Manufacturer's ID: ATLAS

What we say:

At A Glance:

The Source Audio Atlas Compressor is a unique pedal that offers six digital models of legendary rackmount and stompbox compressors. If you're looking for a specific compressor sound, you'll find it here, where you'll be able to quickly switch between pristine studio compression and vintage optical compression, or run even both at the same time for a stunning sound that's full of character.

Features We Love:

Legacy Compression

The Atlas comes pre-loaded with beautifully realistic models of six of the most iconic compressors of all time. Compressor models include the classic rack-mounted 1176 limiting amplifier and the LA2A optical compressor, plus the Dan Armstrong Orange Squeezer and awesome Diamond Compressor stompoxes. This gives you a powerful selection of compression options that each have their own distinctive character.

Bass Mode

Holding the control button down as you power on the pedal shifts it into bass mode. This optimises each of the compression models for bass guitar, allowing you to achieve precision compression without unwanted distortion.

Neuro Editor Software

While the pedal itself features an intuitive 4 knob operation, tone chasers will absolutely love connecting the pedal to the Neuro Editor software or app. This explodes each preset out to give you a level of control unseen on other compression pedals, including unique features like Look Ahead, Graphic EQ, Dual Compression signal routing and Side Chain High and Low Pass Signal Detection controls. If you're looking for a nuanced style of compression, you'll find it here.

Who Is It For?

Players who need a refined selection of compression options


  • Pristine models of some of the finest compressors
  • Bass mode optimises the pedal for lower frequencies
  • The free software offers an unprecedented level of control
  • Can be run in mono or stereo


  • Pedal 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.
  • Pedal Specification
    • Includes 9v DC power supply (300mA / Negative Tip)
    • Includes 1/8” to 1/4” cable for Neuro Mobile App connection.
    • Power Consumption — 165mA
    • USB port — Connects to Mac or Windows PC for firmware updates and the forthcoming in-depth effects editing software.
    • Brushed anodized aluminum housing.
    • Dimensions: L: 4.5 in./11.4cm x W: 2.75 in./7cm x H: 2 in./5.1cm (including knobs)
  • Neuro Editor Features
    • Connect the Atlas Compressor to the Neuro Desktop Editor (a free download for Mac or Windows computers) or the Neuro Mobile App (free for iPhone and Android) and explore the power of effect downloading, customization, and sharing that comes with every One Series pedal.
    • Growing Library of Published Presets: Quickly test and download sounds from the ever-expanding collection of published User Presets created by Source Audio and the rest of the Atlas Compressor/Neuro Editor Community.
    • Deep Effects Editing Capabilities: Use the Neuro Desktop Editor (free download for Mac and Windows) or the Neuro Mobile App (free for iOS and Android) to create, store, and share highly customized filter effects.
    • Dual Compressor: 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.
    • ​Dan Armstrong Orange Squeezer: A gritty compression inspired by the vintage 1970s unit that graced classic tracks like Steely Dan’s “Peg” and Dire Straits’ “Sultans of Swing.” Available in the Neuro Editor.
    • Look Ahead Compression: A classic studio trick. When engaged, Look Ahead creates an imperceptible latency in the signal that “looks into the future” and allows for an extra quick and smooth attack that without any additional distortion or artifacts.
    • Soft Knee:Adjusts the transition curve of the Threshold point. A sharper knee creates a snappy compression and a soft knee creates a more natural sounding compression.
    • Side Chain Compression: Use the signal going to Input 2 to trigger the compression applied to the signal going into Input 1.
    • Advanced Equalization: Use the 3-band parametric or 8-band graphic equalizers to tweak the tonal characteristics of your compression.
    • USB Connection – Use the pedal’s mini USB port to connect Atlas to the Neuro Desktop Editor, which can be used to edit presets or download the latest pedal firmware.
  • MIDI Features
    • The Atlas Compressor responds to MIDI Program Change (PC) and Continuous Controller (CC) messages via its mini USB port. The USB port handles communication between the Atlas and digital audio workstations (DAW) on Mac and Windows machines as well as external MIDI controllers with USB host support (we recommend the DMC.micro from Disaster Area Designs)
    • Preset Saving – Save up to 128 effect presets.
    • MIDI Mapping – Use the Neuro Desktop Editor to easily map MIDI Continuous Controller (CC) messages to a comprehensive list of parameters.
    • Preset Recall - Use MIDI CC numbers 103 & 104 to recall any of the Spectrum's 128 MIDI accessible presets.
    • The Neuro Hub - Connect the Spectrum to the Neuro Hub and use MIDI CC messages to control parameters or recall presets.
    • Note: As of Hub fw 1.18 and Spectrum fw 1.05, the Spectrum can now be added to scenes, is visible through the Hub, and can be controlled by PC messages, giving you the full access to 128 preset slots.
