The IQstream TV supports both Digital Connections (through Fiber Optical TOSLINK/SPDIF connectors) and Analogue Connections (through 3.5mm Audio Jack).
Unlike other Bluetooth Streamers, IQstream TV has both input and output connectors, which allows for seamless integration with your existing soundbar and AV Unit.
For the instructions on how to set up your IQstream TV, please see the IQstream TV Manual.
