SPL has announced the Model 1503 DeS Dual Band De-Esser (its original Model 9629 Auto Dynamic de-Esser presented as a single-slot 500-Series module) and Model 1502 TDx Transient Designer (the Model 9842 Transient Designer also as a single-slot 500-Series module).
Unlike traditional compression techniques, the process used by the original designs was intended to be unobtrusive and to simplify controlling the processing intensity to a single (S-Reduction) parameter. The Model 9629 readily established itself with recording studios and broadcast stations, as well as in the live sound engineering community. In 2007 SPL introduced the Model 1070 Dual Band De-Esser module for its proprietary RackPack modular system, expanding on the original concept by making use of two frequency bands – High S-Reduction and Low S-Reduction – that can be used independently or jointly to increase processing effectiveness without introducing audible artefacts.
This technology is also available in the all-new Model 1503 DeS Dual Band De-Esser 500-Series module.
In 1998 SPL showcased Differential Envelope Technology (DET), which allows for level-independent dynamic processing by calculating differences in generated envelopes. These envelopes track the curve of the original signal to provide optimal results in every moment. The first product to make use of this technological breakthrough was the Model 9842 Transient Designer. Like the Model 9629 Auto Dynamic De-Esser before it, the 19-inch, 1U Model 9842 Transient Designer is simple in use – using the attack controls, attacks can be amplified or attenuated and, using the sustain controls, sustains can be lengthened or shortened. Only two such controls per channel are required to allow the user to totally reshape the attack and sustain characteristics of any sound. This appeared in the proprietary RackPack system in 2007 as the Model 2715 Transient Designer, with an added output gain gain control.
The new Model 1502 TDx Transient Designer adds a Mix (parallel mix) control, allowing continuous blending of the processed (wet) and unprocessed (dry) signal, so functionality is extended further with three parameters – attack, sustain, and mix, each offering intuitive operation while combining to increase options for designing transients to suit a greater variety of programme material.
The Model 1503 DeS Dual Band De-Esser and Model 1502 TDx Transient Designer boast a 10Hz to 100kHz frequency response and 116dB dynamic range.
