4 BAL (BALANCE)
Pressing this button followed by the volume +/– buttons will alter the
relative volume of the Left and Right speakers. The direction of the
balance shift is indicated by the green arrowhead indicators in the main
display, and the magnitude of the balance shift is shown in the main dis-
play. Both the volume +/– buttons and the main display will revert to
their normal operation (volume) after a few seconds.
5 MUTE
Pressing the
mute button will reduce the main output level of the pream-
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 mute button a second time without adjusting
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
mute mode, the preamplifier will adjust its volume from the muted vol-
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 mono
mode from its remote control. (Hint: set the balance by placing the PRE
into mono mode and then adjusting the balance to place the resultant
“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 polarity of the PRE has been
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.
8 PATH SELECTOR
Pressing this button cycles among your various signal path options:
• main — this path determines which audio sources are sent to
the main outputs on the back of the PRE. Sources selected for
the main path are indicated in yellow on the front panel
LEDs.
• record — determines which audio sources are sent to the
PRE’s record output jacks. As a safety measure, the PRE will
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.
