Astell & Kern ACRO L1000 at Audiologica

Astell&Kern introduces a new sub-brand of desktop audio products called ACRO. Astell&Kern has taken their expertise in designing best-selling, world-class portable audio devices and put that knowledge in to the first desktop audio product, the ACRO L1000. The ACRO L1000 is the first Desktop Headphone Amplifier from Astell&Kern.

The ACRO L1000 features two AK4490 DAC chips, the same proven performance DACs found in the popular and successful Astell&Kern AK380 players. The Dual DACs deliver proven consistent and high performance digital music playback. With the Dual DAC configuration, the ACRO L1000 delivers superb resolution and rich spatial sound.

The Dual-DAC implementation is re-designed to perform at its best efficiency with the new AMP circuit design in the L1000. This new design allows the ACRO L1000 to deliver master-quality sound with minimal distortion.

Please note. You must lower the volume to zero before connecting any sensitive In-Ear-Monitors or headphones to protect your hearing and your equipment.

When connecting more than two earphones/headphones, the sound is output to the earphones/headphones of the last connected terminal.

When connecting to the XLR balanced terminal, all earphone/headphone jacks on the side of the product should not be connected.
