1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section
carefully before use.

• Make sure to observe the instructions in this
manual as the conventions of safety symbols and
messages regarded as very important precautions
are included.

• We also recommend you keep this instruction
manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages described below are
used in this manual to prevent bodily injury and
property damage which could result from
mishandling. Before operating your product, read this
manual first so you are thoroughly aware of the
potential safety hazards as well as understand the
safety symbols and messages.

• Install the speaker only in a location that can
structurally support the weight of the speaker and
the mounting bracket. Doing otherwise may result
in the speaker falling down and causing personal
injury and/or property damage.

• Be sure to attach the supplied safety bracket after
mounting the speaker to the mounting bracket.
Failure to attach the safety bracket may cause the
speaker to drop, resulting in personal injuries.

• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property
damage.

• Do not operate the speaker 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.

2. GENERAL DESCRIPTION

Designed with an emphasis on the sound quality, TOA's corner speaker system can be cleanly mounted in the
corner of the room. The speaker system is small in size yet enhances the low frequencies to reproduce rich
sound when installed in the corner. It can be mounted in the room corner, ceiling, and wall using the
supplied mounting bracket. Its ideal applications include stores and assembly halls.

3. MOUNTING THE BRACKET

• Attach the supplied bracket to a heavy-duty wall, ceiling or room corner to withstand a load of the unit and
bracket.

• When only one of the two walls of the corner can be used, attach the bracket's larger plate (having four
mounting holes) to that wall.

Note: No mounting screws are supplied with the unit. Use screws suited to materials of the wall or ceiling.

4. CONNECTIONS

4.1. High Impedance (100 V Line) Connection

• One out of 1 kΩ (10 W), 2 kΩ (5 W), and 3.3 kΩ (3 W) input
terminals can be selected.

• Connect the selected terminal and COM terminal to an
amplifier.

4.2. Low Impedance (8 Ω) Connection

Terminals are provided for high impedance operation when the
speaker system is supplied from the factory. When making low
impedance connections, change internal wiring by following
the procedures below:

1. Remove the punched grille (see the figure at right).

2. Remove the speaker element.

3. Disconnect cables (black and red) between the matching

transformer and speaker element at the speaker element.

Note

To prevent the terminals of the disconnected cables from contacting other terminals, wrap the insulation tape
round the terminals or cut them off from the disconnected cables.
