Instead of attaching it using the mounting flange, we have had good results with using stick-on velcro.
This is the BomeBox with a mounting flange.
This is the same versatile MIDI/USB/Ethernet/WiFi router and processor, now with an easy mounting plate.
The BomeBox is the solution for connecting and mapping devices via MIDI, Ethernet, WiFi, and USB (without the need of a computer). Cross-connect USB-MIDI devices (powered by the BomeBox), MIDI 5-pin DIN, other BomeBoxes, Allen & Heath professional mixers, and computers. In conjunction with the software editor Bome MIDI Translator Pro, you can fully use the BomeBox’ powerful MIDI processing engine in a robust, self-contained device.
Bottom plate’s dimensions: 146mm x 96mm (5.76″ x 3.78″).
Mounting holes are designed for M3.5, M4, or M4.5 (#6 – #8) screws.
The mounting holes centers are spaced 68.6mm x 134.2mm (2.701″ x 5.283″).
Each side also features a slot for a mounting strap (or small screws).
All other specifications are identical to the regular BomeBox.
