The TC Electronic Triple C is a 1U rackmount digital dynamics processor released in single-channel and stereo versions. It combines three distinct processing modes into a single hardware unit: 

Core Processing Modes

• Full-Band Compression: Standard analog-style dynamics processing featuring a digital tube-warmth emulator (Digital Radiance Generator with up to 11 stages), soft limiting, look-ahead (3ms), and 50 factory plus 100 user preset styles. 
• Multi-Band Compression: A 3-band compressor (low, mid, high) with adjustable shelving crossover filters ranging from 19.95 Hz to 20 kHz and a 3-band gain reduction meter. 
• Envelope Compression: A transient-shaping mode inspired by the SPL Transient Designer that lets you alter and scale attack and release levels (by up to ±20 dB) on percussive material. 

Hardware & I/O Specifications

• Conversion & Processing: 24-bit internal processing with 128x oversampling A/D conversion. [
• Connections: Balanced TRS analog I/O, S/PDIF digital I/O, MIDI implementation, and side-chain input support. 
• Interface: Dedicated single-function knobs, a system parameter wheel, a 23-character digital readout, and dual VU meters.
