SSL 12

A USB-C interface with four SSL preamps, eight outputs, 32-bit converters and CV outs for hardware synths — a standout in the pro tier. Loopback and phantom power round out a capable studio hub for multi-mic and synth-driven setups. Single-mic users are overspending here; the SSL 2 MkII covers that case for less.
