●0dB is referenced to 0.775V.
●The AC voltmeter used in the procedures must have an
input impedance of 1MΩor more.
●Unless specified otherwise, adjustments and checks are
made in FWD direction.
2-2 ELECTRICAL ADJUSTMENT
2-2-1 Precautions
●Before performing adjustments and checks clean and
demagnetize the entire tape path.
●In general, adjustments and checks are made in the order
of Lch then Rch. Double REF. Nos. indicate Lch/Rch.
