Neural DSP Quad Cortex Preamp/Rack Amplifier

Quad Cortex is the most powerful floor modeler on the planet. With a total of 6 cores (4x SHARC+ and 2x ARM Cortex-A5 running at 500MHz each), this ludicrous amount of processing capacity provides limitless sound design possibilities.
Capture, share and download your favorite rigs’ sounds. Equipped with unique biomimetic AI technology, Quad Cortex can learn and replicate the sonic characteristics of any physical amplifier, overdrive, and cabinet with unprecedented accuracy.Unlike any other, sophisticated neural network algorithm perceives sound akin to human perception, making it the most natural-sounding capture solution on the planet. Neural DSP collaborating with some of the best producers and sound designers to provide an ever-growing collection of free rig captures in addition to full-circuit models.
Using advanced mechanical design and manufacturing techniques, they managed to not only build the most powerful floor modeler/multi-effects processor on the planet, they also managed to pack it all in an extremely compact format.
Discover Users, Presets, and Neural Captures via the Cortex Mobile app for iOS and Android devices.Linking your Neural DSP account to your Quad Cortex allows you to create backups, share content, and download items from other users. It also unlocks the Impulse Response Library, where you can transfer IRs to your Quad Cortex and manage the IRs stored on your account.

Тype

Тype: Multieffect

Multieffect is a device that combines multiple effects into a single unit. It allows players to switch between various sound effects - such as distortion, delay, reverb, modulation, or dynamics - and often includes the ability to create and save custom presets. Multieffects are popular for their versatility, compact design, and convenience in both live performance and studio use.

External FX Loop: Yes

The Effect Loop makes it easy to connect external effects. This feature provides the ability to add and edit various sound effects without affecting the underlying signal. It's a great solution for musicians and sound engineers who need more flexibility and creativity in sound processing.

Headphone Output: Yes

The headphone output allows direct connection of headphones for private listening. This output provides a convenient way to enjoy the sound without disturbing others or ambient noise.

Reverb: Yes

The reverb effect allows you to simulate various acoustic environments, from small rooms to grand halls. Reverb is ideal for enhancing dynamics, adding space to recordings, or creating a unique sound environment during a live performance.

Tuner: Yes

The built-in tuner allows you to quickly and accurately tune instruments directly from the unit. This feature eliminates the need for additional tuning devices, increasing convenience and efficiency on stage or in the studio.

MIDI Interface: Yes

It supports MIDI, allowing you to connect and communicate with other MIDI-compatible devices. This feature extends control and integration into the larger music environment, increasing flexibility and creativity in music creation.

DI Output: Yes

Equipped with a DI output that allows direct and balanced transfer of the audio signal to mixers or recording devices without loss of quality. This output minimizes noise and interference, making it ideal for professional environments where it is important to maintain a clean and strong signal over extended connections. The DI output is ideal for both live performance and studio recording.

Absolutely amazing device. Top notch guitar tech. The only remark is that by 2026, it would already be nice to have USB-C instead of USB-A 🙂

To co lezie z Quad Cortex je nieco nadherne. Perfektny zvuk cez clean, ambient, rock az po metal. Perfektne zmaknute UI a intuitivne nastavenia. Osobne pouzivam aj inde zakupene IR reproboxy s V30. Objednal by som si Quad Cortex uz pred rokmi ale clovek niekedy pocka na recenzie realnych ludi a nie iba od youtuberov . Za mna rozhodne sikovnejsie a aj zvukovo lepsie zariadenie ako Kemper. (samozrejme so mnou nemusite suhlasit). Velka vdaka patri vyvojarom aj v tom, ze ich updaty obsahuju casto zasadne vylepsenia, nie iba male opravy.

Recommended product

What's coming out of the Quad Cortex is something wonderful. Perfect sound through clean, ambient, rock to metal. Perfectly crafted UI and intuitive settings. Personally I also use IR speakers purchased elsewhere with the V30. I would have ordered a Quad Cortex years ago but sometimes you have to wait for reviews from real people and not just youtubers. For me definitely a smarter and also sonically better device than the Kemper. (of course you don't have to agree with me). A big thank you to the developers also in that their updates often contain major improvements, not just small fixes.

i had many other guitar multi effects which i forgot how to use after one week because they have 48587264 buttons. this one is the best implementation so far. sounds great and it has the most user friendly and intuitive interface. totally recommend.

zvuk, ovládateľnosť, rozmery, vzhľad, jednoducho moderný nástroj, mal som kemper, helix, ale QC mi vyhovuje najviac a zvukovo je vynikajúci hneď po prvom zapnutí, manuál nebol potrebný, stačilo zapnúť a hrať, žiadne zložité menu, dodatočné ekvalizéry a triky na dosiahnutia použiteľného zvuku, instantná radosť, v novom updajte pridali metronóm, do QC mám zapojený aj mikrofón na spev, už len skúšať a hrať

sound, controllability, size, appearance, just a modern instrument, I had kemper, helix, but QC suits me the most and sonically it is excellent right after the first switching on, manual was not needed, just switch on and play, no complicated menus, no additional equalizers and tricks to achieve usable sound, instant joy, in the new update they added a metronome, I have a microphone plugged into the QC for singing, just to try and play
