hehe, I am listening to Meshuggah right now. That's pretty cool. Do you ever have other cases where you are trying to connect low and high-impedance signals with each other?
Keyboards are usually the only thing that screw me up when recording our band live. Sometimes I've gone direct to the board from the keyboard amplifier 'Pre-out' (like on a Peavy Keyboard combo amp), and had major problems controllling levels. The DI helps a lot to match impedence, and seems to solve the level problem.
Also have a Behringer Ultra GI-100. I have yet to try this with my vintage Fender Bassman, but suposedly you can connect it between your amplifier's output and your speaker cabinet; it taps the amplified signal of your amp direct to the board, but your speaker is still connected. I worry a little bit about matching the output impedence of the tube amp when trying this though.
We always DI/split the Bass to the PA when playing live.
Just thinking outloud now that perhaps an acoustic electric guitar pre to a DI might not be a bad set-up.
Any source thats a long distance from your board, or high impedence...
Have you noticed any mains hum/nastiness from using channel 4 up the right hand end by the mains switch? Maybe I have a rogue unit but it seems a little prone? How's yours?
Hi Mark, mines the single unit. You must have the 4 channel model.
You think you are getting some power supply hum introduced into Ch4 because thats where the power supply is? Power suppy diodes CAN scream with 60hz noise, so you might be right.
The single unit is battery or phantom powered, so no noise problems from a power supply.

The only thing I DI anyway is Bass guitar, so it would be them three units, listed in order of how often I use them for bass.
And not uncommon, the first one into one of the others.
