PRODUCT SPECIFICATION (V1.5) SPECTERA SEK (UHF) | SEK (1G4) ARCHITECT‘S SPECIFICATION Sennheiser Spectera/ System description / Intro text Digital bidirectional (uplink/ downlink) multicarrier/ TDMA/ TDD wireless system for simultaneous transmission of up to 32 audio input and output channels. The system shall use digital broadband transmission technology for this purpose. It shall be based on wireless multichannel audio systems technology (WMAS) and its combination of modulation and multi- plexing methods. Data and audio transmission, as well as remote control and monitoring data, shall be carried out via a single RF carrier, avoiding the 2.4 ISM band. The system shall operate in the TV UHF band or the 1.4/1.5 GHz band. It shall operate with an RF channel bandwidth of 6 or 8 MHz and shall pair up to 128 mobile devices per RF channel. It shall provide a switching bandwidth of 194 MHz (UHF) or 128 MHz (1.4 GHz), which shall be identical for all RF compo- nents in the system; the base station shall be frequency-independent and both frequency bands shall be operated simul- taneously by a single base station. The system shall consist of the following components: Base Station in 19" /1U format (shall allow up to two independent wideband RF carriers in UHF or 1G4 band). The base station shall process only digital audio signals without any analog components (compander, RF emphasis, etc.).

• Bodypacks f or simultaneous use as both in-ear monitoring receiver and transmitter for microphone/line audio signals.
• Digital bidirectional ant enna with integrated RF components (up to four pieces shall be used simultaneously).
• Proprietar y desktop application for comprehensive system management.
• Handheld microphone (in de velopment). The system can be operated with only one antenna. Up to four antennas can be connected to a single base station and operated in multi-zone mode with improved antenna coverage and optimized signal-to-noise ratio. The connection bet- ween the base station and antennas shall be a digital 1 Gb/s connection via a CAT5e (or higher) cable with a maximum length of 100 m. For all system components, data and audio shall be transmitted via a single RF carrier. The system shall support up to 128 audio channels per RF channel, with each channel individually configurable (audio codec, latency, operating range). The audio frequency response of the system shall be 20 Hz to 20,000 Hz, the system latency shall be min. 0.7 ms for stereo audio links/ 1 ms for mono audio links. The system shall offer 11 audio link/transmission modes, including a mode for linear PCM format. Each channel can be operated in a different mode; Modes can be changed at any time and without rebooting. The internal audio processing shall be done in 32-bit float format. 100 – 240 V power supply units, Dante and optional MADI connectors shall be redundant; a total of up to four antennas can be operated simultaneously. The system shall have AES 256 end-to-end encryption. The system shall be remotely controlled and monitored via Windows, macOS native software and a WebUI. The system shall comply with all relevant international standards and regulations for wireless audio transmission. It shall be certified for use in a wide variety of regions (including the EU, USA and Canada).

PRODUCT SPECIFICATION (V1.5) SPECTERA SEK (UHF) | SEK (1G4) Digital bidirectional bodypack (Sennheiser Spectera SEK UHF) Digital bidirectional bodypack transceiver for wireless transmission of digital audio and control data. The transceiver shall simultaneously transmit both stereo/mono IEM/IFB and mono mic/line signals via a single antenna via a 6 or 8 MHz RF channel to match the wireless system described in the system description. The bodypack shall provide continuous interference measurement for the RF channel without interrupting the audio signals. Interference or deterioration in connection quality shall be indicated via the proprietary software or WebUI. In addition, permanent full remote control and monitoring of IEM volume and balance, audio level, audio settings, battery status, and RF channel quality parameters shall be provided via the software. The transceiver shall have a display that shows information even when the batteries are removed. In addition, the tran- sceiver shall offer a power saving mode that activates automatically when it is out of range of its coupled transceiver antenna for a certain period of time. The antenna of the bodypack shall be replaceable, the battery shall be charged in a separate 19" charging station or via the charging contacts on the SEK in a charging cradle. The AD/DA converters of all connected bodypacks shall be clocked by a mutual word clock signal. The synchronized word clock for all audio signals shall also allow for immersive on-air 3D audio recording and playback. The headphone volume shall be adjusted in 0.5 dB steps.
