SONY Portable Headphone Amplifier PHA-2A
Product Description ★ Adopt a headphone balance terminal of Φ4.4mm. Portable headphone amplifier to enjoy the high quality of the balance connected easily ◆ Corresponding to Φ4.4mm balance connection ◠It is a JEITA unified standard φ4.4 balance standard plug of adopting the headphone balance terminal. L / R positive phase each of the channel (+), reverse phase (-) improve the separation keeps the ground by configuring to clean in two amplifiers with an output of. S / N improvement by reducing the effect of power source line noise by to achieve a sense of localization and sharpness. ◆ USB audio support (PCM: up to 192kHz / 32bit, DSD: 2.8MHz, 5.6MHz) ◠When the USB audio connection adopts the asynchronous transmission mode (Asynchronous), PCM: up to 192kHz / 32bit, DSD: corresponding to 2.8MHz / 5.6MHz. USB Audio IC and DAC, each has its own clock, achieve a high-quality sound by maximizing eliminate the influence of the jitter of the clock on the transmission side. To reproduce the very best the power of high-quality content. ◆ High quality DAC (ES9018K2M), high-quality headphone amplifier (TPA6120) equipped ◠The DA converter, adopted ES9018K2M from the point of view of the S / N and anti-jitter performance. In addition, the voltage amplification part, has adopted a high-quality LME49860 of low noise and low distortion. And, like the output stage equipped with double the TPA6120 of current feedback type high slew rate amplifier IC, corresponding to more of the high-quality sound by adopting a semiconductor device that has top priority to quality. Furthermore, by OCL output stage in accordance with the positive and negative 2 power supply system, it is possible to drive the headphones to the high quality and powerful.
