Delivers 120W per channel and receives balanced/unbalanced mic/line-level signals to drive 4/8-ohm low impedance or 70/100V line loudspeaker systems

AP412 is a 4-channel DSP-equipped amplifier that delivers 120W per channel and receives balanced / unbalanced mic / line-level signals to drive 4 / 8-ohm low impedance or 70 / 100V line loudspeaker systems. It also supports Lo-Z / Hi-Z in Bridge mode to deliver higher power.

Configurable via intuitive WebGUI / ATEN Audio Wizard, the built-in DSP allows Speaker EQ, 5-band EQ, compressor, delay, limiter, and up to 20 presets for precise tuning and extensive audio system protection. The ground-lift switch helps eliminate unwanted hum noises from power circuit. Immersive sound experience is delivered without compromise on power efficiency with the Class D design. Customizable Auto Standby mode enables AP412 to automatically switch to “sleep” when the signal level falls lower than -40 / -50 dBu for 10 / 15 / 25 minutes.

With the system protection circuit, the amplifier is prevented from damages led by shorted outputs, over / under-voltage, high-frequency overload, and overtemperature. Plus, AP412 will be muted when the heat sink temperature exceeds the limit. The fanless design avoids fan noise and prevents dust from building up inside the chassis.

AP412 becomes compatible with Dante audio when working with AP901 expansion card or receives two more channels of mic / line signals with AP902 expansion card. It can be integrated with ATEN VK Control System via RS-232 / Ethernet for comprehensive control from a distance. The 1U casing is available for rack mounting. AP412 assures reliable amplification with professional audio quality and higher power delivery for larger commercial spaces.
