Next Audio AD500 4-Channel Amplifier With DSP [100V|8Ω]

Description

The AD500 is a 4 x 125 W Class D multi-purpose installation amplifier in 1RU half rack unit with flexible power distribution among its four output channels power sharing up to 250W per channel driving both conventional low impedance (4Ω to 16Ω) loudspeakers and high impedance (70V/100V) transformer coupled loudspeakers or any mix of the two. The on board, state-of-the-art, full matrix, DSP engine can be configured to suit a wide range of tasks, without the need for additional equipment, to drive a wide range of loudspeaker systems. Everything you need is right there. The close integration of processing and amplification allows the DSP to monitor and better adapt to amplifier behavior, making dynamics processing far more accurate and effective than that typically achieved with separate components. The active PFC (Power Factor Correction) power supply technology enables universal AC mains operation and delivers consistent, regulated power worldwide.

Features

Integrated Web Interface

The AD500 can be accessed anytime, anywhere through Wi-Fi via a built-in Wireless-Access-Point (WAP) or through ethernet for simple connection easy configuration, controlling and powering any speaker system, creating the most impressive multi-zone sound system in minutes. An easy-to-use web-based interface allows remote control of all DSP functions as well as monitoring of all amplifier vital functions from any PC, tablet, or smartphone, regardless of operating system. No software to install (it’s built into the AD500). Simply connect via the Ethernet port or the built-in Wi-Fi, and you’re ready to go.

• Outputs
  Software-selectable multi-mode operation with switchable Normal Low Z (4Ω to16Ω) or Bridge Hi Z (70V/100V) allows you to mix and match speaker types as needed.
• Digital
  The SPDIF Digital I/O can connect to other compatible equipment or bridge two AD500 amplifiers to digitally expand the system.
• GPIO
  Five programmable GPIO pins are provided as additional control lines. These pins can be programmed to remotely control the volume levels for each Zone by means of external remote potentiometers. Power On/Off, Standby and Mute are also remotely controllable via GPIO.

Power Sharing technology distributes dynamically the available power between each channel pair, so that it can be used where it is needed the most, maximizing the efficiency of the system. This technology allows a single channel to run at double-power, 250W (B), or balance power asymmetrically between channels, for example 200W+50W (C), to meet different load requirements. Other combinations are possible (A, B) offering maximum flexibility for the installer.

The integrated web interface controls a powerful signal processing engine extending the level of functionality. The state-of-the-art full matrix Digital Signal Processing (DSP) can be configured to suit a wide range of tasks, without the need for additional equipment. From processing input sources, managing up to 4 zones, correcting up to 4 independent rooms, to fine-tuning 4 speaker outputs, all the powerful processing tools you need are here.
