Hi there quick one for you folks
Just curious about one thing. While testing the gear I build, I use the following setup: Output of my apogee ensemble to the input of whatever I build, let's say, a compressor, and the output of the compressor to the input of the apogee. I open up a session in Logic pro, set my in/out plugin to rout the compressor and then, open up a freq. analyser plugin (Melda) to take a look at the general audio frequency and all other stuff.
Anyway, The first thing I do is to only plug the output of the compressor to analyse the noise. There is always that 60hz (I'm in canada) bump, while no signal passing through of course, just looking at the noise of the circuit. What is that 60hz? Hum from the main ac? I don't hear any hum, and of course, while pluging the input and passing a signal, let's say a sine wave or a pink noise, there is no more 60hz bump.
Just curious what it is. Maybe I'm just looking at the main hum from the circuit, and while looking at the meter, I generaly see some -92db signal (noise), depending of the gear i check.
Again, just curious
