Connecting the

F-12 to a wall plug

The subwoofer draws a moderately high

amount of current. We do not recommend

plugging it into a "convenience" outlet

(switched or unswitched) that is often

found on the back of receivers and other

stereo components.

Instead, connect the F-12 to its own AC

outlet ONLY. See items 8 and 9 in the Safety

Instructions.

SUBWOOFER

CONNECTION

Method A: Line level

hookup steps for receivers

with subwoofer connections

See Drawing 3 below

Note: This connection method is only

for receivers that have a subwoofer or

LFE output. If your receiver does not

have a subwoofer or LFE connection as

shown in Drawing 3, use Method B:

Amplifier wiring hookup steps for

receivers or surround sound receivers

with NO sub output jack. You will need

one line level RCA to RCA connector cable

long enough to reach from your receiver

to your subwoofer location. This should

be available from your B . I . C/Formula

dealer or from radio supply stores.

1. IMPORTANT: Make sure that ALL

stereo system components including

the subwoofer are turned OFF before

proceeding.

2. Locate the subwoofer or LFE output

connector on the rear of your receiver

and connect one end of the RCA line level

cord to it.

3. Route the line cord to the subwoofer

location (trying to minimize areas where it

may be stepped on) and connect the other

end directly to the SUB IN.

4. Connect your main (and surround

speakers if applicable) to the receiver

according to the receiver's owner's manual.

5. Set the RECEIVER TYPE toggle

switch to the type of receiver you have.

Note: If you are using a Dolby Digital

type receiver, the subwoofer crossover

control does not work. You must set

the crossover frequency in your

receiver (check your receiver's

owner's manual).

6. You are now ready to put your

subwoofer into use.

Converting Subwoofer to 220-240 Volt Operation

Remove amplifier from subwoofer cabinet. Take out all the screws around the perimeter

of the control plate. Lift out the amplifier, reaching into the cabinet to remove the wire clip

leads from the woofer input terminals.

Locate the power supply voltage-setting connectors. They're on the PC board that's

attached between the aluminum heat sinks. At one end of the board the red and black AC

power lines are attached. On that end, on the lower right-hand corner, you'll see two small

jumper connectors.

Move the connectors. There are four pairs of pins onto which the jumpers can be placed.

For 120-volt operation the jumpers are placed on the two outer pairs of pins. To set up the

amplifier for 220-240 volt input, pull the jumpers straight up off the outer pin pairs and place

them on the inner pairs of pins. (Sometimes the jumpers are held in place with hard yellow

gunk. If they are, carefully cut through the gunk with an X-ACTO knife to free the jumpers.)

Replace the amplifier into cabinet. Reattach the wires to the woofer input terminals.

Orient the amplifier control plate as it was originally, drop it in position, and replace the

screws around the perimeter.
