Description
The Aten AP412 is a 4-channel Class D power amplifier with integrated DSP, designed for commercial and professional audio systems that need reliable power, flexible loudspeaker support, and detailed signal control in a compact 1U format. It delivers 120W per channel at 4Ω or 8Ω, and supports higher-power bridge operation for 8Ω or 70V/100V high-impedance speaker lines.
Built to accept balanced or unbalanced mic and line-level sources, the AP412 provides +48V phantom power for microphone integration and combines amplification with onboard processing through a WebGUI or ATEN Audio Wizard. Speaker EQ, 5-band EQ, compressor, delay, limiter, priority control, solo monitoring, and up to 20 presets help tailor system performance for speech and music while protecting connected loudspeakers.
For installations where uptime, low maintenance, and remote management matter, the Aten AP412 adds a fanless chassis, ground-lift switch, integrated protection circuitry, Auto Standby operation, firmware upgrades, and RS-232/Ethernet control compatibility. Expansion support for Dante or additional mic/line inputs makes it well suited to larger rooms and distributed audio environments.
Key Features:- 4-Channel 120W Class D Amplification: Delivers 120W per channel at 4Ω or 8Ω, with 240W per channel in bridge mode at 8Ω or 70V/100V, giving installers the flexibility to drive both low-impedance and constant-voltage loudspeaker systems.
- Integrated Sigma DSP: Provides speaker EQ, 5-band EQ, compressor, delay, limiter, priority, and up to 20 presets, allowing accurate system tuning, clearer speech reproduction, and stronger loudspeaker protection.
- Mic/Line Input Support with Phantom Power: Accepts balanced and unbalanced mic/line sources and supplies +48V phantom power, simplifying connection of paging microphones, media sources, and installed audio front ends.
- Fanless 1U Design: Eliminates fan noise and reduces dust intake inside the chassis, helping maintain quiet operation and lower maintenance demands in meeting spaces, hospitality venues, and education environments.
- Protection and Power Management: Includes safeguards for output short circuit, amp output over/under voltage, high-frequency overload, and overtemperature, while customizable Auto Standby reduces energy use when signal levels fall below -40 or -50 dBu for 10, 15, or 25 minutes.
- Expansion Card Slot: Supports the AP901 2-channel Dante expansion card for networked audio integration or the AP902 2-channel mic/line preamp card for added input capacity, making the amplifier easier to adapt to changing system requirements.
- Remote Control Connectivity: Works with ATEN VK Control System over RS-232 or Ethernet for centralized operation, monitoring, and integration into managed AV control systems.
- Corporate Meeting Rooms: Powers foreground audio, speech reinforcement, and presentation sound with DSP tuning and remote control support for managed conferencing environments.
- Hospitality and Retail Audio: Drives 4/8-ohm or 70V/100V loudspeaker layouts for background music and paging across larger commercial spaces using efficient Class D amplification.
- Education and Training Facilities: Supports microphones with +48V phantom power and offers preset-based tuning for lecture rooms, multipurpose classrooms, and instructional spaces.
- Installed Networked Audio Systems: Expands with Dante connectivity or additional mic/line channels to fit distributed audio systems requiring scalable input and control options.
