Can anyone tell me why the sound is distorted, Is it because the Chasecam is powered off the vehicle 12v system and there is no suppressor fitted or is the engine too loud and a setting requires altering?

Cheers

Hi,
You'll find the answer here :

....
AUDIO INPUT CONTROLS
There are three options under AUDIO INPUT CONTROLS. You can set the AUDIO GAIN
LEVEL; select INT/ETX MICROPHONE LEVEL; and SOURCE MIXING.
When the AUDIO GAIN LEVEL screen is up, the selection of the input audio level can be made.
Pressing the UP or DOWN keys moves the highlighted selection between the choices. Pressing
the SELECT key makes the selection and returns to the CONTROLS menu. Pressing MENU
returns to the Recording Standby Mode condition without changing the audio input level, and
pressing ESCAPE returns to the CONTROLS menu without changing the audio input level.
There are four preset INPUT LEVEL selections, which are usually best for the kind of input the
selection describes:

EXT LINE IN (for using the external audio line-in connector)

EXT MIC CLOSE UP (for two electret microphones of sensitivity similar to that of the onboard
microphone, plugged into the external microphone jack)

INT MIC CLOSE UP (for a speaking voice nearby the PDR100's microphone)

INT MIC WIDE AREA (for the PDR on-board microphone to pick up room or other area
sounds).
There is also a selection labeled CUSTOM. This allows the user a choice of input level other than
the presets. A bar graph shows the relative amplification, which is selected by using the LEFT
and RIGHT keys. This is for left and right channels. Note the small arrow which shows you which
channel is being changed. Use the up and down cursor to toggle between the channels. When
one of the presets is highlighted, the bar graph corresponds to the level for the preset. For a loud
racing car (for an example), select OTHER and slide the bar graph to the left. A good place to
start may be two clicks off full left.
INT/EXT MICROPHONE LEVEL. Set this to HIGH or LOW depending on the level of sound.
Suggestion is to set it to LOW for use inside of a racecar.

Hope it's help you

Michel,

Thanks for the help.

We've also made an update on our latest firmware that extends the low end of the spectrum so you can turn the gain down further for extremely noisy situations.

Thanks!

So is it more likely to be a noise problem rather than interference from the charge circuit on the 2 Suzuki gsxr engines in the car?

I tried to alter the sound settings before I raced but couldn't seem to get the settings to move.

Thanks Andy

Ive already dowloaded the latest firmware also.

Cheers Andy

I guess it's possible, but I'd expect to see video interference as well if that were the case.

The mic is inside the recorder, so if the recorder is mounted in a spot that's blasted by noise, that might be an issue. My guess is some combination of turning down the gain and possibly moving the recorder position will solve your problem.

Thanks.

Ok i'm gonna try it again this weekend, I was actually using an external mic but now I've read the instruction book a bit more I suspect the sound level was on the wrong setting.

I've set it to custom now and pulled the volume bar down to the left (on 1 bar).

Cheers again

Andy,

I'd also suggest at least trying it without the external mic. In general, unless you have a shielded mic, external mics are much more prone to collecting wind noise. While that doesn't sound like the core of your issue, it could be contributing.

Thanks.
