Two or four channel receiver for SpeechLine Digital Wireless
Choose product variant


The SpeechLine Multi-Channel Receiver with its 2 or 4 channels is the perfect addition to the SpeechLine series. Thanks to its unobtrusive design, the Multi-Channel Receiver can be installed quickly and easily in any room, whether on the wall or ceiling. The device can be operated with a single network cable, thanks to PoE and Dante. Complex analog audio cabling is a thing of the past. The Multi-Channel Receiver also offers a convenient solution for existing installations. Thanks to an integrated auto mixer and the analog mix output, all audio channels can be used simply as a sum signal. The audio mix is also available digitally via Dante, which allows an extension of the existing setup without exchanging the DSP. Due to the bidirectional communication between receiver and transmitter, all settings of the mobile transmitters can easily be made in the Sennheiser Control Cockpit. The receiver's automatic frequency management eliminates the need for manual frequency settings and the automatic interference management guarantees maximum transmission reliability. The user-friendly pairing function ensures a reliable connection between transmitter and receiver. Network integration also makes it possible to remotely control and monitor the receiver via a media control system (e.g. AMX, Crestron). Due to the integrated antennas, a complex antenna installation is no longer necessary.
