(part of the delivery of the RackPack frame) you risk to damage the device or expose yourself to an electric shock. In these cases SPL electronics GmbH denies any responsibility. Electrical Power: Run this machine ONLY from sources which can provide proper power at the prescribed rating.

Important Security Information Lightning: Before thunderstorms or other severe weather, disconnect the machine from wall power (but to avoid life threatening lightning strikes, not during a storm). Similarly, before any severe weather, dis- connect ALL the power connections of other machines and antenna and phone/internet cables which may be interconnected so that no light- ning damage or overload results from such secondary connections.

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 SPL‘s Differential Envelope Technology (DET) which allows level-independent dynamic processing by calculating dif- ferences in generated envelopes. These envelopes are always track- ing the curve of the original signal to provide optimal results in every moment of the music.
Rear Panel/Connections XLR Sockets, Transformers, Channel Split The Transient Designer is fitted with one XLR input and two XLR out- puts for balanced operation. Pin-wiring of all XLR sockets: Pin 1 = GND, Pin 2 = hot (+), Pin 3 = cold (-) Discrete balancing stages for both in- and output provide high com- mon mode rejection and are capable of driving long cables (depend- ing on the capacity of the cables and the following input balancing...
Control Elements On, Attack With the ON button you can turn the device on or off. The ON button is illuminated when the device is active. Relay hard bypass circuits ensure signals to be directly switched from input to output in the case power failures – this “Power Fail Safety“ feature guarantees signal flow in any situation.
Control Elements Sustain, Output Gain Sustain With the SUSTAIN control you can amplify or attenuate the sustain of a signal by up to 24 dB. For more information on the operation of the SUSTAIN control please refer to “Technology“ on page 20 cont. The SUSTAIN control circuitry also uses two envelope generators.
Control Elements Link Mode Link Mode You can operate two Transient Designer modules at a time by activat- ing the LINK mode. You can only run two modules in the LINK mode at a time. Main applications may be stereo processings. Another interest- ing example is the transfer of a rhythmical pattern or structure from one channel to another (see “The Transfer Of Dynamic Structures”...
Control Elements Signal LED, Overload LED Since the modules are configured as master or slave with the dip switches on the circuit board, you have to decide upon their placement within the RackPack before you install them. It is customary that the left module serves as master and the right module serves as the slave.
Applications Drums & Percussions The Transient Designer is ideally suited for use in professional record- ing, in project or home studios and sound reinforcement applications. For the first time you can manipulate and control the attack and sus- tain characteristics of a signal regardless of level in the most intuitive and simple way.
Applications Drums: Ambience • The Transient Designer is a perfect alternative to noise gates in live drum miking. Adaptively reacting to the duration of the origi- nal signal, the sustain is shortened more musically than with fixed release times and a drumset is freed from any crosstalk quickly and effectively.
Applications Guitars, The Transfer of Dynamic Structures Guitars Use the Transient Designer on guitars to soften the sound by lower- ing the ATTACK. Increase ATTACK for in-the-face sounds, which is very useful and works particularly well for picking guitars. Or blow life and juice into quietly played guitar parts.
Applications Bass, The Re-Invention of Reverb Bass: Staccato vs. Legato Speaking of bass: Imagine a too sluggishly played bass track ... you may not have to re-record it: Reduce the SUSTAIN until you can hear clear gaps between the downbeats—the legato will turn into a nice staccato, driving the rhythm-section forward.
Applications Backings, Keyboards & Sampler, Post Prod., Mastering Backings A common problem especially with tracks that are recorded and mixed in different studios: Backings lack of ambience, and finding a reverb that “matches” takes time ... so simply emphasize the original ambi- ence by turning up the Transient Designer’s SUSTAIN control.
Differential Envelope Technology (DET) SPL‘s DET is capable of level-independent envelope processing and thus makes any threshold settings unnecessary. Two envelopes are generated and then compared. From the difference of both envelopes the VCA control voltage is derived.
Technology Attack Control Circuitry, Sustain Control Circuitry Diagram 2: Calculated Control Voltage (Attack) U/mV Difference Env 1-Env 2 (Equals VCA Control Voltage) t/ms Diagram 2 shows the difference between Env 1 and Env 2 that defines the control voltage of the VCA. The shaded area marks the difference between Env 1 and Env 2 that controls the control voltage of the VCA.

Option Lundahl I/O Transformers As an option, the Transient Designer RackPack module can be fit- ted with input and output transformers from Lundahl. The transfor- mer options can only be ordered by purchase, a later upgrade is not possible. Information On Lundahl I/O Transformers Transformers have a pleasant sound characteristic, especially the low end sounds rounder and more full-bodied.
