DAP TA-4.750

DAP TA-4.750 – 4-Channel Touring Amplifier with FIR DSP

The DAP TA Series represents a new generation of high-performance touring amplifiers for professional live sound and fixed installations. Lightweight, compact, and built on a high-efficiency class-D architecture, TA amplifiers feature a fully equipped DSP engine including 512-tap FIR filters, 8-band parametric EQ, input and output delays, and advanced dynamic processing. Engineered for today’s demanding stages, they deliver powerful, accurate and reliable audio reproduction with exceptional signal-processing flexibility. Equipped with a universal 100–240 V power supply with active PFC, every TA amplifier operates worldwide with high efficiency and reduced heat dissipation.

The built-in DSP can be configured via the front LCD screen and multifunction encoder, or fully controlled through a PC software suite (Windows 10/11) offering detailed access to all parameters: FIR, EQ, limiters, delays, 4×4 routing, phase, high-pass/low-pass filters, user presets and real-time IP monitoring. DAP also provides ready-to-use DSP presets for Odin, WMS and NRG passive systems, ensuring quick deployment and optimal performance.

The TA-4.750 is the high-power mid-range model of the TA lineup. Compact (1U), rugged and designed to handle loads as low as 2 Ω, it delivers 4×750 W @4 Ω and up to 2600 W in 8 Ω bridge mode (20 Hz–20 kHz). With over 90% efficiency, outstanding stability and a feature-rich DSP, it is an ideal solution for touring providers, live-sound reinforcement, and high-power professional installations.
