Limiter channel linking: linked vs unlinked, and keeping lows linked

Channel linking: yes or no?

Simply put, it decides whether the left and right channels are processed together or separately.

The example

Imagine a loud sound only appears on the left side of your mix.

• If your limiter is fully linked, both channels react together.
• If your limiter is unlinked, each side reacts independently.

Sounds simple. But the consequences can be huge.

Why link the channels

Linking preserves the stereo image and keeps the phantom center exactly where it should be. That matters most when you have a lot of elements spread across the stereo field.

• More stable imaging
• Less unwanted pumping
• A more natural sounding master
• Your center stays centered

Why unlink them

Unlinked, the limiter applies different gain reduction to each side, which generates additional side information. The song can suddenly feel:

• Wider
• Bigger
• More dynamic
• More exciting

And sometimes that is exactly what the song needs.

There is a catch. On electronic music, hip-hop, pop, urban, EDM, or anything where the low end matters a lot, letting the lows move unsynced between left and right costs you punch, energy and impact.

The fix: Tone Projects Uni-L

There is a limiter that solves this. Lately I have been using Tone Projects’ Uni-L a lot. Honestly, it is probably the most versatile and customizable limiter I have ever used.

Linked Lows

It lives inside the Channel Linking section, and it keeps the low frequencies linked together no matter what the rest of the linking settings are doing.

So the low end stays 100% linked while you experiment with different linking values for the transients and the body.

Instead of being locked into someone else’s idea of where the lows should sit, I adapt it to each song individually:

• More control
• More flexibility
• More consistency

It has let me get channel linking right in pretty much every situation I have run into so far.

Channel linking isn’t right or wrong. It’s a creative decision. The trick is knowing what you gain, and what you sacrifice.

Final thought

Linked Lows has become a secret weapon for me, because it keeps the foundation solid while I still explore everything channel unlinking has to offer.

Enjoy experimenting with it. Just don’t destroy your sub in the process.
