Two-channel Class D amplifier delivering 60 W per channel into 4-ohm speakers, or 70 / 100 V lines in bridge mode, with WebGUI-configurable DSP: 5-band EQ, delay, limiter and 20 presets.

Features

  • A dual-channel DSP-equipped amplifier that delivers 60 W per channel in a compact enclosure
  • Supports balanced / unbalanced line level inputs and drives 4 ohm low impedance or 70/100V line (in Bridge mode) loudspeaker systems
  • Built-in WebGUI-configurable DSP allows speaker EQ, 5-band EQ, delay, limiter, and up to 20 presets for precise tuning and system protection
  • Ground lift deployed to eliminate unwanted noises from power circuit.
  • Class-D design with ENERGY STAR qualification for high power efficiency
  • Customizable Auto Standby mode – Amplifier automatically switches to “sleep” when the signal level comes lower than -40 / -50 dBu for 10 / 15 / 25 minutes
  • Integrated protection circuit – Protects the system from damages caused by Amp shortcut, Amp output over/under voltage, high frequency overload, and overtemperature
  • Amplifier will be muted when the heat sink temperature exceeds the limit
  • Fanless design – Avoids fan noise and prevents dust from building up
  • Expansion slot for add-on expansion card – Install AP901 2-CH Dante Expansion Card to make the sound system compatible with Dante network or AP902 2-CH Mic/Line Pre-AMP Expansion Card to receive two channels of mic / line input signals
  • Supports VK Control System via RS-232 and Ethernet connection
  • Supports rack or surface-mounting
  • Firmware upgradable
