Focusrite ISA C8X 26x28 USB-C Audio Interface

A high channel-count USB-C audio interface designed for advanced recording and mixing setups that require flexible routing, transformer-based preamps, and integration with external gear and patchbay systems. Transformer-Based ISA PreampsThe unit includes two ISA mic preamps equipped with Lundahl LL1538 transformers that provide clean signal capture with optional tonal shaping when driven. This allows recordings to retain detail while adding subtle harmonic character when needed. Remote-Controlled Mic PreampsIt features six additional Focusrite mic preamps that can be controlled remotely through software, offering up to 69 dB of gain for multi-mic recording setups. This makes it easier to manage large sessions with consistent gain control. Console Mode Analog SaturationConsole Mode introduces an analog saturation circuit that increases harmonics as the input level is driven higher. This gives users the option to add controlled warmth and density directly at the input stage without external processing. 430 Air High-Frequency EnhancementThe 430 Air mode adds a high-frequency lift inspired by classic ISA circuitry to increase clarity and presence. This helps improve vocal intelligibility and instrument definition in recordings. Instrument Inputs with Impedance Control The front-panel instrument inputs feature selectable impedance and pass through the same transformer-based circuitry as the mic inputs. This preserves the natural tone of guitars and bass while allowing tonal variation through impedance selection. Expanded Input and Output RoutingThe interface provides multiple line inputs and outputs designed for patchbay integration and multichannel monitoring setups. This allows users to connect external processors and monitor systems without constant re-patching. High-Resolution AD/DA ConversionIt uses 24-bit / 192 kHz converters with high dynamic range and low distortion to maintain audio accuracy during recording and playback. This ensures consistent sound quality throughout the production chain. Dual Independent Headphone OutputsTwo separate headphone outputs are included, each with independent level control for flexible monitoring. This supports multiple users during recording sessions with individual mix control. USB-C and Remote Control WorkflowThe interface is managed through USB-C connectivity and Focusrite Control software, allowing full access to routing, gain, and monitoring functions. This enables efficient session management even in complex studio setups.
