the t.racks DSP 4x4 Mini Amp

As the name suggests there is a DSP onboard, but the ease of use and range of settings are more than I had hoped for. Paired with the speakers I had purchased for the project each 'zone' was set with hpf at the required frequency as lited in the manual. The multiband eq was then adjusted to suit the desired output and appropriate gain and limiter set. There was plenty of power available and the clarity was fantastic. Over all a nice tidy enclosure and a very easy to use interface for adjustment. Fantastic product for the very reasonable price tag.

Once I got my test gear out found that mine was putting out 458KHz at an amazing 289mV RMS, as measured by my Fluke 867B graphical multimeter.
Ive tested it against over small power single chip digital amps and there is no significant measurable background output.
Im awaiting their technical guys, hope this is a one off as i really like the unit. The DSP side of it works well with what its designed for.
The addition of the amplifiers is good and if it all gets sorted i will be using more.

Thought this was the ideal
Product to combine with sonos. Loads of control settings, sound is good so looked good. I have a feeling that they all will break. No garantee because they die after the 2 years warranty! So this product sucks in reliability!

This amp / DSP is great for the price, it produces a clear enough / load enough sound sound for voice reinforcement when paired with the 4 x Achat 104 speakers.

First Impression - Seems like a nice solid, compact unit. Good features for the price and very happy with the build quality - but you've got to make it mac compatible with a downloadable software! I can't believe in 2025 I'm digging out an old windows laptop and inserting a tiny CD. This is nearly there to being a 10/10 piece of kit.
