About the GL 2S3 Compressor
Discover the magic of the Greenbox GL 2S3, an Opto Compressor based on the compression of the classic CL 1B, but now in a 2-channel solid-state version.
Inspired by the classic CL 1B, the Greenbox GL 2S3's circuitry features a solid-state circuit with discrete components, preserving the essential compression characteristics of the original model but going even further, offering an expanded range of sonic possibilities.
And to complete this package of extraordinary features, the Greenbox GL 2S3 is equipped with a special output transformer, built based on the original model, ensuring performance with the same characteristics as the original model.
BETTER UNDERSTAND CHANNEL LINKING:
This 2-channel compressor can be used in two different ways: with the sidechain linked or with the sidechain independent on each channel. When the link switch is on, the two sidechains work together. If you add more gain to the input of channel 1, channel 2 will receive more signal in its sidechain and will compress more.
The Attack and Release times, as well as the Ratio, should also be set equally on both channels, as this will allow the compression to act equally on both channels. The link switch serves solely to ensure that the signals from both channels pass equally to both sides of the sidechain. To better understand, let's use an example: If a signal is applied to channel 1, this signal will enter the sidechain of channel 1 and channel 2 equally when the link switch is on, and the same occurs on channel 2, causing the signal to enter the sidechain of channel 2 and channel 1 equally. However, if the link switch is off, the signal from channel 1 will only enter the sidechain of channel 1, and the signal from channel 2 will only enter the sidechain of channel 2.
Note: The link switch only performs sidechain joining (compression), without any crossover or joining between channels in the audio signal flow.
