Does Wall Voltage Matter for Audio Amplifiers??

In this test I am using a Powersoft X4 power amp to create "wall voltage" and power up a Crest 4801 power amp. Then I test the impact that lower and higher wall AC voltage has on the amp output power. In this video, Dave Rat tests the effects of underpowering the AC voltage to an amplifier while changing the frequency from 60 Hz to 50 Hz. He found that input voltage matters for audio amplifiers, and a decrease in voltage leads to a decrease in power output. At 80 volts, he loses half the power of the amplifier, and at 200 volts, the output is almost three times the amount produced at lower voltages. Low voltage rails can negatively affect sound quality in guitar rigs as they won't feed back and distort at the necessary point. Dave Rat considers additional videos to investigate if amps sound different in Europe, which has a 50-hertz frequency, compared to the US, which has a 60-Hertz frequency. Dave Rat tests the effects of powering up a power amplifier using a power amplifier and a frequency generator. He uses a Powersoft X4 to power up a Crest 4801, and he tests what happens when he underpowers the AC voltage to an amplifier while changing the frequency from 60 Hz to 50 Hz. Tests different voltages and their effect on audio amplifiers. At 80 volts, he loses half the power of the amplifier, but that loss is only 3 db, which can make a significant difference in sound quality. When the voltage is increased to 200 volts, the speaker notes a 624-watt output, which is almost three times the amount of watts produced at lower voltages. He states that low voltage rails can negatively affect sound quality as guitar rigs won't feed back and distort at the necessary point. Thus, AC voltage rails make a significant difference in sound quality. The speaker contemplates doing additional videos to investigate if amps sound different in Europe, which has a 50-hertz frequency, compared to the US, which has a 60-Hertz frequency. 00:00 Intro and description 01:02 The tests 01:58 Thank you to members and subscribers 02:53 The amps - Crest 4801 powered by Powersoft X4 03:25 Powering up 04:25 Power test at 120V 60hz 06:30 Power test at 110V 60hz 07:19 Power test at 100V 60hz 08:08 Power test at 80V 60hz 09:00 Calculating the power 10:37 Power test at 135V 12:08 Calculating the power 13:04 Power issues with guitar and bass amps 13:43 Outro If you like this and other videos I do, please join this channel to get access to more videos, early access to videos as well as to be able to join my weekly zoom chats:    / @daverat   Also check out: https://www.ratsoundsales.com/ https://ratsound.com/daveswordpress/ https://www.ratsound.com/ http://www.soundtools.com
