Features:
100% Brand new and high quality!
A928 adopts the embedded high-power control chip system imported from US，
with the front-end non-balance to balance， back-end balance transmission amplification， and a wide application of voltage.
1: The front-end adopts the non-balance to balance circuit， which can control the distortion of IC，
with high fidelity of sound reproduction and great dynamics
2: Tailored for digital power amplifier， power is supplied in a state of high frequency，
this product contains a lot of imported elements in parallel assembly，
high-frequency low-impedance that comprises a ultra-high power digital amplifier
This product adopts the top brand IC with tube tone for enthusiasts:
Tube + Warm Sound + high-efficiency digital amplification rationally blended with special tuning.
Music notes are dancing in your ears.
Powerful， high dynamic， good strength， full voice，
wide sound field and powerful low-frequency show considerable thickness.
Magnetic， fine and full voice. High frequency shows good performance.

Additional Information:
1. Signal input first-in:
Original manufactured by the well-reputed National Semiconductor which delivers the warm and fine sound quality with no annoying sound，
establishing the overwhelming tubing effects of this amplifier.
2. No sound interrupt when pushing 4Ωconsole，
MOS tube functions as the switch tube， with fine sound quality， loudspeaker protection， shielding impact from the startup and shutdown，
overcurrent and short-circuit protection. Its effect is much better than loudspeaker protection circuit of the relay.
3. Allows fingertip operations on portable devices including listening to music， playing games and watching movie.
