Sunfire True Subwoofer Signature and Standard Version Connections, Speaker Level connections

Connections

Please consider the following when set- ting up your new system :

•Before making or changing any connections, ALWAYS make sure that the subwoofer and your other components are turned OFF. Also turn down the volume control of the subwoofer and your preampliÞer or receiver.

Tape Deck

•Whenever possible, keep the power cords away from the signal cables or speaker wires to prevent any hum or interference being heard in the speakers.

•Choose reliable, high quality inter- connect cables, also called patch cords or RCA cables. They should be fully shielded and as short as possible for the job. The longest cable in your system will likely be to the subwoofer, so choose a good quality brand.

DVD	• Some patch cords can be a very
	tight Þt and there is usually a
Preamplifier	preferred method of getting them
	off. Some have to be removed with
	a twisting action. Be gentle or you
Power strip	may damage the jacks of the sub-
	woofer or your other components.

AC outlets on the same circuit breaker

Subwoofer

•This diagram shows all the low power components sharing a power strip which is connected to the same outlet used by the ampliÞer.

•The subwoofer is connected to an outlet on the same circuit breaker, provided that the total system current draw does not exceed the breaker current rating.

•This arrangement will reduce the possibility of an audible hum in your system caused by a ground loop.

Speaker Level connections

•The subwoofer’s speaker level inputs can accept speaker wires with banana, dual-banana, bare wire or spade terminals. If you have banana type connectors on your speaker wire, make sure that you tighten the binding posts before inserting.

•Make sure that the negative speaker wires never touch the posi- tive wires as this will short out and possibly damage your ampliÞer or receiver.

The subwoofer’s two negative posts are joined internally (com- mon-grounded). Your ampliÞer must also be internally common- grounded or you cannot use this connection. Contact the manufac- turer of your ampliÞer to make sure its outputs are common grounded.
