pressed the button switches on the right
hand side of the front panel of the phono
stage to the appropriate positions for the
cartridge type, either MC or MM, and the
input ("1" or "2") that you will use initially
(See Figure 3). The left of the two button
switches is for choosing MM (button
pressed in) or MC (button out). The button
switch on the right is to choose the input
for that type of cartridge, either MM or
MC. The position for input 1 is with the
button pressed down in the low position,
and the position for input 2 is with the
button pushed to return to the raised
position.

OPERATION
When the power supply is on, the light on its front
panel will illuminate, and the light above the word
"ALLNIC" on the front panel of the Allnic Audio H‐
1500 II PLUS phono stage will illuminate.
After a forty (40) second automatic protective
"mute" period, the Allnic Audio H‐1500 II PLUS will
be ready for operation.
To avoid surges to the speakers, it is best to switch
between MM or MC input, or between inputs 1 and
2 of either, only with the H‐1500 II PLUS in "mute"
mode and with your preamplifier volume down or
otherwise muted.
From this point on, operation is straight‐forward. All
functions except for MC transformers' gain selection
are controlled from the front panel. 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 CD's.
When you are finished listening, turn off your power
amplifier(s); then turn off your preamplifier and then turn
off the H‐1500 II PLUS last by pressing the on‐off switch on
the front panel of the power supply so it returns to the
out position.
In the case of any failure, please contact Hammertone
Audio for assistance.
