Bass -> unpowered mixer -> headphones?

Here is what I want to do:

Bass (passive) -> Unpowred Mixer (Line In) -> Headphones

Will I get a decent signal through the headphones (assume decent headphones)?
(Do I need a powered mixer? DI? Something else?)

This mixer has a headphone out (if that means anything):

I am new to the whole mixer thing. I read in a review of a product somewhere that they did something like this, but no details were given.

I don't want to get a headphone amp because I could also use the mixer as a mixer if needed sometime down the road.

Thank You.
 
"Powered" mixers are ones that are designed to directly drive speakers. They have a stereo power amp built in. It has nothing to do with headphones. In something like 90% of cases, what you're describing with a regular mixer is just fine. Most are designed to be able to take unbalanced input on at least a few of their channels, and most will have enough gain on those channels to be used as a bass preamp into the mixer, giving you decent levels in the headphones. You just have to avoid the other (something like) 10% of mixers that do not have preamps on their channels with unbalanced inputs. Even if you do get one of those though, all you'd need is a simple DI box to make your bass signal suitable for balanced (mic) inputs.

Thanks, this helps a lot! It helps to know what powered/unpowered really means, my translation was powered = more expensive.

So I'm off to read mixer manuals to find one that will work!
 
Honestly, that's my preferred setup for most rehearsals. Excessive volume masks most of the problems that I'd like to hear in rehearsal, & taking the amps completely out of the equation gives us a chance to hear everything. I'm sure it sounds weird to bystanders, being able to hear nothing but drums & vocals. I use a DI into a balanced mic. input. I always carry a DI with me, at least whenever I have a bass. Everybody does that, don't they?????
