Bi-Wiring Connections

Figures 8 through 10 show two bi-wiring options, single stereo ampliﬁer and dual stereo ampliﬁer modes. For passive and bi-wire connections, set the switch to the Normal/Bi-Wire position (Figure 8a).

Important

1.The external “strapping bars” that normally connect the Century Gold’s low-frequency and high-frequency terminals must be removed before bi-wiring. To remove the shorting straps, simply loosen and slide the bars off to the side (Figure 11).

2.Never connect two ampliﬁers to the same loudspeaker without ﬁrst removing the strapping bars. Operating two ampliﬁer channels without removing the strapping bars can seriously damage your ampliﬁers!

3.If you have hooked up your Century Gold loudspeakers in any of the bi-wire conﬁgurations indicated, it is not advisable to use additional speakers separately or simultaneously.

4.As with conventional one-ampliﬁer connections, make sure that all speaker cables are the same length.
