Re: How Important Is Optimal Gain Structure In A Modern PA System?

Dave Rowles wrote: Sat Dec 14, 2024 4:27 pmAll my amps are set so that I can set my fader to zero mark, gain until I've got enough level, and then eq/compress/gate as needed. Takes me about 15/20 seconds a channel for initial setup, then I'll tweak through the first song.

This!

Re: dbx 223xs set up

Nevertheless, the principle of connecting both channels to the one sub is valid, and it's the way I work very happily with my own 2.1 (RCF) system. Same here. Depending on the venue, the transport I have, and how much I can be bothered, I'll take either one or two subs. A quick listen and it's dead ...

Re: Budget PA for Arts Centre

The channels have no input/peak indicator or volume controls whatsoever, only a universal 'gain' control. So it's impossible to set levels and adjust volume without also affecting the master output (accordingly it's prone to distorting too). The channels have no pan controls either. Honestly I don ...

Re: Budget PA for Arts Centre

The Carlsbro is no use really, it's a mixer/amp combined with passive speakers. The speakers sound bearable but the mixer/amp is atrocious. Can't really salvage the speakers without an amp. What is actually atrocious about the mixer amp? If it's just that it's a classic basic mixer amp with limited ...

Re: Budget PA for Arts Centre

Good finally to have a picture of the place and an indication of what it may actually be used for. What's actually wrong with the existing Carlsbro system? If it sounds OK, but just lacks inputs, there's nothing stopping you getting just a mixer to feed through it. Some wall brackets *safely and ...

Re: HK Linear 5 Sub 1200's not firing.

Glad to hear it. And Hugh's right, it's too easy to forget about the intricacies of speaker cabling with the prevalence of active PAs. And, taking a look at your Lab Gruppen amps, see how channel one's speakon outputs both ch 1 & ch 2 across the Speakon's 4 terminals. The idea is that you can use ...

Re: HK Linear 5 Sub 1200's not firing.

I suspect it's a simple cabling issue. The subs receive their input on 2+/- of the 4 pin Speakon ( https://hkaudio.com/products/linear-sub-1200/ ) You'll very likely be feeding them with 2 core speaker cables connected to pins 1+/- Take the Speakon cable feeding the sub and, at the speaker end, swap ...

Re: Microsoft Surface not passing audio in right side in headphone output

We're not likely to see this presenter again in the foreseeable future - it was a DMA lecture/recital. So, the USB to 3.5mm dongle might not be ideal for our situation. So far, everyone has had either a working 3.5mm socket, or a free USB A port (or an HDMI cable piggybacking on the video stream ...

Re: Microsoft Surface not passing audio in right side in headphone output

3.5mm outputs from various devices are a crapshoot best avoided. At best, they'll sound "OK". At worst, there are a number of issues that can bite. A simple USB audio interface should be part of any engineer's toolkit. The Soundwire solution mentioned is perfectly reasonable, but you'll get decent ...

Re: Allen and Heath QC20B

As I said it is the singer's XR18 but I'm fairly sure it was the internal router we were using so that may explain the problem. That'll be the one. Even Behringer don't recommend using the internal AP other than for domestic use - for which it's really quite acceptable. Having said that I really ...

Just to explain - (plus I think you're right, horses for courses is quite true).

But whichever version you choose, it's powerful, capable, sounds good, and is amazingly affordable. The reality of these cheap lunchbox mixers is really quite exceptional.

Basically [CQ18T is] the same with an OK touch screen, 1/4 " output jacks and a line lump power supply. Yup, quite unattractive, really. Give me XLRs and IECs any day. Personally, I never get the desire for a built-in (and ropey) touchscreen. For the situations I use my lunchbox mixer in, it sits ...

Re: Another buzz question

The simple and pragmatic approach is just always to make sure you carry DIs and isolators, in case you need them. While I'll always use DIs for pro shows, I tend not to for small shows and pub gigs. Things happily get connected up the quick and dirty way which, almost always, works without problems ...

Re: Can I feed Bass Guitar into PA?

My normal response to most of these "can I...?" posts is to try it, start at low level, and increase to show level, using your ears to tell you if there's a problem. Then you will know, in this case, both if the system can accommodate it without strain, and if it sounds acceptable. No-one else can ...

I'm also of the view that this looks like damage, rather than a manufacturing defect, albeit that the design doesn't look too resilient. Given that, based on the original description, this had been in operation for 3.5 years without problems, something has introduced the fault, which is most likely ...
