ARCHITECT‘S SPECIFICATION
EW-DX EM 4 Dante rack receiver
The stationary four-channel receiver with switching diversity technology shall be for use with up to four companion transmitters as part of a digital wireless RF transmission system.
The receiver shall operate within the following UHF frequency ranges, with a switching bandwidth of up to 88 MHz: 470.2 – 550 MHz, 520 – 607.8, 606.2 – 693.8 MHz, MHz, 614.2 – 693.8 MHz, 630 – 693.8 MHz, 823.2 – 831.8 MHz, 863.2 – 846.8 MHz, 925.2 – 937.3 MHz, 941.7 – 951.8 MHz, 953.05 – 956.05 MHz, 956.65 – 959.65 MHz,1785.2 – 1799.8 MHz. Different frequency variants shall be available depending on country-specific regulations.
The receiver shall feature Bluetooth® Low Energy (BLE) at a frequency range between 2402 and 2480 MHz for remote controlling the devices via a control App for iOS and Android.
The receiver shall feature an automatic frequency setup function with spectrum scan functionality in order to establish an equidistant frequency grid with 146 channels in standard mode and 293 channels in Link Density Mode.
The audio frequency response shall be between 20 Hz and 20 kHz (-3 dB). Audio total harmonic distortion (THD) shall be ≤ -60 dB for 1 kHz @ -3 dBfs input level. Dynamic range shall be 134 dB. System latency shall be 1.9 ms.
The receiver shall be menu-driven with an OLED display showing the current frequency, channel number, metering of RF level, metering of AF level, lock status, muting function, antenna switching diversity, app connection, gain, audio output level, menu and battery status for each of the two associated transmitters. An auto-lock feature shall be provided to prevent settings from being accidentally altered.
The following settings shall be configurable by function buttons and an encoder for each channel in the menu: frequency, channel name, gain, trim, AF output, low cut, AES 256 encryption, test tone, network settings, integrated antenna booster settings, display brightness, device name, auto setup settings for automatic frequency setup.
For each of the four channels the receiver shall feature a balanced XLR-3M audio output with a maximum output of +18 dBu along with an unbalanced 6.3 mm (¼") audio output with a maximum output of +12 dBu.
For secure transmission the receiver shall feature AES 256 encryption.
The receiver shall provide a walktest mode for monitoring the RF and AF signal status in the location over time.
Tow BNC-type input sockets shall be provided for connecting the antennas. The receiver shall be usable with active
and passive wide range UHF antennas for the entire supported RF spectrum.
Two additional BNC-type output sockets shall be provided for cascading the RF signal to one additional receiver.
A headphone output with headphone volume control shall be provided and shall utilize a 6.3 mm stereo jack socket.
The receiver shall have Ethernet ports (RJ-45) for remote network-based monitoring and control using the Sennheiser Control Cockpit software or the Sennheiser Wireless Systems Manager software.
An automated configuration for the devices and management of system settings shall be available via "Sennheiser Smart Assist".
The receiver shall operate on 90 to 265 V AC, 47 to 63 Hz via included mains cable. The power consumption shall be max. 37 W.
The receiver shall feature a digital audio output through a Dante® interface, which includes up to four RJ-45 ports (Primary and Secondary).
The audio network shall be output separately on all ports or daisy-chained for redundancy or serial connections.
To ensure flexible adaptation to existing network infrastructure, the receiver shall offer various network modes, such as Single Cable, Split, and Redundancy Mode.
The receiver shall have a rugged metal housing; dimensions shall be approximately 483 x 44 x 373 mm (19" x 1.73" x 14.66"). Weight shall be approximately 4560 g (10.1 lbs) without antennas and power supply. Operating temperature shall range from −10 °C to +55 °C (+14 °F to +131 °F).
