AT432-D

Garvan Acoustic AT432-D - 4-Channel Installation Amplifier with DSP and Dante™/AES67

The Garvan Acoustic AT432-D is a professional 4-channel installation amplifier delivering a total output of 320W, designed for modern AV systems. It supports speaker loads from 2Ω to 8Ω per channel, allowing flexible integration with various loudspeaker configurations.

Equipped with a built-in DSP processor, the AT432-D offers precise audio control through parametric EQ, crossover filters, and limiters for overload protection. With Dante™ and AES67 network interfaces, the amplifier integrates seamlessly into IP-based audio systems, enabling low-latency, high-quality multi-channel transmission.

The unit features balanced inputs (Euroblock 3.8 mm) and unbalanced inputs (stereo mini-jack, parallel to inputs 1 & 2), providing versatile connectivity. Its wide frequency response (20 Hz - 20 kHz ±0.5 dB), high signal-to-noise ratio (>100 dB), and excellent crosstalk performance (-60 dB at 1 kHz) ensure pristine audio reproduction.

Powered by a universal regulated switching power supply with Power Factor Correction (PFC), the AT432-D offers efficient energy usage. Its sealed, internally cooled design ensures quiet operation (max 30 dBA), even under heavy load.
