Subwoofer through aux

I have the following as part of my PA.

Alto Live 1604
Alto TSSub18
Alto TS115A

Has anyone tried sending kick drum (floor Tom) and bass guitar to sub through Aux thereby completely eliminating the need to use the standard connection configuration of sending output to sub then through that to tops.

Is it worth it? Has it made a difference to the low end?

  • Hi James,

    Thanks for posting!

    This could work and could be fun to try out, though here are a few things to consider:

    1) Kick and Bass will ideally take up more frequencies than a sub alone could cover (Sub18 only covers up to 125Hz). So, you would still need to send the kick and the bass to the main mix to cover, say the body of the bass, attack of the kick, etc. If you're using a Subgroup to send out the Kick/Bass, just depress the Left/Right buttons above the group fader to send it to the Main output as well.

    2) The Sub is already performing the crossover for you at 80Hz on it's output, so any speakers connected to the sub won't be receiving anything below 80 anyway. Not connecting through the sub would mean that the TS115A would then be receiving those lower frequencies. But, an alternative to that would be to use the EQ on the 1604 to take out the low end.

    3) If you use Aux send 1/2, pre-fader to send the kick/bass out to the sub, this could get you some additional control over the signal being sent to the sub, vs. the signal being sent to the main mix.

    I imagine that sending the signal to the sub individually would provide some additional clarity and breathing room for your mix if done correctly, but it's going to take some tweaking and balancing to get it right. It would be difficult to walk someone through this via a forum post, but if you're confident than I'd say go for it :)

    Let me know if you have any questions!

  • Thanks Corey.

    That is a very good explanation. Sending bass and drums to the sub via Aux will mean missing out on the other frequencies, which as you pointed out will need correction via routing it through the main mix and twiddling around with the EQ.

    We are a small band and our next gig is in a few months time. Worth trying it then.

    Also, could you confirm whether the crossover on the TSSub comes activated? I noted there is a little hole through which you can stick a pin in to turn the crossover on or off. I presume you do not need to touch it unless you aim to disable the crossover.
