Connect the SPK 800 Speaker to the R800 Receiver using the black speaker cable
provided. (See Figure 6) Pull apart the two strands as necessary. Observe that one
strand’s insulation is furrowed or ridged, while the other is smooth.
To make the connection, press the connector buttons on both the speaker and receiver,
inserting the furrowed or ridged wire into the red connector on both the R800 and
SPK 800. After the wire has been inserted, release the button and tug lightly to make
sure the cable has been secured.
4.
Set the volume on the R800 below the level at which feedback occurs.
If you need more cable, contact Williams Sound or visit your local electronic parts store.
