transformer in the H-1200 can accept cartridges with up
to 300 ohms internal impedance.
INITIAL POWER-ON
PLEASE NOTE – CAUTION!
Be sure you have turned the volume down or otherwise
muted your preamplifier before turning on the H-1200.
Also, make sure all your connections are snug.
1) Once you have your H-1200 in place, all
connections have been made to your turntable
and preamplifier, the MC (for moving coil, top
position) / MM (for MM, bottom position) switch
on the face H-1200 to the appropriate position
(Please refer to Figure 2).
2) Move the switch marked with the vertical line
above it and the circle below it (this is the power
switch to the "on" position – that means the
switch is pushed up toward the vertical line. Of
course, the off position is the reverse, moving the
switch down toward the circle below it.
OPERATION
When the Allnic Audio H-1200 has powered up, the light
above the word "ALLNIC" will illuminate.
The Allnic Audio H-1200 is now ready for operation.
To avoid surges to the speakers, it is best to change from
MM or MC input to the other only with your preamplifier
volume down or otherwise muted.
From this point on, operation is straight-forward. Of
course, always 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 CD's.
When you are finished listening, turn off your power
amplifier(s); then turn off your preamplifier and then the
H-1200 last.
In the case of any failure, please contact Hammertone
Audio for assistance.
