Harmonai DAP48 4-in/8-out digital audio processor product image

Product Overview

The Harmonai DAP48 is a powerful 4-in/8-out digital audio processor designed for professional audio systems. Each input channel features 31-band graphic equalization (GEQ) and 10-band parametric equalization (PEQ), with center frequencies spanning the full 20 Hz–20 kHz range, gain adjustment from ±20 dB in 0.1 dB steps, and Q values from 0.404 to 28.8—enabling extremely precise tonal shaping. Each input channel includes independent delay control ranging from 0–1000 ms: resolution is 21 μs for delays under 10 ms, and 1 ms for delays above 10 ms—achieving microsecond-level precision. Each output channel can be individually routed to any single input channel or combination of input channels, offering highly flexible signal routing. Output processing includes 10-band equalization (with selectable PEQ, low-shelf, or high-shelf modes) and professional crossover filters (LPF/HPF), supporting Linkwitz-Riley, Bessel, and Butterworth filter types with selectable attenuation slopes of 12, 18, 24, or 48 dB/octave—making it an ideal digital audio processing solution for professional sound engineering, live sound reinforcement, and large-scale venues.

Typical Applications

The DAP48 is ideal for professional sound systems, live sound reinforcement, large venues, theaters, conference centers, and any environment requiring precise audio signal processing. Its 4-in/8-out configuration supports multi-zone and multi-speaker system signal distribution. The 31-band GEQ + 10-band PEQ on each input enables sound engineers to precisely correct room acoustics and loudspeaker frequency response anomalies. Microsecond-accurate delay control ensures phase coherence across multi-loudspeaker arrays. The 10-band output EQ combined with professional crossover filters allows precise matching to full-range, subwoofer, and high-frequency loudspeakers. With three selectable filter types (Linkwitz-Riley, Bessel, Butterworth) and four attenuation slope options, the DAP48 delivers optimal crossover performance for diverse applications.
