The ES series from YME Audiotechnik is a range of professional Class D power amplifiers comprising models ES 7A, ES 9A, ES 11A and ES 13A. These devices are intended for use in professional sound systems for concert halls, clubs, theatres, recording studios and large‑scale events. ES amplifiers deliver high output power from 800 W to 2800 W per channel depending on the model and load impedance. They feature reliable switching‑power technology and a compact rackmount design for integration into professional audio setups. With a wide frequency range of 20 Hz–20 kHz, low distortion and high signal‑to‑noise ratio, these amplifiers are suitable for reinforcing both musical programmes and speech in sound reinforcement systems.
