Wireless Audio Receiver for Streaming

The Betrusami Bluetooth 4.0 audio receiver adds wireless streaming to any sound system with RCA or 3.5 mm inputs. It pairs with smartphones, tablets or computers and draws power from the included AC adapter or USB cable. The unit is designed solely as a receiver, not a transmitter.

Upgrade from Wired Auxiliary Cables

This adapter replaces a physical audio cable between a source device and a speaker or A/V receiver. The jump is worth it when you want to control playback from up to 15 metres away without running wires across a room or vehicle. It also suits older stereos that lack built-in Bluetooth.

15 Metre Range with Stable Signal

The receiver maintains a reliable link up to 15 metres (50 feet) in open space, though practical range may drop to around 35 feet with walls or interference. It handles high-quality audio streaming for music and media playback. The single-device pairing and auto-reconnect simplify daily use, but multi-point connection is not supported.

Questions about this item

What cables and jacks does the Betrusami receiver need to connect to my speakers?

It ships with a 3.5 mm to RCA cable and accepts standard RCA or 3.5 mm jacks on any powered speakers or A/V receiver.

How do I pair the adapter and what is the step people often miss?

Press the single pairing button once, then select the receiver from your phone or tablet's Bluetooth 4.0 menu; the step many miss is confirming the connection on the source device before streaming.

Will the power supply or Bluetooth module need replacing later?

The unit runs from the included AC plug or USB power cable, and the Bluetooth 4.0 receiver itself has no user-serviceable parts or scheduled maintenance.
