"Great Rack Mixer for Pre-Mixing Drums"

Overall: 3.5 out of 5 stars

Verified Customer zZounds has verified that this reviewer made a purchase from us.
I use the 12R to pre-mix my drums and just send a stereo pair to the FOH. I play in a 60's through today band. Not a lot of frills but I love having a great drum sound. I mic 6 drums and 2 overheads so taking up 8 channels on a small board doesn't leave much for the rest of the band.So for about $1500 or so I bought this Alesis 12, (3) DBX Dual Compressors, A Lexicon M300 and DBX 2 x 15 EQ. I take the XLR from the Mics into the 12R, insert Bass, Snare, 2 Toms and 2 Floor Toms into the compressors. I take the snare and go into the reverb unit so I can change my sound from song to song. I use the EQ on the snare and bass to totally dial in the tones. The snare is then run into a stereo channel so I have the dry mix and the wet mix. All these are then mixed into the stereo pair and sent to the FOH board.The one drawback is not having the ability to tweak the levels mid-song, but We don't even use a sound guy...we just soundcheck well and make sure the sound is good. Overall this unit does the job for what I need it to do. We use a Mackie for FOH so the signal isn't really being boosted much by this unit.
