LIFT is a single switch solution to recording low signal levels. Developed by Ivor Drawmer it is seamless in
it's operation, LIFT is, in essence, a low level dynamic gain module which has no effect on signals above 0dB,
but increases gain dynamically on levels between 0dB and -30B, up to a maximum of 10dB, and then
continues to add 10dB of gain to signals below -30dB.
You may ask yourself: why would this be necessary? When
recording very quiet passages the most common answer to
obtain a loud enough recording is to simply add more gain,
however, as this occurs throughout the entire audio level
range, increasing the loud signals also, clipping and
distortion can easily occur. The cleverness of the LIFT switch
is that it dynamically increases only the volume of the very
quiet signals below the threshold of 0dB, leaving anything
above untouched, meaning that no unnecessary clipping
occurs during loud passages.
If done crudely the effect would be obvious and unnatural,
however the paramaters of the 1972 LIFT feature have been
fixed at settings that provide as transparent, smooth and
musical quality as possible, whilst making the operation as
simple as a single switch press. The feature will find many
uses in the studio, radio, TV sound, conferences and public
address. It is of great value on piano, drum ambience as well as other types of percussion, and on all vocals
including speech. Mic technique is used to compensate for vocal intensity and one can often see singers
move closer to the mic during quiet passages. LIFT reduces or even eliminates the need to do this.
Please note that, just like any other gain increase, the noise floor will also be increased by 10dB, and in
addition, in a live situation, acoustic feedback is more likely to occur and should be considered during sound
check.
