SIRUS Quad C 823 MKII UHF Conference Table Microphone Unit
Product Information
- The Quad C 823 MKII and Quad C 470 are wireless audio transmission devices designed for transmitting audio signals from microphones or instruments to amplifiers or active speakers. These devices operate on specific frequency bands and have a maximum transmission power of 30 mW. The Quad C 823 MKII operates in the frequency range of 823 MHz to 832 MHz and 863 MHz to 865 MHz, while the Quad C 470 operates in the frequency range of 470 MHz to 526 MHz.
- The devices utilize frequency modulation (FM) for transmission and have a total harmonic distortion (THD) of less than 0.5%. They provide a signal-to-noise ratio of over 102 dB (A). The power is supplied by two round cell batteries (AA, LR6, 1.5 V) or corresponding rechargeable batteries.
Product Usage Instructions
- Ensure proper disposal of plastic bags, packaging, etc. to prevent choking hazards for babies and young children.
- Do not allow children to detach small parts from the product as they may swallow them and choke.
