Neural DSP Quad Cortex Pré-amplificador/amplificador em rack

Neural DSP Quad Cortex — Flagship Floorboard Amp Modeler

The Neural DSP Quad Cortex is the most powerful floorboard amp modeler on the market, packing six dedicated cores into a 1.95 kg chassis. 4× SHARC+ and 2× ARM processors handle four amp chains, stereo reverbs, and dozens of effects with ultra-low latency, while a 7-inch touchscreen and 11 dual-function rotary footswitches make editing feel closer to a smartphone than a rack unit. This modeler is the right choice for guitarists and bassists who want studio-grade tone shaping in a single box that replaces an amp rack, pedalboard, and audio interface.

What Sets the Quad Cortex Apart

Neural Capture is the headline feature: a biomimetic AI engine that listens to any physical amplifier, overdrive, or cabinet and produces a faithful digital replica, complete with sag, bloom, and volume-knob cleanup. Neural Capture V2 runs in Cortex Cloud for higher-resolution modeling of touch-sensitive fuzzes and tube amps, while V1 stays fully offline for everyday use. Plugin Compatibility (PCOM) loads selected Neural DSP plug-ins directly onto the unit, turning the floorboard into a portable rig that travels with the player's entire studio.

Processing Power and I/O

Six cores mean the player never has to choose between running a high-gain amp, a stereo reverb, and a parallel effects chain — the engine handles all of it without audible latency. The I/O section is laid out for studio and live use, with Neutrik connectors, switchable 48 V phantom power, and per-preset routing.

• Type: Multieffect — floorboard amp modeler and multi-effects processor
• Inputs: Combo (XLR/Jack), MIDI IN, Return — dual combo jacks accept TS, TRS, and XLR with variable impedance and built-in mic preamps
• Outputs: XLR, Jack 6.3 mm, Headphone Jack 6.3 mm, Send, MIDI OUT/Thru, Expression — balanced mono XLR and TRS outs, dual expression pedal inputs, and a dedicated headphone jack for silent practice

Controls, Build, and Connectivity

The control surface is engineered for live performance: 11 stainless steel actuators twist like real knobs and stomp like traditional switches, so the player can tweak amp parameters mid-song without taking hands off the instrument. The chassis is built to survive the road, and the touchscreen is shielded against stomps and cable drops.

• Controls: Footswitch, Volume — 11 dual-function rotary footswitches plus a dedicated tap/tune switch
• Effects Loop: Yes — dual stereo FX loops for embedding external pedals or running the 4-cable method
• Headphone Output Port: Yes — quiet practice and direct monitoring without an amp
• MIDI Interface: Yes — full MIDI In and Out/Thru for automating every parameter and controlling external units
• DI Output: Yes — balanced XLR outs feed a front-of-house mixer or recording interface directly

Capture, Effects, and Onboard Tools

Beyond amp modeling, the unit ships with a deep effects library, a built-in looper, and a chromatic tuner — everything a working guitarist needs in one box. Wireless connectivity keeps the tone library growing without a laptop.

• Reverb: Yes — multiple reverb algorithms including Nordic Concert Hall and Studio Plate 70 in CorOS 4.0.0
• Tuner: Yes — ultra-fine resolution chromatic tuner with cents display, accessible from a dedicated footswitch
• Neural Capture: V1 offline + V2 cloud — replicates any amp, cab, or pedal with biomimetic AI
• Library: 90+ amps, 100+ effects, 1,000+ IRs — plus 3,072 user preset slots across 12 setlists

Who the Quad Cortex Is For

The Quad Cortex is the right choice for touring guitarists and bassists who need a single floor unit to replace a rack of amps, a pedalboard, and a capture profiler. Studio players benefit from the USB audio interface, Cirrus Logic converters, and per-preset routing that lets them re-amp and track without leaving the desk. Players who already own a beloved amp or overdrive can capture it once and carry that exact tone to every gig, rehearsal, and session. Four independent signal paths even let two guitarists share one unit on stage, which makes it a practical choice for duos and tight travel setups.

Neural DSP — From Plug-ins to Flagship Floor Hardware

Neural DSP built its reputation on studio-grade guitar and bass plug-ins used by producers and session players worldwide, and the Quad Cortex represents the company's move into dedicated hardware. The unit was first announced at Winter NAMM 2020 and has since collected "Best Multi-Effects Pedal" and "Best Amp Modeler" awards from Guitar World, MusicRadar, and Premier Guitar across multiple years. Continuous CorOS firmware updates — including the recent 4.0.0 release with new virtual devices and Gig View footswitch access — show a platform that keeps expanding long after purchase.
