CAUTION:
If the "AMPLIFIER" and "SPEAKERS" connections are reversed, a short could result across the amplifier or receiver
output terminals, which may seriously damage your amplifier or receiver. Please double-check all connections before turning
on your amplifier or receiver.
Labeling the front of the Speaker Selector (Figure #4)
There is one set of adhesive labels included to be used on the front of the Speaker Selector. These labels make it easy to iden-
tify which area has been selected when the button is depressed. There are indentations above each button on the front of
the Selector. Place the appropriate area label into each of these locations. If you can't find the label you need, you can create
your own by writing on one of the blank labels using a pen or small marker.

OPERATION
Understanding the Protection Circuit
To prevent damage to your amplifier or receiver, the S4dc and S8dc feature protection circuitry.
When engaged, the protection features prevent damage from occurring to your amplifier or receiver.
When to Use the Front Mounted Protection Switch
The front Protection switch (Figure #5) should be engaged under the following
circumstances to best protect your amplifier or receiver. The switch is "ON" when
depressed:
Speakers Selected Front Protection Button
1 or 2 pair of 8 ohm speakers OFF
3 or more pairs of 8 ohm speakers ON
1 pair of 4 ohm speakers OFF
2 or more pairs of 4 ohm speakers ON
A combination of 4 and 8 ohm speakers ON
When to Use the Rear Mounted Protection Switch
On the back of the selector there is a slide switch labeled "Continuous Protection"
(Figure #6). When this button is in the "ON" position, it will override the front
Protection button and assure that the protection circuitry is always on, no matter
what the position of the front button.
This switch should be placed in the "ON" position if you are concerned that some-
one unfamiliar with the system may fail to properly use the front protection button.
Selecting Speakers
To turn on a pair of speakers, simply depress the button associated with that pair. Please take precautions to make sure that
the amplifier volume is not set at a high level before you depress the button.

Connecting Wires to the Speaker Selector
CAUTION:
Please make sure your amplifier or receiver is turned off before proceeding.
Direct Connect features removable terminal connectors, which simplify connecting the speaker and amplifier wires to the
Speaker Selector. (See Figure #2)
For best results, use speaker wire that is at least 18 gauge. For runs longer than 75 feet, 14 gauge wire is recommended.
Wire larger than 14 gauge is not recommended because it may not fit into the connector. For best results, strip all wire insu-
lation no more than 3/8" from the end before inserting into the connector.
1. Pull the Direct Connect terminal from its location on the back of the cabinet. This will make it easier to connect the wires.
(Figure #3)
2. Connect the wires from the speakers to the appropriate location under "SPEAKERS" on the removable terminals. Please
observe proper polarity (+, -) of the connections. (Figure #3)
3. Connect the amplifier's or receiver's speaker outputs to the appropriate location under "AMPLIFIER” on the removable ter-
minal. Please observe proper polarity (+, -) of the connections. (Figure #3)
