NEXT Audiocom AD500

Experience ultimate flexibility in multi-zone installations with the AD500 – a compact half-rack 1U 4-channel Class D amplifier delivering total 500W with intelligent power sharing up to 250W per channel. Drive mixed low-Z (4–16Ω) and high-Z (70V/100V) loudspeaker systems simultaneously thanks to per-channel software-selectable modes and dynamic power allocation between channel pairs. The state-of-the-art full-matrix DSP engine, tightly integrated with the amplifier section, provides far more accurate dynamics processing than separate components while eliminating the need for external processors.

Control everything remotely via the built-in web interface – connect directly through integrated Wi-Fi access point or Ethernet from any PC, tablet or smartphone without installing software. Fine-tune input routing, 4-zone management, room correction, parametric EQ, crossovers, limiters, delays and more, plus monitor all vital amplifier parameters in real time. Additional SPDIF digital I/O and five programmable GPIO ports (for remote volume pots, standby/mute control) make system expansion and integration effortless. Universal PFC power supply ensures stable worldwide operation.
