The RME QuadMic is a compact, 4-channel portable analog microphone and line preamp originally designed as a mobile companion for RME's computer interfaces and recording systems (such as the Hammerfall DSP / Multiface series)

Channels: 4 independent channels

Inputs: Balanced microphone and line inputs via Neutrik XLR/TRS combo jacks

Outputs: 4 balanced TRS line outputs on the rear panel

Per-Channel Controls: Switchable +48V phantom power, low-cut filter (80 Hz, 18 dB/octave), and phase/polarity reversal

The only issue this unit has: The power jack needs to be aligned a certain way to pass power, you may have to turn it slightly when plugging in to get it to seat correctly. I have never had an issue with it shutting off or not working once plugged in and powered on. This unit has been in my rack at the studio for 6 months, sounds great and works as it should. I've simply outgrown the need for it after getting the Clarett Octopre.

included working psu and the 19" rack fins for it, as these were originally sold with tiny half rack fins.
