Dynacord S 900 Product Details
The S900 power amp is derived from the Linear Precision topology and offers an extraordinary price-performance ratio without compromising its operational reliability and dependability. Designed as “working horses” and based on the Linear Precision Series amplifiers, the STANDARD PRECISION Series power amplifiers’ efficiency and durability meet the extreme standards of any on-the-road application, providing reliable protection against thermal and capacitive overload, short circuit, and the occurence of HF and DC at their outputs. In addition, special protective circuitry prevents the power transistors from being damaged by Back-EMF. During power-on, delayed switching of the power amplifiers’ power outputs is accomplished via relays. A limiter controls the initial current inrush, preventing the mains fuses from being blown during power-on operation (soft start). Mechanical construction and manufacturing follow the industry’s highest precision standards. The robust steel chassis provides extreme rigidity and is meant to live through any hard wearing condition of touring applications. Thermal stability is guaranteed by two 3-Mode (off / slow / fast) silently running fans allowing trouble-free use of the amplifiers even in a studio environment.
