CAUTION

Do not touch the terminals or metal parts 
of cords connected to the terminal.  

NOTICE

• If connecting speakers to multiple connectors of a 

same channel results in a parallel connection, 
make sure that the total impedance of the speakers 
to be connected is not excessively low.

• The PX amplifier adopts BTL (Balanced Trans-

former Less) amplifier circuits. Connecting both ter-
minals of channels A and B and contact between 
the terminal and the chassis may cause a failure or 
malfunction. Be careful to not connect or contact

This 

 mark indicates a dangerous electrically live terminal. When 

connecting an external wire to this terminal, it is necessary either to 
have “a person who have received appropriate guidance on handling” 
make the connection or to use leads or a cord that have been manufac-
tured in such a way that the connection can be made simply and with-
out problem.
