Built to a specification, not a price. Vintage ex-BBC Glensound MX6 mixer 6ch with 6ch sidecar. It came from BBC London OBs. Sidecar comes with a metal flight case and umbilical.

It has 12 x 936c mic channels, with transformer balanced mic inputs, phantom power, phase reverse and 45db pad. Proper, musical EQ on each channel, treble, semi parametric mid & a pultec type bottom end, where you can use the filter to slope down the bass from 20 or 220 Hz (7 positions between) & then use the bass boost to push it up, creating a hole in the lower mid.. These mic channels are capable of providing ample amounts of gain if you have ribbon mics etc.. 
The channels, mix and Aux 1 outputs are via P&G conducted plastic, linear faders, Aux 2 and the Clean Feed outputs are via rotary pots. There are 2 aux sends per channel (labelled misc 1 and 2), switchable between pre-EQ, pre- or post-fader.

Each channel has 2 insert points on bantam jacks (one pre fader, one post fader). These can be used as direct outs, allowing you to use this mixer as a fantastic sounding front end for your DAW.  

The master bus has a built in compressor (which can be bypassed if not needed). Left and right channels can be linked or unlinked. Release time switchable fast/slow. Threshold switchable +4/-4. 

The desk will output left and right channels (on male XLRs -  BBC didn't want external kit plugged in or out) and also a mono channel at the same time. You can also patch straight into the compressor (via bantem jacks) allowing you to just use this unit as a compressor if desired. To the right of the master channel, there is metering, tape sends and a cue bus with headphone output. Lots of redundant telephone gubbins which you might use to run some of your operation.

The XLR headphone outputs are split feed - wiring diagram via Canford. This was so you could plug headphones into a regular GPO patchbay to check signals but is not usual outside the BBC. I seem to recall the main headphone socket is B gauge but normally wired.

A manual in pdf and print will be supplied. Reason for selling - don't need 2 sets of the same equipment!

All in all this is an incredible sounding vintage mixer, with great mic pres, very flexible routing options, a great stereo (and mono) bus and a stereo compressor. All the channels work properly, there are no crackly pots or faders. This thing is incredibly solidly built (as with most BBC stuff) and is designed to last.
