Durable, high-quality mic that picks up an amazing range of audio, including conversation or radio in the pits and engine noise on the track. System software includes AGC (automatic gain control), which adjusts audio levels automatically.

The mic loom assembly is delivered with a standard Race-Keeper microphone on the left channel and a standard female 3.5mm mono jack input on the right channel for capturing intercom audio or radio chatter to and from the pit crew or race control.

Race-Keeper Comparo plays both left (mic) and right (radio input) audio channels; you can listen to both channel at the same time or use the stereo balance control on your PC to fade out the left or right channel as required.

If you're recording in an open cockpit (e.g., Single seater racecar or road car with windows down), consider adding a Dead Kitten wind cover to reduce irritating high frequency wind interference.

Note about Audio Balance
Audio Balance controls are sometimes hard to find on laptops!
Here's how to get to the balance control on a Windows 7 laptop.
1) Open the Volume control panel by clicking on the speaker icon bottom right of you screen http://i53.tinypic.com/b6a7ir.png
2) In the Volume control panel, Click on the Speaker
3) Speaker Properties window opens: http://i54.tinypic.com/9fwi9t.png
4) Click on Levels tab, then click on the Balance button. There you see the left right balance sliders: http://i56.tinypic.com/2iazk7q.png
5) Right channel is the in-car mic, Left channel is the radio input. Slide the Right channel down to reduce the in-car noise.

Dolby Surround sound features can sometimes blur the separation between Left and Right audio channels. Turn this Dolby setting off when you need to listen to just left or just right channel audio. In Windows 7, the Dolby settings are here: http://i54.tinypic.com/10zw952.png

If you can’t find the audio balance settings or the Dolby sound settings on your laptop or PC, plug in your headphones and listen to left right separation on the Race-Keeper outing that way - take out the in-car mic side ear piece to hear just the intercom.
