Harrison Audio has launched the Flex-10, a 10-in/12-out USB-C audio interface bringing its console sound—used on records by Michael Jackson, Nirvana, and The Rolling Stones—into a desktop unit. The hardware packs 32-bit/192kHz converters, H-Drive transformer saturation preamps, and tactile controls designed to mimic a vintage mixing desk.
Engineering the Console Sound for the Desktop
The name Harrison has been synonymous with mixing consoles that shaped the sonic landscapes of classic rock and pop. The new Flex-10 interface packages that analogue character into a compact form factor meant for modern desktop environments. Instead of forcing engineers and musicians to navigate complex software menus for basic gain staging, the unit relies on a tactile surface that keeps critical controls directly under the user’s fingers.
At the core of the hardware are two Harrison mic preamps. Each preamp features H-Drive, a real transformer saturation circuit engineered to inject the distinct warmth of a 1970s studio console right into the input stage.
A Closer Look at the Hardware Architecture
Flexibility dictates the design of the Flex-10’s I/O array. The unit operates as a 10-input, 12-output system driven by high-performance 32-bit/192kHz converters. Both microphone channels include high-pass and low-pass filters directly derived from Harrison’s 32 Series consoles, allowing creators to carve out unwanted low-end rumble or tame harsh high frequencies before the signal ever hits the analogue-to-digital converters.
Physical connectivity options are extensive for a desktop unit:
- Two front-panel 1/4-inch Hi-Z instrument inputs designed for guitars, basses, and vintage synthesizers.
- Balanced insert points on every channel for patching in outboard gear like compressors, 500 Series modules, or analogue pedals.
- Eight channels of ADAT input/output, enabling users to scale up their session sizes or pair the unit with gear like Harrison’s D510 to build out a larger studio rig.
- MIDI input and output over 3.5mm TRS connections to integrate hardware synths and drum machines.
- Two independent monitor outputs on dedicated level controls, alongside dual headphone outputs for tracking sessions.
Across the top of the chassis, a pair of physical VU meters provides a real-time moving picture of signal levels during tracking and playback. The hardware is fully class-compliant on Mac systems, while Windows users can run the unit via a dedicated ASIO driver supplied by the manufacturer.
Bundled Software Ecosystem
Hardware is only half the equation in modern production environments. Harrison ships every Flex-10 unit loaded with an extensive software package. Users receive a full commercial license for Mixbus 12, the company’s console-style DAW featuring built-in EQ on every channel.
Additionally, the hardware includes the Harrison Creator Pack. This bundle stacks virtual instruments, plug-ins, loops, and samples contributed by major industry developers, including Solid State Logic, Slate Digital, Native Instruments, and IK Multimedia. By combining the physical preamp topology with a robust software suite, the Flex-10 functions as a comprehensive, all-in-one studio ecosystem designed for producers looking for high-end analogue processing without the footprint of a massive mixing console.
