i have a tascam 38 1/2in reel to reel but no mixer. it seems hard and/or very expensive to get a mixer that is compatible. it uses rca style jacks and all mixers seem to use xlr or 1/4in. i was thinking of just using adaptors to go from the mics cable direct to the tascam "in". but i don't see any adaptors of this type so i'm thinking this might not work. what is a work-around using more modern less expensive equipment.
