Bass thru PA problem

Recommended Posts

Right not sure how to describe the problem . . . .

I have my bass D.I'd into our PA as well as the rest of the band

The problem is when I play it sounds as though my backline is fighting with the PA
and I sound a little out of tune too (I'm not i've checked) !

Turning my backline down helps but then I cant hear myself as well.

Any ideas?

Check the desk to make sure the is no Fx like chorus leaking into you bass channel.

Some room can sound out of tune, there is an explanation for this but it is a bit long winded, try moving your cab about.

If it is at every venue then there is a problem.
Is only when you can hear the sound out of the PA or when only when there is a blend of the amp and PA

When you say fighting.... what you mean exactly? your backline not loud enough compared to the pa?

Best described as pulsating backwards and forwards

I'll check the FX too

Probably a combination of phase differences/cancellation and/or room modes (though as already mentioned, make sure there are no FX including reverb on your channel).

You can try reversing the phase of the DI feed (swap pins 2 and 3, or buy a phase-reverser) - the result will either be quieter or louder out front - use whichever is louder.

Try and use your rig to supply all the on-stage monitoring of bass or none (in which case you need a monitor, but you can leave your rig at home).

Try and minimise spill from your rig into mics (tricky...)
