Bypass (audio)

Source Direct is a drum and bass producer from St Albans in the United Kingdom, consisting of Jim Baker. Source Direct are often compared with ambient drum and bass artists such as LTJ Bukem and other Good Looking Records producers, but their work displays a much darker sonic landscape with more of an emphasis of percussive assaults of syncopated breakbeats.

Source direct, also known as tone defeat or bypass is a sound engineering term. It describes a feature on a piece of audio equipment which allows the audio effect such as bass and treble controls to be bypassed, leaving the sound unaltered by the equipment. This has two functions:

• It allows the effects unit to be bypassed without the need to unplug it
• It allows the isolation of part of a piece of equipment, such as an audio amplifier's tone controls, without affecting the rest of the functions.
