MOREGAX Bluetooth 5.4 RCA/AUX Receiver for Stereo Systems

MOREGAX M2R is a Bluetooth 5.4 audio receiver that converts RCA/AUX/USB-equipped stereos and wired speakers into wireless music-playing systems.

If you own a classic receiver, bookshelf speakers, projector with line-in, or any audio gear with AUX or RCA jacks, the MOREGAX M2R gives them modern wireless streaming without replacing your components. This compact dongle plugs into power via Type-C and links to phones, tablets, or laptops so you can send music wirelessly while retaining your existing amplifier, speaker pair, or AV setup. It is a receiver only — not a transmitter — and it also supports USB playback and device charging over its dual USB ports.

How does the M2R connect to my old stereo or powered speakers?

Connecting is straightforward: provide power to the unit, link the provided cable to your stereo’s AUX or RCA input, then pair your Bluetooth source. No configuration menus or apps are required for basic operation, and the M2R supports common analog inputs so it fits most legacy systems.

• Power with the included Type-C cable (no internal battery).
• Use the supplied cable to plug into RCA or 3.5mm AUX inputs on your receiver or speakers.
• Pair any Bluetooth-capable phone, tablet, or laptop to begin streaming.
• Works as a receiver-only device; it won’t transmit audio out to other Bluetooth speakers.

What audio quality and range can I expect from Bluetooth 5.4?

Bluetooth 5.4 brings improved stability and reduced latency compared with older Bluetooth versions, so you’ll hear clearer, fuller sound through your stereo. The M2R is optimized to maintain a reliable link across typical home distances, making it suitable for living rooms, kitchens, and small studios.

• Bluetooth 5.4 for more consistent connections and better signal handling.
• Up to roughly 33 feet (10 meters) of typical indoor range depending on obstacles.
• Supports two simultaneous paired devices for quick switching or multi-user setups.
• USB flash playback bypasses Bluetooth for direct file listening from drives.

Can I charge devices or play USB drives with the M2R?

Yes — the front panel features two USB ports with distinct functions: one plays audio files from a flash drive, while the other supplies charging power to phones or other gadgets. This dual-USB arrangement reduces clutter and offers practical utility beside streaming.

• Left USB accepts USB flash drives for offline music playback.
• Right USB provides power to charge phones and accessories.
• Useful for desktop or AV racks where an extra charger would be inconvenient.
• No internal battery — keeps working continuously when plugged in.

How many speakers and devices can I connect at once?

The M2R supports pairing with multiple source devices and can feed two wired speaker inputs simultaneously via AUX/RCA, allowing you to synchronize audio across a couple of speakers or zones. Note that simultaneous Bluetooth playback between two phones may require pausing the first device before the second begins transmitting audio.

• Pairs with smartphones, tablets, and PCs; supports two active device connections.
• Can drive two old speakers via separate AUX/RCA inputs for synchronized sound.
• Recommended to pause the first device when switching streaming control to the second.
• Ideal for converting legacy speakers into Bluetooth-enabled units quickly.

Who is this for: The MOREGAX M2R is aimed at anyone who wants to keep a favorite stereo, bookshelf speakers, or AV receiver in service while adding wireless streaming. It's well suited to owners of vintage stereos, renters who can’t alter built-in systems, home theater hobbyists who need a compact receiver solution, and anyone who wants USB playback and device charging alongside Bluetooth streaming. If you need a transmitter for sending audio from a TV to headphones, look elsewhere — this unit is designed to receive and route audio into wired systems.
