DESCRIPTION


The Q-Series is designed for the most quality demanding live audio users, whether in touring rigs or fixed installations. For those users, who simply want a high performance amplifier to go with their existing processor or console, the Q-Series amplifier is an ideal choice, offering high power, reliability and zero signal latency. Q-Series amplifiers are based on TD class topology. This topology almost uncompromising combines the best features of switching and analog amplifiers - high efficiency of switching and high quality sound of analog amplifiers.

Q-Series amplifiers have switching power supply. Each channel is powered from separate power supply. This allows to continue working in case of failure of one of them. The amplifiers use separate for each channels over sized forced cooling system. The amplifiers can stable work on 2 Ohms load resistance at ambient temperatures up to 50 degrees. The cooling system uses 4 powerful MagLev fans, the intensity of which changes smoothly depending on the output stage temperature. Specifically for use in hard touring conditions amplifiers are equipped with reliable protection against high mains voltage. Even the connection to the ~380 V mains will not damage the amplifier! No switchable parts inside this amplifiers what will ensure high liability on the long term. To protect the amplifier from ingress of dust and foreign objects, amplifiers have a dust filter made of polyurethane foam. The amplifier is equipped with a full set of modern protection systems; short circuit protection, thermal protection, DC and high frequency speaker protections.
