INPUTS

In the centre of the four RCA connections on the rear of

the AUT 2000's chassis is a screw type connector. This

connector is the ground connection for a ground wire

from a cartridge and/or turntable. Please refer to Figure

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 AUT

2000'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 AUT 2000's rear panel (on the right

if you are facing the front of the unit).

OUTPUTS

The AUT 2000 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 AUT 2000'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 AUT 200's

rear panel (on the right if you are facing the front of the

unit).

The AUT 2000 has been designed and manufactured to

work most synergistically with other Allnic Audio

products, for example the Allnic phono stages and

preamplifiers.

OPERATION

Be sure you have turned the volume down or otherwise

muted your preamplifier before connecting the AUT

2000. Also, make sure all your connections are snug.

At this point, if you have not already done it, using a coin

or other non-abrasive suitably shaped object to turn the

two front panel gain selection switches to the gain that

you think will work for your moving coil cartridge.

The "X#" scale on the rotating selectors corresponds to

the factor that you will select for the millivolt output of

your selected MC cartridge. Each position on the X#

scale corresponds to an increase in gain, indicated on

the +#dB scale. You should use identical settings for

both transformers to avoid channel imbalance.

The possible settings are:

10 X / +22dB Gain

•

15 X / +26dB Gain

•

20 X / +28dB gain

•

30 X / +32dB Gain

Please see Figure 5. You may need to experiment with

different gain 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

or otherwise muted your preamplifier before changing

gain on the front panel selectors.

Also, BE CAREFUL about differences in gain between your

sources. Generally, disc players and tuners will have

greater gain than phono stages, with or without step-up

transformers. That means the volume setting for listening

to your turntable might be too high for listening to CD's.

In the case of any failure, please contact Hammertone

Audio.
