Dynamic Control That Works With Your Mix - Not Against It
Multiband compression can sometimes do more harm than good, introducing phase issues, softened transients, or uneven tone. The MLA-4 takes a different approach, giving you precise control while keeping your mix intact. You can manage low-end weight without losing punch, bring clarity to the mids without harshness, and recover depth in flattened material. It responds in a way that feels natural and predictable, so you’re not constantly correcting side effects. Each adjustment supports the music rather than fighting it, helping you move quickly and make confident decisions.
The Power of Compression and Expansion Together
This processor goes beyond standard multiband tools by combining compression and expansion across each band. You can shape dynamics in a more flexible, musical way, tightening bass while opening up the top end or restoring life to over-processed audio. With ratios available for both processes, you’re free to control and enhance at the same time. It all happens in real time, so you can hear changes as you work. Whether you’re refining balance or adding movement, it gives you a level of control that feels both detailed and easy to manage.
Sculpt Dynamics with Surgical Precision
Detailed per-band controls let you fine-tune how the MLA-4 reacts to your signal. Threshold, ratio, attack, and release are all available across each band, so you can shape lows, mids, and highs independently. This makes it straightforward to tighten the bottom end, keep midrange detail clear, and smooth out the top without overprocessing. The response stays consistent and musical, avoiding pumping or dullness. From subtle mix bus work to final mastering adjustments — you can focus on shaping the sound rather than correcting it.
Powerful sidechain for tighter dynamics
Most multiband sidechain behavior is an afterthought, either all bands react together or don’t. The MLA-4 redefines that approach with a five-mode sidechain linking system that adapts compression and expansion behavior to the material. Need full-band cohesion? Engage full linking. Want surgical control? Keep bands independent. But the real magic happens in the in-between modes, where low frequencies can shape mid and high-band compression and expansion maintaining clarity without overcorrecting dynamics. The difference is immediate: more control, fewer compromises, and a dynamic response that feels like the mix is breathing, not just reacting.
Preserve Your Sound, Perfect Your Dynamics
Balancing multiple bands can quickly lead to unwanted tonal shifts, especially when applying heavier processing. The MLA-4 avoids this with Auto Spectral Balance, which applies gain compensation across low, mid, and high bands as you work. This keeps your overall tone consistent without constant manual adjustment. You can also use Auto Level to decide whether to maintain the original balance or reshape it. The result is controlled, transparent processing that refines dynamics while keeping the character of your mix exactly where you want it.
Colouration at your fingertips
Where other multi-band processors are clean and pristine, with MLA-4, you can add harmonic excitement and colour whenever you want. Per-band THD control lets you add a subtle amount of warmth and richness to any of the three bands, meaning you could keep the highs pristine and add some depth to the low-end. No excessive saturation, no compromises!
Isolate and fix the problem
If you can’t hear the problems you’re working with, there’s no way to fix them. MLA-4 expands on the original hardware with per-band solo and left/right cut to give you a deeper insight and control over your dynamics processing. Left and right cut functions let you focus on a single channel’s contribution to the processing, making it essential for fine-tuning stereo balance. Per-band soloing allows you to isolate lows, mids, or highs to hear exactly how compression or expansion is affecting each frequency range.
The tone and power of boutique hardware inside your DAW
The MAselec MLA-4 has been at the centre of high-end mastering studios for decades. Shaping dynamics with precision and ultra-low distortion, this exclusive tool for typically reserved for elite studios and veteran engineers. Its price tag of close to £10,000 cemented its fate as hardware for the big-time players. Now, for the first time, the same uncompromising quality, control and musicality are available inside your DAW as software, without the price tag.
Built to offer the same experience and tone as the hardware, the MLA-4 delivers the same compression/expansion interplay that mastering engineers relied with the hardware, and the uncompromising sound quality as the original. Made in conjunction with the original designer and the only software to be official endorsed, the MLA-4 was made with Leif Mases to create something that’s unlike any other generic multi-band processor.
Packed with features that go beyond the original hardware, you’re getting even more value than what was previously possible. Manual gain compensation, unwanted tonal shifts and constant adjustments? All gone. The MLA-4 works seamlessly to keep your mix intact. Once you hear what it can do for your mixes, you’ll wonder how you ever worked without it!

Reviews
"The Maselec MLA-4 plug-in feels just like the real thing. The way it handles compression and expansion is effortless—no added color, just pure control. Relab doesn’t just emulate hardware; they capture what makes it special. Their plug-ins are the only ones I trust to replace the real gear." - Justin Gariano – Producer / Mixer / Engineer (Billy Joel, Toto, Reignwolf)
"This is a beast on mix buss. Ultimate fixer-upper." - Richard Chycki – Mixer / Engineer (Rush, Evanescence, Skillet, Mick Jagger, Aerosmith, Dream Theatre)
