P11 ABYSS Audio Compressor


P11 Abyss is a chameleon audio compressor that can go ultra clean competing against the cleanest of mastering compressors or super dirty to compete against the best of the color compressors.

Modern producers, engineers and artists should not be constrained by the need to understand different characteristics offered by the multitude of physical compressor topologies. They should not need to project and translate that information into selecting the right tool for the right purpose. One would choose VCA when seeking deep, aggressive punch; Opto for clean, open, smooth action; Vari Mu for flowing, rhythmic pulsing.

Abyss casts physically imposed rules and constraints completely aside, allowing it to masterfully exhibit any characteristic that is desired. Aggressive, punchy, smooth, open, breathy, dense, clean, dirty… it’s all here at your fingertips. Abyss fulfills the dream of having a direct connection with the audio without being mired in technicalities.

Dive in and experience the infinite colors, hues and characters Abyss beautifully draws out of your audio. It is very much designed to be equally at home on individual tracks and instruments, group buses, returns and main buses. It is designed to fulfill all mixing, stem and stereo mastering needs.

Now, more than ever – Pulsar Modular – The sound is unbelievable.

  1. This quickly became my go to compressor. It seems to sound great, no matter what the source material.
    I use it both for mixing, and mastering, colored or clean. An absolutely beautiful plugin.
    Highly recommended.

  2. Very Good Compressor, that needs time invested to better understand the inner workings.

    A special compressor

  3. I, like many, already own too many compressors, but since Climax was so good, I leaped on the Abyss. I fumbled through it during the trial, but once I figured it out, I had a powerful, versatile compressor on my hands. The presets are great places to start, and a few are spot on. Another home run!

  4. This compressor is like have many compressor inside. You can set almost everything, with so many and great sound options: saturation, eqs, knee, attack/realease manual or auto in both case, etc.

    The sound is something special, is incredible, depth and with definition. It is not like a plugin that try to clone a colour from a hardware, because the P11 have their own and beautiful colour, it is a gem in the market.

    I love this plugin, work perfect with any source, and I could clean my computer deleting so many other compressor. P11 is versatile and have a perfect sound, what more I need?

    Thanks Pulsar Modular!

  5. highly anticipated magical plugins!
