My 'little'PA is an ancient HH MA100 (five input mixer amp) which is ideal for me as a solo multi intrumental vocalist . However for the trio I work with regylarly I add a Folio 4/6 mixer , with BOTH outputs into one channel of the HH . All the Vocal mics go through the Folio (Still one spare mono i/p ) the Interval music minidisc goes through one of the stereo i/ps , and all the instruments go direst into the HH . For larger gigs I have a 350 a side Soundmaster with a 16 channel Peavy mixer .
