Pkomor Posted June 3, 2010 Share Posted June 3, 2010 (edited) Does anyone here have an aguilar GS112, Do you find that the tweeter on your Gs112 makes a very slight (very quiet) electronicy sounding whistly hiss? (That makes it sound worse than it is!) Its not really bothering me, but I want to make sure its not a dodgy cab! You can only hear it when the tweeter is on (regardless of settings on the amp..) Edit: see further down! Edited June 4, 2010 by Pkomor Quote Link to comment Share on other sites More sharing options...
Musicman20 Posted June 3, 2010 Share Posted June 3, 2010 Hi! What do you mean by hiss? There is a certain 'noise' with nearly all tweeters, especially if you run your treble high and have the tweet on full. My DB212 makes a VERY slight noise near the tweet but you have to really listen for it. Thats with a very similar LM3. Usually I have tweeters on max 1/3...or off.

Its only very slight, only noticeable at quiet practice levels... If its normal im not bothered at all! Quote Link to comment Share on other sites More sharing options...
Musicman20 Posted June 3, 2010 Share Posted June 3, 2010 Hmm Its a Ray with an F500? Do you have you mids/highs boosted a lot on your bass? Quote Link to comment Share on other sites More sharing options...

Its probably nothing, but best to always check Quote Link to comment Share on other sites More sharing options...

Dood Posted June 3, 2010 Share Posted June 3, 2010 Tweeters don't hiss, amplifiers do. What you are probably hearing is just the power amplifier of the F500 idle. It's nothing to worry about and completely normal. ALL amplifiers hiss to an extent and what you are hearing is just being picked up by Aguilar's sensitive tweeter. If you are hearing a noise that is more than *just* hiss, then it might be worth checking the amplifier out, at least with another cab with a tweeter in to see if that does the same. You shouldn't hear whines and whistles if you have nothing connected to the amplifier and all the controls at zero. Quote Link to comment Share on other sites More sharing options...
Pkomor Posted June 4, 2010 Author Share Posted June 4, 2010 Hmm, i'll try and record it so you can see what you think! I cant decide whether is a hiss or a whistle! Quote Link to comment Share on other sites More sharing options...
JTUK Posted June 4, 2010 Share Posted June 4, 2010 I run quite a high end sound and the tweeters are on maybe a third of the way up. I would expect some hiss here but probably from the bass first. If you can't get rid of it, either the attentuator is broken but you'd know that, surely or not something on the cab. I find the horns quite sweet and not as hissy as, say, SWR/Fostex, but then nobody uses them anyway near halfway surely..which is where is really begins to make a noise. So, don't think it is the cab...something else in the chain..? Quote Link to comment Share on other sites More sharing options...
Pkomor Posted June 4, 2010 Author Share Posted June 4, 2010 Yeah, thinking about it, doods comment about the power amp makes sense, You can get rid of it by turning the level of the tweeter right off.. I'll try and record some samples and see what you think! Quote Link to comment Share on other sites More sharing options...

Pkomor Posted June 4, 2010 Author Share Posted June 4, 2010 (edited) Ive not had time to recordings yet, but there is an interesting new development. The amp makes a noise when turning off, its only done it twice, but it doesnt sound right! The noise is like a drop falling into a glass of water, kind of an upwards whistle! (completely different to the whistley hiss!) Any ideas? Do you think i should send it back? Edit: I've just noticed that it only makes this noise if you turn it off soon after turning it on. If you leave it 30 secs before turning it off again its just a small click. Can any other F500 (or F1) owners see if theirs does it too?

Musicman20 Posted June 4, 2010 Share Posted June 4, 2010 The digital amps of the modern day can make quite a funny 'zip' noise when turned off. The TC RH450 does this. Its sounds futuristic; I like it. I tried another RH450 and it was exactly the same. Im pretty sure that virtually all digital amps make a whoosh or zip when then are turned on/off. It may also be your fan powering up or down. Quote Link to comment Share on other sites More sharing options...
Pkomor Posted June 4, 2010 Author Share Posted June 4, 2010 Thats reassuring! Its definitely not the fan, as its coming through the cab quite loudly! If anyone who has one can confirm that theirs does it too, I'd feel alot better! Quote Link to comment Share on other sites More sharing options...
Musicman20 Posted June 4, 2010 Share Posted June 4, 2010 Ah...right. Hmm. Ive not got a digital MB amp, but Ive got the TC. The sound of the RH doesnt go through the cab; its just the actual unit itself I believe. Im pretty sure any F1/F500 owner would be able to sort this out. Put a topic on talkbass....someone over there will answer really quickly Quote Link to comment Share on other sites More sharing options...

Dood Posted June 4, 2010 Share Posted June 4, 2010 Yes, my F1 hissed exactly the same. It is the head - but you will find that some tweeters are able to reproduce those upper frequencies that hiss appears most prominent in better than others, hence why it was more obvious with the Aggie cabs. Their tweeters are very clear sounding. Quote Link to comment Share on other sites More sharing options...
fretmeister Posted June 4, 2010 Share Posted June 4, 2010 Another F1 user here - I'm using a TecAmp S210 and it is the same. So I turned the tweeter off for home use. Don't really need it anyway! Quote Link to comment Share on other sites More sharing options...
