8
and moving magnet connections has a number label between the left and right channel input
connections. The “1” pair is to the left of the “2” pair for both MC and MM pairs. These number
labels correspond to the input numbers on the selector knob on the front panel of the phono-stage.
All inputs can be connected at the same time. There are also two screw type, ground connection
pins, one to the left and one to the right of the two sets of MC and MM input connections. Both
ground connections can be connected at the same time.
When you are facing the front of the H-5000, the two pairs of MC connections are on the right of
the unit, with the two MM connections immediately to their left.
To select the input you want to play, MC1 or MC2 or MM1 or MM2, use the MM or MC and Input 1
or 2 buttons on the right hand side of the face of the phono-stage (See Figure 1). The left button
selects MM and MC. MM is selected when the button is in the down position. MC is selected when
the button is up. The right button selects input 1 or 2 for whichever cartridge type you have chosen.
Input 1 for the cartridge type is selected when the Input button is in the down position. Input 2 for
the cartridge type is selected when the Input button is up.

OUTPUTS
The H-5000 is equipped with one pair of unbalanced or “single-ended” (RCA) outputs and one pair
of true balanced (XLR) output connections. Each output pair is oriented vertically, with the left
channel output connectors above the right channel output connectors. The left channel output
connectors are labeled “L”, and the right channel output connectors are labeled “R” (See Figure 2).
Each pair of output connections is numbered. The unbalanced (RCA) output connections are labeled
“1”, and the balanced (XLR) connections are labeled “2”.
Immediately to the right of the two pairs of output connections is a switch for selecting either the
balanced or the single-ended output connectors. The switch is labeled to indicate that the upper
position is for the balanced (XLR) output connectors, with the lower position being for the
unbalanced (RCA) output connectors. You may have both balanced and unbalanced outputs
connected at the same time without introducing hum PROVIDED you have the output switch set to
unbalanced output.

MOVING COILS (MC) TRANSFORMER CONTROLS
On the top of each channel’s MC transformer, located on the left rear of the chassis deck of
the phono-stage unit (right left corner if you are facing the front of the unit), there is a rotating
control (see Figure 3). Turn the control knobs to select from four gain factors: +22dB, +26dB,
+28dB and +32dB (x 13, x 20, x 26 and x 40). The four control positions are labeled as both gain
and the turn ratio of the MC transformer; for example, the lowest gain position of +22dB
automatically corresponds to a turn ratio of x13. You should use identical settings for both
transformers to avoid channel imbalance.
NOTE:
Please mute your H-5000, 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.
