dBTechnologies IA3204D 800W 4-Channel at 4-Ohm 70V/100V Power Amplifier

Overview

The DB Technologies IA3204D is a high-performance 4-channel Class-D amplifier designed to provide exceptional power and flexibility for professional audio installations. With its impressive output of 4 x 800W at 4 ohms, the IA3204D is perfectly suited for both constant voltage (70V/100V) and low-impedance applications. Whether you're managing a large conference room, theater, house of worship, or event venue, the IA3204D ensures robust, consistent audio performance. The amplifier's versatility extends to stereo and bridge configurations, offering flexibility for a wide range of audio requirements. It is ideal for sound reinforcement in demanding environments where high power, precision, and reliable performance are essential.

One of the standout features of the IA3204D is its integrated DSP, which enables advanced audio management with precise control over signal processing. It offers several preset configurations, including a flat mode, dBTechnologies speaker presets, and user-defined options, giving sound engineers the flexibility to tailor the amplifier's output to the specific needs of the venue. The full-range power supply with power factor correction (PFC) ensures efficient power delivery, while the GPIO interface allows seamless integration into larger audio systems. The IA3204D also includes Dante networking, providing digital audio inputs and enabling remote management and monitoring, making it a powerful tool for modern audio installations.

The compact 1U rack design of the IA3204D makes it easy to integrate into existing rack-mounted setups, while the robust construction ensures durability and longevity. The amplifier features balanced analog inputs and Dante channels for output, with two RJ45 Ethernet ports for networking, allowing for seamless integration with Dante-enabled devices and AuroraNet for setup and control. Its performance specifications include a frequency response from 20Hz to 20kHz and support for a wide range of speaker impedances, making it an adaptable and efficient solution for various speaker systems.
