Focusrite ISA 828 MKII

No, the digital expansion card is an optional add-on. The base unit provides analog XLR and TRS connectivity, but you will need to purchase the A-D card separately if you require Dante, ADAT, or AES3 digital outputs.

Variable impedance allows you to change how the preamp interacts with your microphone's output. By switching between settings, you can subtly alter the frequency response and transient behavior, letting you brighten up a dark ribbon mic or smooth out a harsh condenser without using EQ.

Yes, the ISA 828 MKII includes dedicated instrument inputs on the front panel for each channel. This allows you to plug guitars, basses, or synthesizers directly into the unit for high-quality DI recording.

While it is designed as a rack-mountable unit for studio environments, it is quite heavy and requires a rack case for transport. It is best suited for permanent studio installations rather than portable, on-the-go setups.

Yes, each of the eight channels features independent 48V phantom power switching, allowing you to use condenser microphones alongside dynamic or ribbon mics simultaneously.

The ISA 828 MKII is based on the classic Focusrite ISA transformer-based design, which offers a slightly warmer, more colored sound compared to ultra-clean, transparent preamps. It provides a professional, 'finished' character that works exceptionally well on drums, vocals, and acoustic instruments.
