Shape SH-1, Spectral Enhancer

$184 ($147 + VAT)

Shape HS-1 is a combination of a compressor/limiter and a dynamically dependent spectral enhancer. It works very well as a pseudo stereo device where it can do everything from subtle to extreme spectrally enhanced stereo spreading.

It can also be like an odd take of something almost like a transient designer or a very open sounding distortion.

Shape SH-1 is a eurorack module for dynamic and harmonic manipulation. It is an all analog module.

It has a compression part that produces new harmonics depending on incoming material. The transient and the tail parts of those harmonics are then separated out on separate channels so you can mix them with the clean and compressed parts in the mix section of the module. You also get all the parts out on separate outputs for further individual processing or when the Shape module is used as a mono to stereo effect.

Drive controls the amount of compression up to 10 times via 8 consecutive soft knees. The compression limits at +/-5V. Trim is for optimizing the transient part depending on the incoming material.

The module can also be used as a sort of distortion that doesn’t make the sound more dense as it distorts, it goes in the opposite direction and adds air to the sound as it distorts.

On the Aux input you can add an other signal in to the calculation engine that will be processed together with the signal in on In.

Product changes (SH-1)

Download: PRI (product change information) for SH-1 from revision R1A to R1B (pdf)

If you have a Shape module sold after May 2020 you probably have revision R1B. You can see it on the serial number sticker on the back of the front panel.

SH-1 Revision R1A to R1B

The document above describes the change of the SH-1 Shape module from revision R1A to R1B.

It also describes how to update revision R1A to R1B if you want the enhanced functionality.

Reason for change

To increase the output volume of the Tran channel and to get a wider range of the Trim knob.

The change does not affect the sonic character of the Tran channel apart from getting a wider range on Trim.

The change only affects the Tran channel.

If you need the components for this, get in touch and tell me the serial number of your Shape and I will send the components to you free of charge (valid during 2022).
