Centre Section Cards
Four centre section cards are located beneath the large panel that contains the Talkback and Oscillator controls, LCD
display, and DAW soft keys. These are:
• 629651X3 6-Track Select
• 629652X3 2-Track Select & Monitor Inserts
• 629653X4 Gain and MDAC control/ Talkback and Listen
•
629654X4 Monitor Outputs
To access these cards, first remove the knob caps from the six rotary controls in the oscillator, listen mics etc. area. Now
remove the four screws from the panel. Lift this panel onto its side, taking care not to damage the ribbon connecting it
to the Motion Control panel. Beneath the panel is the metalwork containing the LCD screen. Unscrew the two screws at
the bottom of this and lift it to one side. The cards are in numerical order from left to right: 651, 652, 653, 654.
The remaining five audio cards can be removed in a similar way to the channel strips. In order, from left to right, they are:
• 629928X2 Centre Section Compressor/Mix/Rec/Foldback
• 629918X1 Dynamics 1
• 629918X2 Dynamics 2
• 629919X1 8-Track / Echo Returns
• 629919X2 Aux Bus / Echo Returns
Note: The two Dynamics cards (629918X1 and X2) are electronically identical. Three links (LK1, LK2 and LK3) are fitted
to Dynamics 1 to differentiate between the two modules. For fault finding purposes the two Dynamics cards (629918X1
and X2) may be swapped with each other. When exchanging the two modules ensure that only the module fitted in the
Dynamics 1 slot has links LK1, LK2 and LK3 fitted.
