WARNING

Indicates a potentially hazardous situation which,

if mishandled, could result in moderate or minor

personal injury, and/or property damage.

CAUTION

1. SAFETY PRECAUTIONS

•

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.

• As a force of approx. 18 kg (39.68 lb) is applied to the

speaker receptacle at the time of speaker installation,

attach it in a location durable enough to withstand the

force. Doing otherwise may result in the unit falling

down, causing personal injury.

• 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.

• Use nuts and bolts that are appropriate for the wall's

structure and composition. Failure to do so may cause

the speaker to fall, resulting in material damage and

possible personal injury.

• Ensure that all screws are securely tightened. If they

are loose after installation, the unit could fall down,

possibly resulting in personal injury.

• 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.

• Thin type wall mount speaker with 5" cone speaker unit

• Two-way speaker system employing a balanced dome

tweeter and elliptical horn for high-frequency sound

reproduction in combination with a 5" cone speaker

unit ensures high-quality sound. (BS-1034 and BS-

1034S)

• The speaker's smoothly curved surface in combination

with its straight lines permits it to blend in with virtually

all modern buildings.

• Equipped with a speaker receptacle, providing speaker

cable connection and installation ease.

• Equipped with a lock mechanism, preventing the

speaker from being detached easily after installation.

• In-wall wiring, exposed wiring, or bridge wiring

available for speaker cable connection

• The input power (impedance) can be easily changed

by the rear-mounted rotary switch. (BS-1034 and BS-

1034S)

• The BS-634T has a built-in attenuator and can be

connected to a 3-wire and 2-wire systems.

Step 1. Attach the speaker receptacle to a wall.

[Notes on horizontal speaker mounting]

• Even if the speaker receptacle is attached horizontally,

the speaker may be tilted due to its weight unbalance

when attached to the receptacle.

• Be sure to attach the speaker so that its volume control

is positioned downward. (BS-634T only)

• When changing the logo direction, peel off the logo

carefully as it is affixed using double-faced tape. Then,

re-affix it in the right orientation.

[Exposed wiring]

Notch the top of the speaker receptacle using long-nose

pliers, then make connections.

If the supplied tapping screws are not appropriate for the

construction of wall, separately prepare the appropriate

screws.

Install the speaker receptacle referring to its "UP" mark.

Position the receptacle at the specified distance away from

any object above and below it for vertical speaker mounting.

Keep the same distance to the right and left of the receptacle

(positioned sideways) for horizontal speaker mounting.
