to it. The impedance and gain relationships are not user

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.

TUBES

The H-1201 uses the following tubes (See Figure 4):

 Four (4) x NOS E180CC twin triodes

All consequences of changing or attempting to change tubes are

borne by the user unless by express agreement between the

owner and Hammertone Audio. Allnic Audio and Hammertone

Audio are not liable in any way whatsoever for any injury or loss

incurred by the user or for damage to the H-1201, any of its

parts, or tubes or replacement tubes resulting from the user

changing or attempting to change tubes.
