turned the volume down on or muted the preamplifier or integrated amplifier to which you
have connected your HA-5000
checked that all your connections are snug
•
Turn on the HA-5000 by pressing the button on the front panel of the power supply unit down
to the "on" position.
The running LEDs on the fronts of both the power supply and the pre-preamplifier unit will
illuminate.
The Allnic Audio HA-5000 is now ready for operation.
OPERATION
At this point, if you have not already done it, turn the front panel load selection control knob to
the loading factor that you think will work best for your moving coil cartridge.
The HA-5000 has four input load impedances: 50, 100, 200, and 500 ohms, selectable from a
control on the front panel (see Figure 4). You may need to experiment with different load
settings to find the one best suited for your cartridge.
From this point on, operation is straight-forward. Of course, always be sure you have turned the
volume down to zero or otherwise muted your preamplifier or integrated amplifier before
changing loads with the front panel control.
In the case of any failure, please contact your Allnic Audio dealer.
