PM series products:
The pure analog (class AB) and (class H) inductance circuits are applied, and the independent power supply design for each channel is adopted. In this way, the intermodulation distortion and noise between channels are greatly reduced, and the professional nature of audio power amplifier is also formed.
Class AB - unique power output circuit to make the dynamic range of working voltage, harmonic distortion and intermodulation distortion is smaller, the power output transistor in a perfectly safe range within the scope of work, greatly improving the reliability and stability, signal amplification inductance used high-capacity ring transformer, the output power is more powerful.
Class H - the use of a full range of the latest cooling system design, ensure the best working state of the power amplifier, greatly extend the service life of the power amplifier.With its stability and perfect sound background color, the series of power amplifiers have become the first choice for social professionals.
PM series professional audio power amplifier features:
All series of products have, overload limiter/over-current protection, intelligent temperature control automatic protection/DC protection/RF/overheat protection circuit design, and boot delay launch large current shock protection function, increased the safety reliability of the device itself, and is equipped with two speed low noise fan with thermal control device, make you rest assured，It is widely used in the environment system of language and music.
