The Barix RetailPlayer S400/SP400 is an audio over IP decoder which includes an amplifier to drive a loudspeaker. While S400 requires a power supply unit to operate, the SP400 needs PoE (IEEE 802.3af) to power up.


STEP 1 Connect the audio output

Identify the 3.5mm (1/8") standard stereo mini jack output. Using a "Y" type audio cable it is possible to connect the Left and Right channels to an amplification system.

STEP 2 Connect network

Connect your device to the network. For SP400 - This is the only connection required, device will boot when PoE is successfully negotiated with the switch

STEP 3 Connect power

For S400 use the provided power supply to power up the unit. When the device boots:

  • Right after power-up status LED is red (boot in process)

  • 20s after power-up → Device announces its IP Address (take note to be able to enter the web interface later) → LED turns from red to green

  • 40s after power up → Application is ready

RetailPlayer S400/SP400 is ready to be configured. Refer to the Quick Install Guide for a fast introduction on how to connect the unit with the Portal and play music.
