Putting the HE 1 into operation | Using the tube headphone amplifier connected to a Mac/PC 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 adaptation 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 default audio output device: ▷▷ Install the "HE 1 USB Audio Software Package" from the USB flash drive (supplied). The software package can also be downloaded from the Internet at www.sennheiser.com/download or be obtained from your Sennheiser partner. You need administrator rights for installation. 20
