Built for high-end studios and enduring workflows, the ISA 828 MkII combines eight of Focusrite’s legendary transformer-based mic preamps with flexible analog/digital topology. Featuring adjustable impedance, instrument inputs, high-pass filters, and optional Dante/ADAT/AES3 outputs via expansion card, it delivers pristine sound, tonal richness, and pro-level adaptability—core gear for discerning setups at Soundium.

Kluczowe cechy

• Eight ISA mic preamps with Lundahl LL1538 transformers: Vintage console tone with modern control, capturing presence, depth, and fidelity
• Multi-source input capability: Mic and line-level inputs on all channels plus front-panel instrument jacks on channels 1–4
• Wide gain range (up to 80 dB): Stepped mic gain (0–60 dB) plus continuous 20 dB trim delivers extreme flexibility
• Selectable input impedance & high-pass filter: Four impedance modes including classic ISA 110, and a built-in 75 Hz 18 dB/octave low-cut filter to tame rumble
• Per-channel metering & inserts: Six-segment LED meters, insert points for outboard gear, and calibrated level trimming for seamless integration
• Modern, efficient power design: Quiet, reliable switched-mode PSU reducing heat and enhancing durability
• Optional ADN8 expansion card: Adds ADAT, AES3 (DB-25), Dante audio-over-IP, and Word Clock I/O—up to 24-bit/192 kHz digital outputs

Zastosowanie

Perfect for high-end studio tracking, live room capture, mobile recording rigs, and setups requiring both warmth and modern digital connectivity. Ideal as a front-end for converters, analog color extension, or I/O expansion via Dante or ADAT.

Kompatybilność

Uses analog outputs by default (DB-25), with inserts built for analog processing. Supports digital output when paired with ADN8 card—stream via Dante, ADAT, AES3. Clock sync via Word Clock I/O. Fits seamlessly into both analog and digital studio infrastructures.

Zalety i wady

✅ Zalety:

• Iconic ISA tone with modern flexibility
• Massive gain range and adjustable impedance for tonal shaping
• Insert capability before digital conversion
• Optional digital expansion via Dante, ADAT, AES3 adds future-ready connectivity

⚠️ Wady:

• Analog only without ADN8—digital output requires separate purchase
• Large, heavy rack unit—not intended for mobile rigging without support
• Analog inserts and options add complexity to signal routing

The Focusrite ISA 828 MkII blends revered analog character with modern studio flexibility. Whether you're chasing classic mic tone or building a versatile, expandable ecosystem, it delivers unmatched sonic richness—available now at Soundium.
