Hi there,
I'm working on a project to take a line out signal from an audio source, and convert it into a dmx signal that has 10 steps from 0-5 v, in 0.5v increments.
I need to filter the input to get a rough apprixmation for bass, midrange and treble. There will 3 dmx signals, each controlling a lighting display.
The circuit layout is as follows..,
Input signal (line out) -> Filter -> Analogue - Digital Conversion -> ? -> DMX input
I'd like to know your advice on what way to filter the audio line out signal, since each filter will be processing the same signal. Could I use something like an audio crossover for example? Simpler the better.
Analogue - digital conversion could be tricky since there needs to be only 10 steps into the DMX input. Would be ideal if it were in 0.5V steps
? (may be needed, dependant on the A-D section) converts the output from the A-D into the 10 steps 0-5V, in 0.5v steps.
Any advice on what approach to take is very welcome.
Thanks!
