toggle HDCD gain adjustment
To toggle between HDCD Auto gain (thereby lowering the volume
of non-HDCD sources by 6 decibels, relative to an HDCD source)
and HDCD Manual gain (requiring you to make appropriate vol-
ume adjustments as you see fit, but avoiding any digital attenua-
tion), enter the setup mode by pressing and holding the
mode but-
ton until the input name for the currently selected input is dis-
played. Then toggle the HDCD setting using the
polarity invert but-
ton. The unit will time out after a few seconds and your change
will be saved for all inputs. (Note: the Nº360S will return to its de-
fault setting of HDCD Auto after a loss of power.)
5 emphasis LED
The compact disc standard, as created by Sony and Philips, allows
a high-frequency boost to be employed during recording. This
boost, called recording pre-emphasis, increases the signal-to-noise
ratio at high frequencies, but must be countered by a high-fre-
quency cut before playback to restore a recording’s normal fre-
quency response. De-emphasis may be done as the recording is
being mastered, or the compact disc (or digital audio tape) may be
made with the pre-emphasis still on, and the de-emphasis per-
formed in the playback unit.
The
emphasis LED lights when the Nº360S detects recording pre-
emphasis in the digital program being processed, and subse-
quently employs its de-emphasis circuitry. In the Nº360S, the de-
emphasis filtering is done in the digital domain.
Note: The de-emphasis circuitry of the Nº360S is designed
to be compatible with all known digital standards.
However, it is possible for the emphasis LED to light
in error when there is no disc being played. This is
not a malfunction of the Nº360S. Rather, it is the re-
sult of the transport generating ambiguous signals in
the absence of a spinning disc to read. You may never
see this condition. Even when the condition exists, it
has no effect on sonic quality, as it can only occur
when there is no disc playing.
6 polarity invert
Pressing this button inverts the polarity of the digital signal, to
compensate for polarity differences during the recording process.
Some recordings may simply “sound better” when this function is
active.
While polarity invert is selected, the LED above the button will light.
