les Transient Designers

Transient Accenting is unique in that it allows the operator precise control over the amount of enhancement applied to each channel of processing.

The secret is something that SPL call Differential Envelope Technology (a registered trademark of course!), which works by using two envelope generators for the attack and two more for the release. On the attack side, one generator follows accurately the original signal amplitude while the second does the same thing but with a slower attack. Subtracting these envelopes produces a control signal that can be used either to increase or decrease the level of the audio depending on whether the Attack control is turned clockwise or anticlockwise from its centre position. A similar methodology is used to derive the release control envelope. The outcome is that any attack transients can be cut or boosted by up to 15dB and the sustain can be increased or decreased by up to 24dB.
The audio signal path is exceptionally clean with a THAT 2181 used as the gain control element. High-quality input and output stages using laser-trimmed resistors have been designed to produce minimal distortion plus an exceptionally high common mode rejection (CCMR). Relays bypass the channels completely when the power is off or when the channels are bypassed, and the dynamic attack/sustain time constants respond to the dynamics of the input signal to provide a musically natural result over a wide range of input material.
