Introducing TD4 Mk2

From 2023, SPL's Mark Two variant of the Transient Designer features a new black anodised faceplate, upgraded housing and PCB and aluminium milled knobs for even better feel.

Simple Controls, Remarkable Results
Beautifully simple controls on SPL's TD4 Mk2

The Transient Designer features 4 individual channels, each with two simple potentiometers for attack and sustain. The attack knob can be adjust either to sharpen or soften transients, while the sustain knob controls the length of signal decay.

With just these two powerful controls, elements can be brought into the foreground with harsher attack and lower sustain, or blended further into the background by upping sustain and lowering attack to soften the source's transients.

A Uniquely Dynamic Power-Tool
Transient Designer 4 attack and sustain curves

Using the Transient Designer on individual sources allows control over its dynamic properties without the necessity to lean on traditional compression. This enables an elevated level of control of the transients as well as the element’s overall character.

Used in stereo linked mode, the Transient Designer can also be used as a thickening or sharpening agent for entire productions from the mix bus.
