How powerful is this amplifier? Answered
I bought this amplifier kit and I'd like to know what its capabilities are. I was going to make a Chu Moy headphone amp but remember that I bought this a while ago and never did anything with it. I'm going to guess that this isn't a top-notch amp, but I was wondering what I could get away with by using this.
music power output: 7W / 4ohm
RMS output: 3.5W / 4ohm or 2W / 8ohm
total harmonic distortion: 0.05% (1W / 1kHz)
frequency response: 20Hz to 20kHz (-3dB)
signal/noise ratio: 86dB (A weighted)
input sensitivity: 40mV / 150Kohm
overload and short-circuit protected
supply voltage: 15V DC (8 to 18V DC possible) / 0.5A
dimensions: 2.2 x 1.4"
I'm assuming that this would be good enough for use as a headphone amp? Would I be able to run this off a 9V battery?
