(B8) Compressor setting

C O M P R E S S O R – O F F

Setting Range

OFF (default), 1, 2, 3, 4, 5

Use the compressor to prevent power amplifier overload or to produce more easily heard sound by averaging the audio level. The number shows the compressor's effectiveness level, which can be set by rotating the Parameter setting knob.

1 (Peak limiter)

Provides a peak limiter function that protects amplifiers and speakers against damage caused by an excessive signal input.

This level is suited to speech applications.

2 (Peak limiter)

Provides a peak limiter function that protects amplifiers and speakers against damage caused by an excessive signal input.

This level is suited to musical applications.

3 (Sonic normalizer)

Equalizes the sound volume of reproduced BGM among CDs or pieces of music by boosting small sounds and lowering big sounds, making the entire sound volume uniform.

This level is suited to BGM reproduction.

4 (Speech leveler)

Makes paging calls easier to hear by equalizing the difference in speech signal volume that may result from individual differences in speaker voice volumes or variations in speaker-to-microphone distances.

Since the volume is extensively corrected, the feedback margin narrows, making it liable to occurrences of feedback. Therefore, special care must be taken when installing microphones and speakers.

This level is suited to microphone speech applications.

5 (Speech leveler)

Makes paging calls easier to hear by equalizing the difference in speech signal volume that may result from individual differences in speaker voice volumes or variations in speaker-to-microphone distances.

This level 5 is more effective than level 4 described above. Since the volume is extensively corrected, the feedback margin narrows, making it liable to occurrences of feedback. Therefore, special care must be taken when installing microphones and speakers.

This level is suited to microphone speech applications.

(B9) Delay ON/OFF setting

D E L A Y – O F F

Set the delay function to ON or OFF.

When ON, the delay time setting follows.

Setting Range

ON, OFF (default)

ON: The delay function works.

OFF: The delay function does not work.
