IDENTIFICATION SYSTEM 06th February 2007
Section A
1. MAINBOARD IDENTIFICATION
There is a key resistor called “Rk” on the ampliers mainboard; it allows you to identify which PCB it is and
to nd the proper electric diagrams and components layouts for it.
How to nd the right diagrams to refer to
1) Find “Rk” resistor on the mainboard and determine its value.
2) Please check the item “Rev/Rk” in the cataloguing information table; then select the diagrams where
“Rk” value corresponds to the pre-determined one.
Example:
“Rk” resistor assembled
onto mainboard, its value
is 10 Ohms.
Caution
When “Rk” resistor is not onto the PCB, you will nd “ - “ in the diagrams instead of its value.
Consult the diagrams where you can
nd 10 Ohms value in item “Rev/ Rk”
Part 1A page 1
2. MODULES IDENTIFICATION AND REPLACEMENT
Besides the module identication name, you can usually nd a number (indicating version) and a letter
(indicating revision) onto the PCB.
By decoding these two gures, you can handle the compatibility of the modules you have to replace and
nd the corrisponding diagrams.
Example of how to decode the modules VERSION / REVISION.
LRx2CD-S.0A
LRx2CD-S = Module type
.0 = Version number
A = Revision letter
(If this letter is missing, it means the module is the rst release).
VERSION NUMBER
A different number indicates a non complatible VERSION.
Please don’t use modules with a different VERSION NUMBER for replacement, unless it is indicates.
Contact Audison for any necessary clarications.
REVISION LETTER
A different letter indicates the module improved revision. Compatibility is not compromised. It is always
suitable to replace a module with another one having the same letter or the successive one.
How to nd the right diagrams to refer to
1) Find the version/revision identication gures on the module.
2) Please check the item “Rev/RK” in the cataloguing information table; then select the diagrams with
corresponding version/revision gures.
Example:
Date: Sheet:
Type: Rev/Rk:
29/mar/2006
LRx2CD-S .0A
Consult the diagrams where you
can nd “.0A” in item “Rev/Rk”.
Version / Revision
corresponding to “.0A”.
LRx2-CD.0A
Date: Sheet:
Type: Rev/Rk:
