audio technica / ATHA26D

It is a headphone amplifier.

■Headphone amplifier with built-in D/A converter
■Equipped with an optical digital input for high-purity sound reproduction. This amplifier features a built-in D/A converter that supports 24-bit/192kHz.

■Uses a high-performance D/A converter (AK4396) that supports 24-bit/192kHz.
■Equipped with a high-quality optical digital input that supports 192kHz.
■Equipped with a line output, it can also be used as a high-quality D/A converter.
■The high-rigidity aluminum alloy body and die-cast front panel suppress unnecessary vibrations. This suppresses distortion and unnecessary vibrations generated by the unit itself, achieving high sound quality.
■Uses carefully selected acoustic parts for high-quality sound reproduction. The capacitors and operational amplifiers that are responsible for high-quality sound reproduction use carefully selected acoustic parts, improving resolution and sound reproduction.
■Equipped with a low-noise, low-distortion headphone amplifier for clear sound reproduction.
■FET input reproduces even the most delicate details with low noise.
■Power transistor output system provides ample sound reproduction.
■Uses a high-capacity AC adapter to achieve rich bass reproduction with high-output headphones.
■Equipped with a signal indicator that allows you to check the optical digital input signal.
■An optical digital signal through-out function is convenient when building or expanding an AV system.
*Earphones/headphones with mono plugs cannot be used.
*Bitstream signals such as 5.1ch surround cannot be played. Please set the audio output setting on your player or other device to linear PCM signals (2ch stereo signals) before playback.
