program for those individuals who wish to do the system setup and room balancing
functions via a touchpanel.
NOTE: Crestron recommends setting the analog parameters of the C2N-DAP8
in only one way—either through the DAT software or through the SIMPL
Windows program. However, if you must allow both, please read and
understand this warning.
There are some subtleties that must be handled in a way
that is a bit different from what you may be familiar with when using similar
devices. For example, if you intend to directly set the C2N-DAP8 <
Volume>
analog
input in your program, keep in mind that the <
Volume_FB
> signal can be set to a
different value through some other method (e.g., using the DAT software). In other
words, the C2N-DAP8 actually stores these parameters, as opposed to a CNXVTC-3
or ST-VC, where the value is stored solely in the control system. If you were to just
use an Analog RAMP symbol and send the output of the RAMP to the <
Volume
>
input and jam it with the <
Volume_FB>
output of the C2N-DAP8, Oscillations
might result between the RAMP and the actual <
Volume_FB
> value from the C2N-
DAP8.
This could cause damaging volume levels to be sent to your speakers.
Instead, use the "Analog Increment with Optional Feedback" (AINC) symbol.
Connect the <
aout
> output of the AINC to the <
Volume
> input of the C2N-DAP8,
then connect the <
Volume_FB
> output of the C2N-DAP8 to the <
[FbckSignal]
>
input of the AINC. This way, the program will always be updated with the true value
of the C2N-DAP8. The same applies to any analog value that can be changed from
two places (EQ, Trim, etc.).
Test Equipment
No matter which method is used to set up the surround sound system in the listening
area, the following items are required:
•
SPL (Sound Pressure Level) Meter. Used to measure sound in decibels
(dB). This is used to calibrate the speakers so each produces the same sound
level at a given volume setting.
•
Tape Measure. Used to measure distance from speakers to main listening
position.
The following equipment is recommended to optimize the performance of the C2N-
DAP8 relative to the listening area, speaker arrangement, and the user’s preferences:
•
Audio Spectrum Analyzer. Used to “see” a speaker’s frequency response in
a room. This is used with equalizers to adjust for a proper room response.

information and extensive instructions, including video test patterns and audio test
signals, for setting up a home theater environment.
