Products Detail:

The A6 amplifiers are based on T class amplifier chip “TA2021b” of U.S. TRIPATH Company as the core

 

T-class power amplifier power output circuit is the same as Pulse Width Modulation D-class power amplifier, power transistors is also working on the on/off status, and work efficiently as Pulse Width Modulation D-class power amplifier. The difference is that T-class power amplifier is not using pulse width modulation method. Tripath invented a digital power processing technology called "Digital Power Processing (tm) (DPP (tm))”. It is the core of the T-class power amplifier. It adopts adaptation algorithm and forecast algorithm of small signal processing in communication technology. Input audio signal and entered the speaker after DPP (tm) after digital processing power transistors then used in control of on-off, thus there is no defect of pulse width modulation D-class power amplifier. (T-class is better than D-class)

 

Selection of brand-name components: Japan TOKO inductors, Taiwan GSKD capacitances, Germany EPCOS/KEMET audio capacitors, Taiwan HUI KE relays. All of them are composed with a high quality digital audio amplifier with excellent material, excellent performance, and excellent prices, Songbook audio colleagues sincerely welcome the wholesale cooperation!

 

A6 features:
1.It is small, efficient, energy-saving and environmentally friendly.  It can save electricity about 40% than the traditional class AB audio, in order to avoid the consumption of power caused by long time standby. In real life, many computer enthusiasts don’t turn off the speaker power, 24 hours of work is very power consuming, so A6 is to solve this problem and avoid unnecessary economic waste.

2. A6 amplifier is based on T class amplifier chip “TA2021b” of U.S. TRIPATH Company as the core, then make the sound clear ,the tune correct, the High-Low Pass thick, and the detail rich, and treble in place, while the traditional PC always makes the sound thin, few details. This is the difference between HI-FI digital audio amplifier and traditional PC D class.

 

3.6 MM thick aluminum panels + advanced all-aluminum case + carbon dioxide process + laser tattoo lettering (never off-color).

 

4. Use Genuine Japan TOKO inductors, this inductor owns a two-layer shield protection, reduce EMI radiation, at the same time it plays an important role in deciding the sound good or bad.

 

5. Adopt 8 high current high speed and fast reaction diode to ensure the 2*25W stereo with security.

 

6. Built-in speaker protection and boot-time-delay circuit, avoid the annoying sound of opening and shutting, and protect your expensive speaker.

7. Human start-up, protection and start-up display.

8. Selected brand-name components and original accessories with high quality.

9. Unique large radiator + 15 heat emission holes, ensuring TA2021B chip won’t overheat and works stable.

 

A6 circuit boards:

         

Japan TOKO brand special inductors for digital audio power amplifier is one of the highest standards, with double shielding effect, it plays an important role on quality upgrading.
