Approximately The Product
Prefer sound quality, seek reproduction, multi-operational serial thrust, selects two operational amplifier sets (OPA2604AP+OPA2107) featuring good sound quality and large thrust provided by American famous BB, with superb effect, the small-sized distinct dual-power boosted circuit carefully researched by engineer upgrades the transparency of OPA2604 to the highest grade of amplification effect. Power is the key to producing good sound from the portable headphone amplifier, and power supply adopts the complex and costly dual-power design. Among so many single-power headphone amplifiers available in the market, high-quality high-current positive-negative power supply is absolutely considered as the "master grade". Through partitioning, headphone amplification is kept far away from the power supply to solve the possible electromagnetic interference caused by power boost. Ultra-small-sized audio filter capacitor array + LC type filter circuit reduce the system ripple to the minimum, providing clean and high transient power to the headphone amplification circuit. As a headphone amplifier with the strongest sound quality, is featured by high SNR, delicate and transparent sound quality and large thrust. Headphone fans are often experient that, although headphone is the nearest acoustic device to human ears, even the distance from common in-ear buds to the eardrum is only 1-2 cm, in most cases, the sound is heard to be obscure, as if the glass cannot be properly cleaned, it sounds a bit unclear, A933 will free you from this concern.
This product uses quadruplex potentiometer to regulate the volume, the power switch is provided by Japan ALPS, the power relay is provided by Japan NEC to offer dual protection on the output circuit, prevent impact sound and protect the headphone.
