Nashville, TN, August 18, 2026 — Adding to an evolving ecosystem of groundbreaking production tools, Harrison Audio announces its new Flex-10 high-performance USB/ADAT audio interface.
Able to function as a centerpiece for a compact studio or mobile set up, Flex-10 carries the classic analog character that Harrison is known for—present on countless recordings including landmark albums by Led Zeppelin, Supertramp, Nirvana, The Rolling Stones, Michael Jackson, and more.
The Flex-10 is the perfect desktop production tool, packed with analog mojo and featuring an intuitive, tactile control surface. With two channels of high-performance Harrison preamplifiers, each featuring
H-DRIVE™ real transformer saturation, Flex-10 carries the unmistakable vibe of '70s mixing console right from the input stage. Classic Harrison high-pass and low-pass filters are available on both channels, derived from the filters on the iconic 32 Series consoles—perfect for carving space around input sources and shaping your mix from the very first take. Each channel also includes buttons for line level, 48V phantom power, -20 dB pad, and phase inversion, along with two conveniently positioned 1/4" inputs in front of the interface—enabling easy connections to guitars, basses, vintage synths/drum machines, and other instrument-level sources.
Just like Harrison's renowned 32Classic console, Flex-10 pairs analog heritage with modern digital compatibility. Its next gen 32-bit/192 kHz converters ensure pristine audio capture, while its eight channels of ADAT I/O offer expandability for larger recording sessions or integration with other audio tools. Ideal for pairing with Harrison D510r 500 Series rack and D510UA ADAT interface to create a powerful 10in/12-out hybrid production solution.
A fully-featured monitoring section provides two independent monitor outputs; each with dedicated level controls, as well as two high-end headphone outputs for dual monitoring. Flex-10 also includes MIDI I/O over 3.5mm TRS connectors, providing additional control and connectivity for drum machines, synths, and other equipment.
With an extremely user-friendly interface and flexible sonic architecture, Flex-10 is able to move effortlessly between detailed ‘reference’ recordings, warm saturated tones, and everything in between. Flex-10 also makes it easy to integrate outboard gear like compressors, 500 Series modules, or even boutique analog pedal effects with its dedicated balanced insert points on both channels. Perhaps the most visually striking feature on the Flex-10 is its VU meters, which are a useful visual cue during recording or playback of your signal.
Flex‑10 comes bundled with the Harrison Creator Pack—a powerful, inspiring collection of premium virtual instruments, plug‑ins, loops and samples from Harrison's top‑tier partners including Solid State Logic, Slate Digital, Sonible, Loopcloud, AAS, Native Instruments, IK Multimedia, and more. It also ships with a full license for Harrison Mixbus 12, the award‑winning, analogue console-inspired digital audio workstation containing Harrison’s signature console EQ on every channel, giving users the ultimate foundation of hardware‑and‑software studio in one complete package.
Celebrated for their unmistakably smooth sonic signature and intuitive workflow, Harrison consoles became the centerpiece of studios worldwide. For over five decades, Harrison has been at the forefront of audio innovation, delivering the legendary sound and studio flexibility that artists, producers, and engineers rely on to create timeless music. From the iconic 32Classic console and Mix Strip to the cutting-edge D510 500 Series System and now the Flex-10, every Harrison product carries the same heritage, craftsmanship, and forward-thinking technology—proving that great sound and pioneering design go hand in hand.

It supports 32-bit/192 kHz conversion and includes two Harrison mic preamps, H-DRIVE™ transformer saturation, high-pass and low-pass filters, ADAT I/O, MIDI I/O, two monitor outputs, two headphone outputs and bundled production software.
Who is Harrison Flex-10 designed for?
Flex-10 is intended for artists, producers, musicians and small studio users who need more input, output and monitoring options than a basic entry-level interface provides. Typical use cases include recording vocals, guitars, bass, synths, drum machines and external audio hardware.
Why upgrade from an entry-level audio interface to Harrison Flex-10?
Compared with many entry-level interfaces, Flex-10 provides expanded I/O, ADAT connectivity, two independent monitor outputs, two headphone outputs, balanced insert points and input-stage tone controls. These features are useful when a recording setup grows beyond one or two sources and requires more routing, monitoring or external hardware integration.
What makes Harrison Flex-10 different from a basic 2-in/2-out interface?
A typical 2-in/2-out interface is designed for a small number of inputs and outputs. Flex-10 provides 10 inputs and 12 outputs, including ADAT I/O for expansion, two front-panel Hi-Z instrument inputs, line inputs, MIDI I/O over 3.5 mm TRS connectors, two headphone outputs and two independent monitor outputs. It also includes analogue input features such as H-DRIVE™ transformer saturation, filters, pad, phase inversion and phantom power.
Does Harrison Flex-10 have professional mic preamps?
Yes. Flex-10 includes two Harrison mic preamps. Each input channel also includes H-DRIVE™ real transformer saturation, high-pass and low-pass filters, line level switching, 48V phantom power, a -20 dB pad and phase inversion.
What is H-DRIVE™ on the Harrison Flex-10?
H-DRIVE™ is a transformer saturation circuit included on each of Flex-10’s two input channels. It is used to add analogue-style saturation at the input stage, with the amount controlled from the interface.
Can Harrison Flex-10 be expanded with ADAT?
Yes. Flex-10 includes eight channels of ADAT I/O. This allows the interface to be connected to compatible ADAT-equipped devices for additional digital inputs and outputs.
