Connecting the speakers
The LK240 comes equipped with four pairs of speaker output
sockets to allow bi-wiring, or even tri-wiring. Alternatively, auxiliary
speakers may be connected.
The type of speaker socket on your LK240 will depend on the
market it was manufactured for. If European, the socket will be a
high contact pressure binding post suitable for connecting with
bare speaker wire. If American, the socket will be suitable for
banana type connectors.
Operation
To turn on the LK240 amplifier, press the power switch on the front
panel.
Signal detector sensitivity
The LK240 uses signal sense circuitry to detect the presence of an
audio input signal. As soon as the LK240 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 LK240 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 LK240 switches to standby mode.
Adjusting the signal detector
The LK240 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 LK240
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.
