Chapter 5. Basic operation for output channels Compressor settings You can use the COMPRESSOR section of the SELECTED OUTPUT CHANNEL block to manually control almost all of the compressor parameters. Hint The compressors of the PM1D system allow you to select one of three types: COMP (compressor), EXPANDER, and COMPANDER. However, it is not possible to select the type by operations on the top panel. For this reason, you must first load compressor data of the desired type from the library, and then use the SELECTED OUTPUT CHANNEL block to edit the parameters as desired. Separate libraries are provided for the input channel compressors and output channel compressors. Compressor data cannot be loaded into the opposite type of compressor. The controls and functions of the COMPRESSOR section are shown below. COMPRESSOR ATTACK/ RELEASE [TIME] encoder and [VALUE] indicator This sets the attack time/release time of the compressor. Use the switch located at the right to select either ATTACK or RELEASE, and use the [TIME] encoder to adjust the value. The current value is shown in the [VALUE] indicator. COMPRESSOR [RATIO] encoder and [VALUE] indicator Use the [RATIO] encoder located at the right to adjust the ratio of the compressor. The current value is shown in the [VALUE] indicator at left. COMPRESSOR FILTER [ON] switch and LED The [ON] switch located at the left is an on/off switch for the HPF or LPF located before the internal compressor. The [FREQUENCY] encoder at the right sets the cutoff frequency of this filter. The current value is shown in the [VALUE] indicator. Hint The HPF and LPF cannot be used simultaneously. The selection of either HPF or LPF is made in the display (OUT COMP function COMP PRM screen). COMPRESSOR FILTER [FREQUENCY] encoder and [VALUE] indicator COMPRESSOR [LINK] switch and LED This specifies whether the compressors of adjacent odd-numbered → even-numbered MIX channels or MATRIX channels will be linked by the key-in signal (link=on), or whether the compressors will operate with independent key-in signals (link=off). (The LED will light when link is on.) For details refer to "CS1D Reference Manual (Hardware)" (→p.61). COMPRESSOR [GR] meter LEDs These LEDs indicate the amount of gain reduction produced by the internal compressor. COMPRESSOR [POST] meter LEDs These LEDs indicate the level of the signal after being processed by the compressor. COMPRESSOR [PRE CLIP] LED This LED will light when the signal clips before passing through the compressor. COMPRESSOR [GAIN] encoder and LEDs This sets the GAIN parameter of the internal compressor. The approximate current value is shown by the perimeter LEDs. COMPRESSOR [ATTACK]/ [RELEASE] switch and LED COMPRESSOR WIDTH (dB)/ KNEE [TIME] encoder and [VALUE] encoder When the compressor type is COMP or EXPANDER use the [TIME] encoder to set the KNEE parameter of the COMP or EXPANDER. (The [KNEE] LED will light.) COMPRESSOR When the compressor type is COMPANDER use the [TIME] encoder to set the WIDTH parameter of the COMPANDER. COMPRESSOR [ON] switch and LED This turns the internal compressor on/off. COMPRESSOR [THR] encoder and LED Set the THRESHOLD LEVEL parameter of the internal compressor. The approximate current value is shown by the perimeter LEDs. 81
