Putting it to use

The first remote broadcast we attempted with the Tieline Report-IT was a live sports talk show from the patio of a local restaurant. I fed a Mackie mixer into the Tieline Adapter's line input and fed the adaptor's headphone output to an external headphone amplifier.

We had a strong cell signal with four bars of 3G coverage. The App allows the bitrate to be adjusted up and down from a maximum of 64kb/s all the way down to 14.4kb/s. Since I was using 3G for this remote, I went for a middle ground of 33.6. The broadcast went flawlessly and the audio sounded quite good.

Since then, we have used the Tieline system for high school football broadcasts. We have had only one instance where we considered the audio to be unacceptable. The audio would be fine for a few minutes and then we would get stutters and dropouts. This was a football broadcast from a far-flung location where I later came to find out that the Verizon service was weak. As with all remote setups, pre-testing from each broadcast location is highly recommended.

iPhone 4 Mic Adaptor

The Tieline Mic Adapter was designed to be a standalone add-on device. It runs on two AAA batteries and provides an XLR balanced microphone input, an unbalanced line input and two headphone outputs. The headphone outputs have a mix of both send and return audio. There is also a mini-USB connector that can be used to power both the adaptor and the attached iPhone.


Having used the Tieline Report-IT for a variety of remote broadcasts over the past few months, I am pleased. With this system, we have the ability to have bi-directional high quality audio from many locations where we couldn't before. The latency seems to vary from about 0.25 second up to about one second which is certainly acceptable for real- time broadcasting. Given its relatively inexpensive cost, the Report-IT App should be a welcome addition to many stations for delivering remote broadcast options.

The Report-IT Enterprise Edition application is also available for Android devices.
