Output impedance – PS Audio

If the input impedance of your power amplifier is 10k then the output impedance of your DAC or preamp feeding it must be at least 1k and better if it’s 100 Ohms or less. If it’s 100 Ohms you’ll only lose a tiny amount of signal at the junction between the preamp and the amp – 100th of what you are sending, just for understanding sake (not entirely accurate but you get …

In audio devices, impedance is the measure of the resistance of a circuit to alternating current (audio signal). It’s measured in Ohms. The “Z” symbol represents impedance. All audio equipment that receives an input and has an output will have impedance measurements, namely input, and output impedances. More on that later.

Output impedance may be determined using this simple technique: A load resistor is used to load the signal source. The output voltage is measured first with full load (V1), then without the load (V2). Just fill the values you get plus the resistance value to the form above to get the output impedance value.

"Measuring the output impedance by means of a burden": Suppose there is a 100 watt amplifier. Then the output voltage at half power is P = 50 W = V 2 / R. Loudspeaker impedance = 8 ohms. V = √(P × R) = √ (50 × 8) = 20 volts. (You can also use 10 V.) Give a sine voltage of 1 kHz to the amplifier input, until we get 20 volts at the output.

1: Measure the output voltage without a load (400Hz sine for instance) 2: Now connect the potmeter with the wiper and the low fixed part in parallel to the source (it will be a variable load) and rotate the potmeter till you get exactly half of …

Two analyzer inputs, configured as analog balanced, are used to make the measurements: One channel measures voltage across the sensing resistor (V sense), and the other measures voltage across the speaker (V spkr). The power amplifier provides the ultra-low output impedance and high current necessary to drive low impedance speaker loads.

How do you measure output impedance? The best way for you to measure the output impedance of your amplifier is through a digital multimeter. In case you didn’t know yet, a digital multimeter sends out a small DC current to measure resistance. You see, impedance is a quality of AC circuits, but that will not measure impedance directly.

Connecting a resistor to LTSPICE circuit and finding its value at 50 % output gave the output impedance around 3250 Ω. The author mentioned that theoretically if you were to feed 1 V signal into the output, the ratio between the forced voltage and the current drawn will give you the output impedance. This gave me again around 3K3 Ω.

T.Rainman Acquaintance. put a 1kHz tone on it, measure the output voltage without a load, then apply a low R load (say 10 Ohm) and measure the voltage again. Make sure the test voltage is low (say 0.1V) to avoid current limiting which will skew the results.
