POWER switch
Press the POWER switch to turn on the unit.

A/D INPUT LEVEL controls
Adjust the level of analog signal input to the A/D
converter.
The control has a variable range of 30 dB,
representing a digital full scale (0 dBFS) at an analog
input level of +24 dBu when it is fully turned
counterclockwise, +14 dBu when set at the center
position, and –6 dBu when fully turned clockwise.
(Graduation of the control excludes a head room of
20 dB.)
A 31-point click level control assures enhanced
reproducibility with any analog input level setting.
3
Level meter and OVER indicator
The level meter indicates a level of A/D or D/A
selected with METER selection switch
4
.
Metered indications are given in dBFS. 0 dBFS
corresponds to a digital full scale.
If the digital full scale lasts for three words or more,
the OVER indicator will light in red.
Note
Using A/D converter, adjust input level controls
2
so that
the OVER indicator will not light even when analog signals
are received at their maximum input level, and also so that
their input level will be maximum.

METER selection switch
Switches the level meter between A/D and D/A to
provide their respective metered indication.

7
DIGITAL INPUT and input selection switch
The central switch selects between AES/EBU input
for pro use and IEC958 input (commonly known as
“S/P DIF”).
A sampling rate converter not only eliminates jitters
that are harmful to sound quality from digital input
but also supports sampling frequencies from 32 kHz
to 48 kHz and word lengths from 16 bits to 24 bits
automatically.
Note
AES/EBU input and IEC958 input cannot be mixed
together.
