Harmonic Design QT 12 ETH Touring Amplifier - 4 x 3000w, 196KHz DSP,FIR, Dante, Ethernet, AES3Specially optimized SMPS with PFC for extreme continuous loads, 4 power outputs up to 3000W @ 2 Ohm or 4 Ohm4In/4Out High-End HD Multi DSP, Multi-stage limit

The Harmonic Design hd QT12-ETH is a pinnacle of German-engineered power and signal processing. Delivering a staggering 4 x 3000W, this Class-D powerhouse is designed for extreme continuous loads in professional touring and high-capacity installations.

At the heart of the QT-ETH series is an industry-leading 192 kHz native sampling rate, paired with 32-bit ADC/DAC converters. This ensures that even at maximum output, the audio remains linear, transparent, and high-fidelity. Whether you are driving large-scale line arrays or high-performance subwoofers, the QT12-ETH provides the "hold time" and energy needed for unparalleled low-frequency reproduction.

The hd QT12-ETH isn't just an amplifier; it is the command center of your sound reinforcement system. Designed to deliver "power × hold time," it ensures that kick drums stay punchy and vocals stay crystal clear under the most demanding touring conditions. If you are spec'ing a world-class system in Ireland, the QT12-ETH offers the headroom and digital sophistication required by modern pro-audio standards.
