(A9) HPF and LPF settings (when the D-001T is used)

H P F – 4 0 0 H Z L P F – 1 2.5

Rotate the Parameter setting knob to set the cut-off frequencies.

Press the Right or Left shift key to select HPF or LPF, of which parameter that flashes can be adjusted.

Setting Range

HPF

LPF

OFF (default), 20, 25, 31.5, 40, 50, 63, 80, 100, 125, 160, 200, 250, 315, 400 Hz

OFF (default), 4 k, 5 k, 6.3 k, 8 k, 10 k, 12.5 k, 16 k, 20 kHz

(A10) Compressor setting (when the D-001T is used)

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.
