INPUTS

There are two (2) pairs of single-ended (RCA) inputs, one for Moving Coil (MC) cartridges and the other for Moving

Magnet (MM) cartridges. These two pairs are located in the middle of the rear of the H-1202 (See Figure 1) and

labeled "MC – input – MM" between the top and bottom connectors. Facing the rear of the H-1202, the left hand

pair of inputs is the moving coil cartridge input; the right is for moving magnet cartridges. Each pair of inputs is

aligned vertically, with the left channel "left" labeled input at the top and the "right" labeled input on the bottom.

To the left and right (facing the rear panel) of the MC and MM input connections respectively is a screw type

ground connector. Either or both of these may be used for multiple ground connections.

When you are facing the front of the H-1202, the input connections are in the centre of the unit, with the MC

connections on the right and the MM connections immediately to their left.

The H-1202 has been designed and manufactured to work most synergistically with Allnic Audio products, including

line-stage preamplifiers, pre-phono stages and ZL Technology cable products.

OUTPUTS

The H-1202 is equipped with one set of unbalanced or "single-ended" (RCA) outputs. The output connection is just

to the left (facing the rear panel) of the AC IEC power cord connection. The left channel output connection is the top

one and is labeled "left"; the bottom, "right" (See Figure 1).

On the top of each channel's MC transformer on the centre rear of the chassis deck of the H-1202 (See Figure 4),

there is a rotating control (See Figure 3). Turn the control knob to select from four gain factors: +22dB, +26dB,

+28dB and +32dB. Combined with the H1202's 40dB native gain, for MC there is 62dB, 66dB, 68dB and 72dB of

gain available. Each of the second set of indicators on the top of the transformers only marks the impedance tied

to the gain setting diagonal to it. The impedance at each of ×13, ×20, ×26 and ×40 on the control knob is equivalent

to 29Ω, 69Ω, 117Ω and 278Ω respectively. 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-1202 in place and all connections have been made to your turntable and preamplifier, you are

ready to turn on the power for your H-1202. Before you power up the H-1202, 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-1202 by ensuring that the button switch labeled "mute" on the right hand side of the front panel of

the H-1202 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
