Step5Operating 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.
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.
If no audio signal is received for more than 2 minutes, the amplifiers will go into standby mode
