The Pulz PZ4820 four channel power amplifier is specially designed as a cost effective solution for today's competitive environments. The robust bipolar output circuit combines clean power with superb dynamics and can accurately drive a variety of speaker systems, in both active and passive modes. This amplifier is an ideal solution for today's immersive audio installations which require many channels of high power amplification.
The power supply consists of 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 under harsh conditions. The topology consists largely of discrete components for long term reliability.The modular construction facilitates field serviceability.
The front panel features signal presence, clipping, fault and output level indicators. The amplifier is fully protected against internal and external malfunctions. The Pulz PZ4820 is housed in a 2U rack mountable chassis. The front to back forced air cooling facilitates direct stacking, saving valuable rack space.
The exceptional price to performance ratio combined with sturdy construction makes the Pulz PZ4820 an investment that guarantees many years of trouble free service.
