Bluetooth Adapter for ARQ AR-48 / LiveTrak L-20 / H3-VR\n\nAn optional BTA-1 Bluetooth adapter lets you use the AR-48c Ring Controller wirelessly during live performances. Use the Ring for wireless control of all your MIDI instruments and devices connected to your computer—samplers, synths, and drum machines, as well as MIDI-enabled effects processors.\n\nThe BTA-1 can also be used with the LiveTrak L-20. It offers wireless control via a free iOS mobile app featuring most onboard functions, including Fader Levels and Modes, Scenes, EQ, EFX sends, returns, parameters, and more.\n\nAdditionally, the BTA-1 helps you stay out of the shot when recording 360-audio on the H3-VR Handy Recorder. In conjunction with the BTA-1, the H3 Control App lets you remotely access transport controls, level settings, and metadata notes right from your iOS device.\n\nCommunication at up to 10 meters is possible in an unobstructed indoor space with BTA-1 units.
