Solved! How much power does my audio amplifier consume?

[Obsidian90]

Hi all,i've recently purchased a Akai AM-U210 audio amplifier and was wondering how much power does this thing draws from the wall.
Below are all the specs:

Power output: 30 watts per channel into 8Ω (stereo)

Frequency response: 5Hz to 80kHz

Total harmonic distortion: 0.05%

Damping factor: 25

Input sensitivity: 2.5mV (MM), 150mV (line)

Signal to noise ratio: 80dB (MM), 100dB (line)

Channel separation: 35dB (line)

Output: 150mV (line)

Speaker load impedance: 4Ω to 16Ω

Power requirements: 220v,50hz

Dimensions: 440 x 100 x 247mm

Weight: 4.9kg

Depends on how loud you play it and speaker impedance. Speakers with less impedance will be louder as lower wattage so you will probably run them at less power. You would need to get a wattage meter and hook it up to the amp to check it. About the same power draw as a computer in use, depending on how much work it's doing.

Power supply schematic shows a 1 amp fuse.
The maximum amount of power it can draw would be limited by that. If your AC is 120v then multiply that by 1 amp to get 120 watts.
Under normal operation it may vary from 2-5 watts up to maybe 100 watts at full volume.
