4-Ch DSP Amplifier Enclosure for Dayton Audio & Sure boards by zx82net

Last crawled date: 3 years, 1 month ago

This is an amplifier enclosure intended for the Dayton DSPB / KAB series of Class D amplifiers also sold under the brand Sure Electronics Wondom.
It takes two of the boards so it can create 3 or 4 channel amplifier perfect for a stereo set of 2-way speakers with DSP crossover, or a 2.1 stereo system.
The amps can be mounted to the manufacturers purpose made L-brackets, with two of the brackets bolted together as shown, or you can use the adpater, if you don have the L-brackets. (I haven't actually fit tested the adapter, but it should be fine. Just let me know if you hit trouble.)
There is space in the back pannel for 8 terminal posts, the standard 3.5mm socket which comes in the amp accesory pack, and the barrel power socket, which is held in place by a clip and two screws. There are two versions of the clip because I've seen 2 slightly different versions of the socket. I suggest you print both clips and check what fits.
The front face hase a whole lot of mounting holes for switches and pots, so you can choose the layout you want. The facia can be used to cover the unused holes, you can mod it to suit your own control layout.
The lid just clips in, the stand is optional. M3 hardware for mounting the amps, the facia and clip.
Fusion 360 file provided for simple customization.
