Legendary ISA Preamp Design with Modern Enhancements
At the heart of the ISA828 MkII is Focusrite's iconic ISA preamp design, which includes the legendary Lundahl LL1538 input transformer. The preamps in the ISA828 MkII are modeled after the original ISA110 modules found in the critically acclaimed Forte console. This design ensures that you get the same rich, detailed sound that has made Focusrite preamps a favorite among professionals for decades. The upgraded ISA828 MkII also features a new switching power supply that improves energy efficiency, reduces heat generation, and enhances the overall reliability of the unit, making it ideal for demanding studio and live environments.

Versatile Impedance Control for Optimal Mic Matching
One of the standout features of the ISA828 MkII is its variable input impedance circuit. With multiple settings available, you can select from four carefully chosen input impedance options, including the original ISA110 setting. This provides you with the flexibility to match the preamp perfectly to any microphone in your collection, whether you’re using dynamic, condenser, or ribbon microphones. The ability to creatively mismatch the impedance adds another layer of versatility, allowing you to experiment with different tonal characteristics and achieve a variety of sounds tailored to your needs.

Comprehensive Connectivity Options for Seamless Integration
The ISA828 MkII is designed with extensive connectivity to ensure compatibility with a wide range of setups. It includes eight rear-panel line inputs and four front-panel instrument inputs, providing flexibility for different audio sources. The front-panel instrument inputs feature both high and low impedance options, making the ISA828 MkII an excellent choice for DI (direct injection) recordings. The unit also uses 25-pin D-type connectors, which makes it easy to integrate with Pro Tools HD rigs, DAWs, and mixing desks, offering seamless compatibility with your existing setup.

High-End Digital Conversion with Optional ISA ADN8 Card
For those looking for top-tier digital conversion, the ISA828 MkII offers a slot for the optional Focusrite ISA ADN8 8-channel A-D card. This card allows for high-quality conversion to Dante, ADAT, and AES3 formats, supporting sampling rates up to 24-bit/192kHz. Whether you're working with analog or digital setups, the ISA828 MkII is ready to deliver pristine audio conversion, ensuring your recordings and mixes retain the highest possible quality. Additionally, the insert points on each channel allow for easy integration with outboard processing, providing even more creative possibilities.

Essential Controls for Complete Audio Precision
The ISA828 MkII includes several practical features that help streamline your recording process. Each channel is equipped with a highpass filter, polarity reverse switch, and a 6-segment LED peak level meter, allowing you to make precise adjustments and monitor your signal with ease. These controls help you ensure that your audio remains clean and clear throughout the recording process, whether you’re eliminating unwanted low-end rumble or correcting phase issues. The addition of insert points for outboard gear provides even more flexibility for shaping your sound.
