3. Access the PAN/ROUTING function M/S screen.
4. Click the M/S DECODE ON/OFF button for the
corresponding two channels, to turn the button on.
With this setting, the odd-numbered (L) channel will
input the (M+S) signal, and the even-numbered (R)
channel will input the (M–S) signal (the M signal
summed with the inverted-phase S signal).
Even if only one signal (the M signal or S signal)
is patched to an input channel, turning M/S
DECODE on will send the signal to both chan-
nels.
5. Move the cursor to the S-GAIN knob, and turn the
[DATA] encoder to adjust the level of the S mic rela-
tive to the M mic.
At the MONO position, S = –infinity. At the STE-
REO position, M = S. At the EXP.ST position, S =
+10 dB.
M/S decoding is performed immediately after DE-
EMPHASIS and immediately before ATT. (attenua-
tor).
For this reason, please note that when M/S decod-
ing is on, the following meters will show the signal
level before M/S decoding.
•
The input unit meter displayed in the HA/INSERT
function screen
•
The screen/panel meters when the METER function
METERING POINT setting is set to PRE ATT.
•
The input unit meter displayed in the INPUT UNIT
screen (SYS/W.CLOCK function)
A headroom margin of approximately 18 dB is
maintained before M/S decoding. If the signal clips
while you are using M/S decoding, you can use the
attenuator to lower the level and input an
unclipped signal if the clipping is below the head-
room margin.
Since M/S decoding is a special function, it cannot
be copied between channels or saved in a channel
library. Also, the RESET BOTH button in the
CHANNEL PAIRING popup window will not be
valid.
