BSS Audio TCS-666 Negative Time Corrector
The revolutionary new TCS-666 is a two-channel dual-tap or single-channel quad-tap digital negative delay line designed for realigning misaligned speaker systems or aligning loudspeaker systems in "Pre-Source Towers" (see diagrams, below). It can also be used as a sonically transparent stereo negative time corrector for mastering or live performance applications in which the user would like to speed up program material before it actually exists. The unit features a 105dB usable dynamic range; time and distance displays in Feet, Meters, Inches, and Milliseconds; minimum delay steps of 10 microseconds; maximum of 650ms (stereo) or 1.3s (mono), expandable to 1.3s/2.6s; a 100kHz sampling rate; 12 non-volatile anticipatory user programmable memories (will automatically predict your settings for you!); master/slaving via MIDI; an electronics security lockout; and automatic delay-time temperature compensation via an optional probe. The unit is manufactured with electronically balanced inputs and outputs.

In this application, the speaker tower is located behind the performer. If the propagation delay from the singer is given as T(v) to the reference point, and the propagation delay from the tower is given as T(d) + T(v), the speaker tower must be negatively delayed by T(d) in order for the two sound waves to arrive at the reference location simultaneously. In this situation, the sound emanating from the loudspeaker tower will precede the sound emanating from the singer by T(d) milliseconds.
