4 BAL (BALANCE)
Pressing this button followed by the
relative volume of the Left and Right speakers. The direction of the
shift is indicated by the green arrowhead indicators in the main
balance
display, and the magnitude of the balance shift is shown in the main dis-
play. Both the volume +/–
their normal operation (volume) after a few seconds.
5 MUTE
Pressing the button will reduce the main output level of the pream-
mute
plifier by a user-modifiable amount, ranging from 1 to 56 decibels (2 to
112 in the main display; the factory default is -20 decibels, which is -40
in the display). Pressing the
the volume will return it to its previous setting. If you adjust the volume
with either the front panel buttons or the remote control while in the
mode, the preamplifier will adjust its volume from the muted vol-
mute
ume and disengage the mute function. By so doing, the PRE avoids sud-
den, unexpected changes in volume. (See Using the PRE for information
on changing the factory default mute setting.)
6 MONO INDICATOR
This indicator LED will illuminate when the PRE is placed into
mode from its remote control. (Hint: set the balance by placing the PRE
into mode and then adjusting the
mono
"center" image to be equidistant between your loudspeakers. This proce-
dure will compensate for small differences in effective speaker sensitivity
and room placement inequalities, yielding the largest possible image
when you return to stereo operation by pressing the mono button on the
remote control again. There is no front panel button for the mono func-
tion.)
7 INVERTED POLARITY INDICATOR
This LED will illuminate to indicate that the
inverted. This inversion is accomplished by pressing the polarity button
on the remote control. Pressing the same button a second time restores
the normal, non-inverting operation of the PRE. There is no front panel
button for this operation, as the distinction is best heard from the listen-
ing position.

prevent the selection of any recordable device as its own
source (to avoid feedback loops). If such a selection is at-
tempted, the PRE will cause the appropriate LED to flash on
the front panel as a warning. The source selected for the
record path is indicated on the front panel in red LEDs.
