The SMSL PS100 is an ultra-compact audio converter that turns HDMI ARC, optical, coaxial, USB or Bluetooth into a stereo RCA line output (1.9 Vrms), using an ES9023 DAC that accepts up to 24-bit/192 kHz over optical and coax. It's for getting TV or console sound into powered speakers or an amp without an AV receiver.
Who the SMSL PS100 is for
TV owners adding a stereo: HDMI ARC from the TV comes out as stereo RCA, so powered speakers or an integrated amp with its own volume control can play TV and console sound without an AV receiver.
Analog-only amps and second systems: It gives a vintage amp or a pair of powered monitors five digital inputs: HDMI ARC, optical, coaxial, USB and Bluetooth.
Phone streaming to a stereo: The Bluetooth input lets a phone play through the same RCA output as the TV.
Small, USB-powered installs: It draws under 2 W from a USB port and switches inputs with a single button, so it tucks in beside the TV or amp.
Skip it if: you want TV-remote volume, automatic power on/off sync or eARC: the PS100 supports plain HDMI ARC only and must be restarted after the TV is turned off and on again.
