DAP TA-4.3400

DAP TA-4.3400 – Ultra-high-power 4-channel touring amplifier with FIR DSP & 70/100 V modes

The TA-4.3400 is the most powerful model in the DAP TA touring amplifier series. Delivering an impressive 4 × 3400 W at 4 Ω, supporting extreme 2-ohm loads, and reaching up to 11,500 W in bridge mode (1 kHz), it is designed for maximum output and reliability in the most demanding applications. Supporting both Lo-Z systems (2/4/8 Ω) and 70/100 V high-voltage lines, it is a premium solution for large line-array systems, professional touring setups and high-power fixed installations. Its compact 1U chassis combined with a high-efficiency Class-D architecture (>90%) guarantees exceptional performance, stability and energy efficiency for large-scale productions.

The fully integrated DSP, controllable over IP via Windows 10/11 software, provides extensive processing: input delays (100 ms), output delays (30 ms), 8-band parametric EQ on input/output, HP/LP filters (Bessel, Butterworth, Linkwitz-Riley), FIR processing up to 512 taps, internal 4×4 mixing matrix, peak and RMS limiters, phase inversion, user presets and full network supervision (voltage, current, temperature and protection status).

Its universal SMPS power supply (100–250 V AC) with active PFC and Soft-Switching technology ensures optimal efficiency, stable operation and maximum reliability even under challenging electrical conditions. The 3" LCD display with rotary encoder provides quick and intuitive access to all parameters, ideal for touring technicians and rental professionals.
