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!
Storing Settings Within the N-Coder
The “Store to Memory” menu command permits the storage of up to 32 module parame­ter settings within the N-Coder. Settings may be read from a module and then stored in the N-Coder for ‘porting’ to other modules, or settings can be configured right in the N­Coder for downloading to modules later. Settings are stored in the N-Coder even if the N­Coder is turned off; only overwriting these settings will cause them to change.
Once parameter values hav e been selected and stored in the N-Coder's buffer (by pressing ENTER with the desired parameter values displayed), this data can be stored in the N­Coder by scrolling to the “Store to Memory” menu command:
STORETOMEMORY
* 1: ??? *
Notice the second line of the display . N-Coder permits the storage of up to 32 module pre­sets; the display above indicates that preset #1 is empty and is ready to use for storage. With the ‘Up’[d] and ‘Down’ [f] VALUE keys, you may scroll among the 32 presets. Press ENTER to store the parameter values currently residing in the N-Coder's buffer as Preset #1. The display will briefly show:
Storing to
Buffer 1
When a “Store to Memory” menu command is executed, only the parameter values cur­rently in effect (bracketed by asterisks) will be written to the N-Coder’s memory!
N-Coder automatically assigns the module name to the Preset title. If you scroll to the “Read from Memory” menu command, you can use the VALUE keys to view the various stored presets in the N-Coder. Presets will display like this:
READFROMMEMORY
1: NC-IPN
Recalling Stored N-Coder Settings for Download to Input Processing Module
Stored settings residing in the N-Coder can be easily downloaded to Input Processing Modules. 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 display current parameters for the connected module, beginning with:
CH A Level
* -80dB *
Scroll through the adjustable parameters, using the ‘Up’[d] and ‘Down’ [f] MENU keys until the following is displayed:
READ FROM MEMORY:
No
Using the ‘Up’ [d] and ‘Down’ [f] VALUE keys, you can scroll among the 32 stored presets. Once you find the desired preset for the connected module, the display will look like this:
READ FROM MEMORY:
1: NC-IPN
(Note that N-Coder will not permit module settings for one type of module to be down­loaded to a different module type). Press ENTER to move the display presets from N-
Coder memory to the N-Coder's buffer. N-Coder will briefly display:
Recalling From
Buffer 1
Parameters recalled from the N-Coder’s memory will be displayed, beginning with:
CH A Level
* -80dB *
You may then change parameter values (if desired) and download the settings to the mod­ule by following the instructions for Writing Settings to the Module.
Stand-Alone Programming with the N-Coder
Module settings can be programmed ahead of time without the N-Coder connected to a module. Saved settings can then be downloaded to the module at a later time.
Turn on the unconnected N-Coder, which will display:
Crest Audio, Inc
Revision N.NN
N-Coder will then prompt for module selection:
Select Module:
NC-IPN
Note that once a module is selected, it cannot be unselected. To select a different module, just cycle the N-Coder's power.
Scroll through the modules by using the ‘Up’and ‘Down’VALUE keys, and press ENTER to select the desired module type. (NC-IPN is used as an example here). The N-Coder will then display parameters, 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 current parameter values displayed on the second line. (Currently-selected parameter values are always bracketed by asterisks). Parameter values can be changed by using the 'Up' and 'Down' VALUE keys, pressing ENTER to select the desired parameter value.
Once parameter values have been selected and moved to the N-Coder’s buffer, follow the instructions for Storing Settings Inside the N-Coder.
Note: Once stored, settings may be changed and stored into a different buffer. However, to work with a different module type, power must be cycled.
