The SpeechLine Digital Wireless SL Rack Receiver DW-4-US from Sennheiser is an easy-to-integrate wireless receiver for the SpeechLine Digital Wireless System. It features an OLED display for easy setup and operation and can be used when paired with a wireless transmitter and microphone (sold separately) for applications such as lectures, meetings, and more.
With secure 256-bit AES encryption, the receiver has bi-directional communication, which allows all settings from the mobile transmitter to be adjusted from the receiver. In addition, the automatic frequency and interference management provides convenient and reliable operation, thanks to the easy-to-handle pairing process.
Finally, via network integration all settings and statuses are accessible from AMX/Crestron media-control protocols and the dedicated Sennheiser Control Cockpit software. The antennas can be either back or front mounted. A power supply is also included.
