PL Series 1U Digital Amplifiers
Super compact and lightweight stereo power amplifiers in a 1U rack-mountable housing. Fully digital architecture provides high power output and efficiency with inbuilt protection circuitry. Signal inputs are balanced combo jack/XLR connectors and speaker outputs are provided as locking SPK or 4mm binding posts. Easy portability makes these amplifiers well-suited for mobile sound systems without compromising quality of the audio output.
