The Porta Brace SS-A1 Audio Side Slinger is a sleek and compact way to carry 2 and 3-channel mixers, additional battery power and wireless microphones. Thanks to a combination of self-gripping adhesive fastening and small securing straps, your mixer stays exactly where you need it. Space for an NP1, IDX, Anton Bauer battery and other similarly sized batteries is located just below the mixer area. On the top edge is a clear vinyl window that unfolds to protect equipment from rain, snow or dust. There is also plenty of space to accommodate wireless microphones. The shoulder strap is adjustable, well padded and non-slip.
