The amplifier has a control for bass/treble (whose functionality (but not implementation) resembles that of a Baxandall circuit), two volume controls for microphone and instrument, and three controls for the echo circuit, but the delay time is not adjustable. The amplifier is delicate and requires a lot of maintenance: tubes run hot, and the ...
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.
The Fender Bassman was the first amplifier to standardize the tone stack design. Dubbed the 5F6-A from the Fender model number of the amp which first used it, this tone stack offered the performer the ability to control the amplifier's low, mid, and high frequency response independently.
The first models Leslie manufactured were the 900 and 910, [37] which contained a 100 watt, three-channel power amplifier. Both could split into two sections. [38] The most popular version of the Pro-Line series was the 760. It was a smaller version of the 900 and 910, and contained a 40 watt treble and 50 watt bass amplifier. [39]
This article lists manufacturers of bass amplifiers, loudspeakers, and other amplification-related items such as preamplifiers. The amplifiers and loudspeakers used to amplify bass instruments (e.g., the bass guitar, double bass and similar instruments) are distinct from other types of amplification systems due to the particular challenges associated with low-frequency sound reproduction.
[a] The bass and treble controls in a hi-fi system are each a first-order filter in which the balance of frequencies above and below a point are varied using a single knob. A special case of first-order filters is a first-order high-pass or low-pass filter in which the 6 dB per octave cut of low or high frequencies extends indefinitely.
Delay is an audio signal processing technique that records an input signal to a storage medium and then plays it back after a period of time. When the delayed playback is mixed with the live audio, it creates an echo-like effect, whereby the original audio is heard followed by the delayed audio.
Baxandall's bass and treble control circuit, when made public in Wireless World (1952), "swept all others before it". [2] An early version of the design had already won him an award in 1950 (a $25 watch) at the British Sound Recording Association, a predecessor of the Audio Engineering Society. The design is now employed in millions of hi-fi ...
