Thread: Noob. Need help with tuning.

    Re: Noob. Need help with tuning.

    And Btw my HU, alpine CDA-117E, has 24 bit burr brown DAC. I bought this only because of that and I "thought" with a powerful DAC, I won't need a sound processor.
    Am I wrong in thinking that??

    I did some research on my own and did some tuning using a digital multimeter. And it has started sounding really good.

    As far as the music I listen to is concerned. It's a mixed bag, ranging from rock (tool, zepplin, Def leppard) to full on party/trance (Edward maya, swedish house, etc).

    Now some tuning details:
    HU
    - I have the HPF turned off on the HU.
    - subwoofer level set @ 8/15
    - fader ranges from -15 - +15. I ve set it @ +3. (front bias).
    - haven't touched the time correction.

    Amp F30
    - gains set using multimeter @ 13.8V for all channels.
    - HPF set @ 90Hz
    - bass boost to minimum.

    Amp T300
    - gains set at 19.5V using multimeter
    - LPF set at 100Hz
    - phase 0.

    These are pretty much all things I adjusted. And used a 60Hz sound signal to tune.

    On some Alpines 15/15 was a 'Normal' bias for the subwoofer [ even with other speakers ].

    Try flipping phase from zero to 180 [ listen to song, flip phase, listen again to same song ]

    The DAC turns the 1's and 0's into an analog signal, it doesn't control the tuning options, afaik. As Hifi stated, get your time alignment set as per the manual (use the distance to the front woofers, not the tweeters), and see if you like it. If you are happy with that, enjoy it and leave it alone.

    Also when you are setting the delay I would set the EQ to flat (just something that I do) and then once you get the sound centered to your liking start on the EQ. I would also recommend using the high pass filters on the front comps and rear coaxials to remove some of the low end that would be going to the sub anyways but that's up to you.
