PROS
- • Excellent preamps deliver clean, detailed sound with Focusrite's signature warmth.
- • The comprehensive I/O count simplifies complex recording setups considerably.
- • Air mode subtly enhances vocals and instruments with pleasing harmonic richness.
- • Built-in talkback is surprisingly useful for directing musicians during sessions.
CONS
- • The USB 2.0 connection feels dated; USB 3.0 would offer more headroom.
- • The 19” rackmount format limits desktop use; requires rack space or adapter.
- • While versatile, lacks ADAT expandability for significantly more channels.
