Frequently asked questions
Which AU680B version is sold on this page?
This listing is for the professional BNC-antenna, XLR-equipped AU680B version with a manufacturer-rated outdoor line-of-sight range of up to 1000 m. It is not the separate 100 m RCA/AUX product that may also appear under the AU680B model name.
How many receivers can one transmitter support?
One transmitter supports up to 200 compatible receivers. Additional receivers are required for one-to-many installations.
Is the 1000 m range guaranteed in every venue?
No. The 1000 m rating applies to outdoor, unobstructed line-of-sight conditions with minimal interference. Indoors, the reference range is up to 200 m under suitable conditions, and walls or local RF interference can reduce it further.
What equipment can connect to AU680B?
AU680B supports professional and consumer analog audio equipment through XLR, 1/4-inch TRS, RCA left/right and 3.5 mm connections.
How does it compare with AU680A?
AU680B is the longer-range BNC-antenna option. The AU680A offers a manufacturer-rated range of up to 800 m line of sight, 20 wireless channels and the same broad mix of professional and consumer analog interfaces.
