Source Audio Atlas Compressor Pedal 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. Description Bass Optimization ModeSource Audio has 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. 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. Specs 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)
