Witryna2 lis 2024 · The lower the THD rate is, the less distorted the sound. Most mixers and pre-amps present a THD rate of 0.01% or lower. Amplifiers usually bring the THD up to 0.5%. The THD may vary according to the frequency – the higher the frequency, the higher it’ll be. To sum up, when recording with high gains, pay attention to the THD! WitrynaValues for line attenuation on a DSL connection are typically between 5 dB and 50 dB -- the lower the values, the better.
