Focusrite ISA828 MKII 8-channel Mic Preamp + A-D Card - Dante

8-channel Mic & Line Preamp with Dante Connectivity

The Focusrite ISA 828 MkII features eight of Focusrite's renowned mic preamps in a simple-to-operate 2U enclosure, placing eight mic preamps, eight line inputs, and four instrument inputs at your fingertips. Giving you both amazing sound quality in a unit that’s convenient for your studio or live rig work, while being gentle on your budget.

Top-class preamps in budget for the serious project studio

Each mic pre has variable input impedance, to provide a range of subtly different sonic options when using microphones, including an 'ISA 110' setting, which replicates the impedance of the original Focusrite mic pre.
Up to 60dB of gain is available, with a further +20dB of continuously variable trim, providing a huge 80dB gain range. The high-pass filter has a fixed 75Hz frequency and 18dB / octave roll-off for minimising rumble, stand-borne noise and other low-frequency sounds.

Main Features:

• 8-channel mic/line preamp with front-panel instrument inputs (channels 1–4)
• Legendary ISA mic preamp design featuring Lundahl LL1538 input transformer
• Switching power supply allows for efficient, cool operation and greater reliability
• Line inputs with dedicated input connectors and front-panel selector switches
• Switchable input impedance, including classic ISA 110 setting
• Slot for optional ISA ADN8 8-channel A-D card (available separately)
• Switchable insert points when used with ISA ADN8 card
