Speaker Distance; Adjusting The Volume - NAD T755 Owner's Manual

To produce the same SPL meter reading (or subjective loudness), use the remote's [
adjust each speaker.
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. Informing
the T 755 of the loudspeaker-to-listener dimensions of each speaker automatically imposes the correct
delays, optimizing imaging, intelligibility and surround-sound ambience. Enter your dimensions with
precision within about 1 foot (30 cm).
SETTING SPEAKER DISTANCE
While at "Speaker Distance" menu, use the [
Surround Right, Back, Surround Left and Subwoofer to the distance measuring from your principal
listening position to the front surface of their corresponding loudspeakers. Distance can be set up to
30 feet or 9.1 meters.
Distance can be displayed as feet or meters selectable at the "Unit of Measure" item.

ADJUSTING THE VOLUME

In addition to the Volume knob, use the HTR 3's [VOL
raising or lowering the channels altogether. A momentary keypress will change the master volume by
1 dB increments. If you hold down [VOL
released.
Since recordings vary considerably in overall average level, there is no imperative to listen at any
particular master-volume setting. A setting of -20 may sound "as loud" from one CD or DVD as -10 does
from another.
The T 755 will power-up from Standby mode at whatever master volume setting was last used;
however, if the prior setting was greater than –20 dB, the T 755 will power up at –20 dB. This prevents
inadvertently beginning a session at excessive volume.
MUTING THE SOUND
Use the HTR 3's "Mute" key to silence all channels completely. Muting is always available regardless of
the source or listening mode selections.
NOTES
• Changing input or listening-mode selections does not release muting.
• Adjusting the master-volume upward via the HTR 3 or the front-panel knob automatically releases
the mute function.
