Hi Everyone,
A bit of background: I have some experience with the Arduino and I've recently taken a rudimentary electronics class, but I'd like to talk through some questions for a small project that I want to put together using the Teensy 3.1.
Question: What would I need to do to get a signal from the Teensy 3.1's DAC A14 pin to a line level that a mixing board could pick up? Will Teensy's 5 volts be enough to simply connect this pin and the ground on that same side of the board directly into a mixer, or should I consider putting together a simple amplifier (an op-amp I'm guessing?)
From what I've read on the Audio Library forum is that I can probably accomplish what I'm looking for with the Audio Shield, but that I believe I should be able to expect to easily write a signal out to the the DAC on pin A14. Does this sound right?
My goal is to just produce some simple FM synthesis, and I only need one channel of output, so I'd like to try to do it without the shield.
Any advice would be greatly appreciated, or even just a confirmation that my expectations are right (that I can use the Audio library to send a signal out A14 and right into a mixer without any other amplification).
Thank you!
Andy
