Microsoft Windows operating system
If you use a Microsoft Windows operating system, you have to install USB
Audio drivers that come with the "HE 1 USB Audio Software Package". After
installation of the drivers, the HE 1 is recognized automatically.
System requirements
• Intel Core 2 processor with 1.6 GHz (minimum) or similar processor
• 2 GB RAM (minimum)
• Microsoft Windows 7/8/8.1/10 operating system (32 or 64 bit)
HE 1 USB Audio Software Package
The software package contains the following components:
• WDM USB audio driver
• ASIO USB audio driver
• Control Panel
• HE 1 Updater
Notes on the USB audio modes
If you use standard software (e.g. Windows Media Player or Apple iTunes),
the best possible transmission mode is limited by the operating system (the
played music file is mixed with System Sounds and adapted to the sample rate
and bit depth set for the WDM driver).
For native reproduction of high-resolution files (without driver-induced ad-
aptation of sample rate and bit depth; 32 bits/up to 384 kHz or DSD files),
you require an ASIO driver and special third-party software, which transmits
the music file natively from the player software to the DAC of the HE 1 (see
page 18).
Example: Microsoft Windows 10
To install the "HE 1 USB Audio Software Package" and to set the HE 1 as the
