Connections
• If you use two sets (A and B), the impedance of each speaker
must be 8
Ω
or higher. When only using one set of speakers (A
or B), use speakers with an impedance of 4
Ω
or higher.
• Do not let the bare speaker wires touch each other or do not let
them touch any metal part of this unit. This could damage this
unit and/or the speakers.
• All connections must be correct: L (left) to L, R (right) to R,
“+” to “+”, and “–” to “–”. If the connections are faulty, no
sound will be heard from the speakers, and if the polarity of the
speaker connections is incorrect, the sound will be unnatural
and lack bass. Also, refer to the owner’s manual for each of
your components.
• Connect your turntable to the GND terminal to reduce noise in
the signal. However, you may hear less noise without the
connection to the GND terminal for some turntables.
