Connection Diagram

NOTE: Yealink microphones (VCM34) or Bluetooth wireless microphones (CPW90-BT) cannot be used in tandem with the HDL300.

NOTE: The Nureva Aux In / Out connections are single-ended, unbalanced signals with default maximum output signals as given in the table below. Any equipment requiring voltages below these levels may result in clipping, distortion, and in extreme cases, damage to connected systems. Equipment requiring voltages above these levels will not be adequately driven by the HDL300 system’s output signal and may result in quiet / no audio on the channel. Before connecting to the Nureva Connect Module, ensure the third-party device voltage levels are adequate or adjusted properly by additional interfacing hardware.
