    Help..........i have the sony strdb940 and in the great traddittion of user manuals the following is not explained.

    1)you can set the individual mhz for bass,treble and mid for fronts,centre and rears......what should each be set to ???

    2)when setting up subwoofer you set fronts,centre and rears to small so bass is re-directed to sub..........it then allows you to set each speaker fronts centre and rear with either 60,90,120,150 or 180 hz
    what do you set these to ????

    is there a degree avilable to study to set these babies up.........or do manufacturers assume we are all BBC soung engineers

    can any one help with above layman replys would be great

    Paul

    not entirely sure but i'd imagine there's
    a setting on your sub to tell you at
    what frequency it comes in. i think i
    read that you should set this as high
    as possible and then set the freqency
    for your speakers on your amp to this value.
    it's worth a go i suppose!!!

    btw what's the address of the other site
    you were talking about?

    I'd go for 80 Hz. That's the THX crossover (I think), and it works fine for my amp - which isn't a THX-er.

    I have an earlier model, the 925, but went through the same problems when playing with the amp. I have left all these settinhs at their factory defaults after much experimentation, as I don't think you can achieve anything really beneficial without serious measuring equipment to study the waveforms in your room. If you did that, then you'd probably find the adjustments on the amp too coarse anyway, so it's best to leave alone and write it off as a gimmick.

    In order to get the best sound from your system invest in a copy of Avia or Video Essentials from the US, and an SPL meter from Tandy. Use the test signals on the disc to precisely balance your 5.1 system and your picture settings and you will be amazed at the results.

    If there is anything else drop a message and I'd be glad to help.

    Cheers Carl..........the only problem with all these frequency settings is that when you set up etc and start messing around there is no default re-set or any details in the manual ???? so you don"t know what they were set at in the first place
    i think the only thing to do is call sony for advice......

    I will have a look at the EQ settings on my amp tomorrow and then you should be able to get back to your baseline.

    As someone mentioned above, those are the crossover frequencies- the frequency at which the 'sound' will 'crossover' from speaker to sub.

    It all depends on what speakers you have.
    A good place to start is by using the crossover value above the frequency your main speakers are rated to.-

    Eg. Mains rated down to 40Hz, so the 60Hz setting would be a good choice.

    In a satellite/sub setup your mains could be rated down to 120Hz, so try the 150Hz setting, however, the higher you crossover the more bass becomes directional. This may be a problem especially if your sub is not in your front soundstage. In this case 120Hz (or lower) may give better results, or move equipment.
    These are just a couple of examples.

    As always- whatever sounds best to you, however the idea is to have no holes in the frequency spectrum, 20Hz-20KHz.

    Hope this clears things up a bit.

    Cheers.

    thanks for your help However this is not what i am looking for, i know how to set the sub crossover on the sony str940........the thing i am looking for is that you can set the individul frequency settings for front bass,mid,treble....centre bass,mid,treble and rears bass,mid,treble............but what do you set each frequency to ? and why ?

    Sorry Paul.

    It does sound like adjustable crossover frequency settings in your first post.

    Reading your last post it now sounds like some sort of equaliser settings for each channel.
    Maybe someone who is familiar with this amp can clear things up.

    Cheers
