In this post we are going in-depth on the spf.io microphone setup. Each venue is a little different so you may have a slightly different setup. This post is just focused on the essentials here. If you aren’t sure how to set up the laptop and the audio connection for spf.io, follow along with us!

  1. Reliable internet (wired connection is HIGHLY recommended)
  2. Laptop with Google Chrome
  3. Audio connection with soundboard

 

The spf.io microphone setup

Plug the microphone audio to the microphone input of your computer. Work with your venue A/V tech person to get the microphone output from the soundboard into your laptop. There are two potential setups to make this work.

Frugal Option: From the soundboard, get audio out with a 3.5mm male-to-male TRRS cable or 3.5mm to RCA cable. Plug the cable into the soundboard and then plug the other end of the cable into the laptop microphone input.*

* Find your laptop’s microphone jack. To check if your laptop has a separate microphone jack, first locate your headphone jack. If you see another similar input with a microphone icon next to it, that indicates you have a dedicated microphone jack.

If you have only one input, that means you do not have a dedicated microphone jack and you will need a USB converter (affiliate link).

On the USB converter, you will see two inputs: one headphone and one microphone (typically pink).

Plug in the USB converter to the laptop and allow a few moments for the device driver to install itself.

 

Premium Option: Alternatively, use a USB audio interface (affiliate link) device to accept audio out from the soundboard with an XLR cable. The device will plug in directly to the computer via the USB port.

Laptop physical setup

There are two simple but important parts to setting up the laptop in the venue. First, get connected to the internet–we highly recommend a wired ethernet connection because it is the most reliable. If your computer does not have an ethernet input, you will need a USB ethernet adapter

If you need to rely on wifi, have a backup plan in place. One potential backup solution is to use a cellphone as a mobile hotspot.

And second, don’t forget to plug into a power outlet! If your event goes beyond an hour, this will ensure you can keep going for the entire event.

Next step is to set up the microphone audio with spf.io.

 

Selecting the right microphone input in spf.io

First, open the session’s operator view in spf.io. If it is your first time entering the operator view, it will ask you to allow access to the microphone. Click “Allow”.

Ensure the operator view is opened in the same channel as the language that will be spoken the majority of the time. So for example, if the event is conducted in English, choose the English channel.

Now turn on the microphone by clicking on the microphone icon.

Next, we need to confirm that the correct microphone input is selected. In the right-hand side of the browser’s URL bar, click on the Camera icon and note the microphone input selected. NOTE: You do NOT want it to select the Built-in Microphone! If that is the current input, click on the dropdown and select the correct input as the microphone input.

Next, open the audio visualizer to see the sound as it is coming through the microphone. Look for this icon:

Speak into the microphone to test and confirm the setup is working as expected. If the captioner is enabled, you should see it generating the text it is hearing.

 

Disable the captioner once your testing is complete until your event begins.

 

Common Setup Mistakes

We see a few mistakes that can cause issues in the microphone setup. If you’re experiencing some problems, try going through the steps outlined below.

  1. The wrong microphone is selected – be sure to select the correct input as the Microphone input. It should not be using the built-in microphone.
  2. The wrong language is selected – be sure the interpreter view is set to the correct language.
  3. Microphone audio is too loud or too soft – use the audio visualizer to ensure the audio coming through isn’t causing clipping, or isn’t so soft that the captioner is unable to pick up anything. Applying compression to the audio may help (work with the A/V tech person on this).
  4. Poor internet – as we have mentioned, it is extremely important to have reliable internet. The best way to guarantee this is to have a wired ethernet connection with your laptop. If that isn’t possible, then we recommend tethering with a mobile hotspot that has a strong connection within the venue.
  5. The incorrect locale is selected – for example, if the speaker is speaking English but their accent is British rather than American, selecting “United Kingdom” would be the better locale than “United States”.

How do I deal with culture clash?

Although the apostles and elders protected the gospel from being collapsed into a false one of cultural conformance, they still faced a very practical issue.
