Added functions

The following functions have been added with

2  GANG function

MS microphone decoding 

mode

Setting the MS decoding mode 

Select the 

MS MODE

 item on the 

SYSTEM

 menu to 

open the 

MS MODE

 screen. 

Set the decoding mode to use when connecting mid-

side microphones. Channel pairs 1-2, 3-4 and 5-6 can 

each be set separately.

OFF (default value)

Recording and playback use the ordinary mode

(no mid-side decoding).

INPUT

Use this mode to decode while recording.

Playback uses the ordinary mode.

MONITOR 

Use to monitor the output of mid-side 

microphones

with decoding while recording 

without decoding.

Also use this with a take that was recorded 

without decoding to decode it during playback. 

In that case, 

A.OUT SEL

 should be set to 

MIX

 in 

the 

I/O

 menu.

NOTE

The 

MS MODE

 screen settings cannot be changed 

during recording or playback. Always stop the unit 

(the transport icon should be  ) before changing the 

settings.

Connecting a mid-side microphone

When using this unit's mid-side decoding function, 

connect the mid signal to the odd channel and the 

side signal to the even channel in the pair. If you 

connect them in reverse, correct decoding is not 

possible.

For example, connect the mid signal to channel 3 

and the side signal to channel 4. 

Recording with mid-side decoding

1  On the 

MS MODE

 screen, set the decoding 

mode to 

INPUT

. 

2  Press the MIX PAN key on the front panel to 

open the 

PAN

 screen (pan pot adjustment 

screen). Use the MS width control to adjust the 

width of the mid-side signal pair. 

  Press one of the number (1-6) keys on the front 

panel that corresponds to one of the mid-

side channels that was set to 

INPUT

 on the 

MS MODE

 screen. (For example, press 3 or 4 to 

adjust paired channels 3 and 4.)

  Use the VALUE dial to adjust the width of the 

signal suitably in a 0–100 range. At 0, only the 

mid channel is included in the stereo decoding. 

As the value is increased, more of the side 

channel is included in the stereo decoding. At 

100, only the side channel is included. (The 

default value is 

0

.) 

3  Press the MIX LEVEL key on the front panel 

to open the 

LEVEL

 screen, and adjust the 

decoder output. 

  Press one of the number (1-6) keys on the front 

panel that corresponds to one of the mid-

side channels that was set to 

INPUT

 on the 

MS MODE

 screen. (For example, press 3 or 4 to 

adjust paired channels 3 and 4.)
