Hauptmerkmale

• Transformer-coupled mic preamp (Lundahl LL1538): Iconic ISA design delivers rich, open tone with selectable impedance including the classic ISA 110 setting
• Independent DI channel: Front-panel instrument input with high/low impedance, independent gain control, DI output, and amp feed—perfect for direct recording or amp splitting
• Selectably variable impedance: Four mic input impedance choices—Low, ISA 110, Medium, High—letting you shape tone to match any mic
• Insert point before optional A-D conversion: Route hardware processing like EQ or compression into the signal chain before conversion
• Headphone monitoring with cue mix: Integrated headphone output with level control, monitoring either the input or an external cue feed
• Backlit moving-coil VU and LED meters: Visual feedback with adjustable calibration and pre/post-insert monitoring options for precise level control
• Optional ADN2 A-D card: Adds Dante, ADAT, AES3, S/PDIF, and Word Clock connectivity at up to 24-bit/192 kHz—perfect for digital workflows
