Mixer desk button

A college with a recording studio asked us if we could help with the operation of a particular button on a Mackie Onyx 1620i sound mixer. Users with disabilities were finding the “Talkback” button difficult to press.

The solution

We considered electrically connecting a disability friendly switch in parallel, but this proved difficult due to the nature of the circuitry the button operates, and the desire to make any modification reversible if the panel was ever sold on.

Instead, we took a template off the front panel and constructed an easy to press lockable button to sit over the original, and secured by a couple of longer screws in existing panel securing points.  Construction was a combination of 22mm copper tube, copper plate, and a button machined from an engineering plastic called acetal.

A dense foam pad was added under the new button to protect the existing one and prevent excessive force being applied. A supplementary return spring was also added.

The benefit

The button is not only much easier to press, but it has a twist lock built in so can be locked down.
