  1. 2018 latest version, Treble&Bass independent control, add the subwoofer frequency adjustment, add the pre-amplification.

  2. Bluetooth 4.2 audio input, Perfectly compatible with various Bluetooth devices
  3. Adopted TPA3116D2 amplifier chip as core; MUSE AUDIO or ELNA as input capacitor makes harmonic richer; the top red loop outputs inductor makes its voice purer; Aluminum alloy body is easy to heat-sink; Gilding RAC and crystal terminal looks extravagant. All use genuine components using devices capable of long-term stability.

  4. The total capacity of the capacitor is increased to 4700UF, which makes the signal-to-noise ratio better, the lower frequency is stronger and the energy is more steady.

  5. Can be powered by DC 12~25V. It has 90% high efficiency and lower internal resistance because we used of import seal potentiometer and high speed capacitor array. It can use power switch, storage battery, vehicle power, and so on.

  6. Redesign the low pass filter, the subwoofer is more powerful

  7. The right VOLUME knob turn to end is Shutdown.

  8. Application: it is a very good choice for your home theater system and professional audio system, offers you high level sound and special experience.
