Fitting the PA12 Rack Ears

A pair of 19” rack ears is provided with the PA12. The ears

replace the front and side trims so that the console can be

mounted in a rack, plinth or case. Note that the PA12 can fit

into a standard 19” rack. The ears can fit in one of two

positions depending on how you want to mount the console in

the rack or other furniture.

The top panel assembly needs to be removed from the base to

gain access to the screws that hold the trims and ears in place.

Ensure that you have a suitable work surface with adequate

lighting and clear of any objects which may scratch or damage

the console panels. Tools required include a number 2 Pozi

and T10, T15 and T20 Torx screwdrivers.

1 Remove the 6x M3 countersunk top panel screws. Also

remove the 3x front and 3x rear M3 pan head fixing screws.

2 Carefully hinge the top panel assembly up from the base

as shown. Support the rear so that it does not slip. Unplug the

ribbon harness from the LR circuit card. You can now lift the

panel away and place it inverted on the work surface.

3 Unscrew the 6x 6B pan head front trim fixing screws shown

in the diagram. Take care to avoid damage to the faders. The

front trim including the armrest and carry handle can be

removed.

4 Locate the 4x internal M5 pan head screws fixing each side

trim to the chassis. Remove both trims. Align the rack ears in

the required position and fix these to the chassis using the 4x

M4 countersunk screws provided per side. Ensure they are

done up tight.

5 Check your work and ensure there are no loose parts or

debris in the chassis. Align the top assembly with the chassis

and plug in the ribbon harness. Make sure you align the plug

correctly with the socket. Carefully lower the assembly into

place. Refit the 6x top, 3x rear and 3x front fixing screws.

We recommend you keep the trims and their fixing screws in a

safe place for re-use in the future.

Do not obstruct the side ventilation slots or position

the console where air flow required for ventilation is

impeded. The console must not be operated in any carry or

flight case that obstructs these slots. Ensure adequate air

flow when rack or plinth mounting the console.
