SIRUS Quad C 823 MKII UHF Conference Table Microphone Unit User Guide

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

1. Ensure proper disposal of plastic bags, packaging, etc. to prevent choking hazards for babies and young children.
2. Do not allow children to detach small parts from the product as they may swallow them and choke.
3. Never let children play unattended with electrical devices.
4. When inserting batteries, ensure the proper polarity is observed to avoid damaging the device or batteries.
5. If the device is not going to be used for a longer period, remove the batteries to prevent possible damage from leaking batteries.
6. Before using the device, check the regulations regarding the frequencies used for audio signal transmission in your country and register the operation if required.
7. Avoid using liquid cleaners such as benzene, thinners, or flammable cleaning agents to clean the device.
