Many quality jack socket have what is called self-wiping contacts. If you don't insert a plug, it will leave the contacts to tarnish.

Rotary encoders are now common as a replacement for pots in the digital world. They work by indicating whether to increase or decrease the level of a given parameter. For example, they are often used on home cinema systems as control but can also be used to select menu items. Any PA speaker with DSP and a display will incorporate one. They often incorporate a push switch so you push to enter a menu, then rotate to select a menu item. If you want to know whether you are using a pot or a rotary encoder, the best way to tell is that pots have up to 300 degrees rotation before you hit the end stop, a rotary encoder will go round and round a round if you turn it. This picture shows one on an active speaker, The one with the purple blob.

You have a rotary encoder U12 that could be interesting. I will investigate more soon.

Don't go beyond 12 0'clock, there be dragons...

Expression pedal, whether analogue or rotary encoder, suggests that rotary controls are possible.

Fender, (when it was Fender), researched into this many years ago and concluded that if you want to eliminate the dead spot, eliminated the headstock. Then change to a composite neck.

I am impressed, as it is "just" foot switches, I assume there is no way of adjusting values by MIDI?

Exactly what I found with the Mesa D800 Voicing control, at home, wonderful. In the mix, I had to turn it off.

I think the drawing in post1 was amended after your suggestion as those are the dimensions on my copy of the drawing. Thank you.

Any update on this?

I am sure that I saw somewhere that you can get two of these from a half sheet 1220 x 1220, Is this correct?

So to try to clear up any confusion, a 2 pole SpeakOn cable connector will mate with either a 2 or 4 pole chassis connector. A 4pole cable connector will ONLY mate with a 4 pole chassis connector. So rule of thumb, 2 pole on cable and 4 pole on the chassis.

I think many manufacturers are let down by their cabs.

In a bar you buy beer by the pint and spirits in cl.

It frustrates the hell out of me, Brits using Imperial measurements. I am 74, I grew up with the Imperial system but when I started in Engineering in the late 60s, I had to change to the SI system. Imperial disappeared for the public 50 odd years ago. Get over it. You would not want to buy something fitted with UNC or UNF threads on the screws, why live your life in the past? Now I have to decide whether to take my 34" or 30" bass to rehearsal.🤣

Have you got a spare power supply? It is probably prudent to have one just in case the supplied one fails anyway. https://support.allen-heath.com/hc/en-gb/requests/new Allen and Heath UK Tech Support Form. distribution is by Audio Technica https://distribution.audio-technica.eu/en/allen-heath/

Thanks. Looking at the block diagram, it appears that the Mute is achieved in the preamp, that means that the power amp is always operational. Most manufacturers use the internal mute function in the power module.

We are going to do this. Will listen to your take ion it with interest. Some time later --- YES, you play it properly, so many don't play the full riff.

Ashdown amps are usually flat with the controls at 12 o'clock.

Does the noise happen with mute engaged on both channels?

A question, why are all the EQ knobs a fully anticlockwise?

I am no fan of much modern music and was surprised to see the angst in the thread on the insolvency of Native Instruments. I must also add that the practice in the “covers” circuit of pubs and social clubs calling professional Karaoke singers “Solo Artists”. I am also thinking back to my realisation that some of the best singers are now “Solo”. This has, in my opinion, really badly affected the quality of singers in bands. From the financial point of view, it makes sense, A “Solo” singer can make £150 in a night whereas a band charging £250 means each member gets £50. Of course we have to avoid the filter of nostalgia, a quick listen to any retro radio of TV station will prove that a high percentage of 60/70s music was awful, despite being probably the most innovative period in my lifetime. Changes in music seem to come in strange ways, witness the way that white people from here, (re)introduced the Blues to America. It is probably one reason why we should all consider the History of Music to give ourselves a real understanding of why we do what we do. As a creator of electronic music, you need the basics that training coming from a long apprenticeship. The alternative is some soulless, brain crunching morass that sounds akin to my own early experiments on electric guitar, bloody awful. So as someone from a guitar based band, struggling to get gigs in a world where the “empty orchestra” is Emperor and the only real live music is the clinking of glasses at closing time, I don’t understand the chagrin over the feared demise of Native Instruments but I can empathise with it. On reflection may be I should be more accepting of Valve Amp purists. They worship the failings on the technology for what it adds to the music and as music is our religion, perhaps I/we should all be more tolerant of the different denominations. Of course the devil AI music must be rooted out at all costs. The old ways are the best of course so initially I suggest ducking the servers in water. If they fail and die, they are innocent, should they still work, they are evil and must be burnt at the stake. In the words of the great Ozzy Ai, AI,AI,AI all aboard the Crazy Train.

To be honest, the cabs are a bit Marmite. At two consecutive SW bass bashes, we had cab shoot-outs and Mark Bass came top one year and bottom the next.

My old UI16 had a brick power supply, and it was a pain, one of the reasons I went for the CQ20.
