Two Channel Professional Class-D Amplifier
SP-DX225(2×250W@8Ω), SP-DX235(2×350W@8Ω)
SP-DX260(2×600W@8Ω), SP-DX280(2×800W@8Ω)
Description:
The SP-DX2 series digital amplifier is a two-channel classical professional amplifier, it has inherited the high reliability and high applicability of anolog amplifiers, as well as added the digital modulator circuit. It designed of switching power technology, whose advantages are without transformer for less heat generation and long life span. With a small size, it delivers big output power and outstanding sound. SP-DX2 series includes five models for your choice: the biggest model deliver RMS 2*800W/8Ω 2*1800W/4Ω with a weight of max. 7kgs. This series applied the classical PWM circuit design and excellent protection circuit. It has high reliability and applicability, big dynamic range, small size, light weight, high efficiency, low distortion, big output power, Etc. Higher efficiency of more than 85% decrease the power electricity consumption and protect green environment.
This SP-DX2 series applied excellent power-supply design, reliable circuit, high efficiency, low distortion. It has
outstanding amplification part. After years' handwork of R&D, we succeed to develop the new circuit topology. The
music signal becomes more refined digital signal after the new modulation system. The new modulation mode helps to
taking sample of extremely small signal, improve and perfect the method of taking samples. High switch mode
frequency, precise controlling of dead-time, makes the distortion of the amplifier much lower, the sound quality reaches
even passed the one of traditional transformer amplifier. This series used refined materials, used the Sanyo fans from
Japan making the noise much lower.
This SP-DX2 series designed for cinema systems, smart homes, and home theaters, also ideal for meeting room, stadium, bar, theme park and train station indoor and outdoor sound system, capacity of maximum connection of six professional sound low impedance loudspeakers.
