Step 5

Operating the amplifier

As soon as a valid transmitter signal is received by the amplifier, the amplifier

will output the amplified audio signal to the speaker outputs. You can change

the audio level by adjusting the amplifier volume control.

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

amplifier.

2) Set your audio source to output the maximum audio level that you will

encounter during normal operation.

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 the amplifier volume control to a setting that yields the desired volume

from the speakers.

If no audio signal is received for more than 2 minutes, the amplifier will go into

standby mode (power-down mode).
