Thank you for purchasing TOA's Ceiling 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.
WARNING
Indicates a potentially hazardous situation
which, if mishandled, could result in death or
serious personal injury.
• 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.
• Since the unit is designed for in-door use, do not
install it outdoors. If installed outdoors, the aging of
parts causes the unit to fall off, resulting in personal
injury. Also, when it gets wet with rain, there is a
danger of electric shock.
• 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.
CAUTION
Indicates a potentially hazardous situation
which, if mishandled, could result in moderate
or minor personal injury, and/or property
damage.
• Avoid touching the unit's sharp metal edge to
prevent 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.

3. GENERAL DESCRIPTION
Integrated with a resin panel and speaker frame, the
PC-648R and PC-658R are the ceiling mount
speakers with a metal grille attached.
They feature spring clamp mechanism for easy
speaker mounting to the ceiling.
The input impedance can be easily changed by
changing the tap position of the transformer.
3-2. Change the input impedance as needed.
The speaker's input is factory-preset to 1.7
kΩ.
When changing the input impedance, detach
the black wire connected to the matching
transformer, and reinsert it into the desired
input tap referring to the table below.
