[. . . ] From the point of view of the symbols, everything is parametric equalization; graphic equalizers are just parametric equalizers with specific default frequencies, Q (bandwidth), and type. If you want to use a graphic equalizer, you MUST use Digital Media Tools, because this is where the default graphic equalizer characteristics are set up. Programmers might want to set up sliders from the TrimBand gains to let the user modify slightly what the programmer has stored. The C2N-VEQ4 adjustments in Digital Media Tools contain five tabs: · Room Calibration ­ for analyzing the room and compensating for any unwanted effects (such as noise from an HVAC system, reflections from hard surfaces, and resonance at particular frequencies) so the listener hears what was intended when the material was recorded. Input Settings ­ for setting the input levels for analog audio sources. Using this adjustment properly lets you compensate for analog sources with different input levels to obtain a seamless transition between sources at a given volume level. Graphic EQ ­ for choosing the number of graphic equalizers, and provides access to the graphic equalizer sliders Parametric EQ ­ for making parametric equalization adjustments Communications ­ for setting up communications and adjusting the equalizer in real time. · · · · For additional details, refer to the Digital Media Tools help file. 16 · Cresnet 4-Channel Digital Volume Control: C2N-VEQ4 Operations Guide - DOC. 6135A Crestron C2N-VEQ4 Cresnet 4-Channel Digital Volume Control NOTE: Before attempting to program the equalization controls in SIMPL Windows, please study the example program. (Refer to "Example Program" on page 25. )There are some subtleties that must be carefully handled. For example, if you intend to directly set one of the TrimBandOut signals in your program, and the TrimBandOut_FB signal can be set to a different value by some other method (using DMT software or recalling presets), do not jam the TrimBandOut_FB signal back to the TrimBandOut. Oscillations might result between the directly driven value and the different feedback value. Connect the directly driven value and the TrimBandOut_FB signal to individual inputs. The same logic applies to any value that can be changed in two places. Refer to the example program. Example Program General Audio Controls ­ Slot 9, SubSlot 1 Refer to the table that follows the symbol for a list of inputs and their functional descriptions. General Audio Controls Symbol The C2N-VEQ4 symbol is defined by the assigned inputs. The diagram above shows the C2N-VEQ4 symbol in SIMPL Windows.

These controls use a logarithmic scale (0dB to ­80dB) with 0dB corresponding to 0 attenuation; anything ­80dB and below will mute the signal. The C2N-VEQ4 expects values ranging from 0d to ­800d (and lower), 0. 1dB per count, to appear at each output. (Refer to the signal description table on the next page. ) You can direct any input or combination of inputs to any output, via analog variables in the SIMPL program.
