Can anyone advise me on what leads and connectors i need to get my jbl4716a and hh v500 power amp up and running -yours confused - CarlOriginally Posted by carl lewis
Just aquired a HH V500 power amp unfortunatley without the fuse - hope to get one shortly - fingers crossed - sorry no pics yet!!!
Blown fuse, huh?
Ummmm, better try it with some cheap speakers first....
If standard, your speakers have Neutrik NL4 MPR, and you'll be connecting to terminals 1+ and 1- of them. I assume you got some cables and connectors with these, since you've already "played" them.
We need to know what kind of connector is on your Roland output (1/4", probably,) and what your amplifer input and output connectors are.
Who's the manufacturer of that amp, and can you link us to a website for it?
there was no fuse in the amp to begin with - i may be on a loser - 6.3A (T) - is this right ?Blown fuse, huh?
Ummmm, better try it with some cheap speakers first....
It should say on the amp or in the manual what fuse is required. You're 240V, right? 6.3A would be the fuse size, yes, if that's what it says for 240V. That's 6.3 Amps.
Aint got the leads yet - borrowed one to play with - neutrik / jack - wrong lead - the info on the amp is male xlrs x2 out to neutrik x2 - roland is standard jack // i have two in puts on jbl do i need x2 xlr to neutrik x2 - the amp is dual channell both stereo.......
No, the two Neutrik jacks on the speaker (you only got one?) are wired together, so as to allow several speakers to be daisy-chained on one channel. Look at the diagram in the tech sheet I posted in the beginning of this thread.
You're gonna have to buy or make speaker cable(s) Neutrik-Neutrik. The end at the speaker is male, I think. If the one on the output of the amp is the opposite, you'll have to get a cable male to female (M/F). You're not being entirely clear here. Are the HH (whatever that is, Hafler?) speaker outputs Neutrik or XLR?
Regarding the input, your amp output is unbalanced 1/4" phone jack, sounds like, and probably mono. The cable will be 1/4" to balanced XLR. You need the manual for that power amp. Sounds like, for starters, you'll be using only one channel.
Just reviewing, you originally said you got a pair of the speakers. So, you'll be running that power amp in dual mono mode, if that's available. Your mono signal will go into one of the inputs. There should be a switch to feed it to both channels of the amp. Then, you'll hook one of your speakers to each of the amp output chanels.
This your amp? http://www.gbaudio.co.uk/data/v500.htm
The limited specs in the link I posted indicate that binding post speaker outputs are available there, so hooking the speakers will be easier. You'll connect bare wire ends to the binding posts, with Neutrik connectors going to the speakers on the other end. Two speaker cables, two Neutiks. The connection is to pins 1+ and 1- of the Neutriks (see 4716A Tech Sheet) . Pay attention to polarity so you get both speakers wired the same. If you want to use the XLR connection instead of the binding posts, you're gonna have to get the manual to figure out which pins provide the output, i.e., how they are wired. Again, get a copy of the manual somewhere so you know what's going on here.
While the daisy-chain approach you suggest will work, it'll only use one channel of the power amp. The better approach is to find out how that amp can be used in dual mono mode so that you can connect one speaker to each channel and use them both from the same mono source. If there's no dual mono mode on that amp, you can obtain a "Y" cable to connect your single Roland output to both of the inputs simultaneously. Talk to your pro audio dealer there about cabling, and GET THE MANUAL.
Regarding the inputs, I see you have 1/4" TRS available in addition to XLR inputs. Most pro amps will accept unbalanced 1/4" TS plugs at their balanced inputs. The sleeve automatically grounds one of the differential inputs. If that's the case, connecting the input can be done with a guitar cord or other shielded cable having standard 1/4" plugs on both ends. Ultimately, you'll want pro cables to do this, though, whether you use the XLR or the 1/4" connector. Here again, you should consult the amp manual for input wiring recommendations.
Maybe these will help.
You said trashed speakers. They look pretty nice, actually. Do your messin' with figuring out how to hook up the amp, and whether the amp works with some cheap speakers first, please. Listen to the Zilchster on this. We BOTH gonna be plenty bent if whatever blew that fuse also smokes your JBL's.
Ultimately, I don't think your neighbors are gonna be very happy about this.
Heh, heh....
Well Zilch - I think ive got it now - I will try with binding post method first - Your A Star....................I WILL use the old speakers for testing .... just waiting for fuse to arrive in morning ... but the bad news is I have operation on hand tomorrow and will be out of service for a month......Nevermind ...Ill keep you informed of progress ..Again Many Thanks...Carl
O.K., glad to help. Playin' guitar will be good therapy, probably. Get the surgeon to prescribe it.
Play good now, and come back here to tell us how it all works out....
Hi - Hand op went fine - amp did not work - just died of old age i guess - second amp failed - got a friend in town whos a DJ - he s gonna run them out for me at the venue before the gig - hes got a nice jbl venue system - not sure what - that will be Thursday night - I will speak again then - Cheers!!!
Hi again, Carl.
Good deal, the surgery went well!
You finding these amps at the curb, are you?
A decent tech can probably make 'em work for you.
Please put your location in your profile here so we can see what town that is....
Hi Zilch.....Cant open profile - Im in Minehead , Somerset , England , UK...Nearest place to a metropolis would be Taunton or Exeter or Bristol....
