Help ..... need to use the Mixer channels with Stereo line ins for a mono feed ...


Recommended Posts

Posted (edited)

Drummer just added 4 drum triggers so I need 4 extra line inputs (Jack).  It would be handy to use the Stereo Line in Channels - but as a mono line in feed.  Won't work just plugging into the R channel, nor with a splitter I have which splits a single mono Jack into two mono jacks (for left and right channels).  Perhaps the splitter isn't right , but surely there's a way of doing this?  The Mixer is a Mackie Pro16 FX v3?  Anyone know ?

I have a small Mackie anogue mixer, and the stereo input jack sockets are wired so that 1 jack onto the left socket gives you an output on both left and right busses. One jack into the right socket gives you an output on the right bus only. This also works with several other mixers I have used.

Have you tried plugging into the left jack socket only?

As has been said most mixers with stereo inputs should be wired so that only using the left input sends the signals to both the left and right bus.

 

If this is a digital mixer you may need to set this somewhere in the UI.

If that's not an option for your inputs, wondering if something like the Hosa GPP-419 TS Mono Jack - TRS Stereo Jack Adapter | Bax Music (bax-shop.co.uk) might be your answer?

Thanks everyone!  All working now - via Left input or Splitter so all good!  It's not a Mixer issue it's just that the gain is way too low on the feed from the Trigger - live test tomorrow evening ..... 🤞 
Hadn't twigged that the gain adjustment on the channel ONLY adds gain to the MIC input and not the line input (unlike the other mono channels) - now I realise this and have checked it with other sources it's clear it's the trigger output itself that's the problem.

You might want to talk to the drummer about a sub-mixer /drum mixer that they control themselves. If you start to run multiple triggers and mic drums separatelyyou could easily out grow your mixer. It's also a lot to manage if you are mixing and playing bass at the same time. My experience is that drummers take more pride in their sound than any other band member so controlling their own sound and feeding you a stereo mix after they have mixed it themselves might go down well.

Good thought!  Thanks.

We have one Spare Channel left so we may run into problems soon!

How does the Drummer get to know what he sounds like " out front".  Is it just a question of making sure it's ok at sound check and hoping he doesn't crank stuff up during the set?   Or is that just a guitarist problem?  I suppose after sound check we're all pretty hostages to fortune anyway though ..........

I think all my drummers have been really fussy about their sound, more so even than guitarists, and they all have had really good ears, or did before they started drumming 😂 They will usually care much more than you so trusting them is good, though you may need to negotiate if they want something that upsets the band mix. I've never had problems by taking what they say seriously.

 

They/you sort it at rehearsals, we have the odd technical rehearsal where we sort out any PA problems. We put the PA up as far away as possible pointing back at the band and switch off any monitors. I've had drummers taking over an hour to be happy but save the settings (mark with tape on analogue mixers) and that's the mix you take to gigs. If they change things at home then just get them to warn you so you can re-mix. Once you have a stereo feed you just mix it as 'drums'. There are dedicated drum mixers out there and you can use the 'brain' from a set of eDrums to deal with triggers.

I’ve played with and/or been around a good few e-drummers (is that a phrase?) and yeah if they’re geeky enough to go that route, they generally have some sense about them!

 

I’ve found most set the relative levels of the kit on the brain unit to what sounds like the balance you’d get on an acoustic kit and then leave well alone… and let the sound person do their thing. Of course, they could push their master up mid set, but then so can the rest of us!
