Feature

◪ Based on the KSA sound and performance, a high-performance precision power amplifier is introduced.
◪ The appearance is novel, the craft is exquisite and the quality is reliable. From the overall design to the most subtle part, the LA series' superb craftsmanship reflects the commitment to quality and performance. Its expressiveness to sound quality inherits our consistent style, and its stability is perfect.
◪ Perfect protection circuit. The stability of the whole machine depends on the advanced and complete protection circuit.
The protection circuit of the LA series not only stays on the DC protection of the speaker, but more importantly, it adapts to the harsh working environment and can work easily. The LA series uses a perfect temperature-controlled protection circuit, which perfectly solves the fatal damage caused by overheating. When the internal temperature reaches 90 °C, the amplifier will automatically cut off the connection with the speaker. When the temperature drops back to 88 °C, the amplifier will automatically resume and work normally.
The short-circuit protection function of the LA series ensures that the engineer can protect the machine itself and the speaker safely and reliably under misoperation or other accidents.
◪ Limiter: It is a protection circuit that is very effective in preventing damage to the speaker. When the power amplifier is clipped and overloaded, a large amount of harmonic energy is generated, which overloads the speaker and damages it. For this reason, a nonlinear comparator is specially set in the LA series power amplifier. Once the signal is found to be clipped, the working state of the power amplifier can be adjusted immediately until the clipping is eliminated.
◪ Excellent audio performance: LA series amplifiers have excellent signal conversion characteristics. He has very small harmonic distortion (THD), intermodulation distortion (SMPTE-IM), and transient intermodulation distortion. Innocent, natural sound quality is the perfect music.
◪ Boot delay, shutdown mute anti-shock protection. The speaker is protected from strong inrush current and noise is generated.
