Stream from your phone to your stereo, the Gold Series way

The RA-Twin II Bluetooth adapter plus our shielded Gold Series 3.5 mm to dual RCA cable: the cleanest way to add Bluetooth to a vintage receiver or amplifier, for less than buying the two separately.

What’s included Set up Why Gold Series Videos FAQ Manual

The short answer

The RX bundle is the RA-Twin II Bluetooth receiver and transmitter plus our Gold Series 3.5 mm to dual RCA cable. Plug the cable into any line-level input on your stereo (AUX, tape, tuner or CD), set the RA-Twin II to RX and stream from your phone, tablet or laptop. The Gold Series cable’s heavier shielding also stops the noise a basic cable can pick up after the RA-Twin II switches itself off.

What’s included

RA-Twin II Bluetooth adapter

Our best-selling, pocket-sized Bluetooth 5.4 receiver and transmitter: up to 10 m of range, up to 10 hours per charge over USB-C, and a microSD player built in. About the RA-Twin II

Gold Series 3.5 mm to dual RCA cable

Our shielded, gold-plated cable with an integrated degaussing ring and a flexible gold mesh jacket: a serious step up from the basic starter cable. About the cable

Set up in three steps

Connect

With your amplifier or receiver turned off, plug the Gold Series cable’s 3.5 mm end into the RA-Twin II and its RCA ends into a line-level input: AUX, tape, tuner, CD or video. Don’t use the phono input; it’s designed for a turntable’s much smaller signal.
Pair

Hold the RA-Twin II’s Power button to switch it on and slide the switch to RX. Turn on Bluetooth on your phone, search for “RA-Twin II” and pair. The RX light stays on once connected.
Play

Turn on the amp, select the input you used, and start the music on your phone. Next time, it reconnects to your phone automatically.

Why the Gold Series cable

Cleaner signal

Heavier shielding and a degaussing ring keep hum, hiss and interference out of the signal between the RA-Twin II and your amp.

No noise after streaming stops

The RA-Twin II switches itself off after 10 minutes without a connection. With a basic cable, an amp left on that input can pick up noise through the cable; the Gold Series shielding stops it.

Built to last, costs less bundled

Gold-plated connectors and a flexible mesh jacket for years of plugging and unplugging, for less than buying the adapter and cable separately.

Radique Audio RA-USB charger plugged into the AC outlet on the back panel of a vintage receiver

Keep it charged at your stereo: the RA-USB

A huge range of vintage receivers and amplifiers have AC outlets on the back panel. Plug our RA-USB multi-port charger into one and your RA-Twin II stays charged right where it lives, with ports to spare for your phone.

RX bundle questions

Will this work with my vintage receiver or amplifier?

Yes. Any stereo with an RCA line-level input works: AUX, tape, tuner, CD or video. Avoid the phono input, which is designed for a turntable’s much smaller signal.

Can I use it with powered speakers?

Yes, if they have RCA inputs. Plug the RCA ends into the speakers’ input and stream from your phone.

How is this different from the RA-Twin II on its own?

The RA-Twin II on its own comes with a basic cable. This bundle adds our shielded Gold Series 3.5 mm to dual RCA cable, for a cleaner signal and no noise after the RA-Twin II switches itself off, at a lower price than buying the two separately.

Why does my amp make noise after I stop streaming with a basic cable?

After 10 minutes without a connection the RA-Twin II switches itself off, and if the amp is still on and set to that input, a basic cable can act like an antenna. The Gold Series cable’s heavier shielding stops it. With any cable, you can also turn the amp off or switch it to another source when you’re done.

Is there a manual?

Yes: the full RA-Twin II manual is online in English and French, each with a printable PDF.

Do you ship to the United States?

Yes. On Radique Audio products we add the US import duties and fees at checkout and prepay them for you, so there’s nothing to pay at delivery.

What warranty does it have?

The RA-Twin II carries a 1-year Radique Audio warranty, with support from our team in Ottawa. See the warranty FAQ.

Bluetooth for your stereo, done right
