Description

Product Details:

The appearance of AMPX-50 is based on the design language of Jeff Rowland Model 10. The amplification circuit uses 3 STK404-120 modules per channel in parallel, The sound is warm, delicate, smooth, and non irritating, with low distortion and low background noise. The strings are full of charm, combining strength and softness.
.
● The silver aluminum alloy chassis presents a three-dimensional light and shadow hierarchy and floating visual sense.
● Referring to Jeff Rowland Model 10 design, with 250W high-power output and ultra-high damping coefficient.
● Ultra large current reserve, abundant energy, and effortless large dynamics.
● After parallel connection, the output impedance significantly decreases and the damping coefficient skyrockets.
● Multi module error averaging effect, resulting in lower distortion.
● The total power consumption is distributed among three modules, which disperses heat and makes long-term operation more stable.
● Single module redundancy design allows for normal operation even if a single module is abnormal, resulting in longer amplifier lifespan and lower failure rate.
● Two 400W toroidal transformers are independently powered, and the left and right channels do not interfere with each other.
● CA3420AS operational amplifier, Omron relay for horn protection.
● Equipped with a startup soft start circuit, gradually increasing the voltage to avoid startup surge current, protecting the rectifier bridge, filtering capacitor, and audio equipment.
