The SS-A1 Audio Side-Slinger is a neat and trim way to carry a 3 channel mixer, supplemental battery supply and wireless microphones. Using a combination of adhesive backed touch fastener and small cinch straps your mixer stays right where you need it. An area for an NP1, IDX, Anton Bauer, and other similar sized batteries is located just below the mixer area. At the top edge is a clear vinyl window which unfolds to cover the equipment in rain, snow, or blowing dust. There is also plenty of space to accommodate wireless microphones. The shoulder strap is adjustable, nicely padded, and non-slip. Lightweight, comfortable, contoured design made to carry mixers, batteries and microphones.
