Toa PJ-304 - Manual

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.
• 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 all screws securely. If any is loosely fixed, this
may cause the unit to fall, resulting in personal 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.
• Do not hang down from the unit as this may cause it to
fall down or drop, resulting in personal injury and/or
property damage.
The PJ-64 and PJ-304 are projection speakers designed
for ceiling and wall installations. Considered in
architectural design, they can blend in with lighting
equipment.
The supplied swivel bracket allows for flexible speaker
angle adjustment.
The PJ-64 is driven on high-impedance (100 V and 70 V)
line, while the PJ-304 is driven on both high-impedance
(100 V and 70 V) and low-impedance (8 Ω) lines.
The input power (impedance) can be easily changed at
the upper side of the speaker.
The speakers are easy to repaint so as to meet a wide
range of design needs
