I have the Kenwood KDC-x859 and the features on it is unbelieveable! Unfortunately, I have NO IDEA how to use more of them. There is this HPF thing and I have no idea what it does. What is it?
Also, it allows user to adjust the center frequency of bass (60/70/80/100Hz) midrange (500Hz/1kHz/2khz) and treble (10/12.5/15/17.5kHz). The bass "Q" is adjustable (1.0/1.25/1.50/2) and so is midrange "Q" (1.0/2.0).
What the hell does it all mean????? [IMG]i/expressions/face-icon-small-confused.gif[/IMG]
I am running Infinity Components up front, hooked up to a MTX amp. In the rear is just my OEMs. I like having soild sound from the front, and just fills in the back. What do I do with the setting? Could someone explain it all to me?
THANKS!

Ok, I have a Kenwood KDC-x559, so mine has a lot of similiar features. I also have an MTX amp for my front speakers. Going by the advice given to me set all of your Qs at the lowest settings.
For the frequecy centers, that is highly subjective. You can experiment with the pre-sets, and change to your liking. You can also make your own random one. I think I have my highs at 12.5 and my mid at 1khz. I have them both at +3. I have my Bass at 60 hrtz, but I keep it at 0 so it doesn't matter. I also keep my NF output to -5 or - 7 on a normal driving day, because I couldn't handle that much bass all of the time!![IMG]i/expressions/face-icon-small-tongue.gif[/IMG] Experiment and see what you like [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

With your setup, i would set the HPF for the front between 40-80, and the rear I would maybe let it go a lil lower or set the LPF to a middle to high setting. I have never had a set-up like that to set, but I am thinking about what I would try first. I have to think about this, because I gotta leave work now [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

The idea is to tailor how the equalizer system works.

Heres some example numbers for ease of discussion ....... some numbers may not be realistic .....

Low grade systems just have bass and treble adjustments.
Here you can boost
- Low: 100hz +/- 10db
- Highs: 10,000hz +/- 10db

Better ones have low, mid, and high.
Here you can boost
- Low: 100hz +/- 10db
- Mids: 1,000hz +/- 10db
- Highs: 10,000hz +/- 10db

Now days they give you low, mid, and high ... combined with freq and Q control on each.
Here you can boost
- Low: choose 60 or 70 or 80 or 100hz___+/- 10db____with a Q of 1, 1.25, 1.5, and 2
- Mids: choose 500hz or 1,000 or 2kHz___+/- 10db____with a Q of 1, 1.25, 1.5, and 2
- Highs: choose 10kHz or 12 or 15kHz____+/- 10db____with a Q of 1, 1.25, 1.5, and 2

Q designates how steep of a boost you have.
I believe the smaller the Q, the steeper the slope.
Q of 2.0 might be like a 6db crossover where a Q of 1.0 might be like a 18db crossover.

For example:
Freq: 80hz
Q: 2
Boost setting: +6
Result boost: (+2 @ 60hz) (+4 @ 70hz) (+6 @ 80hz) (+4 @ 90hz) (+2 @ 100hz)

For example:
Freq: 80hz
Q: 1
Boost setting: +6
Result boost: (+1 @ 70hz) (+6 @ 80hz) (+1 @ 90hz)

So where this is handy .... is if your sub amp is crossed over at 75hz ...... then there is no point in boosting at 100hz on the deck to get more bass. You should set it at 60hz and then boost the bass. Then it will work much better obviously.

You could also use it to tame freq humps at specific frequencies etc .........

rrrrriiiiiiggggggghhhhhttttt..... there are times i wish the manuals will explain how to USE the features, and its effect, instead of just tell us how to change them.

If you look on Kenwood's website they also have an e-mail where you can asked them about features that they don't explain...like Woofer type A, B, C, and D. [IMG]i/expressions/face-icon-small-wink.gif[/IMG]

Joe, I think it may be the other way around but I need to check. If I remeber correctly there is a lil graph that shows when you change the Q and the higher Q has the steeper slope...and the lower Q is more flat. Regardless, if you have a Kenwood with Q adjustments the graph will tell you what you are doing, as long as you know what Q is.

Ya I can't remember exactly ..... I think my Pioneer just has N and W (narrow and wide).

so what does the System Q do anyway??? I've changed some of the settings, but never heard any difference.
also, what is HPF and what does it do?

I've emailed kenwood, but they still have not gotten back to me yet.

Q adjusts how sharply the frequency is adjusted on your deck for bass, mid, or treble.

Look at the examples I made to see how it affects the frequency range. Think of it as boosting the freq level from that spot quickly or gradually.

If you set you amp sub crossover at 50hz, and play with the Q around 80hz, you probably won't notice a thing. That might be your problem.



The HPF is a High Pass Filter ... LPF is Low Pass Filter. This IS NOT correlated w/ the Q settings.
These adjusts how the crossover works. Lets say yours are both set to 80hz.

Turning on a HPF will allow from 80hz and up to be played.
Turning on a LPF will allow from 80hz and down to be played.

If your HPF is turned on the front and rear RCAs won't get bass below the 80hz.

Usually HPF affects front RCAs, rear RCAs, front and rear deck power.
Usually LPF affects only the sub out (non-fading) RCAs.

so what are the settings usually left at?
Currently, I have my bass turned up all the way (+8), and treble left at normal, and Midrange is at +1.
So how should i adjust the frequencies?
The choices are as follows:
bass (60/70/80/100Hz)
midrange (500Hz/1kHz/2khz)
treble (10/12.5/15/17.5kHz)

I have e-mailed kenwood about a week ago and have not heard anything either. I asked many questions [IMG]i/expressions/face-icon-small-tongue.gif[/IMG] including what does the Woofer A, B,C, and D settings.

I just called them about that Woofer setting thing, and I got some dude who was in training and was hella nervous...he told me to hold and would check...when he got back this is what he said "that feature is basicaly useless. You are better of f just going with the setting you have it at right now". i thoght that was Hilarious!!!!!!!

ok, one last quick question.
Is higher frequencies for a higher pitch or a lower pitch? Like 100mHz compared to 80 mHz. Which one will produce a higher pitch? If I want a solid strong bass, do I set the speachers to accept a higher or lower frequency?

 
Rep Power: 346

Bass=Low frequecies
High=high frequencies (tweeters)

You should set your bass from 85hrtz or below depending on you musical preference.
