The ATW1311 is a System 10 PRO bundle from Audio-Technica, that comes with 2 x Audio-Technica belt-packs. The System 10 PRO is an excellent and reliable cost-effective solution to multi-wireless setup’s for instruments and microphones. Audio-Technica’s System 10 PRO Rack-Mount digital wireless system provides the same interference-free operation in the 2.4 GHz range (outside TV bands) as the original System 10 wireless system but with expanded features and versatility. The durable half-rack chassis is equipped to house two receiver units that can be operated locally or released from the chassis and mounted remotely (up to 100 meters away) via Ethernet cable. Up to five chassis (10 receiver units) can be linked using the RJ12 cable included with each system, creating a stable, multichannel system with the simultaneous use of up to 10 channels.
