAi220,
adjust the subwoofer gain so it is balanced with
the main speakers.
