CONNECTIONS TO THE AMPLIFIER
· bi-amping
Bi-wiring requires four-pole speaker cable or two pairs of
normal two-pole loudspeaker cables. The speakers are
driven by two amplifiers. One amplifier drives the bass units
and another the midrange/treble units of the speakers. Bi-
amping enables the bass level adjustment if one of the
power amplifiers is equipped with volume control.
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 lead to positive or plus terminal of the amplifier
1. Similarly connect the black lead to negative or minus
terminal of the amplifier 1. Connect both speakers in the
similar way.
Connect yellow lead to positive or plus terminal of the
amplifier 2. Similarly connect the blue lead to negative or
minus terminal of the amplifier 2. 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
