No magic. Tune with appropriate methodology as suggested.
"One additional control is available, the phase control. Now some of you have probably twiddled this control back and forth, heard very little if any difference and so left it at the center detent. That's one technique. Here's a better way. Select a mono musical source, preferably a musical piece originally recorded monophonically and properly mastered on CD or DVD. One of my favorite pieces for this is the reissue of John Coltrane's "Soultrane" on DCC Classics, especially the track "Russian Lullaby."
Now, playing the soundtrack through the Dolby Pro-Logic settings, you should get output only from the center speaker and the subwoofer. Listen carefully to the interplay between the bass guitar and bass drum or piano left cable.jpg hand. The impact of the drum is much higher in frequency than the deep, resounding skin sound. What you want to accomplish is to have the initial impact of Arthur Taylor's drum kit precede the deeper drum skin sound and the note from the bass guitar (by the way, it doesn't hurt if that note is lovingly teased from the instrument by Paul Chambers!). This establishes the correct phase relationship between your center speaker (and by extension your left and right main speakers) and the powered subwoofer." |
