AU voltages
are

3)
0 dBv is defined as 0*773 V regardless of load
impedance. Subtract 2.2
from
the dBv figure to convert to dBV <Ue.j referred to 1 V).
When
the
load impedance is 600 ohms, this particular dBv is also known as "dBrn.**
4) Noise figures are for 20 Hz-20 kHz.
5)
Measured
in the
infinite-compression
region of the dbx OverBasy curve,
attack time
is
the time required to reduce the signal
by
63% of the level
increase above threshold, while release time is the time required to
restore gam
to 90% of the level decrease below threshold.
