The TRANSIENT DESIGNER's automation is revolutionary Dynamic highly developed, so that while the processing going on inside Processor based on level- the box may be very complex, the user has to deal with just a few independent sound proces- intuitive controls.

Operation Safety Packaged in a standard 19" EIA format and occupying 1U (44,45 mm) of rack space, the TRANSIENT DESIGNER can be installed in a standard rack, but it is recommended that the rear of the case be supported, especially in touring applications. The TRANSIENT DESIGNER should not be installed near units which produce strong magnetic fields or extreme heat. Do not install the TRANSIENT DESIGNER directly above or below power amplifiers or digital processors. If possible, the TRANSIENT DES

Tech Talk In nearly every aspect the TRANSIENT DESIGNER is different from conventional Dynamic Processors or Compressors. You don't need to know how the TRANSIENT DESIGNER works in order to be able to use it effectively, but if you're at all curious as to what goes on inside the box, read this section while referring to the diagrams. Differential Envelope Technology® Differential Envelope Technology® maintains identical envelope SPL's Differential Envelope processing from quiet to loud signals (

Tech Talk Diagram 3 illustrates the shapes of the processed curves with maximum and minimum attack, compared to the original curve from Diagram 1. The SUSTAIN control circuitry The SUSTAIN control circuitry includes two further envelope generators. The envelope follower Env 3 (Diagram 4), again follows the shape of the original curve. For a longer period the envelope generator Env 4 (Diagram 4) holds the sustain level according to the peak level and the VCA control voltage is generated by the

Tech Talk Diagram 6 illustrates the processed curves with maximum and minimum sustain compared to the original curve from Diagram 1. Prevent overload Important advice when connecting to digital recording systems: Each unit connected to the TRANSIENT DESIGNER should be able to handle high input levels. With maximum ATTACK values the instantaneous input level can increase by up to +15 dB. For this reason it is recommended to connect the TRANSIENT DESIGNER to an analogue mixing console, because th

Control elements 2 1 5 3 4 1 Active The ACTIVE switch operates 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 primary or secondary side of the power supply, or when the unit is turned off at the POWER switch. If the TRANSIENT DESIGNER is operated in the LINK mode (see 5), channel one's (or three's) ACTIVE also

Control elements The ATTACK control circuitry incorporates two envelope genera- tors. One follows the original curve while the second produces an envelope with a slower attack period (Diagram 1, page 7). 3 Attack The difference (Diagram 2, page 7) between these envelopes results in a voltage that controls the VCA, boosting the transient for a period equal to the duration of the original transient. The amplitude of the attack is increased, if positive ATTACK values are set, while negative ATTACK

Applications The TRANSIENT DESIGNER is ideally suited for use in professional recording, in project or home studios and P. A. applications. For the first time the TRANSIENT DESIGNER provides the technology to manipulate the attack and sustain characteristics of a signal regardless of level, and using simple controls. Usually equalisers are used to separate instruments in a mix – the tonal aspect of the signal is considered, but not the temporal aspect. By accelerating the transients or/and short

Applications One of the most interesting applications of the TRANSIENT DESIGNER 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 Drums & Percussion increase the power and presence in the mix. The sustain period of a snare or a reverb-flag can be shortened in a very musical way to obtain more transparency in the mix. Recording a live drum set, toms or overheads can be shortened without physically damping

Applications Used to process guitar sounds, the TRANSIENT DESIGNER softens the instrument by lowering the attack. Alternatively, increasing the attack lets the sound jump to the front of the mix, which works Guitars particularly well for picking guitars. Highly distorted electric guitars are already highly compressed, leaving them with minimal dynamic range.This can obscure the note attacks, but increasing the attack setting clarifies the indi- vidual notes. High distortion also prolongs t

Power Supply Special care has gone into the design of the power supply of the TRANSIENT DESIGNER.The power supply is the heart of any electronic system, and the better it is, the better the whole system works. In an audio system, this translates into better sound quality, lower noise and lower distortion. Internal 15 VA torroidal The power supply is based around a 15 VA torroidal transformer transformer and is designed without an air gap to minimise induced hum and noise. The primary voltage ma
