Meters
•
Moving
coil[MC)
meter
is
factory
calibrated
to
OVU
= +4dBu
with
1kHz sinewave. With the
VU
Cal
button
pressed, the
meter
can
be
adjusted
on
the
rear
panel to
allow
OVU
to
equal+
10dBu to +26dBu
with
the
centre
detent being
equal
to +22dBu
• Peak
LED
meters
calibrated
in the
detent
position
for
OdBFS = +22dBu,
calibration
is
adjustable
on the
rear
panel to
allow
OdBFS
to equal +10dBu to +26d8u
Routing
for
MC
and Peak1
meter
is
after
the
HPF,
pre
insert
send
or
switched
post
insert
return.
Peak2
is always pre
ADC
channel2,
which
can
be
fed by
external
input
or
Instrument
input.
LED
levels
are as
follows
when
peak
calibration
is set to
center
detent
on
the
rear
panel. [This is
when
using the
internal
ADC).
