About the N-Coder
The hand-held N-Coder is used to configure all Input Processing “NC-” Modules except for DSP modules. The N-Coder allows you to change parameters affecting the amplifer's level, eq settings, crossover point, etc. Once set, the parameters are stored in non-volatile memory so that the amp will always power up the same way -- without battery backup. Processing parameters can also be created and stored ahead of time in the N-Coder with­out any modules attached, then downloaded to the modules later.
Powering the N-Coder
The N-Coder can be powered from a common 9VDC battery or the supplied 12VDC wall adapter. To install a battery in the N-Coder, remove the battery cover on the back of the N-Coder, connect the battery to the snap-on terminal, insert the battery into the cavity, and replace the cover. To connect the 12VDC wall adapter, insert the adapter cable plug into the N-Coder’s 12VDC In port, and plug the wall adapter into a 120V 60Hz AC mains out­let. Whether powered by battery or wall adapter, the N-Coder must then be switched on. (See diagram below). Note:
Notes: The N-Coder does not have an Auto-of f featur e . As suc h you must r emember to turn off the unit after use. The unit's Serial Number is also located inside the battery compart­ment. When a 9VDC battery has been installed in the N-Coder AND the wall adapter is connected, the N-Coder will use the wall adapter as its primary power source. The N-Coder must always be self-powered – a con­nected Input Processing Module does not supply power to the N-Coder.

position. If N-Coder is being used, jumper position must be in the “NCODE” position.
Connecting the N-Coder to the Input Processing Module
The N-Coder is connected to Input Processing Modules using an RJ-14 cord (supplied). One end of the cord plugs into the N-Coder’s RJ-14 port (located on the top of the N­Coder), and the other end plugs into the Input Processing Module’s Data Port. (See dia­gram below).
NOTE: the supplied RJ-14 cord (Crest part number
82510045) uses a ‘six con­ductor’cable. It is NOT the same as a common tele­phone cord, which uses a ‘four-conductor’ cable.

Programming with N-Coder connected to module
Connect the N-Coder to the Input Processing Module using the supplied RJ-14 cable. Once turned on, the N-Coder will display:
Crest Audio, Inc
Revision N.NN
N-Coder will automatically identify the connected module, read its current settings, and briefly display the module ID (NC-IPN is used as an example here):
Reading Module:
NC-IPN
Then N-Coder will then display current parameters for the module, beginning with:
CH A Level
* -80dB *
To scroll through the adjustable parameters, use the ‘Up’ [d] and ‘Down’ [f] MENU keys. Parameter titles will be shown on the top line, with the parameter values displayed on the second line. (Parameter values that are currently in effect are always bracketed by asterisks). Parameter values can be changed by using the ‘Up’and ‘Down’VALUE keys.
Programming with N-Coder connected to module (continued)
Note: Changes to parameter values can be ‘auditioned’if you are passing signal through the amplifier to your loudspeakers/drivers. However, these audible changes will not be permanent unless you:
A: Save the settings directly to the module; or B: Save the settings to the N-Coder for later download.
The following NC-IPN (Basic Input module) parameters are common to all NC Input Processing modules:
Parameter Selectable Values
CH A Level 0dB to -80dB CH B Level 0dB to -80dB Phase A+ B+ / A- B- / A- B+ / A+ B-
WRITETOMODULE Yes / No STORETOMEMORY Yes / No READFROMMEMORY Yes / No
Channel A and B levels are attenuated in whole number dB steps. Four different channel phase settings are available.
Once you have adjusted a parameter to the desired value, press ENTER. This will cause the displayed parameter value to be saved into the N-Coder’s buffer. This will be indi­cated by the asterisks that appear to either side of the displayed (“current”) value.
Writing Settings to the Module
Parameter adjustments can be saved to the non-volatile module memory by scrolling to the “Write To Module” menu command, selecting the value “Yes”, and pressing ENTER:
WRITE TO MODULE
* Yes *
Remember that when you execute a “Write to Module” menu command, only those parameter values that are bracketed by asterisks will be written to the module!
