Source Audio Spectrum Intelligent Filter

Since Source Audio recently released a synth pedal, it seems appropriate for them to follow it up with a filter one, since filters are an unmissable component in synthesizers… Enter Spectrum, which will make history also for being the first Source Audio pedal ever with non-descriptive graphics!

Sporting the usual 3-way toggle switch and four knobs shared by all Source Audio’s compact models, the Spectrum is a stereo stompbox with external expression and tap tempo control that offers three modes inspired by classic filter pedals of the past like the Mu-Tron and the Lovetone Meatball, with 8 settings editable directly from the pedal (thanks to alternate functions accessible by pressing the alt button) and many more accessible via MIDI and through the Neuro editing app, available both for iOS and Android.

As you can imagine, this circuits delivers either attack-driven envelop filter (Tron and Dumpling modes) or autowah (Thrust mode).

Neuro gives you access to additional filter, octave, and distortion blocks to create highly unique effects. In the app you’ll also find space for 128 presets (you can store 6 on the pedal) and a growing library of tones.

The Spectrum Intelligent Filter is the most powerful stereo filter effect pedal ever created. Building on almost 15 years of filter pedal technology and know-how, Spectrum is the culmination of our finest envelope sounds and best thinking on how to easily incorporate those sounds into rigs of all types. The pedal not only features finely crafted envelope filter effects inspired by some of the most iconic and sought-after effects pedals on the market, it also includes buzzing, synth-like octave and distortion effects. The pedal is a cleverly integrated, all-in-one jam/funk machine. Whether you want to easily plug and play with its six carefully crafted factory sounds, browse the ever-growing Neuro library for additional sounds created by Source Audio and other Spectrum owners, or use the Neuro’s deep sound editing tools to create your own presets, this filter pedal will satisfy the needs of any bass or guitar player.

Plug In and Play

The Spectrum Intelligent Filter was designed with special attention given to the simple plug-and-play experience. Right out of the box the Spectrum offers easy access to tones inspired by some of the most iconic and difficult to find envelope filters effects pedals on the market. It also offers synth-like tones comprised of distorted octave and envelope phaser sounds. Because of the pedal’s ALT button, the Spectrum’s four knob control surface actually offers access to eight different parameters. Use the Spectrum’s Input Gain, Sensitivity and Speed controls to dial in the perfect envelope response for your needs. Maybe you like a slow and smooth envelope movement while you really dig-in on the strings, or possibly you want a quick moving filter that responds to light picking – either way is achievable with the Spectrum.? The Frequency, Resonance, Depth and Mix controls provide fine control over the color and character of your filter effects. Whatever your needs, the Spectrum is the most comprehensive filter effects pedal available.
The Neuro Editing Systems
On the surface, the Spectrum Intelligent Filter features a simple 4-knob interface and a choice of six amazing guitar/bass envelope filter effects – just plug-in and play. If you want to take things to take things a bit further, we urge that you connect the Spectrum to our Neuro Preset Editing & Browsing tools. The Neuro Mobile App is available for free at the App Store (iOS) and Google Play (Android). The Neuro Desktop Editor is available as a free download for Mac or Windows systems on our Downloads page. Inside Neuro you will find the tools to create your own one-of-a-kind envelope tone. Use the Spectrum’s collection of two parallel filter voices, octave up or down effects, and distortion to dial in that perfect tone. The Neuro also offers a growing collection of additional envelope filter presets created by the Source Audio team as well as the ever-expanding community of Spectrum users – just touch the screen to open a preset in your Spectrum. If you like what you hear, hit the BURN button and upload the preset to any of the pedal’s six toggle switch positions.
