Source Audio Atlas Multi Compressor Pedal

The Source Audio Atlas Multi Compressor offers a comprehensive collection of compression circuits. They 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.

Additionally, 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 Compression

The Atlas offers many different types of compression that it could be a tour guide through the history of compressors.

First stop: classic stompbox squashers such as the legendary Dan Armstrong Orange Squeezer and the excellent (but discontinued) Diamond Compressor.

Next stop: universal and ubiquitous studio rack gear like the gentle LA2A compressor and the ultra-responsive 1176 FET compressor.

Finally, we’re taking you to all-out nerd territory with Peak, RMS, VCA, Dual compression, and an onboard Expander circuit… the Atlas has it all and does it well.

Optical Rack

The 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 photoresistor 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, natural sound on guitar, bass, or vocal. This compressor sounds great with clean strummed or arpeggiated guitar lines as well as acoustic guitars.

Atlas with STUDIO 76

The Studio 76 compressor is based on the 1176 studio rack compressors of the late 60s and early 70s. This solid-state FET compressor is known for its full body and super-fast attack. All of the attack times in 1176 compressors clock in at less than a millisecond. Studio 76 is a great compressor for fast and aggressive country pickin’ (think Johnny Hiland)

Cubic Zirconia

The Cubic Zirconia was inspired by Opto compressors that use; an LED in place of the LA2A’s electro luminescent panel.

This technology is usually what you find inside effects pedals. Using an LED as an optical compressor’s light source creates faster attack and release times. This generate artifacts that tend to make the compression sound dirtier. This is a great sound for playing both tight and funky riffs on the guitar.

Studio Snap

A very aggressive and modern-sounding compressor. It’s based on a hard-knee, VCA feed-forward type compressor. It uses two compressors in parallel to handle both RMS level controls (“Root Mean Square” compression means that the compressor will react according to the “average loudness”) AND the peaks.

The combination of these two compression approaches gives STUDIO SNAP its character.

Dual-Band

The Atlas has two independent compressors. You can route them in a number of different ways. They can run in Series Mode (one running into another).

They can also run in Parallel Mode and be mixed together with a Crossfade control. The Dual-Band compressor runs in Band Split Mode, which is a version of parallel routing where one compressor controls only the higher frequencies (everything above 333Hz) and the other controls the lower frequencies (everything below 333Hz).

With the Dual Band Compressor, the high frequencies release faster than the lower frequencies, so as you sustain a chord the low frequencies remain compressed while the second compressor releases the high frequencies. The result is a beautiful blooming effect that accentuates high harmonics. This is a great compressor for slow ringing chords or lead lines with long sustained notes.

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. 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 flavours, and even to the experience of high-end computer plug-ins, Atlas covers all the bases with attention to detail which 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.”

Atlas 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 photoresistor 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 optimised for bass.
  • Auto Makeup Gain: Dial-in sounds quickly. Atlas automatically increases or decreases the Makeup Gain depending on the amount of compression.
