can already years




Now you get everything

through you smartphone

It exists for so long already,
and many radio studios do it

Get listeners into the program.

It's called a telephone hybrid and has been around for over 50 years. Thanks to a telephone hybrid, a listener can be brought into the program.

The system is very old and goes back to the time when there were analog telephone lines. Later the hybrid became digital to prevent delays (echo) and there were even systems for digital telephone lines (ISDN).

But time is moving forward and nowadays we have listeners who call on your mobile phone like Facebook or whatsapp. High time to make a link between your smartphone and your mixing console.

But times are changing, now everything comes in via your mobile phone. High time to make a link between your smartphone and your mixing console!


No way

All ready for € 79,- you can do it.


How it works

A picture says more than 1000 words.

Via the 3.5mm headphone connection on your smartphone (so your smartphone must have it), you connect your mobile phone to your mixing console via our hardware. The signal from your smartphone is loud enough to go straight into your mixing console. The line signal from your mixing console (clean feed) that goes back into your mobile phone must be adapted to a signal that your smartphone can handle. The layers of tones must also be filtered out to prevent the sound from being distorted.

If you need it, we provide a connection cable with a 3.5mm jack plug to 3 RCA (RCA) male connections. You can order it for a small amount.


Uhhhh, what?

Okay, this is the hardest part. To prevent howling / echo, your mixing console needs a cleanfeed connection.

A cleanfeed is anything but itself, so you have to prevent the sound that goes back into your smartphone from getting the sound of the caller back.

Some mixing consoles have a cleanfeed output so it's simple. Another option is if your mixing console has an aux potentiometer on each channel, use it. You then open all aux potentiometers except for the channel to which your smartphone is connected.

If your mixing desk has an analog telephone fork in it that is not used, it is also an option to convert it to a line in / line output. The exit is then immediately suitable to enter the box.


The system uses a 3.5mm jack plug, your phone must have this.


Whatsapp, Messenger or just a phone call. The system works with everything you communicate with on your smartphone.


No external power is required.

The system is designed in such a way that no power connection is required.


Whichever mixer you have, as long as it has a clean feed or an aux output, it will work.

What is a clean feed?

A clean feed is everything that goes into the broadcast except itself.

My phone does not have a headphone jack

Then you have a problem and unfortunately it won't work. A 3.5mm headphone jack is required to get it working.

How do I connect it to the mixing console?

That depends on your mixing console. If you order our 3.5mm to 3 RCA connection cable, you can plug it directly into your smartphone and the box. The outputs to the mixing desk are then tulip (male), depending on your mixing console you may need an adapter.

I have an analog hybrid in my mixing console

If you no longer use it, you can use it, because a clean feed has already been provided internally. The fork must then be converted to line-in / line outputs. If you cannot do this yourself, contact our technical service.

Can I use it on a location broadcast?

Yes, you can, if you have a setup with a mixing desk on location, you actually have the same as in a studio.
