The SPL DeEsser Mk2 offers two mono DeEssers in one 19" unit - surgically removing undesired sibilant frequencies in a simple and musical way, cancelling out S-sounds without affecting the natural character or timbre of the voice.

The SPL DeEsser Mk2 is a redesigned and upgraded version of the original DeEsser featuring the same processing qualities as its predecessor, but in a new design and has an even better feel due to the solid aluminum knobs. The DeEsser Mk2 offers two mono DeEssers in one 19" device.

SPL DeEssers are well known for removing undesired sibilant frequencies in a simple and musical way by cancelling out S-sounds without affecting the natural character or timbre of the voice since 1996.

In opposite to traditional DeEssers the SPL DeEssers are not based on compressor-technology. The SPL DeEssers are Auto-Dynamic DeEssers. They use a circuit technology that automatically adjusts to the S-frequencies and narrows the bandwidth so that only the range of the S-sound is processed and all neighboring frequencies remain untouched. The frequency band determined in this way is mixed back to the original signal in phase-inverted form, whereby the S-sound is acoustically removed. The result is a sound-neutral, unobtrusive, but extremely effective way of working. In addition, time-consuming readjustment of the frequency settings is no longer necessary.

The SPL DeEsser Mk2 combines sound neutrality and efficiency with premium look and feel.

Auto-Dynamic DeEsser – the revolution of S-sound reduction.

The DeEsser uses a unique technology to reduce sibiliance in a mix or on vocal tracks. It automatically detects and hones in on the sibilant frequencies leaving neighboring frequencies unaffected. These S‑sounds are mixed back into the main signal phase-inverted to cancel out the sibilance. The result is a sound-neutral, inconspicuous and extremely effective process. Even at high S‑Reduction values the de-essing has an egligible effect on the character and timbre of the voice.

The Auto-Dynamic DeEsser has a new circuit technology that automatically adjusts to the S‑frequencies and narrows the bandwidth so that only the range of the S‑sound is processed and all neighboring frequencies remain untouched. The frequency band determined in this way is mixed back to the original signal in phase-inverted form, whereby the S‑sound is acoustically removed. The result is a sound-neutral, unobtrusive, but extremely effective way of working. De‑essing now has very little negative influence on the timbre of the voice; side effects such as twanging or lisping do not occur. In addition, time-consuming readjustment of the frequency settings is no longer necessary. The SPL Auto-Dynamic DeEsser combines efficiency with sound neutrality. By the way, you can also soften hard cymbal sounds or snares perfectly with the DeEsser Mk2.

Inputs and outputs

The two channels of the De-Esser are equipped with Neutrik XLR sockets with gold-plated contacts. The signal transmission is electronically balanced at a nominal level of +6 dB.

Looks great, feels great – and lasts for a lifetime

The DeEsser Mk2 has a 4 mm thick, black anodized aluminum front panel and aluminum knobs milled from solid. The housing is made of high-quality steel and is powder-coated in elegant black.

Sounds good

All SPL devices are developed not only according to plan, but also by ear. Many important components are installed on the circuit boards using Through-hole technology. This way SPL can ensure they use the best sounding components.
