Location
Before moving the device, remove all connected cables.
When transporting or moving the device, always use two or more
people. Attempting to lift the device by yourself may damage your
back, result in other injury, or cause damage to the device itself.
When setting up the device, make sure that the AC outlet you are
using is easily accessible. If some trouble or malfunction occurs,
immediately turn off the power switch and disconnect the plug from
the outlet.
Do not use the device in a confined, poorly-ventilated location. Make
sure that there is adequate space between the mixer and
surrounding walls or other devices: at least 30 cm at the side, 30 cm
behind and 30 cm above. If the mixer is to be used installed into the
speaker cabinet, make sure to allow adequate space between the
speaker and the surrounding walls or other devices: at least 30 cm at
the sides, 30 cm behind and 30 cm above. Inadequate ventilation can
result in overheating, possibly causing damage to the device(s), or
even fire.
Do not use the speaker’s handles for suspended installation. Doing
so cam result in damage or injury.
Avoid setting all equalizer controls and faders to their maximum.
Depending on the condition of the connected devices, doing so may
cause feedback and may damage the speakers.
Do not expose the device to excessive dust or vibrations, or extreme
cold or heat (such as in direct sunlight, near a heater, or in a car
during the day) to prevent the possibility of panel disfiguration or
damage to the internal components.
Do not place the device in an unstable position where it might
accidentally fall over.
Do not block the vents. This mixer has ventilation holes at the top to
prevent the internal temperature from becoming too high. In
particular, do not place the device on its side or upside down.
Inadequate ventilation can result in overheating, possibly causing
damage to the device(s), or even fire.
Do not use the device in the vicinity of a TV, radio, stereo equipment,
mobile phone, or other electric devices. Doing so may result in noise,
both in the device itself and in the TV or radio next to it.
Handing caution
When turning on the AC power in your audio system, always turn on
the device LAST, to avoid speaker damage. When turning the power
off, the device should be turned off FIRST for the same reason.
Do not insert your fingers or hands in any gaps or openings on the
device (vents, ports, etc.).
Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.)
into any gaps or openings on the device (vents, ports, etc.). If this
happens, turn off the power immediately and unplug the power cord
from the AC outlet. Then have the device inspected by qualified
Sound Barrier service personnel.
Do not use the device for a long period of time at a high or
uncomfortable volume level, since this can cause permanent hearing
loss. If you experience any hearing loss or ringing in the ears, consult
a physician.
Do not operate the device if the sound is distorting. Prolonged use in
this condition could cause overheating and result in fire.
Do not rest your weight on the device or place heavy objects on it,
and avoid use excessive force on the buttons, switches or
connectors.
Protective Circuit (poly switch)
All full-range loudspeakers are fitted with a self-resetting poly switch
that protects the high-frequency diver from damage caused by
excessive power. If a loudspeaker cabinet loses high-frequency
output, immediately remove power from the unit and wait for two to
three minutes. This should be long enough to allow the poly switch to
reset. Reapply power and check the performance of the high
frequency driver before continuing, with the power reduced to a level
that does not cause the poly switch to interrupt the signal.
Interference From Cell Phone
Using a cell phone near the speaker system can induce noise. If this
occurs, move the cell phone further away from the speaker system.
Air blowing out of the bass reflex ports is normal, and often occurs
when the speaker is handing program material with heavy bass
content.
Sound Barrier cannot be held responsible for damage caused by improper use
or modification to the device.
Always turn the power off when the device is not in use.
The performance of components with moving contacts, such as
switches, volume controls, and connectors, deteriorates over time.
Consult qualified Sound Barrier service personnel about replacing
defective components.
