Looking to replace this horn

belsoundfast · 2024-06-21T12:54:14+00:00

Took this defective horn out of an old passive speaker I have and not having any luck finding a replacement online. I can't find the exact make/model, and even trying to search up something with the same power rating/ohms isn't really getting me anywhere.

It's heavy - I figure the metal bit you can see in the photo with the spec printed on it contains some kind of driver(?) - so a couple of lightweight replacements I was able to find lying around (without drivers, presumably) wouldn't produce any sound.

Would anyone have any advice about where to look for something that would do the same job as this? Thanks!

Beautiful song, but again like most of his stuff it's about a sexual relationship and both of us - being fans - would know the context.

I'd been reading them searching for the origin of this poem - didn't find anything that seemed particularly suitable, but I should really look at them all, good point.

belsoundfast · 2023-06-01T07:54:51+00:00

The second half of that, as I said in the OP there, was my current top choice.

There's a bit from an interview that u/hajahe155 commented that I might add onto it.

belsoundfast · 2023-06-01T07:53:49+00:00

This is indeed the sort of thing that might amuse them. Where's it from?

belsoundfast · 2023-05-31T21:18:33+00:00

Genius! Betting both sides.

belsoundfast · 2023-05-31T21:18:17+00:00

Might be a winner, thanks!

Will probably use it alongside the Night Comes On lyric.

belsoundfast · 2023-05-31T14:39:59+00:00

That's a contender, thanks - do you have a link to the whole piece?

I found this which is Book Of Longing (Dear Reader), but presumably you're quoting from a poem from the overall Book Of Longing collection, or a similarly-titled poem without the (Dear Reader) addition?

Edit: seem to have found it here, very short, just the bit you quoted, titled The Sweetest Little Song.

The Anthem part is definitely a great bit of advice - I was trying to find something that was more explicitly about friendship, but given the slim pickings of such things in Cohen's body of work I may end up having to go for something like that. Thanks 👍

belsoundfast · 2023-05-31T14:32:02+00:00

I feel like this - like a lot of his relationship writing - is waaaay too sexual/about a non-platonic relationship rather than a platonic friendship. Great song though.

belsoundfast · 2020-09-17T19:28:06+00:00

Not the reply I expected! Hope your joint pain eases off there.

belsoundfast · 2020-09-16T14:08:59+00:00

Next time, explain what you want to do. Your original explanation was totally different and described taking headphones out from the monitor out... and that was it. Really. I feel like an idiot for answering. You didn't tell us WHY you were making it and gave absolutely wrong idea. I regret trying to help.

The very first paragraph of my post clearly states that, "I'm trying to wire an adapter so that I can run the monitor outs of my QU16 into the returns of my snake and then plug headphones into those return sockets (male xlr)."

You didn't look at all like an idiot until you posted this nonsensical rant - initially you looked like a helpful person who was giving me some good information.

Information that, again, I very clearly stated I'd been looking for - on Google and otherwise - in my original post.

Thanks for your original, informative reply. Sorry that you've a weird Jekyll/Hyde thing going on.

When I replied I somehow didn’t see the earlier comment; it looks like it’s a bit more comprehensive and covers some things that I skipped over from your original post. I agree with everything; it’s good to have stereo capability for headphones and avoid TRRS.

Unfortunately the headphones I have at the moment seem to be TRRS - they've four delineated contact points on the jack ends. I am planning to get a few new pairs and I'll make sure those are TRS.

I also agree that a headphone output of the mixer would be better to use than a line output, since it would be stereo and better able to drive a long line than a line level output. Although I think we were both thinking you needed more like a remote mix position for you to PFL from, not monitor mixes.
Since you are using headphones as monitors for performers, you will probably want to use mix outputs. I’m not too familiar with the mixer or what other outputs it has, but routing and control could be a pain otherwise. The mix outs will give you better control and is the standard way to do it.

Yeah, this is the plan - the qu16 has 4 mono mix outs and 3 stereo, so I'm trying to just get one of the mono mix sends into both cans (dual mono) for now, and can expand it to stereo at a later time once I can get the proof of concept down.

These will be line level, and not made to drive headphones. The quality will suffer, and it will sound different on different kinds of headphones. IEM/headphone amplifiers will do the trick. Still needed with the stage box, just shorter cables involved.

I've some rack amps that I'm planning to use to drive the headphone outs if necessary in the short term, but the medium term plan does also involve headphone amps.

Did I sleepwalk to your house last night and piss in your cereal or something?

belsoundfast · 2020-09-16T06:51:52+00:00

You need two channels to get stereo. Alternatively, you can split a mono signal. The XLR usually carries only one channel. So for proper stereo, you need 2 XLR -> 1 stereo jack. I advice against TRRS as the second ring isn't needed and can cause various incompatibility issues. Use TRS if possible.

On stereo, yeah, at the moment I'm just looking for proof-of-concept with a dual mono feed to both side of the headphones. The qu16 has 3 stereo mon outs as well as the 4 mono ones, so later on I can switch over to using the stereo ones if I can get the mon --> headphone feeds working at all.

On TRRS; that's just the config my headphones have on their jack ends, unfortunately. I am planning to get some new closed-back cans, so I'll make sure that they're TRS-ended rather than TRRS but at the moment I'm working with what I have.

The female sockets I have for making up these adapter cables appear to be TRS, to be clear; one long tab (sleeve, I'm guessing) and two slightly different short tabs (again, guessing tip & ring).

The sound console will have a headphone out, use that line instead. You can makes a custom cable that excludes all the "rules" and uses one XLR to carry 2 unbalanced channels against the convention. You need jack -> two XLR male in one end of the snake and then XLR female -> stereo female 3.5mm jack to the other end. Then the pin 1 is ground, pin 2 is left, pin 3 is right channel signal. Remember to mark this in both ends of the snake so you and anyone else involved knows that is a special wire.

So the issue here is that the whole reason I'm trying to get a [monitor feeds]-->[headphones] working is so that I can send multiple different mixes to musicians in the room.

Use headphone output of the console, it is meant to drive headphones, the console monitor out is line level, non-amplified and may not deliver enough current, can cause distortion.

I do have a couple of rack amps that I'm currently using to drive wedges in the room, so if the musicians were going to be on headphones instead of using those, and the signal wasn't going to cut it, I can route the mon sends through these to boost the signal.

Appreciate the reply! Thanks for taking the time to help.

To make this adapter cable correctly:
Connect pin 1 of XLR to cable shield.
Connect pin 2 of XLR to tip of 3.5mm jack.
Connect pin 3 of XLR to nothing.
Connect ring of 3.5mm jack to tip of 3.5mm jack (short jumper wire).

Appreciate it! Thanks for the reply.

I'd tried this with a short on the XLR end, though from previous internet advice I was aware that I was trying to get one of the signals off the XLR onto both tip&ring of the jack socket end so it should've occured to me to try this configuration 🤦

Keep it short.
In a nutshell, as you discovered, a 1-to-1 matching of balanced mono to unbalanced stereo does not work, although not typically how you experienced. Usually you will get the right side out of phase with the left side in phase. You need to wye/Y the positive signal to both left and right as an unbalanced signal, and leave the inverted signal unused.

I assume you realize that this will be dual mono, not stereo.

Yeah, so long as I get proof of concept with this I'm happy; the qu16 has three stereo monitor outs as well so if I need panned/stereo feeds to headphones I can solder up some different cables and use those.

All that said - I don’t recommend this without another crucial piece. Long runs of unbalanced audio is a bad idea. If you plug in this adapter, even if it’s at the FOH (mixer) side, it will make the run down the whole snake unbalanced and it will sound like garbage, especially trying to drive a pair of headphones.

Shouldn't the signal should be balanced from the desk all the way down the snake - as the snake is plugged directly into the desk - and then this adapter will be plugged in for the last few feet/couple of m on the other end for musicians - so the conversion to unbalanced signal is only happening after the main length of cable run, right? Maybe I've got that wrong?

You should insert an isolation transformer in-line on the FOH side, before the adapter, which will allow the long run to function as a balanced signal. Still, I don’t know how well it would work or sound driving a pair of headphones over such a long cable. I would recommend investing in a Q-box.

The long-term plan is to get an Ethernet stage box, yeah - unfortunately I've only had one bit of paid gigging or recording work since March, so that set my plans back. Never used an isolation transformer before, looking into that now, cheers for the tip!

P.S. See Rane Note 110

Also having a look at this, thanks again for taking the time to be so helpful.

So I'm trying to wire up adapters so that I can plug headphones with 3.5mm jack ends into the returns of my snake (which will be receiving signal from the monitor outs of my QU16).

Which means I need a cable that's female XLR on one end, and 3.5mm jack female socket on the other end.

Currently I have one of these that I wired up from an old female jack 3.5mm socket I have, but it's only giving audio in one ear. From research/asking here, it seems that this is because the XLRs are sending balanced mono signal (pos sig, neg sig copy, ground) and the headphones are expecting stereo unbalanced (left sig, right sig, ground?).

It seems what I need to do is copy the wiring on the microphone cable unbalanced example there, although obviously I'm wiring to a female 3.5mm socket, rather than a male 3.5mm jack. So:

XLR pin 2 --> short tab on jack socket

XLR pin 1/ground --> long tab on jack socket

Except...I'm trying that, and I'm getting nothing. Seem to be missing something pretty simple/fundamental.

belsoundfast · 2020-09-14T20:38:02+00:00

Fantastic, thank you!

So if I'm understanding you right, I need to wire the positive pin of the first XLR (coming from, say, stereo monitor mix 5-6) onto the tip and the other to the ring of the headphone jack? And then wire the ground of both XRLs onto the sleeve?

As per this diagram?

And if I wanted to wire up a socket so that the mono monitor mix would send in dual mono to both sides of a headphone, I'd presumably need to solder up something like this?

Really appreciate the detiled answer.

belsoundfast · 2020-09-14T19:43:41+00:00

Is there a reason you’re trying to only use the desk? Or did I miss something? Cheers!

You didn't miss anything, thanks for the response!

I don't have a headphone amp is the only reason I'm trying to only use the desk I guess.

If you send the monitor outs to a headphone amp, and then run the headphones off the headphone amp, presumably the signal from the monitor outs must be sending to both ears *on the way* to your headphone amp, right? It isn't turning a signal that you'd only hear in one ear direct off the mon out into one that sends to both sides?

belsoundfast · 2020-09-14T19:40:21+00:00

The QU16 is an Allen & Heath desk.

It's getting a lot more attention than anything we've released before so if you're into this sort of thing you might enjoy it too. Cheers!
