Description
THAT 4301 Dynamics Processor, dubbed
crest factors up to 10. One opamp is dedicated
“THAT Analog Engine,” combines in a single IC
as a current-to-voltage converter for the VCA,
all the active circuitry needed to construct a
while the other two may be used for the signal
wide range of dynamics processors. The 4301
path or control voltage processing.

The VCA provides two opposing-polarity, volt-
dynamics processors. This makes it easy to de-
age-sensitive control ports. Dynamic range ex-
sign audio compressors, limiters, gates, ex-
ceeds 115 dB, and THD is typically 0.003% at 0

dB gain. In the 4301A, the VCA is selected for
systems and the like. The high level of integra-
low THD at extremely high levels. The RMS de-
tion ensures excellent temperature tracking be-
tector provides accurate rms-to-dc conversion
tween the VCA and the detector, while
over an 80 dB dynamic range for signals with
minimizing the external parts count.
