The '''''Behringer Eurorack MX2642A''''' 26-input 4-bus [[Sound board | mixing console]] is one of YSTV's spare sound desks. Typically used for ''medium-sized'' OBs that aren't worth the hassle of taking the [[Allen and Heath ZED 428|ZED 428]] (for example shows requiring multiple [[Microphones|mics]] but no mixing of music). | The '''''Behringer Eurorack MX2642A''''' 26-input 4-bus [[Sound board | mixing console]] is one of YSTV's spare sound desks.

== What's in the Box == | |||
Repair work in October 2013 provided a great excuse to have a nosey inside the Eurorack's case. A set of schematics was also ''acquired''. There are a few notes below that will hopefully be helpful for any future repair work. | Repair work in October 2013 provided a great excuse to have a nosey inside the Eurorack's case.

====="Channel 1 does not send to main/group mix"===== | ===== "Channel 1 does not send to main/group mix" ===== | ||
Further testing revealed that whilst the channel sent to auxes 1 and 2, auxes 3-6 and the group and main mix buses (everything post-fader) received no signal. The original ALPS RS6011 10K P series linear potentiometer was difficult to obtain in Europe, but fortunately [http://onecall.farnell.com/ Farnell] stocked a suitable replacement: RS6011Y10K. The pot fit in the space on the PCB (although it didn't have reinforcing lugs), but a little careful work with the hacksaw was required to shorten the fader control to the same length as the others. | |||
===== "Channel 7 XLR port is dead"; "Channel 8 is far too quiet (probably a dead preamp)" ===== | |||
Initial testing suggested that channel 8 was working, but that channel 7 had a faulty mic preamp; channel 7's mic input was very quiet but the line input seemed OK. However, in the stage-by-stage analysis of of the channel that took place when the case had been removed no problems could be found. Both channels would go on to work perfectly with mics in the recording of [[Have I Got News For York]] that took place at the end of the month. Failing an act of cunning sabotage by [[hist:University Radio York|URY]], the only credible explanation that anyone could think of at the time was a dodgy solder joint that was knocked back into place whilst removing the PCB from the case. If either of these channels doesn't seem to be working as expected, please don't hesitate to contact the techies as above. | |||
== | == Retirement == | ||
As of 2019 the functional status of the MX2642A is, at best, questionable. It has been completely replaced and is not used any more. | |||
