"I have a number of the MTR active DI's, and the newest of them has given over 6 years trouble free service - the oldest is nearer 20."
- Peter John Chivers

"Another happy user of MTR active DIs. Note these DIs do not have transformers in them, so they have an interesting set of tradeoffs; they have extended frequency response compared to lesser transformer equipped DIs, so bass gtr is not a problem. It also means they never truly ground lift, and it means they never get inductive coupling from the mains or output transformers of the amp they are sitting on. All that said, in practice, they work, and work well".
- David Buckley

"Thanks for a couple of excellent pieces of kit: just got two D1-2s to add to my DI-3: a 15-year old veteran that is still going strong!"
- Mike Willoughby - melodeon, bouzouki, guitar, harmonica with Ceilidh band Striding Edge

"I have been using MTR DI boxes for over 10 years now with flawless performance and these dual passive ones are no exception. I have always found them to be well built. You get the feeling you could drop them from a lighting rig and they'd still work. The sound quality is also very good. The features are very user friendly with a ground lift, a -10dB and -20dB level reduction switch for hot signals and a link output for connecting a separate amp or monitor. The value of these are very good as well. I have used cheaper brands but the quality just isn't as good."
