Hello All Hackaday maders
I would like to ask and take advice for my idea
I thinked to develop a system low cost for music lovers,
the system have a two audio inputs, 4 outputs, and a desktop application can configure this device to make audio treatement :
- equalizer to correct sound for 4 outputs
- limiter to protect amplifier and speakers
- high pass / low pass (butterworh, bessel ...) for cross over
- routing option : L / R /L + R
I thinked to add USB for interfacing with computer
I thinked in terminal blocks screw for connection audio (with symetric technic)
I thinked to add VU METER for input in face
I thinked to add 4 button switch for fast mute
I thinked to add leds for : clip / mute / signal
I have problem to implement delay because the limitation of DSP
I use DSP :ADAU1401
I use MCU : ATMEGA328P (based arduino uno)
I go to use 65/260 volt power supply internaly
the enclosure is small (like a set top box)
