Elysia nvelope

The nvelope offers significantly enhanced sonic capabilities and flexibility. Unlike its predecessor, which was originally developed by our CEO Ruben Tilgner when he worked at SPL, the nvelope allows for precise control over attack and sustain parameters within specific frequency ranges, thanks to its Dual Band mode. This selective processing leads to a more natural, musical response, minimizing unwanted artifacts often encountered in Full Range mode. The improved sound quality, combined with its advanced features, makes the nvelope not just a transient shaper but a powerful tool for detailed dynamic sculpting, delivering superior clarity and punch.

Full Range Mode
nvelope operates independently of the specific level of a signal, and you do not have to spend a lot of time trying to balance a set of complex controls to quickly get the results you seek.

Dual Band Mode
The attack and sustain parameters become much more flexible by selectively processing a certain frequency range chosen by the user.
The Freq A controller now sets the start frequency for attack processing, while the Freq S controller determines the end frequency for sustain processing. The function of the Attack and Sustain controllers remains the same as in Full Range mode.

EQ Mode
A very nice side effect of the topology of nvelope is that it can also be used as a shelving filter. This is achieved by temporarily deactivating its dynamics sections while keeping the filter stages active.

Freq A now sets the frequency of the high shelf filter, while Attack determines the amount of cut (turn left) or boost (turn right) in this band. Similarly, Freq S sets the frequency of the low shelf filter and Sustain determines the amount of cut or boost.

The two channels be used as two separate equalizers at the same time, or be linked together for processing stereo material as well.

Mixed Mode
nvelope has two channels of Full Range or Dual Band impulse shaper or shelving EQ, which can be operated stereo linked or dual mono.
But, the two separate channels can also be used for different tasks at the same time. For example, you can shape one signal in Dual Band mode in channel L and a completely different signal in Full Range mode in channel R.
Or, you can connect the output of channel L to the input of channel R, and then process the frequency response of one single signal with the EQ first, followed by some nice Dual Band impulse shaping.
There are lots of possible combinations.

Auto Gain
Boosting the attack in Full Range mode can sometimes result in some pretty huge level peaks. These can make your processed signal sound uneven, and in the worst case they will create the nasty kind of distortion you don’t want.

nvelope solves this with the Auto Gain function. This simple button makes the impulse shaper automatically compensate stronger level peaks, so this can be the solution for many level-related issues caused by the attack processing.

US and EU parcels ship via UPS, ETA 1-7 working days from pickup day zero. That also applies to most locations worldwide.

All shipments are fully insured.

Bigger shipments requiring pallets or custom made crates ship to US, CA, JP, CN, AU and other outside of EU locations via DHL Air Freight, ETA is normally approx. 7-14 working days from pickup day zero.

Big shipments inside EU ship via different freight companies, recently mostly via ACE Logistics. Freight forwarders can use different courier companies for deliveries to final destinations.

Palletising and crating time can vary depending on the size of the shipment and packaging queue. We pack all our shipments with great care.
