❑ Dynamics
The MRX lets you specify four types of component that modify the dynamic range: Compressor,
Ducker, Gate, Limiter, and Paging Ducker. The illustrations used in the following explanation are
for the case of STEREO.
For components other than Paging Ducker, the bottom input is for inputting the key-in signal. For
Paging Ducker, the bottom input is for inputting the signal from the paging mic.
“Compressor” component editor
This type of signal processing compresses the dynamic range. Use this to prevent problems
that can occur in the sound if the input exceeds a certain level (threshold).
1 COMP [ON] button
Switches the compressor function between enabled and disabled.
