Answer: Link: please read the info at this link
|Version||Date||Airence PCB info and modifications|
|V.2||14-01-2014||Airence 1C > Airence 1D: Added Mic-on 2 circuit at Extender|
|V.3||18-11-2014||Airence 2D > Airence 2E: USB noise reduced at Main|
|Airence Main and Extender fronts with Powder Coating|
|V.4||20-01-2015||Airence 6E > C20, C38, C39, C40 replaced by 0R (wire), to prevent distortion at Announcer and Studio output|
|V.5||29-04-2015||Airence 9B > Added 8x 100K resistor, protection for peak voltages when connecting a powered Extender|
|Airence Main new fronts without Master faders|
|V.6||28-05-2015||Airence 9B > C64, C65, C66, C67 replaced by 0R (wire), for better ground connection|
|Airence Main and Extender remove powder coating at 15pin Sub D connector, for better ground connection|
|V.7||Airence Main 4, 5 and 6 pcb > SMD with different ledbar drivers|
|Airence Main Added Digital option|
|Airence 3 (Telco) > SMD with added Ring signal to Start jack|
|Airence Main Added 100N capacitor to remove Fader start noise in Audio|
| Airence V7 (Telco, Voip, Master 4, 5 and 6 pcb) not compatible with older versions due to Communication buss and Digital option.
You'll have to replace the complete set except Airence 6 and 7!
|V.8||Airence 3 (Telco) > R15, R17 replaced by leaded 600mW Resistors R17-R18 modification|
|V.9||Airence 3 (Telco) > R15, R17 replaced by SMD High power|
