designated.
To avoid oscillation, keep the input cable away from the output cable. Particular care
must be exercised when mounting the unit in an equipment rack.
In some installations, a ground loop is formed and hum noise may be generated. In
such cases, connecting the rear-mounted signal earth terminal to the body of
connected equipment (BGM sound source, expansion amplifier, etc.) may reduce it.
Never connect two amplifier outputs in parallel under any circumstances.
Never connect the AC power cord to any other line voltage than that specifically
2. HANDLING PRECAUTIONS
HBA-1060A/ - 1120A / -1240A
To clean, be sure to switch off the power supply to the unit first, then wipe with a dry cloth.
When the unit gets very dirty, use a cloth damped in a neutral cleanser. Never use
benzene, thinner or chemically-treated cleaning cloth because such volatile liquids could
deform or discolor the unit.
HBA-3240A/HBA-3240E/HBA-3240V/HBA-3480A/HBA-3480E/HBA-3480V
Never move the unit from one place to another with the Flash Card inserted because the
CompactFlash card may fail.
Avoid inserting or withdrawing the CompactFlash card while the unit is in use.
3. INSTALLATION PRECAUTIONS
Do not install the unit in locations exposed to the direct sunlight or heaters, as
the unit could be deformed or discolored.
Avoid installing or storing the unit in dusty or humid locations, as doing otherwise
could cause the unit's failure.
Keep the unit as far away as possible from a fluorescent lamp, digital equipment,
PC or other equipment which generate high frequency noise.
HBA-1060A/ - 1120A / -1240A
HBA-1060A/ - 1120A / -1240A
Do not block the ventilation slots on the upper, right and left, and rear sides to allow
inside heat radiation.
Keep at least 50 mm space from the unit's right and left sides for heat radiation.
