Connecting the speakers
The LK85/140 comes equipped with two pairs of speaker output
sockets to allow bi-wiring. Alternatively, auxiliary speakers may be
connected.
Operation
To turn on the LK85/140 amplifier, press the power switch on the
front panel.
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.
