Unbalanced TS or balanced TRS?

Is that where you see geometric shapes of fluorescent colours slide across your eyes?

Is there a common connector used by all standards and makes of keyboards?

This is based on a message I sent to @JohnDaBass. My first outing at Open Mic night . I used a single Sub with two tops for an open mic on thr 12th Feb. I took one sub, it sounded good. I hade the sub set to 125Hz and in hindsight should have used 80Hz. I also had the HPF on 90 Hz on the Wharfedale’s and should have let the sub’s crossover take care of that. Over all the sound was good I did not want it Bass heavy but in the event had to boost a bit around 100-120Hz. In My band currently have no gigs until May at the moment so next outing is March Open Mic on March 12th. I will probably try feeding the sub(s) from an aux feed then. It was frustrating not to be able to just go and turn the sub up at times. Using Aux Fed subs means I can use the PEQ on each output to suite both subs and tops, rather than relying on what different manufacturers choose for crossover/ LPF/HPF frequencies. In a band setting, I would not be out front so the Open mic is great for learning what the gear can do. I did put the Kala UBass through it and it sounded nice, although I don’t expect bass will go though it that much at Open Mic. One of the performers had a Fender Acoustasonic guitar and it sounded great through the system. In reality I did. It really need the Sub, there was plenty of bass coming out of the Typhon 8 AXFs. However there may well be a couple of keyboards coming next month so will take one or both. On Thursday, I could have made do with just the Typhon 8s. There quoted response +/- 3dB is 65Hz to 20 KHz, enough to be used as a bass cab in all but Dub.

Wax candles work well on stiff zips too.

Well I ran my first open mic night yesterday at the Legion in Broadstone, Poole. I knew that one of the best Open Mic'ers around was on holiday, and although I have been pushing it for three weeks, I have not had much interest. I used my new Wharfedale Typhon 8AXFs and a single Citronic Casa 10 Sub. I mixed it through my A&H CQ20R mixer using two mics, one a Sontronics Solo, the other was a Behringer BA85A. Two feeds were also connected for instruments. Initially the sound was odd, then I realised that the LH top was set way down on the speaker, and it came to life. There seemed to be no performers present until I said that people could sing to a backing track. One of the lads got up and said he would get his guitar from the car. He told me later that it was a fluke that he had his guitar in the car, and he had not heard that open mic night was happening. I was shocked when he walked back in with an Acoustasonic, and he proceeded to play 6 songs, showing some real skill on the guitar. Later, another chap said he came, although he had almost lost his voice. Both he and Acoustasonic man said that they would be back next month. Finally, a few people got up and sang along to backing tracks. So although the attendance was small, I am encouraged that younger lad said he would bring his Dad on Keyboards next time and Chris, always good for playing as long as you want, is back next month. I am looking forward to it already.

You do have to think of this as a complete system problem, so the string will change things, as do the machine heads. One other thing that I have heard and I think it improved things, was to loosen the neck boys while tuned to pitch. This force the me as far into the neck pocket as it can go. Tighten the screws while still under tension. The other issue is shims, I have no evidence but the charge in contact area suggests a change in resonance. The other thing Fender found was that 2x2 headstocks work better than 4 in a line re dead spots. My Sire M2 has no obvious dead spot. The neck bolts are also staggered, is that crucial? Any luthiers want to comment? @Jabba The Hutt @manton @AndyJR81

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.
