Description

The DAP TA-4.750 is a powerful and compact 4-channel Class D DSP amplifier designed for touring professionals and demanding installations. With 4 x 750 W at 4 ohms and full 2-ohm stability, this amplifier delivers high output and efficiency within a space-saving 1U rack unit. Advanced DSP control via free PC software (Windows 10/11) allows complete system customization including 8-band parametric EQs, FIR filtering, routing, limiters, delays, and more. Real-time monitoring of voltage, current, and thermal status is supported via network, and a built-in network switch enables daisy-chaining multiple amplifiers. Ideal for high-current, low-impedance speaker loads, the TA-4.750 features a rugged steel chassis, LCD control screen, and a universal SMPS with active PFC for global use.
