Hi,  
QQ. I have a Logic Pro 8. Can you let me know what the maximum input voltage is on the analog channels. I’m seeing input topping out at ~10.3V

Thanks  
Dean

There is slight variation from channel to channel, but the voltage range limits are a little wider than +/- 10V. The inputs are advertised at +/- 10V, however after calibration, the voltage ranges are a little wider.
