Perfect for music on the go, for PC Audio or in a Hi-Fi System

Some digital enthusiasts require small, portable DACs and headphone amps because they’re always on the move from location to location. Others need flexibility with their digital gear, especially the ability to insert a headphone amp into virtually any system and achieve impressive sonic performance. The new ADL A1 headphone amplifier/ DAC is designed for both of these digital enthusiasts – even if they’re the same person!

Hi-Res Audio DSD Decoding

The new ADL A1 is a high-resolution portable headphone amplifier and DAC that can be used with Android devices. The A1 is DSD-capable when used with either Mac or PC. The high-resolution sound that can be achieved through the A1 makes it perfect for portable audio enthusiasts who use the highest quality headphones to delve deeply into a recording. It’s also ideal for those who want to run DSD 2X on either a laptop or a desktop.

While the ADL A1 is certainly small enough to be portable and convenient, it’s also loaded with innovative features such as:

  • USB Mini-B socket for USB A output from a PC/Mac for music and to charge the battery
  • USB A socket for Android music devices via OTG cable
  • Optical and line out that combines a 3.5mm phone jack for line out with a mini-jack for optical output

7.5 Hours of Battery Life

The portable audio enthusiast will also appreciate the A1’s long battery life. While the battery in the A1 lasts approximately 7.5 hours after a full charge, it can be completely recharged in around 5 to 5.5 hours. That provides an exceptional amount of flexibility for playback while on the go. Downtime and scheduling concerns will be minimised.
