TC Electronic M One XL


In stock


The M One XL is a mid-range reverb / effects unit in a neat 1U box. It’s a twin-engine device so can process two signals at the same time. The engines can be used in parallel or as dual-mono with stereo outputs. Dual mono gives two separate effects, making the XL two effects units in one

The XL is an updated version of the earlier M One and adds more memories (200 presets rather than 100), XLR connectors and a number of additional reverb and delay programs. Both have a full Midi implementation with System Exclusive messages, program changes and real-time Continuous Controllers

The M One XL has great connectivity:

  • two channels of balanced analogue audio inputs & outputs on XLR connectors
  • SP/DIF digital in & out on phono connectors
  • Midi in / out / thru on 5-pin DIN midi connectors
  • Footswitch input on a jack socket
  • Universal auto-switching mains power supply (100-240 VAC) with standard IEC connector

The M One XL is ideal for use with a DAW, via the built-in SP/DIF digital ins & outs, allowing processing to stay in the digital domain

It’s equally at home in an analogue setup with professional balanced inputs & outputs on XLR connectors. Inputs & outputs are stereo and processing can be stereo or split into two separate 1-in, 2-out effects

“Like its antecedent, the M One XL is easy to use at either a basic level or as a power user — and delivers stunning results for the money. I liked the original very much, and the new XL is even better, yet costs exactly the same. This is a serious machine capable of delivering very competent professional results, both technically and aesthetically. Well worth fitting into your effects rack.”

“The M One XL offers a worthwhile improvement on the original, not least by including twice as many factory presets — all of which are usable from the off”
The M One XL makes an interesting alternative to a Lexicon reverb / effects unit. With balanced XLR connections plus SP/DIF digital i/o it’s easy to integrate it into an existing rig and, with hundreds of high quality presets and excellent editing facilities, it’s an effects unit that will cover lots of bases

The next step up the TC Electronics food chain is the M2000 but, for those on a tighter budget, the M One XL will be ideal

The M One XL is clocked internally at 48 kHz and will sync to incoming digital signals at 44.1 and 48 kHz. AD/DA convertors are 24-Bit with 128 x oversampling. Internal processing is 24-Bit and the unit supports 24-Bit digital inputs. Output dither is switchable. Digital connections are SP/DIF via the usual phono connectors. Analogue inputs & outputs are balanced on XLRs with a nominal operating level of 0 dBu and maximum input & output level of + 24 dBu. See also the Tech Specs link above
