There is one (1) pair of single-ended (RCA) inputs. The right
and left channel input connections are the bottom pair of
RCA connections, below and to the left and right of the
ground connection. The left channel input connection is on
the right of the unit, facing the HA-5000’s rear panel (on the
left if you are facing the front of the unit). The right channel
input connection is on the left of the unit, facing the HA-
5000’s rear panel (on the right if you are facing the front of
the unit).

OUTPUTS
The HA-5000 is equipped with one pair of single-ended (RCA)
outputs. The right and left channel output connections are
the top pair of RCA connections, above and to the left and
right of the ground connection. The left channel output
connection is on the right of the unit, facing the HA-5000’s
rear panel (on the left if you are facing the front of the unit).
The right channel output connection is on the left of the unit,
facing the HA-5000’s rear panel (on the right if you are
facing the front of the unit).
Power
Be sure the HA-5000 power supply power button switch is
in the “off” position (“out”- not depressed) before
connecting the IEC equipped power cord to the rear of the
power supply. The HA-5000 power supply unit uses a
standard IEC AC connection. The DC umbilical cable to the
pre-preamplifier unit is fixed to the rear of the power supply
and connects to the rear of the pre-preamplifier unit. The
umbilical cable must be inserted snugly into the connector
on the rear of the prepreamplifier unit and then secured,
using the screw collar around the connector.
OPERATION
Be sure you have turned the volume down or otherwise
muted your preamplifier before connecting the HA-5000.
Also, make sure all your connections are snug.
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 for your moving coil cartridge.
The HA-5000 has four input load impedances: 50, 100, 200,
and 800 ohms, selectable from a control on the front panel.
You may need to experiment with different load
settings to find the one best suited for your cartridge.
Turn on the HA-5000 by pressing down the button on the
front panel of the power supply unit to the “on” position.
The running LED on the front of the pre-preamplifier unit
will illuminate.
From this point on, operation is straight-forward. Of
course, always be sure you have turned the volume down
or otherwise muted your preamplifier before changing
loads with the front panel control.
In the case of any failure, please contact Allnic Audio.
