General Description
The Denon HEOS Link HS2SR, identified by Denon as the HEOS Link HS2, is a wireless network preamplifier designed to bring streaming, multiroom control, and digital sources to an existing audio system. It connects to an integrated amplifier, AV receiver, power amplifier, or active speakers via its fixed or variable level stereo RCA output. In this way, it transforms conventional Hi-Fi systems into modern solutions capable of playing music from online services, mobile devices, USB, local networks, and internet radio through the HEOS platform.
The HEOS Link HS2 integrates dual-band Wi-Fi, Ethernet, and Bluetooth to facilitate wireless source connections. Its HEOS platform allows for controlling and grouping various compatible devices from the app for iOS and Android, sending the same music to different rooms or selecting different content per zone. It also plays high-resolution audio, with compatibility for WAV, ALAC, and FLAC files up to 24-bit/192 kHz, as well as DSD 2.8 and 5.6 MHz.
Connectivity is designed for flexible installation: it offers an RCA input, a 3.5 mm auxiliary input, and an optical input, while its outputs include analog preamplification, optical, coaxial, and a dedicated output for an active subwoofer. The 12V Trigger output allows for switching on an external amplifier in a synchronized manner, and the IR Out port helps control compatible Denon equipment. With its compact size and volume, mute, and status controls on the chassis, the HEOS Link HS2SR is a practical way to modernize home, light commercial, or custom audio systems without replacing their main components.
