Waves Kramer HLS Channel

What is Waves Kramer HLS Channel Used For?

Waves Kramer HLS Channel is a channel strip plugin designed to bring the color of an iconic Helios console, made famous by legendary recordings notably made in London. Used in mixing on individual tracks (vocals, guitars, drums), on buses (drums bus, guitars, backing vocals), or even on the master, it has a clear goal: to immediately add a "record" feel through bright equalization and organic saturation.

Its value is especially strong in rock, pop, indie, funk, and blues productions, but also whenever a project lacks definition: a bass that is too timid, a guitar that doesn't cut through, a vocal that needs air, or a drum bus that needs to become more solid without being crushed. With just a few adjustments, HLS Channel helps achieve a more present, denser, and more coherent sound while maintaining a typically analog musicality.

Main Features

A faithful modeling of an "authentic" Helios console

Many original Helios modules have been modified over time. Here, the approach is to reproduce the behavior of a reference considered representative of the sought-after sound, to recover the signature that marked so many classic recordings. The result is not a simple "clinical" EQ: it is a dynamic response and coloration that is felt as soon as you start boosting gains.

The Helios equalizer: fast, inspiring, and extremely effective

The heart of Waves Kramer HLS Channel is an EQ with a strong character, designed to enhance a source with minimal hesitation. The frequencies offered and the boost/cut choices are deliberately musical: the focus is on the essentials, quickly finding the spot where the sound opens up, comes forward, or sits in the mix. It's the ideal tool when you want to work by feel rather than with an overly "surgical" approach.

A sculpted midrange to bring out the instrument

The midrange is often the decisive area: it's where the guitar finds its place, the voice gains intelligibility, and the piano stops fighting with the rest. HLS Channel offers 8 carefully chosen center frequencies, with gain adjustment and boost/cut options, for very effective tonal shaping. In practice, you can thicken a snare, tame vocal nasality, or add attack to a guitar without making it harsh.

A "fat" and controlled low end, including for vinyl constraints

The low end is treated with a simple and very useful logic in production: several boost points in the bass allow reinforcing the foundation (for example on bass and kick) without making the mix muddy. Conversely, a dedicated cut in the extreme lows helps clean up sub-bass and control unnecessary energy, which becomes particularly relevant in certain mastering contexts, especially when monitoring the low end for specific formats.

Air and presence in the highs, without harshness

When a mix lacks definition, a well-chosen high-frequency boost can transform the whole. HLS Channel allows working this area to add air, clarity, and brightness, with a curve known for its smoothness. On vocals, this helps gain articulation; on overheads, to reveal shimmer; on an acoustic guitar, to recover playing details. And if a source is too bright, the high section also allows taming excess.

Preamp and saturation: texture, not just volume

Beyond the EQ, the plugin models the drive of mic/line preamps. This is where you get that extra soul: slight harmonic compression, density that brings the source closer, and a "grain" that helps glue elements together. Subtly dosed, it's perfect for adding energy without radically changing the balance; pushed further, you get more obvious saturation, highly appreciated on buses or solo instruments.

Analog noise and 50/60 Hz hum: vintage realism on demand

For those seeking a decidedly vintage aesthetic, HLS Channel offers the optional addition of analog noise and historically accurate 50/60 Hz hum. You can enable them to recreate a "console" feel or disable them to keep all the color of the processing without noise, ideal in modern productions with high dynamics.
