3. FEATURES
• Excellent Sound Quality
Both the built-in cone speaker and constant directivity speaker feature the highest sound quality.
• High Intelligibility
New circuitry has been designed to reduce sound distortion at high-volume sound outputs to realize
excellent intelligibility for both quiet and loud sounds.
• High Power and Long Battery Life
Although rated at a high power output of 20 W, the WA-1822 consumes low power to maintain a longer
battery life.
• Lightweight Design
Carefully reviewed design and construction realize reduced and balanced weight that facilitates transport
and makes the Meeting Amplifier seem lighter than it actually is.
• Improved Operating Ease
· Knobs are easy to operate, and indications are larger and more legible.
· Increased component storage volume is large enough to accommodate 2 wireless microphones, 1 wired
microphone and a dust cover.
· Power cord hanger facilitates storage of bulky power cord.
· Cartridge type battery case facilitates battery replacement.
· Battery check function indicates when batteries should be replaced.
· Snap-in type external speaker terminal facilitates external speaker connection.
4. HINTS FOR BETTER USE
• Positioning Orientation
Position the unit with its front (speaker side) oriented toward the listeners to avoid feedback. If feedback
occurs, move the microphone away from the unit or decrease the output volume.
• Location
Sound from the speaker can be heard more clearly by positioning the unit above floor level, such as on a
desk. The distance between the meeting amplifier and the wireless microphone can also be made longer.
• Dead Point
As the wireless microphone user moves, a point where signal reception is abruptly and temporarily lost may
be encountered due to radio signal reflection or interference. To avoid such a dead point, keep the unit away
from walls or desks, or move the unit location approximately 1 – 2 m in any direction.
• Radio Signal Source Interference
Keep the unit away from fluorescent lamps or computers, which can generate high frequency noise, as radio
interference could result, shortening the wireless microphone's transmission distance.
• Wireless Microphone Distance
Keep the unit at least 3 m away from the wireless microphone. If the distance is shorter than 3 m, feedback
noise can be generated, resulting in radio interference.
• Cleaning
When cleaning, be sure to switch off the power, then wipe with a dry cloth. If the unit should become
extremely dirty over time, use a cloth dampened in a neutral detergent. Never use volatile liquids such as
benzene or thinner, because they can deform or discolor the unit's case.
