As part of the Spectera wideband ecosystem, this bodypack manages an IEM\/IFB stream and a mic\/line stream simultaneously, making it well suited for broadcast, theater, and large-scale live production. It covers the 470-608 MHz and 630-698 MHz UHF ranges and integrates directly with the Spectera Base Station for centralized control. This unit is the SEK (UHF) variant, manufacturer part number 509164.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe SPECTERA SEK consolidates monitoring and microphone transmission into one bodypack, reducing the number of devices a performer or talent must carry on a single bidirectional RF link. \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/Zz04YWNkOTEzMGU3Y2YxMWYwYjk1OWNlM2Q3NWM0MGYwNw.png?v=1780789063\" alt=\"Sennheiser SPECTERA SEK bidirectional UHF bodypack front view\"\u003e Audio engineers can remotely control and monitor IEM volume, audio level, RF health, and battery status through the Spectera WebUI and SoundBase software, all over the same RF connection used for audio. A persistent E-Ink display keeps the assigned name and key information visible even when the battery is removed, which simplifies inventory and channel management in a busy rack room or backstage area. The bodypack uses AES 256 encryption on the RF link between the Base Station and the SEK, protecting confidential content in broadcast and corporate deployments. It accepts a wide range of Sennheiser lavalier and headset microphones via a 3-pin locking connector and drives in-ear monitors through a 3.5 mm connector. A rugged metal housing protects the electronics in demanding touring and broadcast environments. The unit is powered by the rechargeable lithium-ion BA 70 battery, which is sold separately, and delivers up to 7 hours of operating time depending on the selected audio link mode. An LED meter and status LED provide at-a-glance feedback during a performance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBidirectional RF Link\u003c\/strong\u003e — Manages an IEM\/IFB stream and a mic\/line stream simultaneously over a single encrypted RF connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUHF Frequency Coverage\u003c\/strong\u003e — Operates across the 470-608 MHz and 630-698 MHz UHF ranges for flexible spectrum coordination.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAES 256 Encryption\u003c\/strong\u003e — Secures the RF connection between the Spectera Base Station and the bodypack for confidential audio transmission.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePersistent E-Ink Display\u003c\/strong\u003e — Keeps the assigned name and status visible on screen even when the battery is removed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemote Control and Monitoring\u003c\/strong\u003e — Allows engineers to adjust IEM volume and monitor RF health and battery status through the Spectera WebUI and SoundBase software.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBroad Microphone Compatibility\u003c\/strong\u003e — Connects to Sennheiser lavalier and headset microphones with a 3-pin locking connector and in-ear monitors with a 3.5 mm connector.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRugged Metal Housing\u003c\/strong\u003e — Protects internal electronics in demanding touring, theater, and broadcast deployments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRechargeable Operation\u003c\/strong\u003e — Runs up to 7 hours on the rechargeable lithium-ion BA 70 battery depending on the selected audio link mode.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTypical Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBroadcast studio\u003c\/li\u003e\n\u003cli\u003eAuditorium\u003c\/li\u003e\n\u003cli\u003eHouse of worship\u003c\/li\u003e\n\u003cli\u003eAll-hands room\u003c\/li\u003e\n\u003cli\u003eCommercial meeting space\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer Part Number (SKU)\u003c\/td\u003e\n\u003ctd\u003e509164\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eWireless Microphone Systems (Bidirectional Bodypack)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency Range\u003c\/td\u003e\n\u003ctd\u003eUHF 470-608 MHz and 630-698 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRF Encryption\u003c\/td\u003e\n\u003ctd\u003eAES 256\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio Streams\u003c\/td\u003e\n\u003ctd\u003eSimultaneous IEM\/IFB and mic\/line\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMicrophone Connector\u003c\/td\u003e\n\u003ctd\u003e3-pin locking connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIEM Connector\u003c\/td\u003e\n\u003ctd\u003e3.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay\u003c\/td\u003e\n\u003ctd\u003ePersistent E-Ink display, LED meter, status LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery\u003c\/td\u003e\n\u003ctd\u003eRechargeable lithium-ion BA 70 (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Time\u003c\/td\u003e\n\u003ctd\u003eUp to 7 hours depending on audio link mode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing\u003c\/td\u003e\n\u003ctd\u003eRugged metal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003ch3\u003eWhat microphones are compatible with the SPECTERA SEK?\u003c\/h3\u003e\u003cp\u003eThe bodypack accepts a wide range of Sennheiser lavalier and headset microphones that use the 3-pin locking connector, giving integrators flexibility when matching capsules to talent.\u003c\/p\u003e\u003ch3\u003eDoes the SEK require a separate battery?\u003c\/h3\u003e\u003cp\u003eYes.
