Z/Ω
The input impedance, Z, = 75 Ω
The input impedance, Z, = 150 Ω
(or 120, 124, 135 or 140 Ω depending on
the version)
The input impedance, Z, = 600 Ω
INPUT
Toggles between the selected input
impedance Z and high input impedance
(∞)
This key sequence toggles between the
balanced (BAL) and the coaxial input
(UNBAL).
