Alpine headunit set-up question

**y2blade** · Tuesday 29th July 2008, 13:21

as you will know i fitted this headunit last week http://www.vpcuk.org/forums/showthread.php?t=16175 and it's all fine and dandy, working and sounding great

my query is thus, I was through the settings and came across "bandwidth"- 1 to 4??????? what does that mean and what setting should it be on!?!?

yeah yeah prob a stupid question but "if you dont ask you wont learn"

thankyou in advance

i cant actually see a bandwidth mentioned in the manual below, but there are a couple of width, or bandwidth options, without know which menu your in, i cant comment.

have a root for yourself

thanks. its the bandwidth that is mentioned on the bass setting page it says bandwidth is adjustable with 4 settings 1 is narrow 4 is widest . . . any clearer? ive left it on number 2 as thats what it was on, just wanted to understand what it ment.

the above reply was from memory as my phone wont open pdfs but i do have the manual for it at home . thankyou anyway.

right, that's effectively a parametric EQ setting, and its altering the "Q" setting.

in english, the bass boost is at a set frequency (60/80/100/120hz)
your changing how wide that boost is (ie are you boosting a very narrow band of bass, or a wider band)

the narrow setting (4) might only effect 110-130hz for the 120hz setting, at its widest (1) it might be doing 80-160hz

have a play and see what you like the best

no wurries, like i say, check out www.talkaudio.co.uk, or www.caraudiodirect.co.uk for more info.

miamivice is the font of all knowledge on alpine stuff so its worth asking him if you need to know anything in detail
