Tierra Audio Boreal FET Compressor

Mono analog compressor

Boreal FET Compressor TAKE 2 is the new analog version of our fast FET Compressor.
The perfect control for your sound with the characteristic color of TIERRA Audio.
Boreal FET Compressor has been designed to provide your sound with a high dynamic control, optimal for the most state-of-the-art professional recordings.

Voices “In-Your-FACE”

Step 1: Insert a Boreal FET Compressor in your voice track.
Step 2: Play around with a slow ATTACK, quick RELEASE, and RATIO 4.
Step 3: Gradually increase the INPUT control. You will see how the voice compresses until it reaches the forefront of your mix. All without shredding its character.

Piano management

After a grand piano recording session, it may happen that some section dynamics are so high that you must turn them down in the mix… While others are so low that you cannot hear them, isn’t it?
Boreal FET Compressor will be your best ally in these scenarios. Boreal allows you to handle the most complex dynamics in the most challenging situations.

Overwhelming basses

Boreal FET Compressor is the perfect tool to insert your bassline. It will balance your basses bringing a unique robustness to your mix.
Thanks to Boreal FET Compressor you will be able to work with high gain reductions through transparent pumping.

Handmade with love in Madrid
In order to guarantee the correct electron flux of the analog signal, we put together the finest “through hole” components, instead of robotically assembled miniaturized components. In this way we reduce to the minimum the electronic friction to enhance the thermal response of the equipment and avoid background noises.

Triad Magnetics® and Lundahl® transformers
Every Boreal FET Compressor is equipped with two transformers:
an original Triad Magnetics® transformer to nurture the power stage, and a Lundhal® transformer for the input stage, thus providing a more stable, precise, and lasting result, that does not generate any type of noise.

VU meters
Each Boreal FET Compressor also contains one excellent VU meter so that you can accurately control the gain levels of the analog signal.

Gold plated connectors
When speaking about true ProAudio, all the links of the recording chain are fundamental. Gold plated connectors guarantee the best connectivity, and a total absence of contact noise as well. A real piece of jewelry in your hands.

Made of pure cherry wood
A picture is worth a thousand words. So, we wanted to ensure that you will know that your Boreal FET Compressor has the makings of a champion only by looking at it. Finished with a warm and resistant natural cherry wood paneling, from sustainable forests, we ensure better thermal insulation and surprising aesthetics. Technology and art in a superb symbiosis.

Light and robust
By building our products in aluminum, we ensure the highest durability, lightness, corrosion resistance, and thermal insulation. Besides all this, aluminum is an easily recyclable metal that always retains its properties, avoiding indiscriminate exploitation. Makes sense, doesn’t it?

Cardboard packaging
The cardboard packaging in which we ship our equipment comes from recycled sources and is FSC certified. They are light and resistant, protecting the equipment from impacts during transport, thanks to the air chamber system that keeps the equipment in suspension. With this change, we use fewer raw materials and resources, and we can source locally. You can take it everywhere with you thanks to its handle, keep it to store your equipment, or recycle it.

Branded by fire
We want you to use your Boreal FET Compressor intensively for decades. That is the reason why the frontal and back panels are laser engraved, avoiding deletion or damage of the screen printing over metal or wood, through time.

Certified Authenticity and Quality
With your Boreal FET Compressor, you will get a Certificate of Authenticity and Quality, sealed and signed by hand, that contains the results of the technical measurements conducted over the equipment during our extensive quality control. Thoroughness, transparency, and a 5-years warranty.

One device, one tree
Not only do we create the best products, but we also care about the environment. Therefore, we commit ourselves to plant a tree in exchange for each sold device. You may visit it whenever you want!
