6 Audio signal selection buttons
The function of these buttons depends on the setting of
the audio selection function selector switch as follows.
When the MIXING indicator is lit
To select which input channel is to be recorded on
which channel, press one of the buttons (CH-1 to CH-
4) in the EXT row while holding down one of the
buttons (CH-1 to CH-4) in the REC CH row.
For example, if you press the CH-2 button in the EXT
row while pressing the CH-1 button in the REC CH
row, signals from input channel 2 are recorded on
channel 1.
If you press two buttons in the EXT row
simultaneously, signals from the corresponding two
channels are mixed and recorded on the same channel.
Note
Before selecting signals from two input channels for
mixing and recording in one recorder channel, check to
be sure that the emphasis settings are off for both of
the two input channels. Recording and playback of
mixed signals cannot be carried out correctly if the
emphasis is on for either input channel.
You can check the settings in the channel display
section of the level meters. [EMPH] is displayed for
channels with the emphasis setting on.
The button that was pressed in the REC CH row
remains lit after you have finished making the settings.
When you press the lit button in the REC CH row, the
selected button or buttons in the EXT row light up
again. This allows you to check the settings. To cancel
the settings, press the corresponding button in the REC
CH row while pressing the button for the same channel
in the EXT row.
Adjusting the recording level when the MIXING
indicator is lit
Adjust by rotating the REC knob for the player
channel while viewing the level meter for the recorder
channel.
For example, when recording player channel 1 signals
on recorder channel 2, rotate the CH-1 REC knob
while viewing the level meter for CH-2.
When the INPUT indicator is lit
For each channel, press the button in the SDI row, the
AES/EBU row, or the ANALOG row.
The pressed button lights and the corresponding audio
input signal is selected.
