  • Page 22: Speaker Configuration

    OPERATION USING THE T 775 – SETUP MENU SPEAKER CONFIGURATION Every surround-sound system requires “bass-management” to direct low-frequency content from any or all channels to the speakers best able to reproduce it. For this function to operate correctly, it is important that you correctly identify your speakers’ capabilities. We use the terms “Small” and “Large” (and “Off”) but note that physical size may be irrelevant.

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 key, bringing you back to ‘Speaker Setup’ menu. You can also press the ‘TEST’...
