I needed a simple solution to drive 3 pairs of studio monitors without much hassle and the t.racks DS2418 gave me exactly that. It takes up only 1U in the rack, has an IEC connector (kettle lead) for power, and XLR inputs and outputs for audio.
After opening the box I was surprised that the device is lot heavier than expected, but I quickly realized why. It is built like a tank, and judging by the weight I would say there is a decent power supply inside, which is also supported by the fact that I could not hear any signal coloring or degradation, the unit sounds completely transparent.
Setting up things couldn't be any easier, I just plugged my audio interface directly into the DS2418, plugged in the speakers, selected the 2x4 configuration for stereo distribution, then matched the gain of the different speakers with the little dials on the front panel and I was ready to work. The only thing I'm missing is a mute button for each channel which would be handy for A/B/C/D switching between speakers.
Overall, I'm very happy with the DS2418, it is a sturdy and reliable piece of kit that solves a specific problem very well in my studio.
