The Pulz RS-900 Classic two-channel power amplifier from the Classic range is a robust bipolar output circuit which combines clean power with superb dynamics and can accurately drive a variety of speaker systems, in both active and passive modes.
The power supply consists of a heavy-duty high current toroidal transformer and large capacitor banks that deliver continuous power without hiccups when driving low impedance speakers. The high-power bipolar devices and the forced air-cooling ensure stable operation in typical projection boots. The topology consists largely of discrete components for long-term reliability. The modular construction facilitates field serviceability. The front panel features signal presence, clipping, protect and thermal status indicators. The amplifier is fully protected against internal and external malfunctions. The RS-900 Classic is housed in a heavy-duty 3U rack mountable chassis. The front to back forced air-cooling facilitates direct stacking, saving valuable rack space.
The exceptional sturdy construction makes the Pulz RS-900 Classic an investment that guarantees many years of trouble-free service.
