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.

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.

2. FEATURES

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 BS1034S)

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 BS1034S)

The BS-634T has a built-in attenuator and can be connected to a 3-wire and 2-wire systems.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

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.

CAUTION

Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

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.

(3.29")

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.

[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.

Split the speaker cable into 2 branches just before it enters the speaker receptacle so that it can be routed in the cable-guide groove on the rear side of the speaker.
