XD-Series are modern amplifiers for professional entertainers, who require maximum performance and sound quality on a limited budget.

XD-Series amplifiers are based on a modern, high-performance D class topology. This topology provides high efficiency, low heat generation, large output power and together with a switching power supply – light weight and small dimensions. The amplifiers use forced cooling system common to all channels. The airflow direction is front to back. The cooling intensity changes smoothly depending on the output stage temperature and ensures the efficient operation of the amplifier at high ambient temperatures. To protect the amplifier from ingress of dust and foreign objects, amplifiers have a dust filter made of polyurethane foam. The filter is located under the easily removable front panel. Due to its structure, the filter material allows repeated washing and flushing. For cleaning the filter it is enough to remove the 4 fixing screws. The amplifier is equipped with a full set of modern protection systems. These include short circuit protection, thermal protection, DC and high frequency speaker protections.
