Painting the subwoofer
The C-range cabinets are made of plywood coated with Mach Safecoat and can easily be painted to match the color
scheme of your venue.
To paint your speaker:
1. Remove the front grille
2. Degrease the cabinet on all surfaces with denatured alcohol/methylated spirit
Warning: Use of other types of cleaning chemicals can damage the cabinet and should be avoided
3. Mask all areas that should remain unpainted (tweeter, woofer, switch, terminals, reex port etc)
4. Paint the speaker with Etching primer 2K, P565-713, chromate-free, or a similar product
5. Let the primer dry
6. Apply paint in thin coats to speakerand grill using a paint spraying device
7. When spraying the grille be very careful not to ll any holes, as this will have a serious impact on sound
quality
8. Let the paint dry
9. Remove masking
10. Put the grille back in place

Maintenance of the subwoofer
Although subwoofer systems normally only require very limited maintenance there are several things you can do to
ensure that your Mach system sounds as good 3 years after installation as on the day you bought it:
Never overload your system – stay within the specied limits for power handling.
Always keep the speaker clean and dry.
As with any electrical product, currents will accelerate corrosion of metal surfaces. Therefore, it is recommended to
check the terminals for corrosion at regular intervals, especially if the speaker is mounted in a hostile environment
(high humidity, airborn salt, etc.).
How to remove the grille
Remove the screws in the grille and pull the grille out. When replacing the grille do not over-tighten the screws.
How to change the woofer
Remove the grille, then remove the screws in the woofer and lift the woofer out of the cabinet. Carefully disconnect
the wires and connect them to the new woffer, instal the woffer in the cabinet and reinstall the grille.
How to remove the terminal module from inside of cabinet.
Remove the grille, then remove the screws in the woofer and lift the woofer out of the cabinet. Loosen the eight
screws and pull the terminal out. Note the positions of the wires, then carefully disconnect the wires from the
transducers.
