Test program
Running the test program
The Nord Stage test program is stored both in Flash and in the BootPROM position U6.
Test program version is shown on the Stage display when the test program is initiated.
In order to trace a hardware error easier, each Nord synthesizer has a test program.
This program is primarily used in production in order to test all functions.
The functions provided by the test program allow a quick and easy search for possible
errors on the hardware. On the Nord Stage, the display guides the user through the test
program.

Hardware
Hardware structure
The hardware structure is common for all three Nord Stage products:
One power supply unit, one main board and two panel boards.
Power supply
The Nord Stage is supplied with several different voltages from the power board.
These are +3.3V, +5V and ±12V. For more information on where to measure these
voltages, see the schematic for the power supply. There are also two voltages supplied
from the main board. U46 (23340) supplies the Host and DSP´s with +1.8V, U43 (21540)
supplies the audio D/A with +5V. The Power supply is connected to the main board with
a 10 pole connector P2 (22480).
Main Board
The main board is equipped with five DSP´s U16-U20 (23280),which is controlled by a
host processor U10 (23180) with two DRAM circuits U8 and U9 (23170) (1M*16 bits).
Boot code for the host processor is stored in the BootPROM U6 (23891) (512k*8 bits).
OS and piano samples are stored in a Flash memory U27-U30 U31-U34 (24000)
(16M*16 bits). Various other information, e.g. user settings is stored in an
EEPROM U24 (24147) (2k*8 bits).
Audio D/A conversion is performed by U44 and U45 (23430).
A/D conversion of the control pedal takes place on the panel board 1 U14 (23370).
All input and output jacks are filtered from radio signals with an EMI-filter (23110)
(component designator prefix F). External connectors are two 26 pole connector for the
panel boards P3-P4 (22520),a 10 pole connector for the power supply unit P6 (22480),
two keyboard connectors P1-P2 (22680),one four pole connector for the after touch strip
P5 (23790) and one six pole Picoflex connector for memory card P9 (24152).
Panel Board 1
On this panel board you will find all control functions for the master level/rotor effect,
organ, piano and program section. This panel also holds the LCD (24020), main program
encoder (23720), pitch stick (10295) and mod. wheel connector P8 (22710). The panel board
is connected to the main board with a 26 pole connector P1 (22520).
Panel Board 2
On panel board 2 you will find all control functions of the synth, extern and effects
section. The panel board is connected to the main board with a 26 pole connector P1
(22520).

Clavia DMI Service manual Nord Stage rev. 1.1 Page 8
Hardware configuration
The Stage model (88, 76, compact) is decided by a jumper on pin header P7
found beside the MIDI connectors.
Hardware version is shown on the Stage display when the unit is started.
If the jumper is not properly configured, you get problems like:
- Low trigging sections on the keyboard.
-Wrong scaling on the keyboard.

IImportant Information!
Here is a brief background story.
Since the start of the Nord Stage line, Clavia has accurately picked and tested out the
best units from Fatar’s semi weighted keybed production.
In order to increase the quality level on the velocity sensibility some hardware changes
were made to the main board and a calibration memory card was added to the keybed.
Due to this change, precaution has to be measured when replacing keybeds or main
boards at service.
Pls. see below for scenarios that may occur and how to handle the service matters.
Uncalibrated Units
Nord Stage 88 Serial No from SA10004 to SA11522
Nord Stage 76 Serial No from SB10001 to SB10182
Nord Stage Compact - There are no uncalibrated units
Scenario 1: Main board up to V1.2 needs to be replaced.
Action: Replace with main board (V1.2 or higher) AND a calibrated keybed (with
attached memory card).
Scenario 2: Keybed needs to be replaced.
Action: An approved but uncalibrated keybed must be used as replacement.
Calibrated Units
Nord Stage 88 Serial No from SA11523 and higher
Nord Stage 76 Serial No from SA10183 and higher
Nord Stage Compact Serial No from SA10001 and higher
Scenario 1: Main board must be replaced (V1.2 or higher)
Action: Replace with main board (V1.2 or higher)
Scenario 2: Keybed must be replaced.
Action: A calibrated keybed with memory card must be used as replacement.
In order to get the correct replacement parts, always state the units Serial No and also
the main board Version No that is printed on the barcode label.
NOTE! The small memory card attached to a calibrated keybed must be handled as a
unit and must during any circumstances NEVER be switched or removed from the
keybed. If a keybed must be scrapped, this card must go along with it.

Current OS version is shown in the Stage display when you power on the unit.
I
II
IImportant Update Note
Updating from OS v1.x to v2.16 will make it necessary to update all the piano samples
to Piano Sample Library v2.1. Users of OS v2.00 do not need to update the piano
samples as Piano Sample Library v2.1 is fully compatible with OS v2.16.
