noise, and exceptional interference rejection. The IVA processor and the Dolby Surround
Pro-Logic decoder provide optimum spatial reproduction for speech, music, TV and video
sound, multimedia PC applications, and video games.
In order to make optimum use of the benefits of your HEARO 888 TITAN, please take a few
minutes to read the instructions below carefully
before operating the equipment
.

You can operate your transmitter with several digital headphones simultaneously. Make sure
to use digital wireless headphones operating in the same UHF frequency band as the
HEARO 888 TITAN.
One drawback of headphone listening is the psychoacoustic phenomenon of “inside local-
ization”: the orchestra seems to play inside your head rather than in the room. AKG de-
veloped a binaural audio processing techniquecalled IVA (Individual Virtual Acoustics) that
models the way the head and pinnae change the arriving sound waves (ear matching
function). Thus, the various sound sources will seem to be located outside your head even
when you are using headphones.
A: Natural hearing: Due to the effect of the head and
pinnae, sound waves arriving at one ear differ from
those arriving at the other. Amplitude and phase
differences create a sense of spatial hearing.
B: Listening through headphones: Amplitude and phase
differences are eliminated. Sound sources are local-
ized inside the head rather than in the room.
