How to use two compressors on vocals.
Raw vocal recordings can be uneven, thin, or harsh — making it difficult to get them to sit in the mix. One of the most trusted techniques used by pro engineers and producers involves using two compressors in series.
Both the UA 1176 Classic Limiter Collection and the Teletronix® LA-2A Leveler Collection are a perfect combination to smooth things out. This method has been used for decades, thanks to its ability to preserve nuances while delivering punchy, professional sound.
Let’s explore how this duo can transform your vocal recordings, and how you can use it in your own mix.
The LA-2A Silver, LA-2A Gray, and LA-2 models offer distinct variations in control and sound — from compression and headroom settings to unique clipping characteristics.
The UA 1176 Classic Limiter Collection provides three distinct 1176 revisions, together representing over 40 years of design iterations.
Why Use Two Compressors?
Using an 1176 and LA-2A together gives you the best of both worlds — fast peak reduction from the 1176 and smooth, natural leveling from the LA-2A. This technique is widely used in professional studios for these reasons:
- Tames loud transients with the fast attack of the 1176
- Smooths dynamic range with the gentle compression of the LA-2A
- Enhances tone and warmth using the rich analog character of both units
- Creates a controlled yet natural sound that stays present in the mix
This setup is most commonly used on vocals, but you can also apply it to bass, guitars, drums, and more.
Pro Tip: Try experimenting with different models of the LA-2A and 1176 to find the one that best suits your voice.
How to Use Two Compressors
Step 1: Control Peaks with the 1176
If you have a raw vocal track that jumps in volume at certain moments, making it difficult to keep balanced in your session, the 1176 is your first line of defense.
How to set the 1176 plug-in:
- Set a fast attack and fast release to grab peaks quickly.
- Adjust the input to trigger gain reduction only on the loudest parts.
- Choose a 4:1 or 8:1 ratio for smooth but noticeable compression.
With these settings, the vocal transients are controlled, making it easier to blend into the mix without losing energy.
The 1176 Rev A “Blue Stripe” 1176 is known for its aggressive yet musical character.
Step 2: Smooth Out Your Performance with the LA-2A
With the 1176 handling the large transients, the LA-2A takes over to smooth out the overall performance.
How to set the LA-2A plug-in:
- Set the Peak Reduction knob to compress the vocal.
- Use the Gain control to match levels.
- Adjust the Emphasis control to prevent over-compressing low frequencies.
- Notice how the LA-2A Silver adds tube warmth and body to your vocal.
With its brushed aluminum panel and original T4B gain reduction module, the cherished late-’60s “Silver” LA-2A is perhaps the most flexible of the three versions included in the UAD plug-in collection.
Final Thoughts
The 1176 and LA-2A vocal chain is a classic for a reason — it balances dynamic range while enhancing tone and presence. Beyond vocals, this pairing works great on bass, drums, electric guitars, and more.
