I am looking for some advice regarding the amp settings for speakers in my modest surround system.
I have read a couple of articles which recommend setting all your speakers to "small" so that the lower frequency sounds are handled by the sub, allowing the rest of the speakers to use all their power to reproduce the rest of the sound more accurately.
This makes sense to me, but not, it seems, to the tech that programmed my amp: when using the setup mic, it sets all my speakers to large. I can understand this for my Xandus 5000 fronts, but my centre and surrounds are only Valdus 100s.
This begs the question: how much (blind?) faith should I put in the amp manufacturer to obtain the correct settings?
I am running an Onkyo TX-SR603, Wharfedale speakers as above and a Powercube 12+ sub connected via single channel preout.
Also I would like some advice regarding the crossover frequency settings. The the sub settings go up in 10 Hz increments from 35 to 85, while my amp has 20 Hz incs from 60 to 120, then 150. Considering the lower frequency capabilities of my fronts, should I set the crossover to 60 and match this with the sub? Or would it be better to match it with the surround speakers lower limit? This seems a bit dodgy, as I daresay some sounds in the directional range would be fed to the sub, but do I want to be sending low frequencies to those smaller surrounds?
My instincts say that I should let the amp do all the settings, apart from the surrounds and centre, which I should change to "small" so the crossover only affects these.
Any input would be greatly appreciated.
