Includes EW-D EM rackmount receiver (R4-9) and SKM-S handheld transmitter, equipped with MMD 835 dynamic cardioid capsule, ideal for vocals and live presentations. The system supports 2,240 selectable frequencies over a 56 MHz bandwidth, allowing up to 90 simultaneous channels without interference due to the 600 kHz equidistant tuning grid<\/p>\n<p>Audio quality is guaranteed by 24-bit depth, a dynamic range of 134 dB and ultra-low latency of 1.9 ms, ensuring faithful sound reproductions, even in the case of high SPL performances. The system uses UHF transmission with automatic diversity switching, optimizing reception between two removable BNC antennas and reducing drop-outs.<\/p>\n<p>Setup is simplified via the Smart Assist app (iOS and Android), which uses Bluetooth BLE connection (up to about 120 feet\/36 m) to automatically synchronize transmitter and receiver, scan frequencies, and monitor battery status.<\/p>\n<p>The battery life of the Sennheiser EW-D 835-S (R4-9) is up to 8 hours with AA batteries and can go up to 12 hours using the BA 70 rechargeable battery pack (not included). The receiver features balanced XLR and unbalanced 1\/4 jack audio outputs, backlit OLED screen for RF\/AF, intuitive menu and complete rack kit included.<\/p>\n<p>Constructed with half-rack metal chassis (212 \u00d7 44 \u00d7 189 mm, weight about 1 kg), the system operates reliably between -10 \u00b0C and +55 \u00b0C and up to 95 percent humidity without condensation. Ultimately, the Sennheiser EW-D 835-S (R4-9) is the perfect choice for professionals who need high-quality wireless audio streaming, fast smart setup, wide RF scalability and full European regulatory compatibility.<\/p>\n<\/div>\n<table class=\"table-product-2-colonne-genrale\">\n<tbody>\n<tr>\n<td class=\"table-colonna-2a-product\">Weight<\/td>\n<td class=\"table-colonna-2b-product\">0.30 kg (including MMD 835 module)<\/td>\n<\/tr>\n<tr>\n<td class=\"table-colonna-2a-product\">Dimensions (receiver)<\/td>\n<td class=\"table-colonna-2b-product\">21.2\u202f\u00d7\u202f4.4\u202f\u00d7\u202f18.9\u202fcm<\/td>\n<\/tr>\n<tr>\n<td class=\"table-colonna-2a-product\">RF sensitivity \/ microphone<\/td>\n<td class=\"table-colonna-2b-product\">2.1\u202fmV\/Pa<\/td>\n<\/tr>\n<tr>\n<td class=\"table-colonna-2a-product\">Audio output (receiver)<\/td>\n<td class=\"table-colonna-2b-product\">+18 dBu max (balanced XLR output)<br \/>\n+12 dBu max (1\/4\u2033 unbalanced output)<\/td>\n<\/tr>\n<tr>\n<td class=\"table-colonna-2a-product\">Frequency band<\/td>\n<td class=\"table-colonna-2b-product\">Up to 56 MHz bandwidth<br \/>\nRanges vary depending on the region variant (e.g., 470.2\u2013526 MHz, 520\u2013576 MHz, &#8230; up to 1799.8 MHz)<\/td>\n<\/tr>\n<tr>\n<td class=\"table-colonna-2a-product\">What&#8217;s in the box<\/td>\n<td class=\"table-colonna-2b-product\">1 x EW\u2011D EM rack receiver<br \/>\n1 x EW\u2011D SKM\u2011S handheld transmitter<br \/>\n1 x MMD 835 microphone module<br \/>\n1 x MZQ 1 microphone clip<br \/>\n2 x Rod antennas<br \/>\n1 x Power supply with international adapters<br \/>\n1 x Rack mounting kit<br \/>\n4 x Rubber feet<br \/>\n1 x Quick Start Guide<br \/>\n1 x Safety Guide<br \/>\n1 x Manufacturer&#8217;s declaration sheet<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Sennheiser EW-D 835-S (R4-9) digital wireless system: 552-607 MHz band, 24 bits, 134 dB dynamic range, 1.9 ms latency, MMD 835 cardioid capsule, Smart Assist App, up to 12 h battery life, rack kit included.<\/p>\n","protected":false},"featured_media":490849,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"product_group":[48226],"promo_group":[],"etheme_brands":[{"term_id":45108,"name":"Sennheiser","slug":"sennheiser-en","term_group":0,"term_taxonomy_id":45108,"taxonomy":"brand","description":"<div class=\"container-tassonomia-brand\">\r\n\r\n<div class=\"column-tassonomia-brand-1\"><img class=\"photo-logo-tassonomia-brand\" src=\"https:\/\/martcom.eu\/assets\/media\/logos\/sennheiser-brand-1.png\" \/><\/div>\r\n\r\n<div class=\"column-tassonomia-brand-2\">\r\n<h1 class=\"titolo-tassonomia-brand\">Sennheiser Headphones, Microphones and Wireless Systems<\/h1>\r\n<div class=\"description-tassonomia-brand\">Sennheiser blends German engineering with innovative spirit.
