I used this amp to power either the PS 15 R2 or Nexo RS15 with Nexo controller.
I bought 5 of these amps, and they all work.
Not having the means to buy a fleet of NXAMP Nexo, I chose these amps for low blow and positive opinions they Thomann.
The sound is not ridiculous compared to a 4x4 NXAMP that ready yet costing 20 times more expensive.
I guess in the long term, the Nexo will still be there when the Tamp, ultimately we do not care (for the price).
This is powerful and clear. Against by the input level is not adjustable, suddenly the amp clips quickly.
Very pleased with this purchase, so, I also bought the 4 channel versions (TSA 4-700, the model above is not released yet) for RCF passive return, it works great, too. For the price, once again no complaints.
