Comments about Rolls MX54 3 Channel Battery Powered Stereo Mixer:
For the price - a very good buy for a stop-gap solution out in the field. The only downside I saw was that it takes only mic connections so if a line connection is needed one needs to attach a pad (-20-30 db).
The sound is not great but then for the price one would not expect much better since it serves my needs well without having to spend hundreds more.
