Harmonai DA-206 2-in/6-out digital audio processor product image

Product Overview

The Harmonai DA-206 is a professional 2-in/6-out digital audio processor, engineered for precise management and optimization of multi-channel audio systems. It delivers a 105dB dynamic range and ultra-low 0.01% THD distortion. Each input channel features 15-band graphic EQ and 9-band parametric EQ filtering, while each output channel offers 8-band parametric EQ—enabling full-spectrum, surgical tonal control. Every output includes an independent high-pass/low-pass filter with selectable Butterworth, Bessel, or Linkwitz-Riley response curves (6/12/18/24/48 dB slopes), plus a fully adjustable limiter with user-defined threshold, attack time, and release time (2×, 4×, 8×, 16×, or 32× attack)—meeting the most demanding requirements of professional sound reinforcement.
