The new model connects up to four pairs of headphones, with unbalanced stereo inputs and independent volume knobs. The product is suitable for group music making, rehearsal rooms, recording and broadcast studios, and language or listening classrooms. A switchable unbalanced input mode accepts the stereo headphone output of another device. Unbalanced mode also allows two 4AMP units to be connected in series to increase the number of headphones.
