Holy poo poo, someone just put a Beolab 2 subwoofer up for sale for ~$75, because it's a 100V model for the Japanese market. AFAIK, there's an internal jumper for selecting the input voltage. I am furiously trying to get in contact with the dude right now.

Beolab 2s usually go for around ~$1500 second-hand :stare:

I can't remember ever being inside a Lab 2 as they've always been solid as hell in terms of not blowing up at high SPL so I can't help you on this one. Maybe give your local store a call? They can have a chat with Struer and confirm.

Google just released the audio-only Chromecast: https://www.google.com/chromecast/speakers/



So if you have a stereo or some active speakers with no built-in streaming, and/or you're tired of the limitations of Bluetooth, DLNA, Internet radios etc., hopefully this will be a better solution.

I know there is stuff like the Joydrone out there, which can turn the old-style stick-shaped Chromecast into an audio-only device, but that seems to be a limited-availability thing only for Kickstarter backers. This is a lot more slick (very high WAF), and also finally supports 5GHz wifi.

I've just ordered two :)

You can't weatherproof speakers and such any more than you can stop the tides so don't even bother trying to find something. Even the best 'weatherproof' speakers (which are silly expensive) will succumb to nature eventually, sun is very good at destroying the finish on speakers, moisture and dust will make sure your electronics die well before they should and insects and animals take up residence in anything left outdoors.

Get used to hauling kit around to and from storage and setting up speakers as it's genuinely the best option in terms of cost and quality.

If you're wanting loud, forget 5.1, it's a nice thought but complicates matters immensely considering it's an outdoor setup. A solid 2.1 setup is your best bet and you can spend the cash you save on better speakers and amps, and a limiter because someone will inevitably smash the gains up and kill your speakers in short order.

A list of stuff you'll require:

Power distribution
A mixer (can be a small 8 channel job)
EQ
Limiting
Amplification
Speakers
Cabling

What sort of crowds are you looking to play to and just how loud do you need to go as the higher both of these, the more money you need to spend on speakers and amplification. If you want 5.1 then multiply that number by at least 2 and add on $500 for a processor/receiver with pre-outs.

Unless you go the route of just using a big set of floorstanders outside along with an AV receiver there's actually quite a lot to think about.


Here's 3/4 of my PA setup in the garden of my old house. The subs have been stored in a damp garage since last winter, the finish on them is Tuff Cab which is a UK version of Duratex. As you can see they look a little lovely and they were full of spiders when I pulled them out. And this was from being under cover but in a damp place. Water will straight gently caress your poo poo. They work perfectly but I obviously can't see what damage has been done inside so at some point they may crap out on me or just unleash a billion spiders upon my new garage.



If you're going to move them about but know exactly where you're going to be 'installing' them every time I'd look at creating some form of shelter for them so in the event of rain they only take a minimal beating. If this is something you're going to be doing repeatedly then it makes sense to have them as protected as possible.



In terms of electronics that setup above plus a further 2 subs are ran off just this rack. 1000W total for 4 tops and 4 subs but that's down to how silly efficient the designs are.



Samson unit at the top of the rack is my power distribution (PB10, about $90). I have a single mains cable running into a Neutrik Powercon connector (locking for safety) on the back of the rack which feeds this unit and from this, everything else gets power via IEC connectors on the PB10. I will say one thing about this setup and the fact it's in a case that's moved a lot, the IECs get rattled a lot so before you turn everything on make sure each IEC is in place.

Under that is a Behringer DEQ2496 (yellow LCD), this is my EQ and RTA for when I'm putting kit in different rooms, it smooths out the speaker response and makes things sound 'right' and lets you play with the sound so you can tweak it to your liking. These are about $300.

Under that again is a Behringer DEQ 2496 (green LCD), this is what stops my speakers from getting killed if someone turns up the volume. It has limited EQ due to the onboard memory being tiny so is poo poo for that but the limiting on it is fantastic and IMO, essential if you're unable to keep watch of your kit at all times it's in use. These are about $250.

On the subject of EQ/Limiting, DBX do sell an all in one solution that reviews very well. The PA2 for example is $400 and does the job of both the above Behringer units that I own which is a bonus. It'll also RTA but you'll need to buy a measurement mic to do so which I also had to do with the DEQ.


First amp is a Peavey IPR1600 and is wired in to run the tops (smaller speakers) 4 at a time should I need. This has been replaced in the line up by the IPR 2000 and those retail about $400.

Second amp is a big heavy QSC GX5 and this runs the subs, again up to 4 at a time. These are also about $400.


I know you said you have a generator and that's great but note that digital switching amps like the IPR I have above really don't like being used with generators unless said generator has a really stable power output. It may be worth looking at 2nd hand 'old iron' amps which weigh an absolute ton like the QSC I have but are far less fussy about power input.


Add to this a small mixer and a bunch of cabling and you have all you need to run some speakers...


And I'd like to add that this was the best purchase I ever made for moving speakers :v:

So, subwoofer/speaker isolation platforms like the Auralex Subdude and GRAMMA, do they actually deliver on their promises or are they mostly snake oil?

And wouldn't it just be a hell of a lot cheaper to use a couple of layers of EVA foam or one those rubber tiles they use on playgrounds nowadays?

I'm just looking to lessen my neighbours "enjoyment" of my subs, any tips are welcome, apart from turning the volume down, of course :v:

Considering bass wavelengths can be in excess of 45' long, foam ain't gonna do poo poo, all foam does is stop your sub vibrating the surface it sits on but bass frequencies don't give too much of a gently caress about walls, structures or human bodies. This is how in a nice little gig space fairly far away from any buildings we can get a noise complaint from said fairly far away building where the bass was pretty loving loud.

It's also why you can move your sub around your living room to get the best possible output and have a spot in the next room over be far louder than anywhere in the room where the sub is.

If your sub is well built it won't vibrate itself but a sub will make something shake somewhere down the line and if you're unlucky it'll be something in a neighbour's house. There's quite literally gently caress all you can do to prevent it bar turning down, and I just hate the thought of that.

Low frequencies in general are just a complete nightmare.

If you're looking to isolate the sub from the wood floor then yeah, grab some foam but ideally the sub(s) housing itself shouldn't be causing vibrations like that if they're designed properly. You'll still have the sound they kick out cause vibration elsewhere though and it's usually this that causes annoyance with neighbours as their pictures start rattling on the walls for no apparent reason. Finding the resonant frequency of the building is a fun game and I suppose you could dial that out a bit to try and kerb complaints.

Is there a thread for microphone nerds?

Since I got my amp, I thought about getting a simple dynamic XLR mic, and something like the Behringer XM8500 is within a just-playing-around budget.

I also want to get a boom for it on a similar ~£15 budget, but it needs to fit the mic, extend properly from behind my desk between my two monitors, and support some two-axial movement, so it doesn't become a pain. Unfortch, all boom stands look the same, so I'd like to know if there's any cheap one to splurge on with a modicum of quality. (I can always look into pop filters or windscreen later.)

I've used those mics before and they're perfectly fine in terms of quality. For the money, superb...

And a boom mic stand is a boom mic stand really, if it's going to just sit static then you don't really need to piss money away on exotic things, something like this is more than adequate. http://www.gear4music.com/PA-DJ-and-Lighting/Boom-Mic-Stand-by-Gear4music/3GV

Does the mic some with a mic holder, or will I have to buy that separately to plug it into a stand (boom or desktop)?

Trying to keep the accessories to a minimum, and I can’t figure out how exactly it plugs into the different stands, even going by the product photos.

Are stands like that still good, if you’re using a dynamic mic and talk into it from the side? I imagine it trails a bit when you aren’t talking directly into it sitting behind the desk. That’s part of the reason I’m thinking about a(n adjustable) boom mic that can be moved around and doesn’t obstruct my keyboard and stuff.

Mics all come with clips as they're not all one standard size. It'll have a screw adaptor in the bottom of it too as mic stands also vary in thread size at the point where you attach the two.



If you're using a keyboard/mouse/shuffling papers or whatever on the desk then you want the mic off the desk top as noise will get transmitted through the stand into the mic itself. A boom stand would be best practice in making sure you get as little unintentional noise as possible. And while mics like that aren't amazing off axis as long as you're not far off it should be fine. Bear in mind you can normalise your recording if it's just voice to stop the annoying fade in/fade out of you moving about.

If you can't get the mic to clip then your gain structure is wrong somewhere along the line, check the settings on everything!! Mics are usually the one thing that will clip no matter what necessitating you turning down, it's never usually a problem of not loud enough.

All modern mics can be used when phantom power is switched on so it's not an issue if you do try it that way, the mic will just ignore it if it doesn't need it and you'll damage exactly nothing.

Behringer clips are a bit crap in that they're not very pliable, the upside being they're not going to let go of your mic so force that fucker in.

You guys not have silent discos over there? There's events here which have 3 different DJs playing different tunes in a place where you can listen to any of them whenever you want. It's utterly weird as a spectator.

They usually use RF tech though smaller home systems can use Bluetooth/IR...

And you can just plug them into the headphone socket of your TV/receiver so as long as it's getting audio, so will the headphones.

Can I use Over Ear wireless headphones to watch a film, TV, Netflix, Sky, DVD or Blue Ray?

Yes! Just connect the audio output to the transmitter. Many TVs, DVD players and Blue Ray devices have an audio output on the back. This is the best way to connect, but you can also use the headphone output. Check your specific device to make sure it has suitable output audio connections.

Headphones connected in this way can be useful if for example one member of the family enjoys watching TV at a louder volume; or for someone to play an Xbox game without the whole room hearing the sound. They can also be used (with multiple transmitters set up) to enjoy different things in the same room - for example 3 people listening to a film, while someone else listens to the playstation.

That would definitely work but I hate audio latency so much that I'd probably just end up getting a couple of sets of headphones with long cables. 32ms as it claims there is pretty good, you'll notice lipsync issues from about 60ms quite dramatically. I had a thing where some stuff played over my home streaming setup was 100ms ahead or behind and it annoyed the piss out of me until I solved the issue.

Send them a few questions, it's suggesting that it uses aptX low latency which is 32ms but then also states it uses regular old aptX which has a delay of 165ms which is a fair whack and not something you'd want to put up with.

*edit: alternatively watch a few things in VLC and mess with the audio delay to see if it's something you can live with or whether it would gently caress you off.

If you have all the tools you'll require and you want to at least try making speakers then do it.

I've built 9 Bill Fitzmaurice speakers/subs over the past few years and I enjoyed it a lot.

Two quick mic-related questions:

1) I asked about an "add-on" mic (mostly for gaming comms) that I can use with my headphones and folks at the Steam thread recommended the Antlon ModMic; is it still the go-to for this? My house is quite noisy as I live over an avenue, should I go for the uni-directional or the omni? (Guessing the uni, but I'd rather double check).

2) I have an AT2020+ that I have some trouble with. I was trying to use it with the little tripod base it came with, from my desk (~50~60cm away?). Thing is, since I have the aforementioned noise issue I need to keep the gain down or it will pick up everything coming from the street, someone could be farting in the corner and it'll come across clearly. If I keep the gain down my voice comes across super low and bass-y.

Is there a 'correct' way of using cardioids? Am I using the mic wrong? Most people I see using one on youtube have it set up with a boom arm, really close to their faces, but from time to time I'd see someone using it from the desk and sounding nothing like I do when I try that. I did try lowering the gain and holding the mic right in front of my face and it did make a difference; but I'm not sure if that's because I should have been doing that all along because of the type of mic, or if my particular environment leads to it working better that way.

1) Uni, definitely.

2) A cardioid polar pattern (where it picks up sound from) is like this:



On a handheld mic it rejects more sound from the bottom which would be the side pointed at the audience/stage monitors etc. The AT2020 has the capsule mounted facing the front so it'll reject more of whatever sound comes from behind it, which in your case might be nothing more than your screen. As it's a large diaphragm mic it'll pic up noise easier, they're basically perfect for pick up room ambiance and as you've found out they do that fantastically well. Use it up close and you can bang the gain right down which will stop it picking everything up, they're used as vocal mics for professional recording purposes and if you've ever seen a photo or video of someone doing it they'll be up close (and usually have a pop filter)

I have a DEQ and DCX. Be wary of the DCX as it lacks memory to do all that much adjustment. I seem to recall it flashing memory warnings at me when trying dynamic EQ with more than a couple of options. DCX is pretty much just a compressor/Limiter/crossover, any EQ needs to be done with the DEQ.

I'm fairly sure you can 'upgrade' the memory in a DCX by buying a loving PCMCIA card though.

I was told in this thread that if you have a subwoofer, you need to set the other speakers as "small" in the audio receiver. So what happens when the Audessy setup swiches them to "large, " do I switch it back to small or leave it?

If that's happening then it's likely your sub is sat in a null and Audyssey is getting the mains to pump out frequencies the sub should be doing instead. Either that or your sub isn't doing the business/mic is hosed. Try moving it around and running auto EQ again to see what it does.

The cutoff is around 200 to 300 Hz for the subs in the minidsp if I remember right. What the Audessy does with that I have no idea.

Where do the sub(s) and mains crossover? Ideally you want your sub to cover anything up to ~100hz and the mains everything above that. Getting your sub to cover higher than that means that if it's not placed front and centre between the mains (which is rarely the ideal place for it) you can locate it. Having content 100hz and up coming from places other than in front of you sounds very odd indeed and is why stuff like Bose cubes and subs are trash as they're trying to cover 50-500hz in some cases.
