Pros & Cons

👍 Pros

  • Features premium, relay-controlled analogue circuitry that emulates the classic Focusrite ISA 110 preamp sound.
  • Offers an impressive 118dB dynamic range and 129dBu EIN, ensuring the natural sound of sources is preserved with ultra-low noise.
  • Dedicated channel inserts on every channel allow for tracking through outboard gear, capturing its true character.
  • Provides ultra-low noise and ultra-low distortion A-D conversion for professional-sounding tracks ready for mixing.
  • Exceptional D-A conversion maintains audio quality when sending signals to analogue compressors, EQs, and effects.

👎 Cons

  • While it emulates classic Focusrite ISA 110, it's not the original hardware, which might be a distinction for purists.
  • Requires an ADAT-compatible audio interface to expand I/O, meaning it's not a standalone recording solution.
  • The JFET guitar inputs are a specific feature for guitarists and may not benefit users recording other instruments primarily.
  • The "Hitmaker Expansion" software bundle is an added value but does not directly enhance the hardware's core audio performance.
  • "Stay plugged in with inserts on every channel" is a functional statement, but the inserts themselves are not a unique benefit only to this product.
