Fan / Box with XLR Returns, 16 Mics & 4 Returns


The 150’ StageMASTER Multipair Audio Snake from Pro Co Sound features 16 mics, 4 returns, and a 150’ (45.72m) cable.

The StageMASTER Stage Snake stagebox is constructed of a steel connector panel chassis and a heavy-duty steel U-channel enclosure designed for shielding and protecting the connectors. The stagebox has a durable black powder-coat finish with white silk-screened channel identification numbers.

The mic inputs are rugged with Neutrik D-Series nylon XLR panel connectors and returns are D-Series nylon XLR-type connectors. The stagebox is wired with SN multipair audio cable to a 4’ (1.21m) fanout with RHC male XLR connectors and RHC female XLR connectors.

The cable is secured to the stagebox with a rugged nylon strain relief. The individual channels of the fan-out are protected with colour-coded irradiated polyolefin shrink tubing for long flex life and easy channel identification. It has a 16 x 4 (mics x returns) fan-to-box configuration and the cable length is 150’ (45.72m).
