ViaBlue NF-S1 3.5mm Stereo/RCA Y-Cable

The ViaBlue NF-S1 3.5mm Stereo/RCA Y-Cable connects a device with a 3.5 mm jack output – smartphone, laptop, tablet or portable player – to an amplifier or compact system via two RCA inputs.

This exact combination is missing in many living rooms: the amplifier has only RCA, the source device only a jack socket. Instead of a wobbly adapter, the NF-S1 handles the whole run in one continuous, cleanly terminated cable.

Why the NF-S1 Y-Cable?

A continuous cable with high-quality connectors at both ends delivers a more stable, more contact-secure connection than a jack cable plus a separate RCA adapter. Fewer transitions means fewer sources of error.

What you get

A Y-cable with a 3.5 mm stereo jack plug on one end and two RCA plugs (left/right) on the other, in lengths of 70, 100, 150 or 200 cm, in Cobra or Black.

Who is the NF-S1 Y-Cable suitable for?

For anyone who wants to connect a smartphone, laptop or portable player permanently or occasionally to an amplifier with an RCA input. Plain talk: if playback runs via Bluetooth or streaming anyway, you don't need this cable – it pays off for the wired, lossless connection.

Frequently asked questions

How do I know if I need this cable?
If your source device has only a 3.5 mm jack socket and your amplifier or system only RCA inputs, the NF-S1 Y-Cable is the right connection.

Does the cable also work with a mono jack plug?
No, the NF-S1 is designed for stereo jack outputs. A mono plug delivers the same signal on both RCA outputs instead of separate channels.

Which length and colour suits me?
Measure the actual distance between the devices and choose the next-longer standard length. Cobra matches the braided look of the other ViaBlue cables, Black stays discreet.

Can I also use the cable for a mixing desk or an active speaker?
Yes, as long as the other side has RCA inputs, the connection works the same way.

Why buy the ViaBlue NF-S1 at HD Zürisee?
