This is the default compressor module when using ProChannel on a bus. This module is based on
the legendary center console stereo bus compressor in one of the world's most successful analog
studio production mixing consoles. Known to add punch and drive to a mix. Also recommended for
instruments like piano and drums. This mode supports sidechaining.
The PC4K S-Type Bus Compressor module contains the following controls:
• Clipping LED. Shows if the input signal to the Compressor module is clipping. If there is any
distortion in the ProChannel signal chain, the clipping LEDs let you identify where the clipping
occurs.
• Compressor enable/disable . Enables/disables the PC4K S-Type Bus Compressor module.
• VU meter. Shows the amount of gain reduction.
• Thresh. Sets the level at which compression occurs. If the input signal level is below the
threshold, no compression takes place. If the threshold level is reached, compression (i.e.
automatic gain reduction) occurs, reducing the gain of the input signal according to the Ratio,
Attack and Release settings. The valid range is -30 dB to +20 dB, and the default value is -10 dB.
