ATEN AP212 Dual 120W Class D Power Amplifier with DSP
Overview
The ATEN AP212 is a dual-channel 120W Class D power amplifier with built-in DSP, designed for commercial AV installations — boardrooms, lobbies, warehouses, and public address systems where managed audio distribution and remote RS-232 control are required. Class D topology keeps heat output low enough for rack-dense deployments, and the AP212's 100–240V universal input with power factor correction means it runs on the same UPS-backed circuits as your network gear without special provisioning. The built-in DSP eliminates the need for a separate signal processor in straightforward installations, reducing rack space and cabling complexity.
Compatibility
The AP212 supports both Lo-Z speaker loads (4Ω) and Hi-Z distributed speaker systems — 70V lines at 20Ω and 100V lines at 40Ω — making it compatible with standard commercial ceiling speaker runs up to 100V. The 600Ω balanced line output allows direct connection to mixers, DSP matrices, or zone controllers that accept professional line-level signals. RS-232 control (3.5mm 3-pin terminal block, 19200 baud, 8N1) integrates with control systems that send serial command strings — confirm your controller supports 19200 baud 8N1 before wiring. Management is handled via ATEN Audio Wizard software, available for Windows 7/10 and macOS (v1.2.113), which enables DSP parameter configuration and firmware updates (current firmware v1.1.104).
Installation Notes
Input power is 100–240V~, 50/60Hz, rated at 4A with active PFC — size your circuit accordingly; actual consumption is 41.9W at 110V and 39.6W at 220V (note: these figures reflect 1/8 maximum power output per ATEN's test methodology, not full-load draw). Thermal protection, output short-circuit protection, over/under voltage protection, and high-frequency overload protection are all built in, reducing the risk of damage from miswired speaker runs. Storage temperature is rated to -20–60°C; confirm the install environment stays within that range for equipment stored before commissioning. FCC, CE, and UKCA certifications cover US, EU, and UK deployments without additional compliance work.
