I have a JVC KD-G400 headunit that was in the Jeep when I bought it - no manual. When I push and hold the SEL button I get various options such as Clock, Dimmer, etc. There are a few that I am not sure what the function is:

AMP GAIN - Options: LOW PWR or HIGH PWR
DEMO - ON or OFF
LEVEL - ON or OFF
SCROLL - ONCE or AUTO or OFF

Any ideas?

Thanks.

jvc has a website that allows downloads of manuals for home equiptment. probably same for car audio

AMP GAIN - Options: LOW PWR or HIGH PWRthis is if your running an amp, either for highs or for bass.
DEMO - ON or OFFthis turns on/off the factory crap where it scrolls through all the different things the deck does(should be set to OFF.
LEVEL - ON or OFFi have no idea.
SCROLL - ONCE or AUTO or OFFif you have cdr/rws that you have put song and band names on the disk. it shows you what it is and who is playing.

Any ideas?

Thanks.

hope this helps.

The stereo is a few years old so it is not listed on JVC.com. I have searched the internet with no success for the manual.

Thanks mylt1, very helpful.

For the AMP GAIN, if HIGH and LOW relate to frequency it would make sense that there is a FULL option. I just added an Alpine 5 channel amp. Currently the amp is just running my dash speakers, later is will power a sub and possibly the soundbar speakers.
I guess I should have the headunit set to HIGH PWR.

Still wondering what the LEVEL setting is for.

[mylt1]

if your using the rca's for the speakers it should be set to high. if you were running a sub it would be set to low.

EDIT:

i could be wrong but, a guess on the level would be

no guessing, see nextg post

from a brief read it looks like there is a level meter which is an option on the display

Thanks ellandoh! Now all is clear. The HIGH PWR / LOW PWR actually allows user to limit the volume max 30 in LOW and 50 in HIGH. And the LEVEL function shows audio level on the display during play.

Thanks guys.
