SPL Transient Designer RackPack Module – No Longer Available

Envelope modeling device with stereo link, attack, sustain and output controls
MFR# 2715

Product Description

The SPL Transient Designer RackPack Module provides a revolutionary concept for level-independent dynamic processing. In this it differs in principle from common compressors that are based upon processing signals of a specific level. Working with the Transient Designer is very simple: Attacks can be amplified or attenuated and sustain may be prolonged or shortened. However, the possibilities for studio and live application are seemingly endless.

Technical foundation is in SPL's Differential Envelope Technology (DET) which allows level-independent dynamic processing by calculating differences in generated envelopes. These envelopes are always tracking the curve of the original signal to provide optimal results in every moment of the music.

Thanks to the level-independent processing DET the setting of a threshold is needless. Other common controls of dynamic processing, such as ratio or parameters for time-constants are automated and optimized adaptively in a musical manner according to the characteristics of the input signal. Only two controls per channel are required to allow the user to completely reshape the attack and sustain characteristics of a sound: attack can be amplified or attenuated by up to 15dB while sustain can be amplified or attenuated by up to 24 dB.

A new feature of the Transient Designer module for the RackPack series is the output gain control that enables you to compensate changes in the level of the processed signal. This ensures a simple and safe adjustment of levels for any following device - especially A/D converters.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
