HEOS Amp HS2 is made in a small, pleasant-looking case with a simple design and high-quality external finishing. On the front panel of the amplifier with an original diagonal break there is nothing but an LED that illuminates its lower part in a different color depending on the operating mode of the device. Using the three buttons located in the assembly, you can adjust the volume or mute the sound.

Supports compressed MP3 files, WMA files (including purchased Windows Media Player files downloaded from the Internet), AAC (MPEG4 standard), FLAC (lossless) files, and uncompressed WAV files. Native support for 44.1 kHz sampling rate. Support for files with sampling rates of 48 and 32 kHz is possible. Full control of the HEOS Amp HS2, like any other device in the Heos system, is possible using a special mobile application available for iOS and Android. In terms of its network capabilities, the device corresponds to the rest of the Heos components of the updated HS2 series – it plays lossless and High-Res files, including PCM (WAV and FLAC) with parameters up to 24 bit / 192 kHz, and DSD files.
