• Tripartite the 4Ω, 70V and 100V terminals cannot be used at the same time.
• Impedances indicated at the terminal represent the total speaker system (load) impedances.
Total impedances of 100V line: Total impedances of 70V line:
· 330Ω (A-2030) · 170Ω (A-2060) · 170Ω (A-2030) ) · 83Ω (A-2060)
· 83Ω (A-2120) · 42Ω (A-2240) · 42Ω (A-2120) · 21Ω (A-2240)
Be sure to attach the supplied terminal cover after connection completion.
Because high voltage is applied to the speaker terminals, never touch these terminals to
avoid electric shock.
