CONNECTIONS TO THE AMPLIFIER
· bi-wiring
Bi-wiring requires four-pole speaker cable or two pairs of
normal two-pole loudspeaker cables where one speaker
cable pair drives the bass unit and the other the midrange/
treble unit of the speaker.
Dedicated four-pole Gradient speaker cables have following
colour codes:
Black = bass minus
Red = bass plus
Blue = midrange/treble minus
Yellow = midrange/treble plus
Connect red and yellow lead to positive or plus terminal of
the amplifier. Similarly connect the black and blue lead to
negative or minus terminal of the amplifier. Connect both
speakers in the similar way.
If you are not using the dedicated Gradient speaker cables,
connect the speakON cable connector to the cable as
follows:
1 - = bass minus
1+ = bass plus
2 - = midrange/treble minus
2+ = midrange/treble plus
