CS1D Operating Manual (Basic Operation) Using the compressor By using the COMPRESSOR section of the SELECTED INPUT CHANNEL block, you can manually operate nearly all of the compressor parameters. Hint The compressors provided by the PM1D system allow you to choose from three types: COMP (compressor), EXPANDER, and COMPANDER. However, the choice of type cannot be made from the top panel. For this reason, you must first load compressor data that uses the desired type from the library, and then use the SELECTED INPUT CHANNEL block to adjust the parameters as necessary. The COMPRESSOR section contains the following controls and functions. COMPRESSOR [RATIO] encoder and [VALUE] indicator The [RATIO] encoder located at the right sets the ratio of the compressor. The current value is shown by the [VALUE] indicator at left. COMPRESSOR FILTER [ON] switch and LED 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 by the [VALUE] indicator. COMPRESSOR [LINK] switch and LED This specifies whether compressor operation for pairable input channels will be linked by the key-in signal (link=on) or whether the compressors will operate independently (link=off). (The LED will light if link is on.) For details refer to "CS1D Reference Manual (Hardware)" →p.26. 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 COMPRESSOR FILTER [FREQUENCY] encoder and [VALUE] indicator Use the [ON] switch located at the left to switch on/off the HPF or LPF placed before the internal compressor, and use the [FREQUENCY] encoder at the right to set its cutoff frequency. The current value is shown by the [VALUE] indicator. Hint The HPF and LPF cannot be used simultaneously. The selection of either HPF or LPF is made in the display (IN GATE/ COMP function COMP PRM screen). COMPRESSOR [ATTACK]/[RELEASE] switches and LEDs COMPRESSOR [WIDTH (dB)/KNEE] encoder and [VALUE] indicator If the compressor type is COMP or EXPANDER Use the [WIDTH (dB)/KNEE] encoder to set the KNEE parameter of the COMP or EXPANDER. (The [KNEE] LED will light.) If the compressor type is COMPANDER Use the [TIME] encoder to set the WIDTH parameter of the COMPANDER. COMPRESSOR [PRE CLIP] LED This LED will light when the signal clips before entering the compressor. COMPRESSOR [GAIN] encoder and LED This encoder sets the GAIN parameter of the internal compressor. The approximate current value is shown by the perimeter LEDs. COMPRESSOR [ON] switch and LED This switches the internal compressor on/off. COMPRESSOR [THR] encoder and LEDs This sets the THRESHOLD LEVEL parameter of the internal compressor. The approximate current value is shown by the perimeter LEDs. 52
