For added flexibility, the Class D amp also has a variable low pass filter, helping make audio frequency more adjustable according to your subwoofer(s) characteristics and personal listening ...

In a switching audio amplifier, the output signal is a low-pass filtered version of the high-powered PWM voltage produced by a switching power stage. The bottom 20kHz of the signal spectrum is the ...

However, if two different transistor amplifiers have the same smooth, linear frequency response, low distortion, and are operated within their output ratings, then they will tend to sound identical ...

Measuring single-frequency THD+N through a flowgraph in ... or harmonics. Any audio amplifier we are likely to encounter will be far closer to a perfect linear amplifier than that, but even ...

Nisshinbo Micro Devices has announced the release of the NL8902, a high-quality dual audio operational amplifier.

The audio signal is used to modulate a PWM carrier signal which drives the output devices, with the last stage being a low pass filter to remove the high frequency PWM carrier frequency. Classes A, B ...

The brand called it the “ultimate desktop audio companion ... that ensures ultra-low noise and a wide soundstage with a frequency response of 10Hz to 100kHz. Like many of today’s integrated amplifiers ...

This innovative ASIC linear audio amplifier can drive USound MEMS speakers in the frequency range of up to 40kHz, reaching the lowest noise, lowest harmonic distortion, and high rejection of ...

As the most expensive headphone DAC/amp we tried, the THX Onyx has ... gold for hi-res audio over 48kHz, and red for audio with a sampling frequency of either 44.1 or 48kHz. At 8 inches, the ...
