Answer:
The AU-50XT includes a built-in 100V line transformer with selectable rear rotary switch taps for 50W (200Ω), 40W (250Ω), 20W (500Ω), 10W (1kΩ), and 5W (2kΩ). It achieves an IP66 ingress rating under EN 60529 when horn-mounted.
Designed for distributed 100V constant-voltage public address networks, the Ahuja AU-50XT incorporates a multi-tap line matching transformer. Users can adjust impedance and power draw via an integrated rotary switch located at the rear of the unit:
- 50W Tap: 200 Ω impedance
- 40W Tap: 250 Ω impedance
- 20W Tap: 500 Ω impedance
- 10W Tap: 1,000 Ω (1 kΩ) impedance
- 5W Tap: 2,000 Ω (2 kΩ) impedance
For outdoor deployment, the unit features a rugged die-cast aluminium acoustic head and provides an IP66 ingress protection level against dust and water jets in accordance with EN 60529 when paired with a compatible reflex horn.
