3. ANALOG IN/OUT WORD CLOCK INT
48 kHz inspection
3-1. STEREO OUT L/R (XLR)
Parameter
Must be input from CH1(XLR).
q
Distortion ratio (both L/R)
w
Residual noise (both L/R)
Parameter
Switch STEREO OUT Off.
3-2. OMNI OUT 1~4
Parameters
Must be input from CH1 (XLR).
BUS 1~4 ON with CH1 routing.
Assign Bus nCH to OMNI nCH with
an OUTPUT PATCH.
q
Distortion ratio (OMNI OUT 1~4)
w
Residual noise (OMNI OUT 1~4)
Parameter
Switch BUS OUT Off.
3-3. MONITOR OUT L/R
Parameters
Must be input from CH1 (XLR).
Set the MONITOR/2TR lN SW to
MONITOR.
Set the MONITOR OUT LEVEL to
MAX.
q
Distortion ratio (both L/R)
w
Residual noise (both L/R)
Parameter
Switch STEREO OUT Off.
w
f characteristic (CH13~16)
Parameter
The permitted range uses 1 kHz as
the reference.
e
Distortion ratio (CH13~16)
r
Level difference (CH13~16)
The range for the difference in the gain measured
with
q
is regulated as follows.
t
Noise level (CH13~16)
Parameter
Short the CH IN being measured with
150
Ω
.
However, if the permitted range above is not met, EIN
Measurement value (Gain at 1 kHz) must be -102
or more.
B. GAIN MIN
q
Gain (CH13~16)
w
Distortion ratio (CH13~16)
e
Noise level (CH13~16)
Parameter
Short the CH IN being measured with
150
Ω
.
r
Odd channel/even channel crosstalk
Parameters
Input the signals to the odd channels side.
Short the even channel side with 150
Ω
.
The even channels must be the same too.
2-9. CH IN 1~16 level meter operation check
Parameters
Input the regulated level to the
channels being measured (PHONE).
1~16 CH can be input at the same
time.
