CUT/BOOST: ON -20 DB
DC REMOVAL ON +POLARITY
Cut/Boost:
The signal level can be adjusted over a range of +60 dB to -60 dB in 1 dB steps. The function
can be turned on and off without changing the amplitude change value.
DC offset removal:
Removes any DC offset in the signal. DC removal should be activated prior to
processing of audio, to allow for some settling time (less then 3 seconds) and to avoid a "click" sound. The
algorithm continues to monitor and correct for slow varying offset variations.
Polarity:
+POLARITY
corresponds to analog input signal connection with "pin 2 hot".
-POLARITY
corresponds to analog input signal connection with "pin 3 hot";
-POLARITY
inverts the phase of the signal
by 180˚.

FINE:OFF 20 METER: -00 H
OUT: NO-EMPH DISPLAY:3
FINE: OFF 20 / BIT
This screen is used to select the BIT display mode and the FINE mode with its corresponding reference
point from -10 dB to -20 dB. In FINE mode, the reference LED will be lit, and the channel level will be
displayed in increments of 0.2 dB around that reference point. This is useful for setting precise levels.
Indications are OFF, ON, and BIT. The BIT mode displays the active bits in the output stream, with the
most significant bit displayed to the right (0 dB LED). This display shows active bits in the data.
METER: -00
(Meter Range)
Normal display showing peak and peak-hold indicates levels ranging from 0 to -55dB. While such a setting
is useful in normal day to day operation, extending the display to indicate lower level activity allows
monitoring low levels.
