Denon HEOS Amplifier HS2 – 2-Channel Wireless Stereo Amplifier with HEOS®
The Denon HEOS Amplifier HS2, also known as the HEOS Amp HS2, is a compact network stereo amplifier designed to add HEOS® wireless multi-room streaming to a pair of passive loudspeakers. Delivering 100W + 100W into 6Ω or 70W + 70W into 8Ω, it combines powerful Class-D amplification with dual-band Wi-Fi, Ethernet, Bluetooth, USB, analogue and optical digital connectivity. High-resolution audio support, Dolby Digital/Dolby Digital+ decoding and a dedicated subwoofer output make it suitable for both standalone stereo systems and HEOS multi-room installations.

System Integration
The Denon HEOS Amplifier HS2 is designed to convert a conventional pair of passive speakers into a network-connected HEOS audio system. Connect the speakers directly to the amplifier, then access music through Wi-Fi, Ethernet, Bluetooth, USB, analogue or optical digital sources. A powered subwoofer can also be connected through the dedicated subwoofer output for a 2.1-channel system. Multiple compatible HEOS products can be grouped through the HEOS app for synchronized multi-room playback.
