Transient Designer 3 Co n t e n t s Dear customer , Thank you f or the confidence you have shown t owards SPL elec- tronics GmbH by purchasing the SPL T RANSIENT D ESIGNER , a highly innova tive D ynamic Processor manufactured to a high standard . As you would expect from an SPL unit, the T RANSIENT D ESIGNER combines exemplary technical specificat[...]

Transient Designer 4 The new T RANSIENT D ESIGNER provides a revolutionary concept for dynamic processing rendering controls such as Threshold , Ratio and Gain super fluous. T he T RANSIENT D ESIGNER 's automation is highly developed , so that while the processing going on inside the box ma y be ver y complex, the user has to deal with just a [...]

Transient Designer 5 P ack aged in a standard 19 " EIA format and occupying 1U (44,45 mm) of rack space, the T RANSIENT D ESIGNER can be installed in a standard rack, but it is recommended that the rear of the case be suppor ted , especially in touring applications. The T RANSIENT D ESIGNER should not be installed near units which produce stro[...]

Transient Designer 6 Before connecting the T RANSIENT D ESIGNER switch power off at all connected units. The T RANSIENT D ESIGNER is fitted with XLR-connectors for balanced operation. The following illustration shows the pin-wiring: T o ensure optimal signal quality , SPL has dev eloped a new hybrid- component balanced input/output stage using all [...]

Transient Designer 7 SPL's Differential Envelope T echnology® realises level- independent envelope processing , so doing away with the need for a conven- tional Threshold control. T wo envelopes are gener ated and compared - the VCA control voltage is deriv ed from their difference . Diagram1 illustrates the original curve and both generated [...]

Transient Designer 8 The SUST AIN c ontrol circuitry The SUST AIN control circuitr y includes two fur ther env elope generators. The en velope follower En v 3 (Diagram 4), again follows the shape of the original curve. F or a longer period the envelope generator En v 4 (Diagram 4) holds the sustain level according to the peak lev el and the VCA con[...]

Transient Designer 9 Diagram 6 illustrates the proc essed cur ves with maximum and minimum sustain compared to the original cur ve from Diagram 1. Impor tant advice when c onnec ting to digital recor ding systems: Each unit connected to the T RANSIENT D ESIGNER should be able to handle high input levels. With maximum A T T ACK values the instantane[...]

Transient Designer 10 The ACTIVE switch oper ates a hard-bypass relay circuit to switch the channels in and out of processing and a status LED indicates that the channel is active. The unit also switches to relay hard-bypass automatically in the case of a power failure , either on the primar y or secondar y side of the power supply , or when the un[...]

Transient Designer 11 The A T T ACK control circuitr y incorporates two en velope genera- tors. One follows the original curve while the second produces an env elope with a slow er attack period (Diagram 1, page 7). The differ ence (Diagram 2, page 7) between these en velopes results in a voltage that controls the VCA, boosting the transient for a [...]

Transient Designer 12 The T RANSIENT D ESIGNER is ideally suited for use in prof essional recording , in projec t or home studios and P . A. applications. F or the first time the T RANSIENT D ESIGNER provides the technology to manipulate the attack and sustain characteristics of a signal regardless of level, and using simple controls. Usually equal[...]

Transient Designer 13 One of the most interesting applications of the T RANSIENT D ESIGNER is processing drum and percussion sounds , both from samples to live drum sets: • The attack of a bass drum or a loop can be emphasised to increase the power and presence in the mix. • The sustain period of a snare or a reverb-flag can be shortened in a v[...]

Transient Designer 14 • Used to process guitar sounds, the T RANSIENT D ESIGNER softens the instrument by lowering the attack. Alternatively , increasing the attack lets the sound jump to the front of the mix, which works par ticularly well for picking guitars. • Highly distor ted elec tric guitars are already highly compressed, leaving them wi[...]
