Information
The
Symetrix 421 is a wide-range AGC-Leveler, a peak
limiter, and a downward expander. The 421 reduces the
dynamic range of its input signal by the amount of its ratio
setting. That is, if the ratio setting is 2:1, then 40 dB of
input range turns into 20 dB at the output. A fast peak
limiter puts an absolute ceiling on the output level so you
know that peaks are held to the level that you set. A
downward expander reduces the gain when signal levels fall
too low to process, reducing the noise buildup at low signal
levels. Speech filters allow reducing the bandpass of the
421 to minimize feedback or amplifier power waste caused by
spurious out-of-band signals.
AGC-Levelers can be used anywhere that you might need to
reduce the dynamic range of an audio signal over a wide
range of signal levels. Possible applications include: tape
duplication (especially cassette), driving telephone lines,
driving broadcast or STL transmitters, podium or lectern
microphones,paging systems, unattended sound systems, and
music recording.
The 421 is Listed by Underwriters Laboratories Inc. (UL).
Samples of this product have been evaluated by UL and meet
