indicators
The function of this switch and these indicators will
change depending on the mode of the M2500.
●
In normal mode
You can use the ON/EDIT switch to turn the monau-
ral input channel on/off. When the channel is
switched on/off, the ON indicator will be lit/dark to
indicate the status. Channels that are switched off will
not send any signals to the GROUP, STEREO,
MONO/C, or AUX buses, but you can still use the
PFL switch (
O
) to monitor the signal from the
MONITOR OUT jacks or the PHONES jack.
●
In check mode
When a scene (which contains the on/off state of the
ON/EDIT switches) is selected, the on/off status
memorized in that scene will be indicated by the lit/
dark status of the CHECK indicator. In check mode,
you can also use the ON/EDIT switch to switch the
CHECK indicator between lit/dark. (The current on/
off setting will not be affected.) For details on check
mode, refer to page 32.

SIGNAL
indicators
These three indicators allow you to check the pre-
fader signal level of the monaural input channel.
•
PEAK
indicator
This will light when the signal exceeds nominal level
by 17 dB.
•
NOM
(nominal) indicator
This will light when the signal reaches nominal level
(0 dB).
•
SIGNAL
indicator
This will light when the signal reaches a level 13 dB
below nominal.
N Channel fader
This adjusts the output level of the monaural input
channel signal. This fader affects the level of the sig-
nal that is sent to the GROUP, STEREO, MONO/C,
and AUX (if the PRE switch is off) buses.
OPFL (pre-fader listen) switch
When this switch is on ( ), the pre-fader signal will
be sent to the MONITOR INPUT PFL bus, and can
be monitored from the MONITOR OUT and
PHONES jacks.
