6. Professional XLR Signal Management
The AU680(BNC) transmitter provides a Balanced / Unbalanced XLR switch, allowing the system to adapt to different audio signal configurations.
Balanced Mode
Recommended for:
- Professional mixers
- Professional audio processors
- PA systems
- Stage equipment
- Long cable runs before wireless transmission
Balanced transmission provides improved resistance to external electromagnetic interference.
Unbalanced Mode
Suitable for:
- Consumer audio devices
- Certain media players
- Some musical instruments
- Consumer-level audio sources
This flexibility allows AU680(BNC) to integrate into both professional and consumer audio environments.
7. Ground Loop Noise Elimination
The AU680(BNC) receiver provides a Lift / Earth ground switch.
This feature is particularly useful when the transmitter and receiver are connected to different pieces of powered audio equipment.
If unwanted hum or buzzing is caused by a ground loop, the receiver's ground configuration can be adjusted to help eliminate the interference.
Typical application
Mixer → AU680(BNC) TX → Wireless UHF → AU680(BNC) RX → Active Speaker
The Ground Lift function can help reduce unwanted 50/60 Hz ground-loop hum in suitable installations.

| Through 1 wall | ≤100 m |
| Through 2 walls | ≤80 m |
| Through 3 walls | ≤60 m |
| Through 4 walls | ≤40 m |
Wall penetration results are for reference only. Reinforced concrete, brick walls, metal structures, RF interference and other obstacles can significantly reduce the effective transmission distance.

Important
AU680(BNC) is a wireless audio signal transmission device, not a power amplifier.
It transmits audio line-level signals wirelessly.
Therefore:
AU680(BNC) RX → Active Speaker
is a direct application.
For a passive speaker system:
AU680(BNC) RX → Power Amplifier → Passive Speakeris required.
14. Competitive TechnicalAdvantages
UHF Instead of Bluetooth
AU680(BNC) is designed for professional wireless audio signal transmission rather than ordinary consumer Bluetooth audio applications.
Key advantages include:
- Longer transmission distance
- Very low latency
- Multi-receiver capability
