Can you generate an audible sound to be amplified?

You can connect this to a power amplifier only if the output AC voltage matches the input sensitity of your amp. Most amplifiers these days have an input sensitivity of either 0.775 VAC or 1.4 VAC. The manufacturer does not include in their specifications what is the output voltage. Before connecting to an amplifier you will need to measure the output voltage to see if it's enough to feed your amp. If not you will end up frying your amplifier and will need to connect to a preamp before connecting to your power amp. I tried this with a signal generator and learned the hard way. Honestly you are better off purchasing a signal generator and preamp since a signal generator gives you a wide range of wave functions to work with.

Any ideas on how to hook it up to an amp with rca inputs?

Can this generate low voltage square waves (20-40 mV peak to peak)?

one can always place a voltage divider on the output to get very low amplitudes

Can you set this to the Schumann frequency of 7.83 Hz? Can this generator pulse its output?

Mine can only be set in 1 hz increments
