ALPINE PDR-F50 – 4-ių kanalų garso stiprintuvas
The PDR-Power amplifiers offer the best performance in their class, redefining expectations in the high-power compact amplifier category. Thanks to trickle-down technology, our in-house engineering team has taken many of the patent-pending technologies introduced in the industry-leading PDX series and infused them in the new PDR-Power amplifiers. The PDR-Power amps provide you with the absolute widest bandwidth, best signal-to-noise, lowest distortion and highest damping factor of any amplifier in their class without sacrificing power.
