AudiBox Series Single Channel Transformer Isolated Signal Combiner, 2 Inputs, 1 Output

The ISO-Combiner is a new transformer isolated combiner for the Audibox range of Pro Audio tools and problem solvers. It is ideal for use in applications where two sources have to be combined into one silently and easily.

A pair of transformer balanced female XLR inputs combine to deliver a single transformer isolated male XLR output in this essential audio package.

Available in Single Channel or Double Header format. The heavy duty all-steel chassis is finished in attractive matt textured powdercoat, with hardwearing epoxy screen printing and slip resistant rubber pads.

The ISO Combiner is a totally passive device with no power requirements, making it a universal problem solver.

Security features include Kensington-type computer lock slot and optional bracket kit for under-table mounting.
