The Atlas Compressor offers a comprehensive collection of compression circuits that perfectly capture the tone and feel of the industry’s most sought-after compressors. Straight out of the box, Atlas delivers six different styles of compression, ranging from classic stompbox compressors like the now-discontinued Diamond Optical Compressor to high-end rack units such as the snappy 1176 compressor and the smooth and gentle LA2A optical compressor. Atlas also features advanced dual-band compression, which provides an independent set of controls for both the high and low frequencies. Each compression engine has onboard controls for Threshold, Ratio, Attack, Release, Output, Tone, and Blend, allowing for fine-tuned control over the compact One Series hardware.A History Lesson in CompressionThe Atlas is packed with so many different types of compression that it could serve as a tour guide through the history of compressor equipment. First stop: classic stompbox squashers such as the legendary the Dan Armstrong Orange Squeezer and the excellent (but discontinued) Diamond Compressor. Next stop: universal and ubiquitous studio rack gear like the smooth and gentle LA2A optical compressor and the ultra-responsive 1176 FET compressor. Finally, we’re taking you to all-out nerd territory with Peak, RMS, VCA, and Dual compression, and an onboard Expander circuit… the Atlas has it all and does it well.OPTICAL RACKThe Optical Rack compressor engine is based on the legendary LA2A studio opto compressors from the early 60s. Optical compression controls its output level with light. Increasing the incoming audio level in the original units caused an electro luminescent panel to shine brighter. A photo resistor monitors that light panel and decreased the audio output level, as the panel got brighter. The result is a very smooth and gentle attack that imparts a full-bodied and natural sound on guitar, bass, or vocal. This compressor sounds great with clean strummed or arpeggiated guitar lines as well as acoustic guitars.Elite engineering cannot be rushed..."Offering up a deep library of compression options in a pedal is a landmark technical achievement. We started working on compression in 2007. At the time we developed some straightforward, high-end studio stuff that made it into the original Multiwave a year later. The research project to branch out and cover more simple classic pedal sounds and create a dedicated compression pedal was delayed, because the intricacies of how transistors behave in compression circuits was especially illusive. After ten years of additional research, new thinking, and more experience, we are finally ready to launch a landmark pedal: The Atlas Compressor. From classic rack studio units, to classic pedals of many flavors, and even to the experience of high-end computer plug-ins, Atlas covers all the bases with attention to detail that is the hallmark of our development team. Bob Chidlaw, Jesse Remignanti, and Christopher Venter worked long and hard on this one and I'm excited to finally share it with the rest of the world."Bass Optimization ModeWe have made it easy to transform the Atlas into a bass guitar specific compression machine. With the push of a button, you can convert all six of Atlas’ onboard factory presets into low-end responsive compression engines, precisely optimized for the complexities of the bass guitar. The dynamic range and attack characteristics are much different for bass than guitar. Typically, to achieve a smooth compressed bass tone, the attack and release ranges for compressors such as the 1176 FET compressor and LED optical compressors need to be dialed-in accordingly. Likewise, in dual compression modes, the cutoff frequency that separates the lower band from the higher band needs adjustments to accommodate the specific frequency range of bass guitar. It is all part of our mission to make the Atlas Compressor the most flexible and easy-to-use compression workstation on the planet.Features: 6 Types of Compression: The Atlas offers many different styles of compression with sounds inspired by studio rack gear and classic effects pedals. LA2A Optical Compression: A faithful recreation of an electro luminescent panel combined with a photo resistor and the resulting warm and smooth compression that has been the standard in studios since the 1950s. 1176 Feedback FET Compression: Based on the solid state FET compressor known for its full body and super-fast attack. LED Optical Compressor: Inspired by pedals that work on a similar concept as the LA2A, but swap the electro luminescent panel for an LED and a quicker, dirtier response. Dual Compressors: Use Atlas’ dual compressors in a variety of ways: in Series, Parallel, or Band Split mode, which provides a separate set of controls for both high and low frequencies. Studio Level Compression Controls: Access all the essential compression parameters including Feedback, Ratio, Attack, Release, Makeup Gain, Mix, and Tone, either with the pedal’s knobs or the Neuro Editor. Special Bass Mode: With the push of a button, quickly convert Atlas to a special Bass Mode with compressor engines specifically optimized for bass. Auto Makeup Gain: Dial in sounds quickly. Atlas automatically increases or decreases the Makeup Gain depending on the amount of compression.
