Classic Compression on Your Terms
With the IPA 25 plug-in from Pulsar Audio, you can mix and master your projects with the character of a coveted classic VCA compressor now backed by greater dynamic processing malleability than ever before. Sweetwater studio pros are loving the level of detail that the IPA 25 provides, featuring helpful and thoroughly designed controls, such as 3-stage knee engagement and Auto Makeup Gain, among others, along with a versatile toolset that includes Clipping, Limiting, Stereo Linking, and Sidechain equalization modules. Not only do you have access to this extensive parameter layout, but IPA 25 also allows you to select between four different VCA dispositions with real-time in-depth visualization built-in to perfectly match the energy of your project’s creative direction. Lastly, Pulsar Audio’s IPA 25 also promises precise, zero-latency performance while tracking, in addition to oversampling for mixing applications. The classic compressor you love, refined to enhance your mixing workflow — that’s the IPA 25 from Pulsar Audio.

Selectable compression impression
The IPA 25 conveniently allows you to work with up to four different types of compression character to adjust your gain reduction’s harmonic impression: V-Mu, IPA 25, N-Diode, and Clean VCA. V-Mu offers tube-inspired saturation that rounds over your sound and really thrives in low-mid presence. IPA 25, modeled after the original compressor’s VCA, achieves the exceptional punch and precision you know and love. N-Diode factors in a new grittiness, providing asymmetrical clipping and a more mid-forward vibe. Lastly, the Clean VCA, which, as its name suggests, is your most transparent option, is highlighted by pure envelope control. Start from scratch, utilize onboard presets, or instantly switch between vibes — with the IPA 25, you’re in total control.


Expansive tone-shaping parameters
You can expect a detailed array of parameters awaiting you aboard the IPA 25, ranging from typical hardware-based features to highly optimized modern control. To start with, you receive classic compression controls, including Threshold, Ratio, Attack, Release, and Mix, backed by helpfully detailed features like Auto Makeup Gain and variable Hard/Mid/Soft Knee engagement. Below the Compressor module is the Options module, where you’ll find compression types and Mode selections, in addition to Stereo L/R and M/S. But the refinement doesn’t end there!
Adjacent to these modules is a Sidechain section — IPA 25’s way of granting you control over how much compression you want and how to apply it. Here, you have your choice of Loud, Mid, and Norm modes to control Punch focusing, three Filtering stages, and Stereo Linking for channel-shared gain reduction. At the top of the window, a visualizer provides clear and easily adjustable Sidechain EQ monitoring. Additionally, you’ll find Clipping and Limiting modes with Ceiling settings, as well as effortless Routing for Pre-Compression, Pre-Mix, and Post-Mix assignments.
