Live recording on BR-800

[Krad2004]

Hey dudes. i've got band practice tomorrow and i want to record the session with the built in mic's on my br-800. the only thing is, when i tried before the bass and bass drum over powered the rest of us on the recording and it sounds shocking! lol. ive also tried turning the bass amp down a touch but that didnt work and the bass drum obviously doesnt have a volume know, lol. Does anyone know how i can achieve what i wanna do or if anyone know a sweet setting on the 800 that would be great. 

Thanks guys

Hey dudes, just a quick update. I figured it out.I turned the the low gain to -4 and the low frequency to 100mhz and that worked. Thought I'd tell ya just invade anyone wants to do it one day
