Product features

This series is tailored to the application characteristics of the audio-visual (AV) and karaoke (K) system. It features components such as

the top-notch HIFI-grade operational amplifier OP275, customized Sanwa audio large electrolytic capacitors, ON Semiconductor

power transistors NJW21193/21194, and two high-power transformers newly wound with class A silicon steel sheets. The circuit design

boasting an extremely low distortion-to-power ratio and distortion-to-frequency ratio ensures that the sound is delicate and gentle in the

high frequencies, warm and full in the mid-frequency, with strong low-frequency control. The sound is true and natural, the vocals are

delicate and rich, and the overall tone is very balanced.

The product features an electromagnetic shielding and anti-vibration design with galvanized plate. It offers two input options: balanced

XLR female and unbalanced RCA. There is a hidden gain control on the rear panel. It is equipped with a customized HIFI-grade copper

power plug, an oxygen-free copper 3x2.5 square meter dedicated audio power cord with an anti-vibration snake skin net sleeve.

Only the power switch and power indicator are retained on the 8mm aluminum front panel, making the whole product look simple, elegant,

and integrated.

This series of products not only allows you to sing karaoke, but also enables you to experience professional cinema-level acoustic enjoyment.

It provides an extraordinary experience for both music and movies, enough to shake your body, mind, and soul.
