General DescriptionThe EM 3731/3732-II series is characterized by high transmission reliability, exceptional audio quality and simple operation. A switching bandwidth of up to 184 MHz, more than double that of its predecessors, combined with a range of connection options guarantee optimal flexibility for daily use. The integrated Ethernet connection means that the receivers can be linked into any network. The AES3/EBU digital audio interface facilitates a direct connection to digital mixing consoles. Sennheiser’s „Wireless Systems Manager“ (WSM) software allows you to monitor and control all receiver operating statuses remotely. In addition, this versatile software now lets you reset the channel allocation at any time and store it as a „Scene“. A new innovative WSM feature for multi-channel operation is the immediate identification of the channel allocated to each receiver at the press of a button. A high-contrast display and intuitive user interface complete the scope of features of this high-quality receiver. The EM 3732-II is available in L, N and P frequency variants.FeaturesUp to 184 MHz switching bandwidthDigital AES 3 audio output with external word clock synchronisationIntegrated antenna splitter for daisy-chaining up to eight devicesIntuitive user interface with OLED displayNetwork integration via ethernet for use of the WSM software on Macs and PCsDSP-based HiDyn plus and HDX expanderTransformer balanced audio outputsScanning functionFrequencies adjustable in steps of 5 kHzSquelch setting displayed continouslyCommand audio output ( EM 3732 COM-II only)Delivery IncludesEM 3731-II or EM 3732-II or EM 3732 COM-II3 mains cables (with EU, UK and US plugs)2 BNC antenna cables (50 Ω) for daisy-chaining1 BNC word clock cable (75 Ω) for daisy-chaining4 rubber feet1 RJ 45 ethernet cable2 antennas1 instruction manual1 CD-ROM with the Sennheiser Wireless Systems Manager Software1 frequency tableTechnical DataRF frequency range L: 470 – 638 MHz, N: 614 – 798 MHz, P: 776 – 960 MHzSwitching bandwidth Up to 184 MHzReceiving frequency 6 frequency banks with up to 59 factory-preset frequencies each, 1 frequency bank with up to 60 freely selectable frequencies (tunable in steps of 5 kHz)Adjacent channel rejection typ. 75 dB / +-400 kHz, typ. 80 dB /+-800 kHzSquelch threshold 13 steps (0 … 30 μV)Intermodulation spacing >= 80 dBAntenna connector 2 BNC connectors (50 Ω)Cascadable 2 BNC connectors (50 Ω)Gain 0 dB ±0,5 dB (ref. to antenna input)Compander Sennheiser HiDyn plus emulated by DSP, Latency Frequency response 40…20000 HzNominal deviation +-40 kHzPeak deviation +-56 kHzSignal-to-noise ratio ≥ 118 dB(A) (analogue AF OUT), 140 dB (AES3 audio out)THD, total harmonic distortion ≤ 0,3 %Output voltage +18 dBu to –10 dBu, adjustable in steps of 1 dB (transformer balanced)Audio-XLR connector analogue: XLR-3, digital AES3: XLR-3 Sample Rates: 44.1, 48, 88.2, 96 kHz, 24 BitBooster 12 V DC, 2 x 200 mA, short-circuit-proofPower supply 100 – 240 V AC, 50/60 HzPower consumption max. 50VA, 20 W (AC)Operating temperature –10 °C … +55 °CStorage temperature -25 °C … +70 °CDimensions 436 x 44 x 250 mmWeight ca. 4080 g
