speaker cords and short-circuit plates.  
The impedance of the speaker is 6 . Before connecting it to  
your amplifier, check the speaker impedance range of your  
amplifier. If the impedance of this speaker is out of the speaker

When using a microphone, do not aim it at the speakers or  
use it near the speakers; otherwise, the howling which occurs  
may damage the speakers.  
7 Bi-wiring connection  
This speaker is bi-wireable. Comparing with the conventional  
connection, the bi-wiring connection makes the sound field  
larger, deeper, and richer.  
Before replacing the cartridge, always turn off the power to the  
turntable; otherwise, the clicking noise may damage the  
speakers.  
1 Loosen all speaker terminal knobs and detach the  
short-circuit plates.  
Use speaker cords as follows;  
Buy thick speaker cords rather than thin cords, and make  
them as short as possible for connection.  
Use speaker cords of the same length for both left and right  
speakers.  
Do not use long speaker cords; otherwise, the sound quality  
may deteriorate.  
Using a special speaker cord such as a litz wire, a coaxial  
cable, or a cord which has the specified connecting  
directionality may influence the sound quality.  
Short-circuit plates  
2 Connect the “FULL RANGE” terminals and “LOW  
FREQUENCY” terminals separately to the speaker  
terminals of the amplifier.
