I have a Tenor Risa Solid uke. It has a passive piezo pick-up.
I have started looking at plugging this into various other things like pedals, mixers etc for gigs. Some questions:
Some Instruments offer either a high impedance or "line" level impedance (Z). I think passive has high Z and active tends to have "line" level Z of around 100-200 or 1k Ohm ??? (I guess the pre-amp outputs at "line" level.
Having studied Transmission and Electrical Eng at uni, I don't have a technical problem understanding balanced versus unbalanced and impedance matching. I just don't have any experience choosing or using this stuff - I'm lost.
The main application for this is to play in a band where I need to plug my uke into a mixer.
I don't think I need to worried about "balanced" signals like the XLR because I don't have a long cable run - Might do later in the year at a festival though.
When do I need a DI unit? I think most mixer inputs are line level and I should therefore maybe present a "line" level signal to it?
What happens when I insert an effects pedal in this? Pedals don't tend to mention impedance much.
Or is this a load of rubbish and crack on regardless?
