Just a heads up on the CQ series. The CQ18 has the screen which is great but the downside is that many of the connections are TRS rather than XLR. Having built in display and some assignable rotary controls is nice when migrating from an analogue console. It also means you are not tied to the vagaries of WiFi, although my CQ20 has been rock solid in that respect. It is miles better than the Soundcraft and Behringer small format digital mixers.

The safe load depends on the repetitions. According to the HSE, carrying two 23Kg loads would represent ba risk of muscular skeletal injury . https://www.hse.gov.uk/pubns/indg383.pdf

True, Airbus have been using CF wings for decades but they are extremely well braced. With corporations like Yamaha involved in loudspeaker design, as well as marine and motorcycles, you would think that CF would have been considered well before now.

However you will need a PA with bigger drivers/cabinets so that the audience can hear you so the savings are minimal both in cost and environmental terms. Carbon Fibre, like Fibre Glass is not strong or tough until you brace it. The bracing can be made from many different materials even wood. However to achieve the lightness, you have to make some compromises. The best example of this is the nose and front wing of an F1 Car. You only need a low speed coming together to make a real mess of these carbon fibre constructions. One of the earliest composite materials that I can across was in the early Ramsa/Panasonic WS-A series. These were of a resin construction but had external moulded ribs/braces and were incredibly strong. Some of you may remember the Elephant adverts where a full grown elephant has one leg on each of four WS-A200 speakers. I still have some of theses and they are at least 30 years old. Composites are a good material but that extra bracing comes at the price of weight. While not being the heaviest cabinets, they are by no means the lightest. Mike Arnopol, made some great versions of Dave ( Greenboy) Green’s designs in the US but he had to retire as the chemicals used had a massive impact on his health. So are we stuck with plywood? Yes and no. There are promising reports of the performance of bamboo ply. Bamboo is a grass and fast growing so environmentally friendly and reportedly, light and strong. At the moment is is still hard to get and expensive. Thankfully builders like Barefaced, LFSys, BFM etc push the boundaries in sensible ways.

I found that my Lenovo Android Tab has a lot of lag compared to my iPad so I can appreciate that. They are the same vintage but clearly the iPad is more responsive. Don't get me wrong, I grew up using analogue consoles and loved using them. My first Digital mixer was a 32 channel Panasonic DA7 and it was clear even way back that the physical controls were on the wane.

I have transferred @JohnDaBass's Free/Bad Co patch from the B1Four to the B2 Four. It works really well.

I will watch that video with interest later but I wonder if the need for a physical control layer is as much a "tablet phobia"? I have the CQ20 and after struggling initially with some of the finer points, I find the level of control I can get on an iPad is superb once you learn all the fine adjustment tricks. Te same was true of the Soundcraft UI16.

Try not to drill the hole too large and if it is hard to get the port in, freeze the port overnight.

Just a small tip, it the hole is a tad tight when fitting the port, put the port in the freezer overnight. The temperature coefficient of the PVC mean the port will shrink but gradually expand into the hole as it warms.

Last week, we used our ancient powered mixer and a pair of Ramsa 8s as the monitors. We have used them for a few gigs and not had a problem. This time, at soundcheck the drummer said he could not hear the monitors. of course I had forgotten that they have a narrow dispersion 60x60. Changing the angle solved the problem and made me realise that since using them we have had no feedback problems from the monitors. It is not something you always consider when looking at a PA speaker.

This was one of the reasons that I bought it. The HX Stomp has a TRS jack out and I prefer XLRs for DI.

Theoretically yes but in fact the Low B is not necessary or at least it's fundamental is not. When I did play 5 string I never needed a low B and in fact it usually sounds bad. Duke Le Jeune of AudioKinesis tunes his Thundrchild cabs to -3dB at the second fundamental, usually 62Hz for the 15" and 82Hz for the 12s. While that may be a bit extreme, @Passinwind of the parish over the pond loves his AK cabinet. Very few current or classic cabs can reproduce the fundamentals of 4 of 5 strings so it is sensible to HPF at any frequency the cab cannot really reproduce. My minimum would be 35Hz at 12dB/Oct but anything up to 50 makes little difference to the sound.

I cannot agree more. The area below the fundamental is not musical at all and most of our sound comes from the 2nd harmonic upwards. A simple hearing test will prove this. If anyone can get to grips with WinISD, you can apply a filter ans see how little difference an HPF make to the response of the bass sound when modelling a cabinet/driver.

These cabs will appeal to some like Harley’s appeal to many well heeled motorcyclists. Good luck to Barefaced if they can sell a few.

This is because the strings have cooled since tuning. When you play, the movement of the strings causes the string to warm up. As the strings warm, they expand and go flat, tune them up and leave them for awhile and tuning will be sharp. You should always tune your bass after playing it for a few minutes. I just strum all four strings like a maniac for five minutes. I learnt this from a tip on the Fender Website.

We have not gigged for a while, one of our guitarists had a heart attack a couple of month ago and we had to cancel some gigs. We did one gig as a 4 piece that went quite well. This weekend we are supposed to be playing as a 5 again. The venue is one where we have struggled to hear each other in the past. Only vocals go through the PA and as the guitards are on either side of the stage and this stage is wide. I have pushed to go IEM or at least get a better monitoring system but there are two dinosaurs in the band. The singer is one and he is the youngest. My last attempt at suggesting IEMs was met with "I hate them and will never use them". The guitarist that had the heart attack has commented more than once that he has never seen anyone with more leeds, meaning why have I go so many? Of course they all turn to me when I have an Allen and Heath CQ20 and I love it, it is more than enough to put all of us through the PA and have a mono monitor mix each. I also have enough speakers including some active subs. That stays in the car as a back-up though I usually try hard to get the best from what we have but this gig I am letting them all get on with it.

Yes I have a couple of the Classic DIs and they have been great. Very versatile.

It varies by venue. some want 2 x 45 mins some want 2 x 60 mins. We have enough to play for about 3.5 hours. covering rock and pop from the 60s and 70s.

Yes the only problem with the wide dispersion and being able to hear yourself more clearly is that you may think you are too loud. The first time I used mine I was told to turn up during soundcheck.

Oh yes. When I started out as an electronic test engineer/technician, that is a strategy you learn very quickly. One other point, if your speakers are active and include DSP, try to set them as flat as possible. There is no point trying to EQ out a peak or trough that is dialled into the FoH speakers. Mic technique. Our lead guitarist can really sing but its like he has had a row with his mic. Never closer than 15cm/6in, we often have feedback issues with his mic (Behringer XM8500).

I have the CQ20 and I found that its best to set the gain via auto and then turn it off once set.

excuse my ignorance but what is a JMJ? I came up with Just Made Jam but it lacks a little in the context department

Very nice spec for a digital system and under 2mS latency/delay.

Well this is a can of worms. There are a few options but some are better than others. 1. UHF The better systems will be form the usual suspects, avoid anything on the 863-865MHz band. It is too crowded and you will get interference. Go for a Channel 38 or Channel 65 system. The drawback to Ch38/68 is that you will need a licence at £75 per year and they re generally more expensive. 2. Digital. The main options are 2.8GHz and 5GHz. These are also used for Wifi and the 2.8GHz is also shared with Bluetooth. Also be aware that there will be a delay/latency. The cheaper the system the longer the delay. These band are both licence free. 3. UHF 600Mhz. There are many systems on AliExpress that use the 500-600 MHz bands but these are illegal for use in the UK although legal in the USA. I am sure others will chip in, just wait a short while.
