Conventional Biamping

Biamping

The loudspeakers have two sets of binding posts that can be used for biwiring or biamping. These posts are joined with bridge clips for normal operation.

Make sure the bridge clips are removed from the loudspeakers when you want to biamp or biwire

them. If not, this may cause damage to your ampliﬁer..

In a biamp system, each loudspeaker can be driven by two separate ampliﬁer channels; one to drive the woofers and one to drive the ribbon.

Biamping with a Sunﬁre Theater Grand Ampliﬁer

The front channels of Sunﬁre's Theater Grand Ampliﬁers each have two pairs of outputs. In a biamp system, use the current source to drive the ribbon and a separate channel's voltage source to drive the woofers.

This example shows the connections for biamping a right front speaker.

Sunﬁre TGA Series Ampliﬁer outputs

•Connect the ampliﬁer’s right rear output to the right loudspeaker’s woofer input terminals. Connect the ampliﬁer’s right front current source output to the ribbon input terminals.

•Both ampliﬁer channels are fed with the same (right, front) line-level signal from your preamp.

If you are not using a Sunﬁre Theater Grand Series ampliﬁer (or you are using the current source outputs for something else), then connect sepa- rate ampliﬁer channels to the woofer terminals and ribbon terminals. The ampliﬁers should be of identical power output and performance. Both ampliﬁer channels are fed with the same line- level signal from your preamp.
