Picked up a 9855 - needs tweaking to sound better - help

[mcsoul 10+ year member]

I had an Alpine 7842, which is the same as a 7940 but with built in power.

My 7842 had a 4v output, the 9855 has a 4v output. I could no longer deal

with the 7842 not being able to play burned cd's at all. The problem is that the

sound is much different.

I think that the 9855 just has weaker "4v" outs, more like 2v and I need to set

my gains. But even at low levels the midbass is lacking and the high end, while

it is there, feels "restrained". I'll tweak my gains and see if that helps. There is a

default "factory eq" and another "parametric eq" both are flat, I think that may

help, once I sort out which to use.

Anyone have similar experience with the 9855? I think it has potential, it just will

need lots of tweaking.

About half my problem seems to be that the MX (media expander) was

turned off.

Edit:

The default HP for front and rear was 200Hz while the default sub LP was 80hz.

I was missing a huge range there.

I got all the LP HP crossover points and slopes setup. I adjusted the time correlation

for each speaker.

fr HP 80hz 24db, 26" tc-l - 40" tc-r

rear HP 63hz 6db 60" tc-l - 68" tc-r

sub LP 63hz 12db 80" tc-m

tc's are approx

I selected a preset eq setting "pop". I turned off the internal amp. I turned on MX.

I turned off the silly graphics.

Aside from the glide touch, this thing is 100% awesome now.

I had the time correction set all wrong.

Read the manual.
