Established in 1995, China THESP Electrical Appliance Co., Ltd. is a professional switching amplifiers manufacturer and wholesale that is concerned with the design, development and production of a diverse range of electrical appliances and home appliances. Our products are selling well in the domestic markets and the overseas markets including Southeast Asia, the Middle East, Europe, USA, Japan, Canda, America and Africa. Also we provide a huge selection of switching amplifiers reviews, compare, manufacturers.

Power supply circuitry utilizes a large custom toroidial transformer in conjunction with large capacitor banks to produce the power to drive the highly efficient amplifier section. High current capability and low output impedance allow the D?100 to drive difficult loads with excellent control, producing 100 watts into 8 ohms and 175 watts into 4 ohms. The mute function puts the amplifier in a standby mode, allowing critical circuitry to be kept powered and eliminate any warmup period. Being over 90% efficient means the amplifier runs cool and extends the life of all internal components, and built-in safety features protect it from shorted speaker cables and components. Built to last a lifetime, our compact amplifier is housed in a heavy gauge steel chassis with 3/16" brushed and anodized aluminum front and rear panels, secured by stainless steel hardware, with highest quality gold plated speaker binding posts. Available with Neutrik single-ended RCA or balanced XLR input, and your choice of gain (26dB/32dB).

This technology helps monitor and correct the amplifier’s output in every switching cycle that is over 400,000 times per second. This not only ensures low distortion but also pristine audio quality. Being true switching Class D Amplifiers, the HD amplifiers draw almost 60% less current from the electrical system of the vehicle. Thus it’s more efficient compared to the conventional Class A/B full range amplifiers. Thus it helps in reducing heat output and the chassis can be made as small as 1/3 of the similar powerful conventional amplifier.
HD600/4 has JL Audio’s Regulated Intelligent Power Supply (R.I.P.S.). Each channel has an independent optimization. It offers advanced thermal management systems. The studio-grade processing features a stackable chassis design. All controls come with a security cover and removable power and speaker plugs.
