Excellent working unit. Includes IEC power cable and rack mount bolts/washers.

The TC Electronic M300 is a 1U rack-mount multi-effects processor that combines legendary studio reverb with a versatile multi-effects engine. Celebrated for its intuitive, knob-per-function front panel, it delivers pristine 24-bit audio quality without the hassle of navigating deep digital menus. The M300 is heavily favored by both live musicians and studio producers for its flexible dual-engine architecture.

Core Features

  • Dual-Engine Architecture: Runs two separate effects processors simultaneously (e.g., Delay + Reverb).
  • Engine 1 (Multi-Effects): Features 15 classic algorithms including delay (up to 5 seconds), chorus, flanger, phaser, tremolo, compression, and de-essing.
  • Engine 2 (Reverb): Provides 15 dedicated, true stereo reverb algorithms (including Halls, Rooms, Plates, and Spring) based on proprietary TC Electronic technology.
  • Presets: Contains 355 presets in total—256 factory presets and 99 user-programmable slots.
  • Connectivity: Offers 1/4" analog inputs/outputs, RCA S/PDIF digital I/O, MIDI In/Out, and a footswitch jack for remote bypass.

Interface & Usability

Unlike many digital multi-effects from the era, the M300 skips complicated screens and sub-menus in favor of tactile knobs and buttons. This tactile approach allows users to quickly dial in parameters such as decay, pre-delay, and effect depth on the fly. The front panel also includes an Input Gain knob with a 3-color LED for immediate visual feedback on signal levels, as well as a master Wet/Dry mix knob. [

Technical Specifications

  • Audio Quality: 24-bit AD/DA converters and 24-bit memory structure.
  • Sampling Rate: Supports 44.1kHz and 48kHz for S/PDIF digital integration.
  • Routing: Supports serial and dual mono routing for varied signal chains.
