Notes
1)
Specifications
are
subject
to
change.
2)
All
voltages
are rms
(root-mean-square).
3)
0
dBv
is
defined
as
0.775
V
regardless
of
load
impedance.
Subtract
2.2
from
the
dBv
figure
to
convert
to
dBV
(i.e.,
referred
to
1 V).
When
the
load
impedance
is
600
ohms,
this
particular
dBv
is
also
known
as
"dBm."

5)
Attack time
is
the
time
required
to
restore
the
signal
to
63%
of
the
input
level
after
it
has
gone
above
the
OverEasy
threshold;
release
time
is
the time
required
for
the
signal
to
be
reduced
to
63%
of
its
final
gated
level.
