What is the purpose of a tone control?

Tone control allows listeners to adjust sound to their liking. It also enables them to compensate for recording deficiencies, hearing impairments, room acoustics or shortcomings with playback equipment.

What is active tone control?

While passive tone controls can only cut a specific frequency (and this is typically limited to high-frequency roll-off ), an active tone control can cut and boost several frequencies at a time. This is determined by the number of frequency bands in a given system.

What does gain do on an amp?

Your gain setting determines how hard you’re driving the preamp section of your amp. Setting the gain control sets the level of distortion in your tone, regardless of how loud the final volume is set.

Who is Peter Baxandall?

Peter J. Baxandall (August 11, 1921, Kingston upon Thames, Surrey – September 8, 1995, Malvern, Worcestershire) was an English audio engineer and electronics engineer and a pioneer of the use of analog electronics in audio.

What is Baxandall’s original graph?

Baxandall’s original graph tested the hypothesis that if negative feedback was applied to a distorting amplifier, then the feedback signal would itself be distorted, generating harmonics of distortion harmonics, and that the amplitudes of these new harmonics could be predicted if the amplifier’s transfer characteristic was simple and known.

Why did Baxandall recommend the EF37A over the EF86?

Baxandall recommended the EF37A (precursor to the EF86) because its top-cap grid connection avoided the grid to heater leakage resistance of the phenolic octal base that would otherwise cause hum. Top-cap grids are a nuisance, so possible alternatives are shown in Table 7.4.

What is a Baxandall tone circuit?

Peter Baxandall designed the Baxandall tone circuit or EQ in 1950, and they were then implemented into millions of audio systems around the world. So what is a Baxandall equalizer circuit, and what makes it different than other equalizers?
