The Flex-10 audio interface from Harrison Audio offers advanced technical specifications tailored for professional audio production. At its core, the Flex-10 is a 10-input/12-output interface, utilizing USB-C connectivity to ensure fast and reliable signal transmission. It supports high-resolution audio processing at 32-bit/192 kHz, allowing for detailed and high-quality sound capture and playback.

Central to the Flex-10’s design are its two channels of Harrison mic preamps. These preamps are equipped with H-DRIVE transformer saturation, designed to enhance audio warmth and character. Each channel is also fitted with essential controls, including buttons for line level adjustment, 48V phantom power for condenser microphones, a -20 dB pad to manage input sensitivity, and phase inversion to correct phase issues. Additionally, each channel includes a front 1/4″ input for instrument or line-level sources.

For connectivity, the Flex-10 is equipped with eight channels of ADAT I/O, allowing for expansion with additional digital audio channels. It also provides two independent monitoring outputs for precise control over audio playback. Two headphone outputs offer monitoring flexibility for different users. Furthermore, the device includes two MIDI I/O connections via 3.5mm TRS connectors, extending its capabilities to integrate with various MIDI devices. Overall, the Flex-10 is a versatile and powerful solution for desktop audio production.

The Harrison mic preamps integrated into the Flex-10 audio interface are designed to provide high-quality audio processing with enhanced tonal characteristics. A standout feature of these preamps is the H-DRIVE transformer saturation, which adds warmth and musical harmonics to the sound, emulating the rich qualities of classic analog audio processors. This feature is particularly beneficial for vocals and acoustic instruments, offering a fuller and more engaging sound profile.

Each mic preamp channel on the Flex-10 is equipped with a set of comprehensive controls to tailor the audio input precisely. These controls include a high-pass filter and a low-pass filter. The high-pass filter helps to eliminate low-frequency noise, while the low-pass filter manages high-frequency content, ensuring clarity and focus in the desired audio bandwidth. Additionally, every channel is equipped with buttons for adjusting the line level, providing a -20 dB pad for managing high-gain signals, and activating 48V phantom power, essential for powering condenser microphones.

The channels also incorporate phase inversion switches, which resolve phase issues that can occur when combining multiple microphones or audio sources. Each channel offers a front-accessible 1/4″ input, allowing for easy connection of instruments or other line-level devices. These features collectively ensure that the Harrison mic preamps within the Flex-10 deliver a versatile, high-performance audio recording and production experience.

The Flex-10 desktop audio interface connects to host computers via USB-C, providing the primary pathway for audio I/O and control communication. For digital expansion, the unit offers eight channels of ADAT I/O, enabling additional optical digital inputs and outputs to integrate external converters or expand the channel count of a studio system. This configuration supports routing multiple digital sources and sinks alongside the interface’s native analog I/O.

Monitoring is handled through dedicated outputs with independent control, allowing separate level adjustments for monitoring paths. The Flex-10 also provides two headphone outputs, offering simultaneous personal monitoring for multiple users or performers. These monitoring options are intended to give flexible cueing and playback setups in a compact desktop environment.

MIDI connectivity on the Flex-10 is provided via two MIDI I/O ports using 3.5mm TRS connectors, allowing the interface to send and receive MIDI data with compatible devices and adapters. The combination of USB-C, ADAT expansion, independent monitoring outputs, dual headphone jacks, and TRS-based MIDI I/O positions the unit to interface with a range of modern studio equipment and workflows.
