connect to high.......

Postby BluesBassPlayer » Sat Sep 19, 2009 5:09 pm

My new 25th Anni, came with a sticker near the input jack,

"Connect to High Impedance Input for Correct Performance".

Would this be the active input mode on my amp? What if my amp doesn't have an active mode?

Does it have an input pad switch? If no then you can just turn down the input gain.

This is what I posted to you over on the EBMM board...


The input impedance and the input pad are separate. On the surface, they would appear to be related, but it just ain't the case.

Don't connect the bass (or any other bass or guitar) to a line level input; a studio signal processor, for example. Your basic bass amp, pad in or out, has a high Z input - or at least it should. A direct box is fine as well. You can also use an unbalanced input to a mic preamp, which is what I use.
