6 FAQs about [Is lithium battery a good choice for power amplifier power supply ]
Do I need a battery powered amp?
There are times, especially when playing outdoor, when there is no AC power available. For those times it would be nice to have a battery powered amp, or a DC to AC converter you can connect to a 12 volt battery. Battery powered amps seem to always have very low wattage output, with small speakers and don't sound very good.
Do amplifiers need an ups?
Amplifiers do not need any UPS as they convert power to DC (bus voltage). Any usual spikes (caused by inductive load turn-off) would not even make it through the highly inductive transformer. However, there may be advantages to powering equipment with HDMI ports from an online (preferable) UPS. Ups + anything audio =. Bad bad bad bad bad
What is a good power supply for a hifi amplifier?
So ultimately, the primary characteristic needed is stability, all things considered, the power supply should have no effect on the amplified audio by way of fluctuations in DC potential available to the amplifier circuitry. Practical power supplies for HiFi amplifiers could be linear, switch mode or (less practically) batteries.
Where can I find a good article on amp power supply?
