ATEN AP212 is a dual-channel DSP-equipped amplifier that delivers 120 W per channel in a compact enclosure. The support for balanced / unbalanced line level inputs and the capability of driving 4 ohm low impedance or 70/100V line (in Bridge mode) loudspeaker systems have made AP212 suit a wide range of public address applications. Configurable through an intuitive WebGUI, the built-in DSP allows Speaker EQ, 5-band EQ, delay, limiter, and up to 20 presets for precise tuning and extensive audio system protection purposes. Ground lift is deployed to eliminate unwanted hum noises from power circuit. Immersive sound experience is delivered with no compromise on power efficiency thanks to the amplifier’s Class-D design and ENERGY STAR qualification, conserving energy while lowering operational costs. Customizable Auto Standby mode enables the AP212 to automatically switch to “sleep” when the signal level comes lower than -40 / -50 dBu for 10 / 15 / 25 minutes.
