New monitor controller day. Behringer Monitor 1. This thing is kick a$$. Pristine sound quality compared to the Mackie mixer I was using to control my monitors. The Mackie was a noisy POS tone suck. I cranked up the volume to max with nothing playing and it was completely silent. Solid build quality. XLR ins and outs, 1/8" TRS in and outs. No power supply needed.
