OPERATION
From this point on, operation is straight-forward. All functions are controlled from the front
panel or the remote control. Of course, BE CAREFUL about differences in gain between your
sources. Generally, disc players and tuners will have greater gain than phono stages. That means
the volume setting for listening to your turntable might be too high for listening to CDs or
streaming devices.
To avoid surges to the speakers when using the Selector knob or remote control to switch
inputs, it is best to do so with the volume turned all the way down or the unit muted from the
remote control (the "operate" light will not be illuminated when the L-6500 is muted).
When you are finished listening, turn off your stereo power amplifier or monoblock amplifiers.
Then turn off the L-6500 by depressing the power button on the front panel or the remote
control. Turn off your sources last.
CURRENT METERS
These illuminated meters indicate the current supply to the gain tubes in the L-6500. They are
indicators of failure or damage to the function of the unit. There is one meter for each channel.
The needle should be between the two parallel lines just left of centre on the meter face. Any
failure of the tubes or circuits in one or the other of the L-6500 's channels is indicated by the
needle on the meter for the respective channel moving out from between those two parallel
lines.
•
If the needle has moved to the left of the parallel lines on a meter, it means that the gain
tube (5842) for that channel is failing.
•
If the needle on either meter moves to the right of the parallel lines, it means that one, or
both, of the voltage regulator/error detector tubes (7233 and 5654) for that channel is
failing.
In the case of any failure indicated by the meter, please contact Allnic Audio or its authorized
representative for assistance.

All consequences of changing or attempting to change tubes are borne by the user unless by
