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.
