Product information
1. Prefer sound quality, look for playback, multi-op serial thrust, A935 selects two sets of op-amps (OPA2604AP + OPA2107) characterized by the good sound quality and a great boost provided by the famous American BB, with a superb effect, the double distinguished of small size The power enhanced circuit carefully studied by the engineer improves the transparency of OPA2604 to the maximum degree of amplification effect. Power is the key to producing good sound from the portable headphone amplifier and the A933 power supply adopts the complex and expensive dual power supply design. Among the many single-power headphone amplifiers available on the market, the high-quality A933 high-current positive-negative power supply is absolutely considered the main grade. Through partitioning, headphone amplification is kept away from the power supply to resolve possible electromagnetic interference caused by the power boost. The extremely small audio filter capacitor array + LC type filter circuit minimizes system ripple, providing clean, high transient power to the headphone amplifier circuit. As a headphone amplifier with the loudest sound quality, A935 is characterized by a high SNR, a delicate and transparent sound quality, and a great boost. Headphone fans often have an experience that although headphones are the closest acoustic device to the human ear, even the distance from common in-ear earphones to the eardrum is only 1-2 cm, in most cases the sound is obscure, Since if the glass can not be cleaned properly, it seems a little unclear, A933 will free you from this concern.

2. This product uses a quadruplex potentiometer to adjust the volume, the power switch is provided by Japan ALPS, and the power relay is provided by Japan NEC to offer double protection on the output circuit, Prevent impact noise and protect headphones. Its power supply is added with the exclusive charging function, which can charge other smart devices and produce a 1A current.
3. Burn-in information: Our expected design effect is only achieved after burning the product for some time. For headphones and speakers: burn-in is required for 96 hours; for amplifiers and other devices: burn-in is required for 24 hours, Burn-in mode: Select continuous burn-in or cumulative regular use.

Perks
1. Improved sound quality: maximum sound quality, let time try everything, make sound transparent, awaken musical inspiration, new design concept, more than imagination, three-partition isolation circuit, main power supply, two sets of op-amps (OPA2604AP + OPA2107AP) provided by US Famous BB, it is warned that the /bass ups significantly increase by one level after multi-op serial connection to the product, which benefits from the high internal voltage of +/- 7.5 V to greatly improve thrust.
2. Detail reproduction: The product can capture more details that are not the extra addition to the product but the existing ones because the non-professional headphone amplifier often has such details.
3. Increased sound field: anyone who does not use a good headphone amplifier may never understand the sound field better, it is a sense of presence, the sense of the scene heard by a transducer headphone is different from that added to the product, It is worth noting that a good headphone amplifier deserves a good headset.
4. Cell phone backup power: unique product design (mobile phone charging) can be used as a backup power supply
