Thank you for purchasing TOA's Wall Mount Speaker.

Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.

• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.

• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.

• After reading, keep this manual handy for future reference.

1. SAFETY PRECAUTIONS

• BS-678 series, of which cabinet is made of wood, can be installed in a vertical or horizontal orientation.

• Either concealed in-wall wiring or open wiring can be used for speaker cable connection.

• The speaker structure that permits direct wall-mounting with screws prevents the speaker from falling easily even if an outward force

is applied to.

• The input impedance can be easily changed by changing the tap position of the transformer.

• Two built-in 6-inch double cone speaker units deliver high quality sound.

• The push-in type input connector makes cable connections easy and allows bridge wiring.

• BS-678T and BS-678BT have a built-in attenuator and can be connected to a 2-wire or 3-wire system.

2. FEATURES

• To avoid electric shocks, be sure to switch off the amplifier's

power when connecting speakers.

• Do not operate the unit for an extended period of time with the

sound distorting. This is an indication of a malfunction, which

in turn can cause heat to generate and result in a fire.

• Do not stand or sit on, nor hang down from the unit as this may

cause it to fall down or drop, resulting in personal injury and/or

property damage.

• Install the unit only in a location that can structurally support

the weight of the unit and the mounting bracket. Doing

otherwise may result in the unit falling down and causing

personal injury and/or property damage.

• Do not use other methods than specified to mount the bracket.

Extreme force is applied to the unit and the unit could fall off,

possibly resulting in personal injuries.

• Tighten each nut and bolt securely. Ensure that the bracket

has no loose joints after installation to prevent accidents that

could result in personal injury.

Step 3. Make wiring.

3-1. Insert the lead-in cables (cables from the amplifier) and

lead-out cables (cables to other speakers) into the

push-in connector attached to the cabinet.

[Applicable

cable]

Solid wire: ø0.8 to ø1.6 mm

(AWG 20 – 14)

Stranded wire (7-core): 0.75 to 1.25 mm

(AWG 18 – 16)

Step 4. Hook 2 V-shaped springs attached to the baffle into the

slotted holes of the cabinet, then push the baffle onto

the cabinet.

Note

When the speaker mounting

orientation is vertical, pinch and

rotate the logo mark on the baffle

into the right position.

3-2. Insert the fasten terminals fitted at the ends of both the

HOT (black) and COM (white) cables from the input

connector on the cabinet into the taps of the matching

transformer on the speaker unit.

Connect the COM (white) cable to the transformer's

COM tap, and the HOT (black) cable to the desired

transformer's input tap. (Refer to the figure below.)

Step 2. Install the cabinet to the wall using the supplied tapping

screws 4 x 35. In this case, route the cables from a

cable entry hole.

Note

The speaker can be installed in a vertical or horizontal

orientation. Either concealed in-wall wiring or open

wiring are available for speaker cable connection.

3. INSTALLATION

Step 1. Pull out the baffle, unlatch 2 V-shaped springs, then

remove the baffle from the cabinet.
