What is Sound Devices Spectraband Technology?

SpectraBand Technology: Revolutionizing Wireless Audio Transmission for Sound Professionals

The Power of SpectraBand Technology

SpectraBand is a groundbreaking technology that provides the Sound Devices Astral Lineup with an unparalleled tuning range of 470 MHz – 1525 MHz. This innovative solution offers sound professionals a multitude of benefits, thus including: increased operating frequencies, cost savings, worldwide compatibility, and exceptional filtering capabilities.

A World of Operating Frequencies at Your Fingertips

SpectraBand technology expands wireless microphone frequencies, while overcoming limited spectrum for sound professionals in any location. In the USA, this translates to approximately 285 MHz of available spectrum. In the UK, it offers access to around 383 MHz of available spectrum. This expanded range enables seamless global travel, all while being equipped devices use legal frequency bands worldwide in any country.

One Device, Unlimited Possibilities

SpectraBand-equipped devices eliminate the need for purchasing multiple pieces of specialized equipment for different locations. Furthermore, they provide a cost-effective solution for sound professionals. It can be used anywhere, and also offers unparalleled convenience and adaptability.

Unmatched Filtering for Optimal Performance

SpectraBand technology incorporates strong filtering, enhancing immunity to nearby strong signals (e.g., DTV transmitters), improving reception quality. This is achieved through the use of brick-wall, SAW-based front-end filters. These components play an essential role in maintaining top-quality performance in any RF system.

Key Technologies Behind SpectraBand

SpectraBand’s incredible range is facilitated by cutting-edge technologies, such as wide-range local oscillators (LO), wide-range modulators/demodulators, and high dynamic-range low-noise amplifiers (LNA).

  • Filtering: Proper filtering is crucial for optimal RF system performance. SpectraBand will utilize brick-wall SAW filters to achieve unparalleled immunity to out-of-band interference. This allows Spectraband to pass competitors in both selectivity and signal attenuation.
  • Local Oscillator (LO) and modulator/demodulator: Both the modulator and LO in a wireless mic transmitter must be carefully designed to operate reliably across the entire 470 MHz – 1525 MHz range. SpectraBand employs the latest in low-current, low phase-noise LO and FPGA design, furthermore helping it meet these requirements.
  • Low Noise and High IP3 LNA: The LNA is a critical component in the RF signal path, and its quality directly affects system performance. SpectraBand’s LNA boasts a noise figure (NF) of just 0.3 dB and an output IP3 of +39 dBm, ensuring quiet operation with ample headroom.
