How to Use
AK HC2 / iOS Adaptor / Manual / Warranty card
Package Contents
USB Type-C Plug
4.4mm Headphone Port (Not compatible with microphones and in-line controllers)
IMPORTANT: Before beginning music playback, check volume level
on playback device and reduce to a minimum level when using AK
HC2. AK HC2 has a built-in amplifier making the sound output
more significant than other devices at the same sound output level.
It is important to start at a low volume level to protect your hearing.
Depending on the playback device you are connecting to, the
volume will default to the maximum output level when the AK HC2
is connected for the first time and each time thereafter. Always
check the volume level on the playback device before use.
The AK HC2 cable should NOT be connected to an Astell& Kern DAP
as the volume will be fixed at maximum output when connected
and cannot be adjusted on the player or AK HC2. Use with the
maximum volume may severely damage hearing. Astell&Kern is
not liable for any damage due to user negligence. Be sure to check
the volume first when using.

1. Compatibility
The product is compatible with most Android-powered smartphones and tablet
PCs, and Windows 10/11 and macOS products. If you use an iOS adapter, you can
connect to iOS-based devices. However, some devices may require additional
manual setup.
The AK HC2 is not compatible with every device. Due to hardware, software and/
or system requirements for some devices, compatibility issues may occur.
Compatibility issues will not be accepted as a reason for exchange, refund or repair.
When connected to a smartphone or tablet PC, the product can play tracks without
any additional driver or application installed. And you can download and use an
additional APP for volume control. Search for [AK HC] and [AK USB DAC] in the
Play Store and install them. These APPs are only supported for Android version.
When connecting the AK HC2 with a Windows PC for the first time, the computer
should recognize the device and the driver should install automatically. If the
computer does not recognize the device or the driver does not install correctly,
the driver can be downloaded from our website.

Connecting to a master device using various conversion adaptors (USB-A, Micro 5
pin, etc.) may cause an unstable connection and other compatibility issues.
The product requires a separate paid/free player to be installed to be able to play
DSD and high-quality PCM audio files on a smartphone.
The AK HC2 cable does not have a built-in microphone. When connecting an
earphone or headphone that has a microphone or in-line controller, the AK HC2
will not be compatible with these functions of the earphone/headphone.
The AK HC2 cable is built for sound output only.
2. Operation/System
The AK HC2 cable does not have a built-in battery. Power is supplied from the
connected device (Android smartphone, tablet PC or computer).
Power consumption may vary depending on the source and file type being played
or the battery capacity of the connected device.
System stabilization for the AK HC2 will be available via firmware updates.
