A Revived Spectacle of 10-band Analog Processing

Unveiled exclusively for Moogfest 2019’s engineer pass holders, the Moog Spectravox emerged as a beacon of 10-band spectral vocoder processing among several discerning synthesists at Sweetwater. To their surprise, its updated form and functionality are finally ready to integrate into any synthesis rig, bearing Moog’s classic fat analog character with a collection of iconic and versatile parameter controls. It all starts with an onboard VCO, spectral shift controls, and expansive program input options, allowing the Spectravox to yield a vast array of sound possibilities, from shaped ambient drones to unique vocoder patches and beyond. Likewise, a 3.5mm patchbay introduces a seamless path to several internal and external sound controls, along with a 1/4-inch XLR combo input for microphone, instrument, and additional sound source processing. Complete with an included 12V power supply and pro-designed preset overlays from the patching experts at Moog, Spectravox has never been more ready to apply exclusive audio processing to nearly any instrument foundation in the books.

10 bands of elite sonic experimentation

Beginning with the processor's onboard VCO and 1/4-inch XLR combo input, the heart of the Moog Spectravox lies within its 10-band filter bank, skyrocketing sonic capabilities from simple signal tuning to complex modulated filtering schemes and everywhere in between. Combined with front-panel spectral shift, VCO, and envelope controls, manufacturing colorful spectral drones, personalized vocoder voices, and atmospheric sweeps is straightforward, with more than enough wiggle room for extra audial experimentation. Topped off with a built-in envelope generator and expanded rig compatibility, the Spectravox is more than just a spectral processor — it's a standalone synth, CV filter bank, and vocoder all in one!

Patch into any pre-existing Eurorack rig

36-points of 3.5mm patch bay potential equip the Spectravox for seamless integration into a bounty of Eurorack and electronic instrument systems. These include standard connections to the processor's VCO, LFO, envelope generator, and much more, servicing a multitude of possible sound sculpting paths directly within or outside of the Spectravox' internal controls. No rig? No problem: Sweetwater synthesists have found that Spectravox' onboard VCO and white noise generators, an onboard program input, and the included 12V DC power supply provide more than enough standalone instrumental possibilities right out of the box.

Reviews

A fantastic studio addition.
Wow. I didn't really know what to expect with the Spectravox but I find it really intuitive and it's brought a new dimension to my studio. The ability to sculpt sounds with the multi and filters and control the carrier signals from my other gear, or from a microphone, vocoder style is really interesting and satisfying.

It's built well and sounds great. Only a half point deduction for the small knobs in the filters. I'd have preferred faders but understand the space constraints. I use this with my Matriarch, Mother 32 and DFAM.
An Interesting Addition to the Mother Ecosystem
The Spectravox is the most niche instrument in Moog's Mother Ecosystem, but don't underestimate what it can do.
Unlike other Moog instruments in this form factor, Spectravox doesn't have a sequencer. It is a complementary device. However, it can be played with external CV and gate signals like a synthesizer sound module. The basic signal path of VCO to filter(s) to VCA is there. Spectravox can produce constant sounds or drones with VCA Mode switched on. Thusly, Spectravox can do more than process voices and other instruments as a filter bank or vocoder.
Of course, it integrates well with other instruments in the Moog Mother Ecosystem as well as other Eurorack components.
Spectravox's niche appeal makes the price point hard to justify. While I enjoy the directions it is taking me, this one may only be for the experimentalists.

Want real Moog sound? Take it from the die-hard analog synth masters here at Sweetwater: buy a Moog. It doesn't matter which one; their synths start at top quality and only go up from there. Sweetwater's relationship with Moog goes way back, and some of us fondly remember the last time Bob himself came to visit. Over the years, we've had the honor of watching Moog grow and evolve, and with synthesis experts like Daniel Fisher on staff, we're still one of the first companies to catch wind of new Moog products - they never fail to impress! Whether it's a classic reissue, a breakthrough new keyboard, or even a cool effects pedal, you can be sure anything you get from Moog will make you happy, and we'd love to tell you all about it.
