Down-mixing
This is a process of remixing the multi-channel audio (surround sound) on some discs into two
channels. When you want to listen to the audio on a DVD with a 5.1 channel digital surround track
through your television speakers, the down-mixed audio will be output.
Some DVD-Audio prevent down-mixing of all or part of their contents. When playing such discs, or
such parts of the disc, unless the number of connected speakers is the same as the disc’s channel
specification, audio will not be output properly.
MPEG4
A compression system for use on mobile devices or a network, that allows highly efficient recording at
a low bit rate.
Sampling frequency
Sampling is the process of converting the heights of sound wave (analog signal) samples taken at set
periods into digits (digital encoding). Sampling frequency is the number of samples taken per second,
so larger numbers mean more faithful reproduction of the original sound.
No sound from the unit’s
speakers.
Turn off the FM transmitter. (The button changes from orange to
green.) (23)

equipment on an airplane or in a hospital.
Please obey the rules and/or instructions indicated by the hospital or airline.

Can I connect with a
computer?
You can enjoy use of the computer as a television monitor when
connecting with the AV input terminal on a computer. However,
you cannot operate this unit as peripheral equipment.
Do not play your headphones or earphones at a high volume. Hearing experts advise against
continuous extended play.
If you experience a ringing in your ears, reduce volume or discontinue use.
Do not use while operating a motorized vehicle. It may create a traffic hazard and is illegal in many areas.
You should use extreme caution or temporarily discontinue use in potentially hazardous
situations.
Even if your headphones or earphones are the open-air type designed to let you hear outside
sounds, don’t turn up the volume so high that you can’t hear what’s around you.
Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of
sound. So what sounds “normal” can actually be loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
≥
Start your volume control at a low setting.
≥
Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established a comfortable sound level:
≥
Leave it there.
