This button toggles polarity inversion of all outputs on and off. This affects
both the left and right channels of the
Main Out
and
Monitor Out
signals.
When the invert mode is off, the signal on Pin 2 is in the normal polarity.
When the invert is on, the signal on Pin 2 is inverted. In balanced mode, Pin 3
is the opposite polarity of Pin 2. In unbalanced mode, Pin 3 is grounded.

This button toggles the signal output to mono when on, and to stereo when
off. This affects both the
Main Out
and
Monitor Out
signals. Loudness
differences between mono and stereo modes vary depending on the degree
of stereo separation of the music.

ALIBRATION
When in calibration mode, the
Rotary Knob
provides fine adjustment to both
Main Out
and
Monitor Out
.
The adjustment range is -0.70 dB to +0.70 dB in 0.1 dB increments. While in this mode, the
Numeric Display
indicates the calibration setting.
Calibration is useful to compensate for minor level differences caused by differences in the input impedances
and input signal range tolerances of driven equipment.

This 4 digit numeric display indicates the Volume level of the
Monitor Out
signals. The minimum level is
“00.00” at which the signal is muted. The maximum level is “80.00”, which is full scale.
When the unit is in calibration mode, this 4 digit numeric display indicates the output calibration setting,
which ranges from -0.70 dB to +0.70 dB in 0.1 dB increments.
The Lavry Quintessence
switches smoothly
between Normal and
Invert, between Mono
and Stereo, and
between Inputs 1, Input
2, and Input 3;
preventing high energy
pops or clicks, from
entering the output
signal.
The Output Enable
buttons are a fast means
to mute the outputs in
case of a corrupted
input signal.
