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.
Indicates a potentially hazardous situation which,
if mishandled, could result in death or serious
personal injury.
WARNING
• 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.
• Since the speaker is designed for indoor use, do
not install it outdoors. If installed outdoors, the aging
of parts causes the speaker 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speciedtomount
the bracket. Extreme force is applied to the speaker
and the speaker could fall off, possibly resulting in
personal injuries.
Indicates a potentially hazardous situation which,
if mishandled, could result in moderate or minor
personal injury, and/or property damage.
CAUTION
• Avoidtouchingthespeaker’ssharpmetaledgeto
prevent injury.
• To avoid electric shocks, be sure to switch off the
amplier’spowerwhenconnectingspeakers.
• 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.

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.
4. INSTALLATION
Step 1. Using the supplied paper pattern as a guide,
open a mounting hole of the dimension
speciedbelowintheceiling.
