To install these products you will need to be a competent person with some basic knowledge of Electronics and the internal workings of your accordion.
The above pictures also give an idea of how to install this system.
There are no instructions provided.
The system comes already pre-wired.
It may be necessary to simply adjust the length of wires to suit your accordion's size by cutting and re-joining them.
The system has a long board that should be installed under the grill of the right side of the accordion using the supplied sticky tabs. The volume controls for both right and left sides should be installed in the grill on the right.
The jack socket should be installed in the grill, usually on the bottom so the external cable doesn't interfere.
The wires need to be fed through the inside of the accordion by drilling a small hole, feeding through the cable and taping to the insides of the bellows, allowing for the movement of the bellows.
You must remember to seal properly around the holes in both sides of the accordion where you make the holes for the wires. You don't want air leaks!! You can use bees wax or some quick drying super glue.
The battery is installed inside the left side of the accordion, as is the left hand mic.
A standard 9v battery will usually last around 6 months to a year on these systems. Subject to usage.
The pictures speak for themselves.
The circuit board on the right hand side is 18cm long (7 inches long)
These systems are fantastic. Low feedback (if any). Great natural, non directional sound.
The choice of the true professional.
