1. AMP INPUT TERMINALS
These terminals are connected to the output of a low-impedance amplifier like the Inter-M OT-4240
(4
Ω
/60W), OT-4480 (4
Ω
/120W) or OT-4960 (4
Ω
/240W).
2. SPEAKER OUTPUT TERMINALS
These output terminals may be connected with high-impedance distributed speaker systems.
For 120VAC operation, the 70V output terminal is recommended. For 230VAC operation, the 100V or 70V
terminals may be used.
