operating modes is given by the Mode Indicators below the
Alphanumeric Display. (See 3, above.)
5 INVERTED POLARITY INDICATOR
The polarity (sometimes inaccurately called “absolute phase”) of
the output of the Nº38 may be inverted via the Nº38 remote
control, in which case this LED will light as confirmation. A second
press of the Polarity button on the remote control will restore the
polarity of the output to its original, non-inverted state.
6 OUTPUT LEVEL
This control is normally used to adjust the listening volume, and
does not effect the level of the signal being sent to the Record
Outputs. When in Balance Mode, this knob is used to vary the
relative output of the Left and Right channels. It is also used during
set-up for various adjustments; see “Set-up and Installation.”
7 MONO BUTTON
This button toggles between Stereo and Mono operation. When in
Mono, it activates circuitry which combines Left and Right input
signals, and sends the resulting monophonic signal to
both Left
and Right outputs. This circuit is particularly useful when listening to
older, monophonic source material, at which time significant noise
reduction may be realized.
8 SOURCE SELECTOR BUTTONS
Inputs 1–6 are selected by pressing their respective buttons. When
in the Monitor Mode, pressing one of these buttons will select the
source to be heard (
i.e., sent to the main outputs); when in Record
Select Mode, pressing one of these buttons will select the source to
be recorded (
i.e., sent to the record outputs).
9 MUTE BUTTON
Pressing the Mute button will reduce the main output level of the
preamplifier by a user-modifiable amount, ranging from 1 to 60
decibels. 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 output control knob or the remote control
while in the Mute mode, the preamplifier will adjust its volume
from
the muted volume and disengage the Mute function. The factory
default setting of the Mute circuit is -20 dB. (See “Set-up and
Installation” for information on changing the factory default
setting.)
10 STANDBY BUTTON
Toggles the Nº38 between normal operation and Standby, wherein
the display is turned off, the outputs are disconnected, and all
controls are inoperable. All critical circuitry remains powered-up
during Standby to ensure immediate, optimal performance when
you are ready to listen to music. The LED above the Standby
button will blink slowly when the Nº38 is in Standby, indicating that
power is still being provided to the unit. (If the Nº38 is Linked to
other Mark Levinson components which are also in Standby, they
will blink in unison.)
