steb Posted March 4, 2012 Share Posted March 4, 2012 Hello everyone. you are all probably overquallified to answer this question but I've been asked to see if something will work. for a pa system they will be using an existing Berhinger UB1002 (picture of inputs http://www.zzounds.com/item--BEHUB1002). input 1 and 2 are used, what cable(s) do I need to connect 3 dynamic XLR microphones to input 3/4 5/6 7/8. The problem is that they are labled left and right. (mono - stereo?) I have no experience in this. what I need though is for the 3 microphones to play through both speakers connected to the mixer - without using input 1 and 2. to me it looks like an male XLR to 2 x 6.35mm jacks but these cables are not available? so it obviously cant be that. I have no experience of this before and I just need to check that the cables will be right first time. the output will be to 2 active speakers. apologies if this is an simple question but any answers that any of you can give will be extremely helpful to me. thank you very much Link to comment Share on other sites More sharing options...
domroz Posted March 4, 2012 Share Posted March 4, 2012 This mixer can only accept two microphone inputs. If inputs 1 and 2 are not currently used for microphones, you could swap these to 3/4 and use 1 and 2 for two microphones straight into the XLR inputs. If this is not suitable for you, I am afraid you need a different mixer with more microphone inputs. Hope this helps Hello everyone. you are all probably overquallified to answer this question but I've been asked to see if something will work. for a pa system they will be using an existing Berhinger UB1002 (picture of inputs http://www.zzounds.com/item--BEHUB1002). input 1 and 2 are used, what cable(s) do I need to connect 3 dynamic XLR microphones to input 3/4 5/6 7/8.

willdoweuk Posted March 4, 2012 Share Posted March 4, 2012 Just connect your 3 mics to the mono channels. Use XLR to jack cables. Should work fine... (mono channels are Left) Link to comment Share on other sites More sharing options...
steb Posted March 4, 2012 Author Share Posted March 4, 2012 Just connect your 3 mics to the mono channels. Use XLR to jack cables. Should work fine... (mono channels are Left) Hi Thank you two for the answers. again silly question but connecting them via XLR to jack into the left mono channel, will this not mean it will only play through the left speaker. in the XLR inputs 1 and 2 there are 2 radio microphone systems, in 3/4 5/6 7/8 they need to connect 3 cheap microphones for karaoke. so by doing what you say will make it go through both speakers, the microphones dont need phantom power or anything special. thanks for your help Link to comment Share on other sites More sharing options...
willdoweuk Posted March 4, 2012 Share Posted March 4, 2012 The channels are labelled as the mono channels which means that they should go to both speakers... Link to comment Share on other sites More sharing options...
david.elsbury Posted March 4, 2012 Share Posted March 4, 2012 The first 2 channels have microphone preamps, which bring the low levels that microphones output up to line level, which the mixer will output. The remaining channels don't have these preamps, so it's a bit hit and miss as to if they will be loud enough. By plugging a single jack into the Left/Mono input on the channels, the mixer will route the signal to both the Left and Right busses.

Ok thats good to know it should work thank you very much for your answer and help. I tried hours of googling and came across here so I thought I would ask. thanks again.

David thank you! so would it be better to look for a mixer with 5 of those XLR inputs? to be on the safe side. Link to comment Share on other sites More sharing options...
david.elsbury Posted March 4, 2012 Share Posted March 4, 2012 Yep definitely. With many small mixers the next step up will be 8 XLR inputs, which would be plenty for your needs. Link to comment Share on other sites More sharing options...
MarkPAman Posted March 4, 2012 Share Posted March 4, 2012 Yes it would. Though 5 is an unusual number and you'll have much more luck looking for a desk with 6 or 8 mic inputs;) Link to comment Share on other sites More sharing options...
steb Posted March 4, 2012 Author Share Posted March 4, 2012 Yep definitely. With many small mixers the next step up will be 8 XLR inputs, which would be plenty for your needs. hi Thank you again for the help. I have seen this mixer now - http://www.studiospares.com/mixers-analogue/behringer-xenyx-1202/invt/380720/ it says it has 4 mix preamps. I will check tomorrow if we can cut 3 microphones down to 2. this should then work? so replace whats in the current mixer (1 and 2) into 1 and 2. and add 2 more handheld dynamic XLR microphones to 3 and 4? thanks for your help. I want to be on the safe side to check it will work so its great to get advice from people. thank you or could any of you suggest a desk with 6 or 8 for <£100 price range? if not the above will be suitable?

dosxuk Posted March 4, 2012 Share Posted March 4, 2012 Do the radio mic rxs have line level outputs - many do. If so (and you can drop to two cabled mics), you can swap the radios to 3/4 + 5/6 and put the cabled ones on 1 and 2. Link to comment Share on other sites More sharing options...
alexadamson Posted March 4, 2012 Share Posted March 4, 2012 It's worth noting that on the pic of the original mixer that channels 3/4, 5/6 7/8 are line inputs with no gain control, so connecting the mic's to the mono input would NOT work. Like mentioned if the radio mic receivers have line outputs, then these would work in any of the inputs. On the second mixer you could connect the 3 dynamic miss to inputs 1, 2 & 3, and then the two radio RX to channels 5 and 7 via a jack cable. If you can get together another £33 then this mixer would also do everything you need, plus 1 additional mic input and two stereo inputs for cd's / iPod etc... Hope this helps...

Bobbsy Posted March 4, 2012 Share Posted March 4, 2012 The channels are labelled as the mono channels which means that they should go to both speakers... NO! NO! NO! Please don't give bad advice if you don't understand things. Inputs 1 and 2 have mic pre amps. The output of a microphone is between 40 and 60dB lower than a line level device like a keyboard or CD player. Inputs 3/4 and 5/6 are for line level sources and a microphone will be way too quiet to give any meaningful input level. The "mono" designation is purely for line level devices with only a single output (like some keyboards); they're not for mic level signals. To the OP...if you need more than two mics, I'm afraid you need a different mixer. This one could be made to work with external pre amps between the mics and inputs 3/4/5/6 but, frankly, a specialist pre amp would be more expensive than a bigger Behringer mixer.

willdoweuk Posted March 4, 2012 Share Posted March 4, 2012 Well I do apologise.My answer was based on the fact that I have the very mixer sitting next to me, and when I plugged in a microphone to the left channel of one of the grouped inputs, I got a perfectly usable sound. But hey, you're the expert. Link to comment Share on other sites More sharing options...
paulears Posted March 4, 2012 Share Posted March 4, 2012 Well - I plugged a mic via a 3 pin XLR to 1/4" jack, wired unbalanced into the line input (which the manual clearly states is usable for +4/-10dB levels - as in line level), and if I turn the level up full so it hisses like the devil, I can hear my voice. As to it being usable, I don't think so. The mixer is clearly marketed as a TWO channel mic pre-amp mixer. The other inputs are designated line level - so I simply can't agree with you. You must have a very strange version of the mixer - because mine has nowhere near enough gain to allow the line level inputs to be effective on a mic unless you shout straight into the end of the end of the 57 I used, just to check what you say. Looking at Bobbsy's profile next to yours, one of you is an expert absolutely! If your mixer has magic line inputs, I'd keep it very safe, because it's special!
