Welcome to our website for the 1963 BBC MCR21 OB Van

This is the production desk with the 10 channel cut & A-B mixing. Split fader operation was possible and a selection of wipes could be used.

The Sound desk had 20 channels divided into 3 groups, provision is made for PA outputs and extensive monitoring. There is no provision for equalisation, it is a flat response mixer. In case of power failure the whole sound chain of the MCR reverted to battery operation.

The Engineering Managers desk had the manual telephone exchange and good talkback facilities.
