NOTES • All speakers must be in their final locations before level-setting. • Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to its highest-possible frequency if you are using the T 755's Subwoofer output. Final subwoofer-level adjustment “by-ear”, using music and film sound material, is frequently useful. • Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not always calibrate to exactly the same level offset readings. You can exit “Test” mode at any time by pressing the [ Setup” menu. SPEAKER DISTANCE Your system’s speaker distance settings are a subtle but important refinement of your setup. -
