View Full Version : Bit of a bummer x 2

Just returned from my regular Indie/Alternative night and a couple of bits tonight to tell you about.

Firstly, I got there and set up the equipment and firstly tested the bass bins going through the Crown XLS802 - Fine. Then put the JBL's through the Peavey CS3000 and noticed that one side wasn't working properly. It sounded as if there was just music coming out of the tweeter on the right-hand side. My first thought was "Oh ****, I've blown my speaker". I swapped the speak-on lead and it still did the same. It was absolutely fine when I used it last saturday by the way. On the back of the Peavey are 3 speaker outputs...Left - Bridge - Right. The left-hand speaker was fine so I took the lead out of the right side and put it in the bridge output...everything worked fine so I thought "It's not the speaker, it's the amp"... Am I right? I don't mean to sound too dense but I don't know a lot about that kind of thing, I usually just plug in and play. Now, I tested the lead from the mixer to the amp aswell and that seemed fine but I am going to have to get a new one anyway because......

....during my set tonight I played a few harder tracks (Disturbed, Korn, A Perfect Circle etc..) and it was during 'Bullet in the head' by Rage against the Machine that the punters went loopy. They all surged forward and fell into my stand. It nearly knocked my Denon off but I got it in time. I noticed while I was packing down that the 1/4 plug on the lead that goes from the mixer to the amp had been bent, it was nearly snapped off (luckily I only had one song left)...Anyway, firstly...any suggestions as to what the problem may be? Secondly, and this is for the more local lot...does anyone know of any good repairers? My usual guy has moved premises and I don't know how to get in touch with him as I don't have his number.

Thanks

Gary, I don't want to sart a "you shouldn't have done that" but unless the peavey is different to my amps ( which it may well be) Bridge output is different to a normal channnel, as it's the sum of left and right all shoved into one. Are there any switches on the amp which say like Stereo/Mono/Bridge? I knocked one of mine without noticing, and wondered why turning the right channel down had no effect. :confused: Thats because in mono, the left hand signal is fed to both sides, and only the left volume has control. :doh:
Let's hope it's that simple, but maybe a channel ( or fuse) has in fact gone.

Re mixer cable, as Vectis would undoubtedly say, Backup, Backup, Backup. :D

I have a back up cable mate but I didn't notice it was damaged until I had finished. I've had 4 hours kip as it's been on my mind so I am going to have to get it hooked up soon and try it again.

Just set up the Amp, Speakers and Denon outside, got a few looks from people driving by so I turned it up a notch and played 'Cars' by Gary Numan...Anyway, the most important thing is....everything is OK. No problems. I put a new mixer to amp lead on and tested each channel etc and speaker lead and it's working as it should.

By the way, on the back of the Peavey there is a switch but that hadn't been touched. Thanks for the information anyway.

Glad you got everything sorted Gary. At least you can have a good nights sleep now and it's off your mind!

It wasn't a dig! :( ( Welll, only a gentle one. ;) :D )

Been there, done that. :D :D Glad to hear it's fine.

I'd guess Peavey make the switch harder to move accidentally than our inscrutable friends. ;) ;) :D

Excalibur - If you were having a dig mate, I didn't notice so no worries honestly.

On the back of the Peavey, there are a number of different outputs. There is a kind of switch there which I guess you can only move with a screwdriver. It says Mono and Bridge and there is another one that has DDT or something. I've always left them as they are when I got the amp.

I had a similiar problem on a different make of amp that the switch on the back had either got moved somehow from the stereo to bridged, probably when putting in the speaker cables. Another time one side went and it was a bad speakon plug that had shook loose in the socket of a bass bin.

Glad you got it sorted. Its a bit of a panic when it happens on the night though.
