Hi everybody, I am the on-stage engineer for my band and I would like to probe your minds for some advice please! We have an M-Audio Projectmix I/O optically connected to an 8 in/8 out Behringer Ultragain ADA8000. In addition to this we also have a 4 x stereo channel headphone amp for on stage in-ear monitoring. The equipment is configured for a live band setup utilising Ableton Live for backing track and track automation/FX purposes. We have 7 inputs plugged into the Projectmix direct from the guys on stage (2 x Stereo Guitar, 1 x Stereo Drum Machine and 1 x Mono Bass). The main vox and 2 x backing vox go direct to FOH, then the FOH engineer sends me back a return on an auxillary channel which I use to feed into the backing singers in-ear monitors (powered by the headphone amp). Overall I am controlling 4 seperate monitor mixes plus the main instrumental mix which gets sent to FOH as a stereo signal. The reason it's all set up this way is because I am on stage, not FOH, so I cannot monitor the vocal levels in relation to the rest of the music. As the sound levels from the instruments are fairly consistent, it makes sense to allow the FOH engineers full control of the vox and the mix between the vox and the stereo feed of the music. This makes sure the FOH engineer is always able to control any mic feedback issues. However, we would like to give the FOH full control of the whole mix - but only after is has been processed within Ableton. At the moment, the equipment we have is limited to 12 outputs (4 on the Projectmix and 8 on the ADA8000). These are all currently used in the following way: Projectmix output 1/2: Main stereo output to FOH Projectmix output 3/4: Bass heavy monitor mix for drummers bass-shaker unit (shakes the stool so drummer can 'feel' the beat) ADA8000 Outputs 1/2, 3/4, 5/6, 7/8: Individual in-ear monitor mixes for the guys on stage What I want to do is expand our total outputs to 24 so I can actually send each instrument channel to FOH *AFTER* it has been processed with Ableton (very important!) and this is where I am having difficulty, because I know how the sound should be routed, I'm just unsure of the best way to acheive it. The most direct solution would be to find a 24 channel output digital AD/DA converter with mic preamps. This unit would also need to be able to handle ADAT optical in/out so it can be synced to the Projectmix. Does anyone know of a unit that meets these requirements? The alternative would be to slave another couple of ADA8000's, but I don't think it's possible. Again, can anyone clarify if there is a way to do this? I hope there is a genius amongst you that can help! Thanks!
