Audio Amplifier Power Supply Calculator

The amp must supply only the desired volume in the desired quality with your loudspeakers.

Audio amplifier power supply calculator. The real output power watts of an amplifier is the result of the maximum voltage and amperes available from the supply rails and the speaker impedance r. Psu for 5 1 amplifier. It is technically possible to build an amplifier with only 30 watts that is better than a 200 watt amplifier with same low volume level. For example two 8 ohm speakers in parallel have an impedance of 4 ohms.

Power supply current calculator. Definitions are below the amplifier power calculator. Based on input variables it calculates the maximum peak to peak and rms voltage that the amplifier would be able to achieve then applies that voltage to output impedance to get the rms output power and peak current numbers. 28th august 2011 07 59 am.

In that case each speaker would receive half of the amplifier s 4 ohm power. 23rd march 2010 03 58 pm. This is a modelling tool for a b class audio stereo amplifier power calculation. It allows you to integrate 4 35 mm snap in capacitors of your choice 10 mm pin capacitor spacing.

This audio amplifier power calculator will help you pick a power amplifier with enough watts for your application. Enter the total power output of all of your amplifiers length of the power wire wire gauge you intend to use battery power supply voltage and amplifier efficiency below. Class a b amplifiers most amplifiers are generally 50 60 efficient at. The amp s power supply voltage limits the maximum amplitude of the waveform it can output.

Extron provides a series of audio calculators that sound system designers engineers and technicians frequently need to access such as determining amplifier power requirements converting between dbu and dbv or volts or estimating the loss in sound pressure level with an increase in distance. Use the sliders to set the variables and the calculations in watts will be shown below the orange line. This dedicated linear power supply circuit is ideal for designing stereo diy amplifiers. 25th april 2007 01 08 pm.

Three channel amplifier w psu. Class d amplifier compensates for psu. Amplifier output power is limited by voltage current and temperature. Amplifier psu design needed.

16th december 2009 10 12 pm. The package contains the pcb 2 diode bridges rbv5006 and 4 screw terminals. In audio electronics there are several methods of measuring power output for such things as amplifiers and power handling capacity for such things as loudspeakers. On the crown website is a calculator that determines the amplifier power required to achieve the desired spl at a certain distance.
