It adopts full balance amplifying circuit to reduce interference

and provide better music playback effect.

Differential Circuit 

Amplifying Circuit

three-stage BTL differential output

Amplifying Circuit

three-stage BTL differential outpu

Class A/AB Mode Auto Switch

Class A /AB Mode

Auto mode: It will auto-switch to Class A or Class AB mode according to the machine temperature. It can also be adjusted manually.

Bi-wiring Design

For less interference, sound coloration and distortion.

Bi-wiring may produce an audible improvement

over standard single cabling, reduce magnetic interaction in the cable and result in better sound.

Hi-power Transistor

8 pairs TTC5200/TTA1943 high power transistors

It adopts well matched high power TTC5200/TTA1943 transistors,

which are very sensitive and work stably for high-speed switching even when the working current changes a lot , so as to reduce impact on sound quality.

180,000μF Capacitance

1,200W Transformer

Well package, low noise & high power.

Separate Chamber Layout

For less interference and better channel separation.

Multiple separate chambers for each function area

work well to reduce interference and noise.

Wide Voltage Patents

Patent No.1: high and low voltage power

supply switch used for audio amplifiers

The designer sets a reference voltage inside compared with the amplified audio signal. It will output the corresponding level to the conversion control circuit. The conversion control circuit selects the on-coil according to the input level to realize the high and low voltage conversion, while preventing the sudden jump of the level and distortion that occurs in the Class H power amplifier. With this stable and reliable design, the whole machine gains high efficiency and better energy saving, improving the performance of the power amplifier.

Patent No.2: power supply switch

used for audio amplifiers

Basic circuit components for 110V & 220V conversion.

When the voltage exceeds the preset limit,

it can avoid misjudgment of power supply,

and prevent excessive voltage and damage.

The circuit conforms to voltage

in most countries and regions.

1W standby, more energy efficient.

External Design

It is classic black and white and all aluminum with sleek and uncompromising design which embodies its noble beauty. Just as our design concept: we render audio products noble.
