The Jadis DA30 is not a "plug and play" device. It is a precision instrument. The original manual (typically a 12-16 page booklet) provides critical information that cannot be guessed:
1 Tape output, Loudspeaker terminals (selectable impedance) Input Sensitivity: Approx. 400mV for rated power Power Consumption: 275W Unpacking and Installation
Dust the chassis only when the unit is cold. Use a dry microfiber cloth. Avoid harsh chemical cleaners on the gold faceplate, as they can strip the protective lacquer over time.
