SPL Transient Designer 4
4-Channel Envelope Processor
The Transient Designer offers a completely new technology for level-independent shaping of the dynamic response of a sound: For the first time it is possible to control the attack and sustain behaviour of a signal in a very simple way! Unlike other dynamic devices, the processing is not goverened by the signal level but rather by its dynamic envelope, so all signals (loud and soft) are processed equally.
With no effort you can accelerate or slow down attack and prolong or shorten sustain portions of all kinds of percussive signals, such as bass drum, snares, toms, congas, etc. Let them jump into your face or flatten them with a turn of a single knob. Booming toms for example are dried up in seconds - it's almost like being able to change the amount of drum damping after the recording. Your idea of a kick drum sound is a kick drum in the words best sense? Just dial it in.
The same applies to virtually any other signal: Amplify or reduce the picking sound of an acoustic guitar, hold the sound of the strings longer, reduce the reverb time of a choir, actuate the piano pedal "electronically", turn down the slap bass a notch or give it even more attack, etc.
For stereo operation the Link function connects channel pairs (1 and 2 and/or 3 and 4). Linked channels are controlled by the same side-chain voltage so as to maintain a coherent and stable stereo image. When operating in Link-mode, the control elements of the first (or third) channel, including the Active switch, control the second (or fourth) channel, too.
Each channel is equipped with a relay hard bypass circuit to ensure a minimum signal path when the process is bypassed and to provide power fail safety. The Signal-LEDs allow to quickly monitor the signal flow, which is particularly important if the four channels are connected to a patchbay. The Transient Designer is fitted with XLR-connectors for balanced operation. To improve signal quality, SPL has developed a new hybrid-component balanced input/output stage using all laser-trimmed resistors with a tolerance of 0.01%. This approach has resulted in an exceptionally high CCMR (common mode rejection) better than -80dB at 1kHz.
