STANDBY
Provided the Nº30.5 is connected to AC power (via the PLS-330), pressing
this button takes the Nº30.5 out of “standby” mode, turns the
display
on,
and enables the front-panel controls.
Pressing
standby
again places the Nº30.5 into standby mode, turns the
dis-
play
off, turns off all outputs (including the record outputs), and disables
the front-panel controls.

STANDBY LED
While the Nº30.5 is in standby mode, this LED flashes approximately every
five seconds. When the Nº30.5 is ready to operate (that is, when it is not in
standby mode), this LED remains lighted.

SOURCE SELECTION BUTTONS
Pressing these buttons selects the digital source, according to the input con-
nections on the rear panel (see “Rear panel, Nº30.5”). Only one source at a
time may be selected.
When power is first applied to the Nº30.5 (or when power is restored after
an interruption), it will search for and select the first input with an active
digital signal. If none is found, it will select the first named source. As deliv-
ered from the factory, this input will be “AUX1.”
When the Nº30.5 is taken out of standby mode, the source last selected be-
fore going into
standby
will be automatically selected.
