Modern systems have far wider potential bandwidth. An essential feature of all cutting amplifiers—including the Neumann cutting amplifiers—is a forcibly imposed high frequency roll-off above the audio band (>20 kHz). This implies two or more additional time constants to those defined by the RIAA curve.
Stereo 31-band 1/3-octave graphic equalizer for use in sound reinforcement applications. In the graphic equalizer, the input signal is sent to a bank of filters. Each filter passes the portion of the signal present in its own frequency range or band. The amplitude passed by each filter is adjusted using a slide control to boost or cut frequency ...
Scholz Research & Development, Inc. was the name of the company founded by musician and engineer Tom Scholz to design and manufacture music technology products. Scholz is an MIT-trained engineer who developed many of his skills as a product design engineer working on audio-production equipment at Polaroid in the early 1970s.
Tone control is a type of equalization used to make specific pitches or frequencies in an audio signal softer or louder. It allows a listener to adjust the tone of the sound produced by an audio system to their liking, for example to compensate for inadequate bass response of loudspeakers or earphones, tonal qualities of the room, or hearing impairment.
An idealized and extreme smiley face curve shown using a 29-band graphic equalizer. A smiley face curve or mid scoop [1] in audio signal processing is a target frequency response curve characterized by boosted low and high frequencies coupled with reduced midrange frequency power.
The equivalent rectangular bandwidth or ERB is a measure used in psychoacoustics, which gives an approximation to the bandwidths of the filters in human hearing, using the unrealistic but convenient simplification of modeling the filters as rectangular band-pass filters, or band-stop filters, like in tailor-made notched music training (TMNMT).
These changes increased the headroom of the amp and brought it more inline with the non-reverb versions. This was complemented by the added functionality of a master volume and a push/pull boost. Some later Bandmaster Reverbs also added a 3-band EQ on the Normal channel and a bright switch but this was uncommon across all models.
Audio signal flow is the path an audio signal takes from source to output. [1] The concept of audio signal flow is closely related to the concept of audio gain staging; each component in the signal flow can be thought of as a gain stage. In typical home stereo systems, the signal flow is usually short and simple, with only a few components.
