Description
Experience Level: Expert
We're looking for someone to design/develop a circuit to switch MADI (Multichannel Audio Digital Interface) connections between 2 independent sources and 1 output.
We have prototyped the design using a protoboard with success however are looking for someone with more of an experienced electrical knowledge to look over our design and make any suggestions/improvements as necessary, as well as to provide a final design schematic and PCB design/files ready for manufacturing.
MADI is a digital protocol used to transport audio, we are currently using a relay to switch the between the 2 sources individually to the output, however are worried this might not be the best solution in terms of electronic shielding and reliability (eg. audio drop outs etc.) so would be looking at appraisal on what may be the best solution here.
The design must incorporate
- Connections for 2 power supplies for redundancy, with connections for external enclosure mount LEDs to monitor the power supplies output. No need to incorporate PSUs on the PCB, just either solder tabs or 5.5mm x 2.1mm DC Jack Connections.
- 1 x 5v DC Output (5.5 x 2.1mm Jack), (this can be soldered to the PCB, not external)
- Connections for an externally mounted illuminated SPDT Switch which will be used by the user to switch between the MADI sources.
- Connections for external enclosure mounted LEDs to monitor which MADI Source the PCB is outputting.
- Connections for a 'remote' switch to switch between MADI sources, this will be a simple latching button, only the solder/tab connections for wires are needed on the PCB for this
Images of the project and initially schematic attached.
