Warnings
•
Do not allow water to enter this unit or allow the unit to
become wet. Fire or electrical shock may result.
•
Connect this unit’s power cord only to an AC outlet of the
type stated in this Owner’s Manual or as marked on the unit.
Failure to do so is a fire and electrical shock hazard.
•
Do not scratch, bend, twist, pull, or heat the power cord. A
damaged power cord is a fire and electrical shock hazard.
•
Do not place heavy objects, including this unit, on top of the
power cord. A damaged power cord is a fire and electrical
shock hazard. In particular, be careful not to place heavy
objects on a power cord covered by a carpet.
•
If you notice any abnormality, such as smoke, odor, or
noise, or if a foreign object or liquid gets inside the unit,
turn it off immediately. Remove the power cord from the
AC outlet. Consult your dealer for repair. Using the unit in
this condition is a fire and electrical shock hazard.
•
Should this unit/AC adapter/power supply be dropped or the
cabinet be damaged, turn the power switch off, remove the
power plug from the AC outlet, and contact your dealer. If
you continue using the unit without heeding this instruction,
fire or electrical shock may result.
•
If the power cord is damaged (i.e., cut or a bare wire is
exposed), ask your dealer for a replacement. Using the unit
with a damaged power cord is a fire and electrical shock
hazard.
•
Do not remove the unit’s cover. You could receive an
electrical shock. If you think internal inspection, mainte-
nance, or repair is necessary, contact your dealer.
•
Do not modify the unit. Doing so is a fire and electrical
shock hazard.
Cautions
•
When rack-mounting the unit, allow enough free space
around the unit for normal ventilation. This should be: 10
cm at the sides, 30 cm behind, and 20 cm above.
For normal ventilation during use, remove the rear of the
rack or open a ventilation hole.
If the airflow is not adequate, the unit will heat up inside and
may cause a fire.
•
To mount several of these units in an EIA-compliant rack,
refer to the rack mounting instructions on page 8.
•
This unit has ventilation holes at the (top, bottom, front,
rear, and sides) to prevent the internal temperature rising too
high. Do not block them. Blocked ventilation holes are a fire
hazard.
•
Clean the contacts of the phone plug before connecting it to
the SPEAKERS jack of this unit. Dirty contacts may
generate heat.
•
Use only speaker cables when connecting speakers to
amplifier outputs. Using other types of cables is a fire
hazard.
•
Hold the power cord plug when disconnecting it from an AC
outlet. Never pull the cord. A damaged power cord is a
potential fire and electrical shock hazard.
•
Do not touch the power plug with wet hands. Doing so is a
potential electrical shock hazard.
•
Do not use this amplifier for any purpose other than driving
loudspeakers.
Usage
•
Using a mobile telephone near this unit may induce noise. If
noise occurs, use the telephone away from the unit.
•
XLR-type connectors are wired as follows: pin 1: ground,
pin 2: hot (+), and pin 3: cold (–).
