How to record or broadcast with phone calls


We are receiving many calls from clients who want to make their podcasts and its streamings from home, with the possibility of making mobile calls. We explain the simplest way to do it.

The first thing is to make an inventory of the needs we have. Above all, the number of microphones, and if we are going to connect an instrument or external sound source. We are going to give you the example taking into account that we are going to use two microphones, so that as an announcer we can have a guest in the room. studyeach one with his microphone.

You don’t need equipment like the one in the photo. In fact, the table that we are going to use is one of the cheap:


What is important is that the mixer includes USB interface, to be able to connect to the computer without having to use the integrated card on the motherboard, which is usually quite poor and does not have microphone preamps. It must also have subgroup or, failing that, send effects (this is usually cheaper). In our example, we are going to opt for shipping.

Now, we are going to need to connect our smartphone to the mixer, and for that we are going to use this cable:

minijack cable to two female minijack

As you will see, it has a male minijack with four contacts (three grates), which we will connect to the phone’s headphone jack. The other two connectors, two female minijacks, are one for a microphone and the other for a headphone.

And this is where we are going to do the trick. We are going to connect that microphone connector (the red one in the photo) to the shipment of our table:

FX Send Q802USB

So we are going to need a jack cable fat (6’3) to minijack (3’25), like this one for example:


Roland minijack to jack cable

Well, we now have the sending connected to the mobile’s audio input. So that? Well, in this way, we are only going to send to the smartphone (so that the person we call can hear us) the channel we want, raising the “FX” potentiometer (the red one) of that channel. If we want to send channel 1 and 2 (those with the microphones), we will raise the pot FX of those channels, so that the audio from our two microphones reaches our interlocutor.

Q802USB FX Potentiometer

Well, the audio from our microphones now reaches the person on the other end of the calls. Now our listeners will also have to listen to what this person says. To do this, we are going to connect the green connector of our double minijack to channel “3/4” of the mixer. To do this, we need a stereo minijack to 2 mono jacks:


Stereo minijack to 2 mono jacks

Of course, we will have to raise the “LEVEL” potentiometer of channel 3/4 so that the interlocutor can be heard.

With this, we already have the person we are talking to on our mobile phone on our mixing console, so we will be sending it via our USB cable to the computer to the recording or streaming program that we use.

Of course, you can choose other mixer in this section of our store.

A very cheap and relatively simple way to make our program more interesting with the possibility of remote guests.
