adjustable.
You should experiment with the gain settings to find the
best setting for your cartridge. Use identical settings for
both transformers to avoid channel imbalance.
INITIAL POWER-ON
Once you have your H-1201 in place and all connections have
been made to your turntable and preamplifier, you are ready
to turn on the power for your H-1201. Before you power up
the H-1201, though, be sure you have:
removed ALL the cushion materials from inside the tube
chimneys.
turned the volume down or muted your preamplifier
muted the H-1201 by ensuring that the button switch
labeled "mute" on the right hand side of the front panel
of the H-1201 is not "depressed" (i.e., it is "out") (See
Figure 2)
rotated the single knob on the front of the unit, with MM
and MC labels at its top right and left respectively, to the
appropriate input, corresponding to the input you will
use initially, either MC or MM (See Figure 2)
if you are using a moving coil cartridge, set the MC
transformer controls on the top of the chassis to the
factor that you will try initially (See Figure 3)
checked that all your connections are snug
To turn on the H-1201, press in the button switch on the left
front panel. Pressing the power button again will power down
the H-1201 (See Figure 2).
OPERATION
The H-1201 has a "soft start". After pushing in the power
button, the H-1201 will take about 40 seconds to be ready for
play. Each time the H-1201 is powered on, the orange light on
its front panel above the power button will illuminate. If the
"mute button is in the "on" position (button "out" – not
depressed) when you power on the H-1201, the light above
the mute button will illuminate red and stay red after the soft
start period. If the mute button is depressed (mute off), when
you power on the H-1201, the mute light will first glow red,
and after the soft start period will change to orange.
NOTE:
Please mute your H-1201, and/or reduce your preamplifier's
volume control, during transformer gain adjustments. Be aware
if you are increasing gain, that you may hit an uncomfortably
loud volume level.
To avoid surges to the speakers, it is best to switch between the
MM or MC inputs only with the H-1201 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-1201 last
by pressing the power switch on the left side of the unit's front
panel.
In the case of any failure, please contact Hammertone Audio for
assistance.
