CAUTION • When connecting with low impedance, take note of the total impedance. • When connecting speakers with high impedance, be sure that the total rated input capac- ity of the speakers does not exceed the output power of the amplifier. NOTICE When using a high-impedance speaker connection, make sure the audio signal is passed through an 60 Hz or above high-pass filter before being input to the speakers. Using Loop-Through Terminals For this method, cables are connected from terminals 1 and 4 to the subsequent speaker. Cables with a thickness of at least AWG24 (0.2 sq) and up to AWG12 (3.5 sq) can be used. If the Euroblock plug is disconnected from a speaker, all subsequent speakers will not work. This can be useful to identify which speaker has a problem. Paralleling Input Terminals For this method, cables are connected to terminals 2 and 3 of each speaker. Connect two cables to one terminal. Cables with a thickness up to AWG17 can be used. Since the cables are connected via Euroblock plugs, subsequent speakers can work properly.
