Power amplifier QT12-ETH Class-D 4x3000W 4Ω Dante AES3 2U - HARMONIC DESIGN HDE-5005

4 × 3000 W into 4 ohms Class-D power amplifier for touring applications. In just 2U rack space, this power amplifier delivers reliable high performance day after day. It is the ideal “control center” to get the best possible performance and linearity from Harmonic Design PA systems. In addition to the 4 analog inputs, it has AES3 and Dante digital audio inputs. It is based on a switch mode power supply specially optimized for maximum long-term performance, providing high energy for the best reproduction especially of low-frequencies. A generously sized cooling system with temperature-controlled fans allows full load operation with minimal noise production.The user interface consists of an LCD display with navigation buttons for visual information and quick access to key functions such as preset selection, routing matrix, delay and gain. An Ethernet port, in place of the USB present on the QT12 model, is used to connect to the proprietary hd LevelZ software suite for complete system planning, simulation, management and system tuning of all Harmonic Design loudspeakers, from 2.1 active systems to large sound reinforcement systems, and offers maximum freedom in sound shaping and speaker management. The hd MultiDSP combines IIR and FIR filters to create perfectly linearized phase curves and significantly improved impulse responses for a more natural, transparent and realistic sound experience.
