Noise Gate
The ADX-100 Noise Gate with variable threshold level is
extremely effective in reducing background hiss and noise
during portions of a program with no signal. The ADX-100 also
has unique High-Pass/Low-Pass key filters, comprehensive
envelope control, and ultra-fast attack time. The gate works by
muting the corresponding channel when no signal is present, or
when the signal level falls below the gate threshold detection
level. Normally the gate level will be set below the lowest
program level so that it will pass all program material.
