Operating the amplifiers
As soon as a valid transmitter signal is received by the amplifiers, the amplifiers
will output the amplified audio signal to the speaker outputs. The amplfier marked
“LEFT” will output the left audio channel and the amplifier marked “RIGHT” will
output the right channel. You can change the audio level by adjusting each
amplifier volume control.
If no audio signal is received for more than 2 minutes, the amplifiers will go into
standby mode (power-down mode).
In order to achieve maximum transmission quality, the transmitter volume control
should be set to match the audio level of your audio source as follows:
1) Set the amplifier volume control to a low level to prevent clipping inside the
amplifiers.
2) Set your audio source to output the maximum audio level that you will
encounter during normal operation such that both the left and right channel are
balanced.
3) Turn the transmitter level control knob to the position that yields maximum
audio loudness to the speakers without any clipping (distortion). If the
transmitter level is set too low, the dynamics of the transmission are not fully
used. If the level is set too high, audio clipping (distortion) will occur inside
the transmitter.
4) Turn each amplifier volume control to a setting that yields the desired volume
from the speakers such that the volume at both speakers is balanced.
