Information shown in the display Function menu ❏ COMPANDER HARD (COMP.(H)) ❏ COMPANDER SOFT (COMP.(S)) The hard and soft companders combine the effects of the compressor, expander and limiter. Output Level THRESHOLD Input Level 0dB WIDTH The companders function differently at the following levels: 1 0 dB and higher Functions as a limiter. 2 Exceeding the threshold Functions as a compressor. 3 Below the threshold and width . . . . Functions as an expander. The hard compander has an expansion ratio of 5:1, while the soft compander has an expansion ratio of 1.5:1. The expander is essentially turned off when the width is set to maximum. The compressor has a fixed knee setting of 2. * The gain is automatically adjusted according to the ratio and threshold values, and can be increased by up to 18 dB. * The OUT GAIN parameter enables you to compensate for the overall level change caused by the compression and expansion processes. Parameter THRESHOLD (dB) RATIO ATTACK (ms) RELEASE (ms) OUT GAIN (dB) WIDTH (dB) Range -54 to 0 (55 points) 1.0:1, 1.1:1, 1.3:1, 1.5:1, 1.7:1, 2.0:1, 2.5:1, 3.0:1, 3.5:1, 4.0:1, 5.0:1, 6.0:1, 8.0:1, 10:1, 20:1, (15 points) 0-120 (121 points) 44.1kHz: 6 ms - 46.0 sec 48kHz: 5 ms - 42.3 sec 88.2kHz: 3 ms - 23.0 sec 96kHz: 3 ms - 21.1 sec (160 points) -18.0 to 0.0 (181 points) 1-90 (90 points) Description This determines the level at which compression is applied. This determines the amount of compression. This determines how soon the signal is compressed or expanded once the compander has been triggered. This determines how soon the compressor or expander returns to the normal gain once the trigger signal level drops below or exceeds the threshold respectively. The value is expressed as the duration required for the level to change by 6 dB. This sets the compander's output signal level. This determines how far below the threshold expansion will be applied. The expander is activated when the level drops below the threshold and width. Global functions Output functions Input functions Appendices PM5D/PM5D-RH V2 / DSP5D Owner's Manual Reference section 323
