Amplifier Audio Measurements As usual we start with our dashboard: View attachment 45907 Per warm up test, we see one channel with higher noise floor and differing distortion products. Averaging the two channels still puts the P502 well above average amplifier: View attachment 45909

sine wave signal onto the power bus, and the audio analyzer measures this ac voltage at the APA power pin and at the k V SVR V OUT ac S = 20log PSRR V V OUT dc S = 20log ∆ ∆ output. Here the analyzer, an Audio Precision System–II, is configured for a crosstalk measurement1, 2; it sweeps the ac voltage at constant amplitude over the audio band,
A DIY approach to distortion measurements for audio amplifiers

The amp being measured needs to drive a load, so a dummy load simulating your speaker load needs to be made. All that is required is a resistor that has the same impedance as your amplifier and is rated to handle the amp’s power output. I chose a 8Ω 50W power resistor from RS Components. You may wish to heatsink this but I bolted it directly to a metal case.

There are many key aspects to amp quality that are either not commonly reported on (ie, slew rate) or are not measurable. From basic stats, shoot for SNR above 110, and THD below 0.03 (with the understanding tube amps will be skewed to the worse).
Using Sound Cards for Audio Measurement - Audio Precision

For example, to conduct quality control of speakers on a manufacturing line, you typically need to make measurements from about 80 to 114 dBSPL. With typical measurement microphone sensitivities, you do not need to acquire input signals much higher than 1 Vrms in amplitude. You do not need the 230 Vp maximum input of an APx555 audio analyzer. Many …
NwAvGuy: Op Amp Measurements

ALL THE SAME: Here’s a list of measurements that were essentially unchanged by any of the op amps and why: Frequency Response – The 220 pF feedback cap determines the upper –3 dB point (~250 Khz) with all the op amps and the... Slew Rate – All were over the 2.8 V/uS requirement for the O2. Put ...

The Fifteen's input impedance measured under 76k ohms, balanced and unbalanced. Its output impedance was under 0.017 ohms at either 1kHz or 20Hz, increasing to (or under) 0.045 ohms at 20kHz. Gain into 8 ohms measured 23.3dB balanced (interestingly, the unbalanced gain measured 6dB higher, at 29.2dB—opposite the normal condition).

Regarding Noise measurement, the best equipment for measuring low-level noise in quality HiFi amps, Pro Audio Equipment, etc is to use specialist Audio Measurement Equipment, because to achieve the resolution required in the converters (typically 24-bit) and the ultra-low noise floor in the input stage, the Measurement Equipment needs to be limited to Pro-Audio …
