T21 Audio Processor Options
Compressor Mode:
The audio processer in the T21 is capable of
three modes of operation. The standard
setting provides compression as shown.
Compression is used for hearing assistance
to limit the dynamic range of the audio
signals. Hearing impaired people generally
have a reduced tolerance for wide
dynamic range.
Noise Reduction Mode:
The T21 can also be configured for for 2:1
compression. This is for use only with a
receiver that has a 2:1 expansion circuit for
noise reduction. Noise reduction is typically
used in narrow-band operation for high
quality audio.
Soft-Limit Mode:
The T21 can also operate in a soft-limit
mode, which allows full dynamic range of
audio signals. This mode may be preferred
for musical programs, but may provide too
much dynamic range for hearing impaired
listeners.
For assistance in selecting an alternate
audio processing mode, contact Williams
