Sennheiser EW-DX-835-S Evolution Wireless Digital Handheld System with e83

Designed for ease of use and high scalability, the EW-DX series digital wireless brings Sennheiser's rock-solid performance and signature audio quality to your corporate, academic, or live performance application. The EW-DX 835-S Set includes two handheld transmitters with MMD 834 mic capsules, an EW-DX EM 2 rackmount receiver, and a pair of BA 70 rechargeable batteries. Sennheiser's integrated Auto Scan technology takes the work out of channel management by assigning equidistant channels making better use of the frequency range and avoiding annoying intermodulation interference. The system is controllable via tablets and smartphones (sold separately) using the Smart Assist app. Alternately, WSM (Wireless Systems Manager) and Control Cockpit software (sold separately) offer advanced detailed system overviews of complex networked environments. EW-DX also features Ethernet control ports and AES-256 encryption so you can feel secure transmitting on IT networks. Since the audio is what matters, the system has been engineered with a 134 dB dynamic range, low noise floor, and a latency of only 1.9 ms so you hear everything, on time, as intended. With a 12-hour runtime and support for network-enabled charging (charger sold separately), the EW-DX makes power problems a thing of the past while defining the future of wireless.Sennheiser EW-DX-835-S Includes:EW-DX EM 2 rack receiver2 EW-DX SKM-S handheld transmitters2 MMD 835 microphone modules2 MZQ 1 microphone clamps2 rod antennasPower supply with country adaptersGA 3 rackmount set4 rubber feet2 BA 70 rechargeable battery packsquick guidesafety guidemanufacturer declaration sheetSennheiser EW-DX-835-S Features:2 channel half rack (9.5’)Up to 88 MHz switching bandwidthPoE IEEE 802.3af Class 3Equidistant Channel Spacing: 146 channels in standard mode; 293 channels in Link Density ModeNetwork-enabled for control with Sennheiser ControlCockpit/media control system through a number of 3rd party modulesEthernet connectivity (IPv4 and IPv6)Secure AES 256 encryption10mW RF power with up to 100m/328ft working rangeCharging contacts for in-device charging with CHG 70NProgrammable mute switch on EW-DX SKM-SControl all the transmitter settings directly from handheld microphoneUp to 12 hour runtime with lithium-ion batteriesSennheiser EW-DX-835-S Specifications:SystemAudio link frequency rangesQ1-6 470.2 - 526 MHzR1-6 520 - 576 MHzR4-9 552 - 607.8 MHzS1-7 606.2 - 662 MHzS4-7 630 - 662 MHzS7-10 662 - 693.8 MHzU1/5 823.2 - 831.8 MHz & 863.2 - 864.8 MHzV3-4 925.2 - 937.3 MHzY1-3 1785.2 - 1799.8 MHzBluetooth® Low Energy (BLE) frequency range: 2402 - 2480 MHzAudio frequency response: 20 Hz - 20 kHz (-3 dB) @ 3 dBfsAudio THD: ≤ -60 dB for 1 kHz @ -3 dBfs input levelDynamic range: 134 dBSystem latency: 1.9 msOperating temperature: -10 °C - +55 °C (14 °F - 131 °F)Relative humidity: 5 - 95 % (non-condensing)EW-DX EM 2 (Rack Receiver)Input voltage: 11 - 13 V ? or PoE IEEE 802.3af Class 0 (CAT5e or
