Search a way to find a replacement for a unison research unico pre remote control

Hi Dill 

Big thank for your help. 

But it is an IR remote on this link and my remote is a Rf radio frequency remote without infrared led 

All the best 

Maybe you could try the MEDION RF remote control 20017670 and use its auto-search function to see if it can control your unison Research unico.

Thank you imhiffifan

It's a good idea. I will try to buy one off this remote !

Here is the RF receipt module I've found on internet.
It's the same module on my preamplifier,

Hello everyone,

I hope you're all doing well.

I have a Unison Research Unico Pre preamplifier, which comes with an RF remote control featuring two buttons to adjust the volume (up and down).

Unfortunately, I don't have the remote control anymore.

I'm looking for a replacement solution.

The Unison Research distributor in France told me that the RF remote is no longer available for purchase.

I received partial information from someone at Unison Research, but I'm still trying to figure out how to get a remote working with my preamp.

I've found the RF receiver board inside the preamp.

According to the manufacturer, there is a button on the board that switches the receiver into rolling code mode, allowing the remote to be paired.

My main question:

Without the original remote, is it possible to pair any RF remote control?

I tried using a 433.92 MHz garage door remote, but it didn't work.

For reference, when I press the red button on the receiver, a red LED lights up.
I assume this means the receiver is in pairing mode.

Here’s a photo of the receiver module from a similar device I found online:

It's the same module in my preamp, but I couldn’t take a picture because the board is upside down and hard to access.

If anyone has an idea of how to find a compatible remote, that would be amazing!

Manufacturer’s response regarding the remote:

"Radio remote controls are rolling code and are paired by pressing the red button on the receiver board."

So, this works if you have the original remote... But since I don’t, and I can’t buy one anymore, what can I use instead?

Thanks a lot for your help!
