Sennheiser EW-DX EM 2 Q1-9 - Digital semi-rack receiver (9.5") with two channels for use with portable Evolution Wireless Digital transmitters, for body and table mount. Extended switching bandwidth of 88 MHz, intermodulation-free operation for up to 293 channels with secure AES-256 encryption and redundant power via Power over Ethernet (PoE).
- Semi-rack digital with two channels (9.5") in a robust metal housing
- Switching bandwidth of up to 88 MHz
- Low transmission latency without wires of 1.9 ms due to Sennheiser's performance audio codec (SePAC)
- Input dynamic range of 134 dB - no need to set the gain on your wireless transmitters at all, thanks to Sennheiser's performance audio codec (SePAC)
- Equidistant spacing of channels for easy allocation of intermodulation-free channels: Standard mode with a spacing of 600 kHz for up to 146 channels; Link Density (LD) mode with a spacing of 300 kHz for up to 293 channels
- Network enabled for extended remote control with Sennheiser Control Cockpit, Wireless System Manager (WSM - Available mid-2023) and third-party media control systems via plug-in
- Power over Ethernet (PoE IEEE 802.3af Class 3)
- Ethernet connectivity (IPv4 and IPv6)
- Secure transmission of confidential content using AES 256 encryption
- The AutoScan function quickly scans your environment and implements frequencies with equidistant channel spacing - even without RF knowledge
- Link Quality Indicator (LQI) showing link quality separately from RF levels
- Remote control via the Smart Assist app via Bluetooth® Low Energy (BLE) at distances of up to 25 m (available late 2023)
- Clear and easy-to-focus user interface, with OLED display, jog wheel navigation and control buttons
- Selective output for headphones with volume control on the front panel
- Extensive menu settings, such as custom frequency list, selectable sync parameter, and walk test
- External power supply 12V/1A
- Worldwide use (specific frequencies are subject to local RF regulations)
