Description

The ATEN AP412 is a professional 4-channel Class-D power amplifier delivering 120W per channel, purpose-built for commercial public address systems, installed AV, and enterprise audio deployments. Its built-in Sigma DSP — configurable via WebGUI or ATEN Audio Wizard — provides a full processing suite including 5-band EQ, speaker EQ, compressor, delay, and limiter with up to 20 storable presets. Flexible output modes support 4/8-ohm low-impedance or 70/100V line speaker systems, while balanced and unbalanced mic/line inputs ensure compatibility with a wide range of signal sources.

The AP412 features an expansion slot accepting the AP901 2-channel Dante card for Audio-over-IP integration or the AP902 Mic/Line Preamp card for additional inputs, making it a scalable foundation for growing installations. RS-232 and Ethernet control integrate natively with the ATEN VK Control System, and a fanless, PFC-equipped design ensures silent, energy-efficient operation in rack environments. Comprehensive protection circuitry guards against short circuits, over/under-voltage, overtemperature, and high-frequency overload.

FAQs

Q: What speaker systems is the ATEN AP412 compatible with?
A: The AP412 supports both low-impedance (4/8-ohm) and high-impedance (70V/100V line) speaker systems, making it suitable for everything from small meeting rooms to large-scale distributed PA installations across corridors, warehouses, and multi-zone commercial spaces.

Q: How is the DSP on the AP412 configured?
A: The built-in Sigma DSP is fully configurable via the ATEN WebGUI (browser-based, no software install required) or the ATEN Audio Wizard application. You can program 5-band EQ, speaker EQ, compressor, delay, and limiter settings, and save up to 20 presets for quick scene recall.

Q: Can the AP412 be integrated into a Dante Audio-over-IP network?
A: Yes. The AP412 includes an expansion slot that accepts the optional AP901 2-Channel Dante Expansion Card, enabling direct integration into Dante AoIP networks for networked audio distribution without additional hardware converters.

Q: Is the AP412 compatible with the ATEN VK Control System?
A: Yes. The AP412 supports RS-232 and Ethernet control interfaces and integrates natively with the ATEN VK Series Control System, allowing it to be managed as part of a larger room automation or AV control solution.

Q: Is the AP412 suitable for permanent rack installation in noise-sensitive environments?
A: Absolutely. The AP412 uses a completely fanless design with a PFC power supply, eliminating fan noise and reducing dust ingress — ideal for permanent installation in boardrooms, broadcast facilities, houses of worship, and any environment where background noise is a concern.

Q: Can I purchase the ATEN AP412 in Australia from IP Trading?
A: Yes. The ATEN AP412 is available in stock at iptrading.com.au and ready for fast dispatch Australia-wide. IP Trading is a specialist B2B IT and AV hardware reseller supplying businesses, integrators, and government organisations across Australia.
