My first setup comprised a Sennheisser G3 system going into a Headway EDB-1 (discontinued) preamp for EQ. After discovering that the allowed wireless frequencies in Denmark was not allowed within the UK, I ditched the Sennheisser (but I would like to be wireless so I am searching for a system)....
The hardwired setup was then made up of the Headway preamp plus a Behringer micropower PS400 providing 48v phantom, as the Headway only provides 18v.
Of course this was not ideal (too many boxes) and I have been looking for a compact pedal style mic preamp with EQ.
That was when I discovered the Zoom A3. It has a pickup input, with settings for flat, magnetic and piezo PU and a 48v phantom powered mic input and it has 3 band graphic EQ plus 2 FX processors with 40 selectable FX.
The Zoom A3 is made for guitar, so it has got a body modeling feature I will not be using, but the rest makes up for a versatile pedal.
For last gigs I have been trying it out and must say it looks/sounds promising. I will have to get more into the setup and handling, so stay tuned for an upcoming article on that.
At the moment the Zoom is set up to provide preamp for the mic and parametric EQ along with the 3 bands of graphic EQ (hardware buttons) on top of that I have a hall reverb and I think it sounds nice through my AER alpha amp, but further tweaking needed. (I am always tweaking ;) )
