Digital Audio Processor: C2N-DAP8
Operations Guide - DOC. 8186
If you select one of the
Internal Noise
sources (
Pink
or
Dolby
), the
Source Select
drop down list is dimmed and unavailable.
If you select the
Internal Noise
Off
setting, you may instead select an external audio
source from any of the ports and select a speaker for the left channel of that audio
source to be routed to. You would use this if you wanted to calibrate your system
using an external noise source (i.e., a CD or DVD or calibration tool) or with a
specific music or movie track.
View Error Log
Clicking this button displays the error log (if one exists) as shown in the following
illustration:
Mute
Mute on the toolbar acts as a toggle. Clicking this icon immediately mutes the sound
in all channels; clicking it again turns mute off.
Mute
can also be accomplished by selecting
Tools | Mute
from the menu bar, or by
pressing
F8
. To turn Mute off, you must select
Tools | Mute
again or press
Shift F8.
The
Mute
button on the lower right of all screens is intended as a “panic” button to
prevent damage to speakers in the event of sudden large increases in sound level,
which can occur when switching from one sound source to another. Pressing this
button again does not turn mute off. Turn mute off, after the problem is resolved, as
stated above.
Using Source/Noise Steering for Calibration
Calibrating a room is a critical part of setting up a home theater. Without proper
calibration, the impact of a movie or musical soundtrack will lack what the sound
engineer had originally intended.
The Source/Noise Steering feature gives you three options to choose from to suit
your calibration needs. The definitions below give you the function of each type of
noise and its intended use for system calibration. The Source/Noise Steering feature
should be used with an SPL Meter and/or a Real Time Analyzer (RTA) for the best
possible calibration of the room.
Pink Noise:
Pink noise is sound that is comprised of a random signal, with all audio frequencies
present. It provides equal energy per octave to provide a flat response over all
frequencies. (Refer to Graph 1 after the next paragraph for visual reference.)
