For the following channels, the preamp area will show only
the Ø (phase) button:
• Channels to which no input port is patched
• Channels to which a port that has no preamp (such as
an internal port) is patched

OL (Overload) indicator

This will light red when the output of the attenuator exceeds
the OVER Lev setting specified in the METER SETUP popup
(p. 96).
ATT knob

This adjusts the input level of the channel in a range of -48.0
dB– +24.0 dB.
Normally, you should use the preamp gain to adjust the
input level of the channel, and leave the attenuator at 0 dB. It
is convenient to use the attenuator in the following types of
cases:
• When you've patched a port that has no preamp gain,
such as an internal port
• When you've allowed plenty of head margin to avoid
overloading the preamp's AD converter, and want to
boost the level at the channel
