what kind of source level from bass

Hi,
As a beginning bass player,I am wondering what kind of source level my fender mustang with a passive pickup gives out.
My mixer says to use LINE/Mic switch depending upon either a line-level source such as keyboard /audio or microphone/ other mic-level source the source level.
Please help me in the issue. Thnaks.

You'll definitely want some sort of impedance transforming device (i.e. a preamp) in front of your board's input channel with a passive instrument, unless it has a very high input impedance, which is unlikely. The preamp should have a line level output.
 
I have plugged guitars (telecaster, Les Paul, etc.), passive basses, and mics into my 10 year old Mackie 1202 mixer. Works perfectly. Quiet, good EQ, very flexible routing. You don't need a preamp, because in effect each channel is a preamp, especially if you have input trim pots like the Mackie does.

Piezo pickups are another matter.
 
A bass is instrument level, you need some sort of preamp in front of the mixer, most likely, if I understand you correctly. What else are you using? Amps, speakers, etc.

Erm.. A mixing console is actullay a bunch of preamps, albeit Mic preamps generally, but none the less preamps. If the mixer has hi impedence inputs, line level, usually 1/4" jack, inputs that should work. If it does not, simply use a DI box, passive or active (if the mixer has phantom power) and a mic cable. Either way, you should be able to plug an instrument directly into most mixing consoles, with very few exceptions.
