- Høy holdbarhet, pålitelighet og ytelse
- Fire mikrofoninnganger, to AUX-innganger og én opptak-utgang
- Høyttalerutgang for konstant spenning (100V) og lav impedans (4Ω)
- Drives av vekselstrøm
- Mute-funksjon
- Uavhengig volumkontroll for inngang og hovedvolumkontroll
- Uavhengig tonekontroll av boost og cut for både høy og lav frekvens
- MIC 1 er utstyrt med phantom power for kondensatormikrofon og har også mulighet for chime mikrofon
