Built for Complex Studio Workflows
- Four DiscretePRO preamps: track microphones, instruments or line sources from the front panel.
- Eight analog input paths before digital expansion: four preamp channels plus four additional line inputs.
- Four hardware inserts: patch compressors, EQ or other outboard processors directly into channels 1-4.
- Dual monitor pairs: switch between two sets of speakers for mix comparison.
- Two independent headphone paths: useful for engineer and performer monitoring.
- Reamping: two analog line outputs can operate at instrument level for compatible reamp workflows.
- ADAT expansion: add compatible digital preamps or converters without replacing the interface.
- 24-bit conversion up to 192 kHz: supports high-resolution production workflows.
Who Is AudioFuse Studio For?
This is best for producers and engineers who need more than a basic two-channel interface but still want hands-on desktop monitor control. It is especially useful for hybrid studios with microphones, synths, turntables, outboard processors, multiple speaker pairs and ADAT expansion.
