    Hi,

    I've just ordered the new Sony STR-DB1080QS reciever mainly because of it's ability to output audio to 2 sets of speakers (A+B). Apparently this reciever uses a parallel speaker-connection when running with both the A & B speakers on.

    The main room speakers is a standard 5.1 speaker-setup with 6 ohms impedance on each front speakers. (JAMO E610PDD)

    The 2nd room speakers is a pair of cheap speakers with standard 8 ohm impedance.

    Using my limited knowledge of speakers and impedance, i've calculated the total impedance as follows:

    (6 * 8) / (6 + 8) = 3,43 Ohms.

    QUESTION: will this present a problem, if I select 4 ohms on the amp ?

    Can I damage my speakers and/or reciever ? :eek:

    Any comments would be greatly appreciated !

    Thanks,
    Kenn

    If you select 4-8ohms on the rear switch, you should be fine.
    (not 8-16).
