Soundcraft Gigrac Mixer Amp
A very compact mixer-amplifier, ideal for small shows or simple speech applications. There are eight inputs, which can take jack or XLR inputs for instruments or microphones. Four channels can also take stereo sources like phones or laptops.
Controls are simple but powerful, and there is even a built in effects unit for adding reverb etc.
The Gigrac is ideal for novice users, and comes with a full instruction sheet so you'll be up and running in no time at all.
