BD30 DIY
High quality DIY 30 Watt mono plate amplifier designed primarily for use in combination with our bass systems.
Each mono amplifier is built on a solid 4mm thick aluminium base plate (250*135mm). The power supply (110-220V selectable) features a shielded 300VA torroidal transformer plus 12(!) Black Gate NX Rubicon power caps wired in 'Super E-Cap' configuration to give optimum results.
BD30 DIY "plate" amplifier...
While designed as a woofer amplifier, the BD30 amplifiers are so good that you can also use them as main amplifiers for our "Quasar" or our other high resolution systems, and also as a budget solution for powering our "ORIS" horns. These amps are quick, clean and dynamic but also musical and without typical annoying solid state characteristics.
The relative small overall dimensions make the amplifiers suitable for mounting in the stands for the Oris horn. A simple wooden cover screwed to the aluminium plate with the same finish as your bass enclosure is the perfect solution for achieving a great look, minimal visibility and the shortest possible wiring. A wooden cover such as the examples shown below is easy to build. The ones shown were made of MDF with veneer. As you can see, you can build them for use as stands below the Oris horns.

You can find more information about building the amplifiers and the stand/housing on the BD30 DIY-manual page.
Safety note: While completely electrically safe if properly assembled, some wiring of the BD 30 amplifier has to be soldered to connections that will be hooked up to your mains power supply. This means that you can be exposed to high voltage (110-230V) if you do not take appropriate precautions. Therefore you always must have the mains cable unplugged from the amplifier while you are building it and, subsequently, before you open the cover for any reason!
