From Darkglass:

"The Hyper Luminal Compressor features the first hybrid design in a compressor pedal: an analog VCA controlled by a digital side-chain allowed us to capture and include the characters of some of the most legendary compressors in history while keeping the signal path completely analog."

• Blend control to mix the clean and effected signals
• Time control to adjust both the attack and release of the compression
• Compression knob that adjusts both the overall amount of compression and the internal makeup gain
• Three compression modes - BUS, FET, and SYM
• Micro USB B connector to connect to PC/Mac for Darkglass Suite software
