Quick MOTU Question

the motu 828mkII has the option of +4 and -10 for balanced and unbalanced signals in all the channels in the back.. that can replace a DI Box for recording basses, keyboards, etc?

No !

A guitar signal is a hi z signal which is connected via the hi z input on the front of the motu.
If you want to plug guitars directly in to the inputs on the back of the unit they will need di'ed first.

The z stands for impedance which is measured in ohms whereas the +4 and -10 refer to gain which is measured in db

The +4 and -10 refers to the operating levels of processors,fx,mixers etc in terms of audio gain.

Matching + 4 to +4 etc. insures proper gain structure hence better signal to noise ratio/audio quality etc.

Pro gear normally operates at +4 db while prosumer or home studio standard gear normally operates at -10db.

A lot of modern prosumer stuff does give you the choice to switch between both operating levels.

You can plug line level devices like keyboards etc into these inputs in the back of the motu as long as as you match their operating levels.(+4 to +4 -10 to -10 )

However running these through a good preamp first can give a better sound.
