Yes, an amplifier can drain your car battery when the engine is off. Amplifiers require power to function. When they are connected to the battery, they draw a current even when the vehicle is off.

I want a single power supply to both, charge my Battery in my speaker dock, and also run the Amp when plugged in. I could have a 3-Way switch so the batteries and PSU aren''t powering the AMP, but I''m just wondering how to safely charge a SLA battery AND power a 12V Amp with the same unit. Thanks again for all the input.. I haven''t

Customer ServicePart 7. 12V power supply vs. 12V battery: what''s the difference? A 12V power supply and a 12V battery may both deliver the same voltage, but they serve very different purposes. A 12V power supply is usually AC-powered, providing a steady, continuous current ideal for stationary devices that need a constant power source.
Customer ServiceYou will find a pair of stereo line outs at the back of the amp, which connect to balanced or unbalanced jack plug leads, together with a USB socket and a power socket for the THR30iis laptop-style power supply. The biggest drawback that this amp has is its battery life. With an internal rechargeable battery in the THR30ii, it only has a measly five-hour battery life

For reference measurements amplifier can be powered directly from a laboratory power supply or battery. Figure 6. Test Setup Measurements were done in three steps: 1. Measurement of the amplifier using ±3-V battery as a
Customer Service4 天之前· Amplifiers require power to function. When they are connected to the battery, they draw a current even when the vehicle is off. This power drain can lead to a dead battery if the amplifier is not designed to go into a low-power standby mode. Many aftermarket amplifiers only draw a small amount of current, but over time, this can accumulate and

Customer ServiceAt its essence, an amplifier is just a power supply whose output (normally d.c.) is wiggled by the rest of the amp circuit, and then passed to a speaker. So the power supply is "in the signal path," even if indirectly, and influences the sound/response of the amp.
Generally, the classification is based on the variant of the signal. If it is of small-signal then these amplifiers can be utilized in the pre-amplification of the signals or as instrumentation amplifiers. While in the large signals amplifications the power must drive the load. Hence these are known as power amplifiers.
This is a simple power supply for an audio amplifier circuit. It is a fixed regulator with multiple output voltages of 12V, +15V, -15V, +35V, and -35V. It uses the principle of Zener diodes and IC-regulators for steady voltage output. Ideal for 50 Watts to 60 watts OCL power amplifiers.
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
You may supply most equipment from such ups , but when operating from battery,they produce some sound few khz ,maybe more , which is part of their pwm operation. This needs to be good filtered if using with audio loads ,because mostly pattial filtering is performed by ups output transformer itself .
