    EM 3732 COM-II N


    High-end receiver with up to 184 MHz switching bandwidth. Output for direct connection to digital mixing consoles. Antenna splitter for daisy-chaining up to 8 devices. Remote controllable via "Wireless Systems Manager".

    The EM 3731/3732-II series is characterized by high transmission reliability, exceptional audio quality and simple operation. A switching bandwidth of up to 184 MHz, more than double that of its predecessors, combined with a range of connection options guarantee optimal flexibility for daily use. The integrated Ethernet connection means that the receivers can be linked into any network. The AES3/EBU digital audio interface facilitates a direct connection to digital mixing consoles. Sennheiser's "Wireless Systems Manager" (WSM) software allows you to monitor and control all receiver operating statuses remotely. In addition, this versatile software now lets you reset the channel allocation at any time and store it as a "Scene". A new innovative WSM feature for multi-channel operation is the immediate identification of the channel allocated to each receiver at the press of a button. A high-contrast display and intuitive user interface complete the scope of features of this high-quality receiver. The EM 3732-II is available in L, N and P frequency variants.
