Selecting ADAT Sample Rate:
As ADAT double sample rate format is not detected
automatically, you must select this manually if required.
Press and hold the ADAT button for approximately 3
seconds to select double sample rate (88.2 or 96 kHz).
When double sample rate is selected, the yellow “x2”
LED is lit.
5 – CLOCK STATUS LEDs
The CLOCK STATUS LEDs indicate the sample rate of
the currently selected input. When the yellow “x2” LED
(double sample rate) is lit, the “44.1” LED represents
88.2 kHz and the 48 LED represents 96 kHz.
6 – REF Button
Calibrated level listening makes it easy to move from
studio to studio, avoiding accidental “squashing” of the
mix in a misguided search for extra loudness.
Furthermore, Calibration makes the spectral balance of
a mix more predictable (because we aim at different
spectral targets when reproduction level changes).
Calibration is typically performed using pink noise at a
defined level, e.g. -20 dBFS RMS. With an SPL meter
reading slow C weighted, set the level at your listening
position to a certain SPL per speaker. Typical values
would be between 70 and 85 dB SPL, depending on
the application.
The REF button removes the Rotary Control <1> from
the speaker signal-path, and assigns a preset gain
(SPL calibrated speakers) to the analog speakers and
the speakers assigned to ALT.
When you press REF, the meters momentarily show
the preset gain assigned to speakers (L) and
headphones (R) before resuming normal operation.
To calibrate analog speakers and headphones:
–
With REF disengaged (LED unlit), set the desired
level using the Rotary knob and the headphone
level control.
