the light over the line source button that is depressed will illuminate
•
after about 40 seconds, the light over the "operate" button will illuminate. The L-7000
has a "soft start" delay for the tubes in order to extend tube life.
The Allnic Audio L-7000 is now ready for operation. At this point, you can power on your sources
and, finally, your stereo power amplifier or mono-blocks.
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, it is best to change from input to input only with the "operate"
button set to mute (the light above the button will not be illuminated when the button is in the
"mute" position).
When you are finished listening, turn off your stereo power amplifier or mono-block amplifiers.
Then turn off the L-7000 by depressing the power button on the front panel. The power switch
on the left side panel should stay in the "on" position – this will keep key circuitry warm, and
your L-7000 will be ready to play when the soft-start turns on the L-7000 next time you want to
listen. Turn off your sources last.
CURRENT METERS
These illuminated meters indicate the current supply to the gain tubes in the L-7000. 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-7000 '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 (E810F) 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 tubes (300B or 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.
