MODE INDICATORS
Three LEDs give visual confirmation of the operational 

the Nº380S is

in at any moment. When the 

control of the Nº380S is “off-center,”

the 

remains lit as a reminder, in addition to other 

that might be on to indicate either 

or 

.

MODE BUTTON
Cycles among the three primary operational 

of the Nº380S: 

(the source being listened to); 

(the source being provided to

the Record Outputs); and 

(the relative volumes of the Left and

Right channels). Confirmation of these operating modes is given by the

below the 

.  (See 3, above.)

INVERTED POLARITY INDICATOR
The 

(sometimes inaccurately called “absolute phase”) of the output

of the Nº380S may be inverted via the Nº380S remote control, in which
case this LED will light as confirmation. A second press of the 

but-

ton on the remote control will restore the polarity of the output to its origi-
nal, non-inverted state.

VOLUME KNOB
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

mode, this knob is used to vary the relative output of the Left and

Right channels. It is also used during setup for various adjustments; see
“Setup and Installation.”

MONO  BUTTON
This button toggles between 

and 

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,
since significant noise reduction is often realized by listening to mono re-
cordings in mono.

SOURCE SELECTOR BUTTONS
Inputs 1–6 are selected by pressing their respective buttons. When in the

mode, pressing one of these buttons will select the source to be

heard (i.e., sent to the main outputs); when in 

select mode, pressing

one of these buttons will select the source to be recorded (i.e., sent to the
record outputs).

MUTE BUTTON
Pressing the 

button will reduce the main output level of the preampli-

fier 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.
