You have to consider the system as a whole, with today's digital equipment there are delays, latency, propagation delay caused by both ADDA conversion and the finite time that the signal passes through the digital stages, each gate that the signal passes through causes a delay by any other name as transistors, the basic building blocks, cannot switch instantly. These delays happen in digital pedals, mixers, digital wireless systems for instruments and IEMs. The amount of latency that you can hear varies between people, and some chain to be able to hear 2mS. The is ballcocks, it is equivalent to one cycle at 5Hz. So latency adds any one component does not usually add an excessive amount. Analogue, as @Phil Starr says, has a compander, really a compressor, at the input and an expander at the output. This compresses the signal as it goes in to enable more channels to be used, and expends it as exactly as it can at the other end to rebuild the original system. Most analogue systems use UHF bands and frequency modulation FM. In most cases, the better the design, the better the end result. There are really two rules of thumb before you buy anything wireless. Do not buy anything on the UHF 863-865MHz band, and do not buy anything in the 2.4GHz band. Finally, do not listen to Scott Uhl on YouTube. The rules in the USA are very different, and most of the UHF systems he recommends are illegal in the UK.

To an extent, I agree with you, but one issue with passive electronics require a relatively high input impedance in the amplifier, mixer, pedal. High input impedance basically equals high noise or hiss. Of course, if you are one of those nutters people that prefer true bypass, there is no hope for you. As someone that makes cables for people, it is in my interest for people to need better cables and to make the case for a quality low loss cable but yes a Wireless system does effectively make the bass active (or more correctly buffered). Of course, I also make cables to replace the ones supplied by Shure Sennheiser and Line 6. Personally, I use both passive and active basses but if the Fender Precision were introduced today, Leo would have installed a pre-amp (MusicMan?).

Buffer?

Enable is the input used to mute the amp.

I have used Sticky Stuff to good effect in the past. It is designed to remove sticky labels but does not seem to damage surfaces and I have used it all over the house as well as for Tolex/Vynide. However, try the cheaper options first.

You will not find any service information for the amp, as with all major class D makes, Powersoft, Pascal and ICEPower do not publish any service information. The upside is the we, the users get a well engineerded power amp that saves on development time and keeps purchase prices low. The downside is that you cannot easily service them. Looking at the block diagram, the mute circuit is very early in the signal chan so it is likely that you power module is working. One small issue with this series is that the auxiliary supplies that power the preamp and signal balancing circuits are protected by fuses on the pcb. If there is a fault on the these lines you may get no output from the small signal circuits. These are hard to find and even harder to replace ( yes experience talking). In reality it really is a job for an amp tech, I am wary about advising on mains powered devices online.

The mighty Gut.

Before you do anything make sure it is the power module. The fact that the MUTE button mutes the hiss suggests that the failure is not there but elsewhere. Those modules are not especially noisy on their own. Before the module there will be a preamp and a balancing circuit as the 250ASX2 is it is two amplifiers working in bridge or anti-phase.

Which makes me think that they are limiting to the driver minimum specs.

I assume that as they also make the drivers, they know the variations in specifications. Taking the that knowledge allows you to protect the drivers, limiting them to the minimum specs. You might also have some sort of dynamic impedance measurement to check the actual voice coil temperature, avoiding the worst effects of power or thermal compression.

I think this is a bit of manufacturer's marketing speak. All reputable Class D amps have several protection features built in and if you add DSP you can add more to suit the drivers. No manufacturer is going to use an amp that could really overpower a driver, and as far as I know, it is amp failure that powered speakers suffer from mostly*. * They may have improved, but the original Mackie Thump speakers, as well as many others, used a chip based Class D amp that they advertised as well over 1000 watts. Add the Thump name and no DSP and these little 2-300watts chip amps fried like eggs on a black car in the midday sun. Behringer also used these chip amps but rated them much more modestly.

To give it its full name. Spa Francorchamps, is being saved for the twin 18" cab. 🤣

Just a though, would smaller braces, at an angle, to brace the sides, top, bottom to each other.

I think this shows how they value you Daryl. Hang in there.

You can have first refusal on my Faital Pro 12PR320. Have sent a pm

Now I remember you. 😂

I think they will help, especially the inner chamfer. However of all the black arts in cabinet design, flared ports is the darkest. Whether there would be much improvement in copying say a precision ports design I don’t know. While flare reduce port noise, this really masks the port’s limitations caused by its small diameter. Of course I could be talking complete tosh.

I am sure others would speak either more authoritative voices but I don’t think wadding will help with low resonances.

Yes, I had the same experience.

VAT is a sales tax and in Europe/UK it is around 20%. It is some while since I was last in the USA but then, individual states levied their own sales tax. Annoyingly, the tickets price was without tax so you got a shock at the checkout. The last time I visited Sales tax was around 5-7%. That would have either been Nevada or Louisiana. 20 years ago. Taxes are higher in the UK than then USA but we generally have better public services. In Scandinavia, where taxes are higher, they have even better public services. Sadly taxation does not subsidise amplifier repairs.

Yes, There were a lot of good points to the Subway, the voicing control and deep switch were great. However neither worked that well for me in a band setting. The EQ was nice but I tend to run flat adding any colouring via my Zoom Pedals. I decided that I needed a better PA so sold it on. It was very well built, a tad utilitarian in its design but if I wanted to go pedaless would have probably been a keeper.
