    I have a Sony STRDB1070 with Wharfedales on the front and Missions on the rear. However there appears to be a tiny lag on the sound coming out of the rears which leads to a slight echo effect - any ideas why this might be?

    Have you set the distance and delay times for the rears?

    Or is one of the DSP modes switched on?

    Im having a similar problem with my speakers. My rear speakers (Eltax) seem much quieter than my front speakers (Aiwa floorstanding speakers). I've tried adjusting delays, various settings etc. I think I've found a solution by changing the decibel level of the rears to +6 and having the front and centre at 0 so they sound like a match. Is this ok?


    btw Im not using a sub (yet, and it's only a small room - don't think my folks would appreciate a sub either:)) so could this be a factor? I've set my fronts to LARGE and they handle the low frequency effects.

    If it's relevant, I'm using a Marantz 4200

    Your rears should sound quiter, the sound should come mainly from the front...

    If you get a decibel meter (£25 from cornwall electronics, there is a thread about it somewhere) you should set all your rears to that, my guess is that your rears should be around 0db. unless they are a long way away from you...

    Ok thanks.

    I'll take a look around for a decibel meter then

    You need to get a decibel meter as the previous post mentioned. Then you either use use amp's internal test tone or a test disc such as Avia in the following manner (assumes amp tones used):

    Set meter to 'slow', weighting C
    Turn dial to '70'
    Play the test tone with the meter located in your listening position pointed at 45 degrees to the ceiling
    Set the front left channel to 75db (+5 on your 70 setting) using the channel modification controls for your amp.
    Repeat for all other speakers so they all read 75db at your listening position.
    Your speakers are now balanced correctly in relation to each other, enjoy the film!
