Signal detector sensitivity
The LK85/140 uses signal sense circuitry to detect the presence of an audio input signal. As soon as the amplifier detects the presence of an audio signal, it will power up and a small indicator light adjacent to the power switch will light green. Whenever an audio signal is removed, the amplifier powers down to standby mode after a short delay until it again detects an audio signal. The small indicator light will turn red when the amplifier switches to standby mode.
Adjusting the signal detector
The LK85/140 is shipped with signal sense circuity set to maximum sensitivity for normal operation. However, if you find that interference or other audio noises in your system cause the amplifier to power up, you may wish to decrease the sensitivity of the signal detector. To do this turn the signal detector sensitivity control on the back panel anticlockwise towards the minimum position.
