Hi ST,

A couple of comments as I run this setup regularly (Mackie ProFX8).

  • Not all mixer 1/4" main outs are balanced TRS, there are still some unbalanced TS-equipped models out there, especially in the entry level realm. Suggest adding a "check your manual" caveat/note. Still not a deal breaker, though, as you can still run unbalanced 25'-30' with no ill effects other than a possible nominal 6dB loss in level from using TS plugs in a TRS jack, depending on how the L1 varieties handle that.
  • Regarding the note under level setting "Adjust the volume of the Third Party Mixer Main Output to the maximum output without distortion. This may be marked as unity or 0 dB."
    • 4dBu is the reference point on most analog consoles, but while that may read 0dB or unity on an analog console main meter, on a digital console meter it will read -18dBFS (dB below Full Scale) in the US, or -20dBFS in the EU. Suggest changing "This may be marked as unity or 0 dB" to something like:
      • This may be marked as unity or 0 dB on analog consoles, or -18dB on digital consoles. Check your mixer manual to be sure.
    • All consoles also have headroom built in and can go up to 12, 18, even 28dBu above the reference level in some cases without distortion (or at least that which you can hear). This additional headroom is designed in to allow the mixer to handle sudden signal spikes without distortion, and the listener should not hear any unless the manufacturer's specified max specified output level is exceeded. Suggest changing "maximum output without distortion" to "reference" or "nominal" output level.

 

Hope this helps,
Jeff

Hi Jeff,

Thanks for the suggestions.

I've added some more information about using unbalanced connections, changed maximum to reference/nominal and added and references to dBu and dBFS settings on output meters.

I plan on buying two  L1 pro32s2 units to run stereo on my d.j./p.a. system.

I currently use an allen heath zed 12 ch. mixer for p.a. to a bose F1 cabinet on the rt. and Lt. of the stage with xls cables to the cabinets from the allen heath mixer.

I also use a D.J. mixer out to a QSC cabinet on each side of the stage for my d.j. & karaoke music.

So i believe in my checking of the L1 SERIES units that they have two different inputs on the control module on the L1 systems, so could i run my allen heath outputs to one input and my d.j. mixer to the other inputs.

I would surely eliminate a lot of extra weight and stage clutter if i am able to do this.

i would like to use the T8 bose mixer but it doesn't have enough channels

Hi Doug,

Welcome to the forum!

That's right, the L1 Pro32 system has two separate input channels with XLR/1/4" connections with individual tone & volume controls. This means you'll be able to connect the stereo left & right outputs from both the A&H Zed mixer and DJ mixer to play simultaneously through the two L1 Pro32s. 

Hope this helps.

Thank you very much for the prompt reply i have already purchased a pair of L1 pro 16 units i feel they would be more than adequate for my musical needs but if i wanted to add 2 more L1 pro 16 units in the future could i daisy chain across to them off of my 2 present units

Hi Doug,

Yep you could! The L1 Pro systems all have an XLR line output that you can use to connect to other speakers.
