Product Details

Technical Features

The AK380 AMP supports 8.1 Vrms output when connected via high-gain balanced output. High-gain output is four times greater than low-gain output and supports high-impedance headphones. An amplifier, which increases audio output, consumes a great amount of energy. Thus, the AK380 AMP features a 3400 mAh large-capacity battery - identical to the AK380 itself - to support up to nine hours of continuous unbalanced-output playback.


The AK380 AMP was designed as an extension of the light and shadow theme of the AK380. The amp retains the subtle changes and details in the emitted brilliance as light flows across its surface. The diamond pattern engraved into the volume wheel of AK380 is repeated on the amplifier's rear light for design continuity. The area of the amplifier in contact with the AK380's volume wheel reproduces the design's angle of reflection for comfortable wheel operation. The amplifier's light shining delicately through the gaps in the reflected surface visually accentuate the music's mystique.

Other Functions

To protect earphones/headphones during high output, the volume is automatically adjusted when the amp is powered on or the earphones/headphones are disconnected. Furthermore, the gain can be easily adjusted via the AK380's settings.
