PRECAUTIONS
PLEASE READ CAREFULLY BEFORE
PROCEEDING
Please keep this manual in a safe place for
future reference.
WARNING
Always follow the basic precautions listed
below to avoid the possibility of serious
injury or even death from electrical shock,
short-circuiting, damages, fire or other
hazards. These precautions include, but
are not limited to, the following:
Fire warning
• Do not place any burning items or open
flames near the product, since they may
cause a fire.
Hearing loss
• Before turning the power of all devices on or

to the minimum. Failing to do so may result
in hearing loss, electric shock, or device
damage.
• When turning on the AC power in your
audio system, always turn on the power
amplifier LAST, to avoid hearing loss and
speaker damage. When turning the power
off, the power amplifier should be turned off
FIRST for the same reason.

injector or the PoE network switch, use a
CAT5e or higher LAN cable, which supports
the maximum power supply voltage (57 V)
of the IEEE 802.3at standard. If you connect
a cable that does not comply with
specifications, or connect a flat type or slim
type cable, fire or malfunctions might occur.
• Do not damage the LAN cable. Failure to
observe this precaution could result in fire,
electric shock, or damage to the product.
- Do not place heavy objects on the cable.
- Do not process the cable in any way.

poorly-ventilated location.
Inadequate ventilation can result in
overheating, possibly causing damage to
the product(s), or even fire.

Installation
For recessing into the ceiling, refer to the procedure on the back page.
WARNING:
• Before installing, confirm that the locations where the unit and the safety wire are to be installed are strong enough.
• For the following work, use a safety wire, and be careful not to fall or cause the unit or surrounding structures to be dropped
or damaged.
NOTICE:
• To supply power, confirm that the unit is securely installed, and then connect the LAN cable to a PoE injector or PoE network switch that
complies with IEEE802.3af.
• Cables up to a maximum length of 100 m can be used.
• In order to prevent electromagnetic interference, use STP (shielded twisted pair) cables.
When using a VESA mounting bracket for
ceiling mounting
Prepare a VESA100-compatible mounting bracket and mounting
screws.
For details on attaching the VESA mounting bracket, refer to its
manual. The following is an example.
If the terminal cover will not be used, skip steps
1 and 2–1, 8
and
10
on the back side. However, the dustproofness and plenum
ratings will not be met.
1. Make a hole in the terminal cover to pass the conduit
through.
Make a cable hole in the terminal cover according to the
orientation of the conduit. The cable hole can be made in the
terminal cover horizontally or vertically.
We recommend using nippers. The terminal cover may
become deformed if you try to make the hole by hitting or
prying the cover with a flathead screwdriver, etc.
2. Attach the VESA mounting bracket to the unit by
using the screw holes shown below.
3. Attach the VESA mounting bracket to the ceiling.
For the remainder of the procedure, continue with steps 2–6 to
2–
10
and step 4 on the back side.
When hanging with wires
Prepare wires and eyebolts (M6 × 13 mm or less) with sufficient
load capacity for hanging.
NOTE:
Use eyebolts that meet local regulations and safety standards.
NOTICE:
The strength of an eyebolt depends on its installation angle. Install
an eyebolt within a range of 0° to 45° from vertical.
If the terminal cover will not be used, skip steps 1 and 2–1, 8
and
10
on the back side. However, the dustproofness and plenum
ratings will not be met.
1. Make a hole in the terminal cover to pass the conduit
through.
Make a cable hole in the terminal cover according to the
orientation of the conduit. The cable hole can be made in the
terminal cover horizontally or vertically.
We recommend using nippers. The terminal cover may
become deformed if you try to make the hole by hitting or
prying the cover with a flathead screwdriver, etc.
2. Install the eyebolts into the unit by using the screw
holes shown below.
3. Install the unit by attaching it to the wires hanging
from the ceiling, making sure that the unit is
horizontal.
For the remainder of the procedure, continue with steps 2–6 to
2–
10
and step 4 on the back side.
