The unit is easy to connect but not so easy to use. I use it on classical or choir live concert with a pair of Neumann electrostatic condenser. I take contact with Presonus which refuses any warranty as I moved to Europe and refuses to send me a copy of the power supply diagram. The general manufacturing quality is good but potentiometers are the poorest quality I have ever seen. Once repaired, it works without problem.
Sound quality is good.
Multi connector in, XLR and TRS balanced quarter inch outs. The noise level of the unit, at least when used with my Rode NT-1 condenser mic, made it impossible to use. We heard the noise while we were tracking male vocals and decided to go with it anyway. Back to the store with you, mi amigo. I can't give a fair assessment of this unit on other applications such as processing line level signals as I haven't done much with it.
