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. Amazing tools.
    Great sound quality.

  2. Sounds like hardware I used to use in studios

  3. This was my entry into the Pulsar Modular catalog. Being just a hobbyist/ singer songwriter, I still saved up to get the P11, seeing the potential in it for myself, against all the talk about it being just another expensive compressor. That took me almost a year as it is definitely not a small amount to come up with.

    It is a difficult compressor plugin to learn. I found it very challenging and yet, I also found it to be absolutely rewarding. It is very versatile and it is possible to shape, or should I say achieve the sound that you have in your mind, by simple tweaking the parameters in the plugin. Discovering which parameters to tweak, is the journey that this plugin will take you on.

    Is it worth it? I reckon you have to decide that for yourself. There’s a good demo period. Do I recommend it? Yes, but only if you’re willing to spend some time with it, to learn all the controls and figure out what it can do. It surely works as a normal compressor, but if that’s all that you want, you’re paying way too much for it.

    This is a mainstay on my vocal bus, my guitar bus and my drum bus. I only do not have it on my 2bus as that’s where I have the new MDN Sidecar. ????

  4. Sounds like hardware.
    Very nice.

  5. “All of Pulsar Modular’s plug-ins are just absolutely incredible. I’ve replaced so many plug-ins today while testing against plug-ins I’ve used for years; all lost their job today LOL. P42>ABYSS>P44 ( with clipper engaged) will give any mix bus a run for its money” – Alex Elliott
