| Open-space range | Up to 800 m line of sight under suitable conditions |
| Wall penetration reference | 1 wall: up to 100 m; 2 walls: up to 80 m; 3 walls: up to 60 m; 4 walls: up to 40 m |
| Receiver expansion | Up to 200 compatible receivers per transmitter |

| Audio latency | <0.5 ms |
| Frequency response | 20 Hz–20 kHz |
The manufacturer-rated maximum range is up to 800 m in an open, unobstructed line-of-sight environment. Reference wall-penetration distances are up to 100 m through one wall, 80 m through two walls, 60 m through three walls and 40 m through four walls. One-to-one and one-to-many configurations use the same transmission-distance rating. Actual performance depends on wall thickness and materials, antenna placement, local RF interference and installation conditions; reinforced concrete and brick can reduce the range further. Additional receivers are required for multi-receiver setups.
Frequently asked questions
Can other UHF frequency bands be supplied?
Measy states that custom UHF frequency bands can be provided for project requirements.
Why is the transmission range listed as both 100 m and 800 m?
The AU680A can reach up to 800 m in an open area with a clear line of sight. Indoors, walls and building materials reduce the effective range. The reference distance is up to 100 m through one wall, 80 m through two walls, 60 m through three walls and 40 m through four walls.
Can several systems operate in the same area?
Yes. Up to 10 complete transmitter-receiver systems can operate in the same area by default when their channels are configured appropriately. Custom channel planning may support additional systems for project requirements.
Can one transmitter work with multiple receivers?
Yes. One AU680A transmitter supports up to 200 compatible receivers. The transmission-distance rating is the same for one-to-one and one-to-many configurations. Choose the receiver quantity that matches your installation.
Can it be used with instruments such as electric guitars or keyboards?
Yes. The 6.35 mm interface supports compatible instrument-level connections such as electric guitars and keyboards.
How can ground-loop hum be reduced?
The receiver includes a Lift/Earth ground switch, and the transmitter supports balanced XLR operation. These controls can help reduce ground-loop noise in compatible setups.
Is the latency suitable for live audio?
Measy specifies audio latency below 0.5 ms for the AU680A, making it suitable for low-latency live audio applications.
Choose the right wireless audio system
Choose AU680A when you need XLR, RCA, 6.35 mm and 3.5 mm connections, ultra-low latency and long-range one-to-many audio distribution. For detachable BNC antennas and a longer outdoor line-of-sight rating, compare the AU680B BNC/XLR 1000 m system. For a simpler RCA/AUX installation with a 100 m rated range, see the AU680 wireless audio extender.
