Web9 Sep 2024 · Mark Tillotson said: 0.03% is -70.5dB, 0.09% is 61dB, so a possibly detectable difference given the ear can sense. That's also my experience. For crossover distortion, … Web7 Nov 2024 · THD and THD+N Distortion plots vs. power are shown below, measured at 20Hz, 1kHz and 6kHz. Please note they are almost independent of signal frequency. Maximum power is limited by the 100VA transformer in the linear power supply. The amplifier gave 130W/4ohm/1kHz with THD+N = 1%. Fig.10. THD and THD+N at 20Hz …
Web1% is audible distortion. 10% thd is a crime against music. Usually that spec is given at a certain amount of power output. The amp section may have .1% thd at 10 watts per channel then ramp up to 10% at 12 watts per channel so it depends on how loud you turn it. These are guesses without measuring it but if you can hear distortion turn it down. Web1 Dec 2014 · Sweet sounding second harmonic distortion in the power tube increases and not-so-great sounding third harmonic distortion decreases dramatically. This is why it's worth experimenting with different speaker loads, you may like the tone you get. ... For tube amps a low mismatch is typically safer than a high mismatch. The opposite is generally ...
WebWhen implemented according to data sheet the THD of the LM1875 power amplifier vs. output power shows a peak at about 0.5 watt (0.05% THD into an 8-ohm load and 0.1% THD into a 4-ohm load). The THD drops with increasing the output power and reaches its minimum of 0.02% at around 10W into 8 ohm.
