t
Odd channel/even channel crosstalk
The even channels must be the same too.
y
Maximum output (OMNI OUT 1~4)
2-4. 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
Gain (both L/R)
w
f characteristic (both L/R)
Parameter The permitted range uses 1 kHz as
the reference.
e
Residual noise (both L/R)
Parameter Switch STEREO OUT Off.
r
L/R level difference
The range for the difference in the gain measured
with
q
is regulated as follows.
t
Crosstalk between left and right
Parameter PAN L swung to cut off.
The right side must be the same.
y
Maximum output (both L/R)
2-5. PHONES OUT L/R
Parameters Must be input from CH1 (XLR).
Set the MONITOR/2TR lN SW to
MONITOR.
Set the PHONES LEVEL to MAX.
