To connect FM and AM antennae

G68 Digital Surround Controller

FM AM

•Connect an FM antenna or split-flex dipole to the FM Coax connector, if necessary using the adaptor provided.

In the UK use a female Belling-Lee (VCR) connector.

Although the FM tuner is very sensitive, the FM antenna is supplied for basic installation only, and for best performance and lowest noise use a high-quality antenna placed as high as possible and oriented towards the transmitter.

Note: For all outdoor antennae we strongly recommend you use a qualified installer who will comply with local safety regulations.

•Connect an AM antenna to the AM connector by pressing the tabs and inserting a bare wire into each hole. The ground connection (black on the supplied AM antenna) should be connected to the socket marked GND.

The product is supplied with an indoor loop antenna. This is directional, and for best results you will need to orient it, and this may be station dependent.

•Place the antenna as far away from other electrical equipment and as high as possible.

For best AM results use an external AM antenna.

Note: For AM you must fit a good ground as well as an antenna.

The tuner can be used with most proprietary indoor AM, FM, or combi (AM/FM) antennae. It is possible in some cases to use a trigger output (+12V) from the G68 to power such devices.
