Dolby Noise:
Dolby Noise is Dolby Laboratories version of noise intended for calibrating a room
that uses only Dolby’s Surround formats for its listening modes. Dolby specifically
created this noise to represent what a home theater frequency response should be. A
flat response is not intended when using this noise in calibration of a room.
White Noise (External Source Only):
White noise is a sound that is comprised of a random signal, with all audio
frequencies present, over time, and at various signal levels. It provides equal energy
per Hz, which will give a 3 dB per octave increase starting from the lower frequency
range (20 Hz) to the upper frequency range (20,000 Hz). (Refer to Graph 2 after the
next paragraph for a visual reference.)
CAUTION: White noise is used to calibrate electronic equipment. It provides a
signal to measure levels and drives the circuitry at all signals simultaneously. IT
SHOULD NOT BE USED TO CALIBRATE SPEAKERS IN A ROOM. It can cause
a speaker’s tweeter to burn out and cause undesired response in the room due to the
levels you would set based upon the calibration.

Communications
The Communications tab allows you to define the settings for communication with
the C2N-DAP8RC in order to download existing files and upload new ones. It is
important that you set the communication parameters first before doing any of the
other setup procedures.
