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.

Please keep the manual for future reference.

The HEARO 888 TITAN headphone system

• uses state-of-the-art UHF radio transmission technology;
• uses digital signal transmission for minimum noise, wider dynamic range, better high-frequency reproduction, lower distortion, and better interference rejection.
• connects to any audio, video, TV set, or PC with a headphones or line output;

2.2 IVA - Individual Virtual Acoustics

One drawback of headphone listening is the psychoacoustic phenomenon of "inside localization": the orchestra seems to play inside your head rather than in the room. AKG developed a binaural audio processing technique called 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 localized inside the head rather than in the room.

C: Listening through headphones with IVA processing: The ear matching function modifies the audio signals at the ears to resemble diagram A. This restores natural, spatial hearing.

The Dolby Surround Pro-Logic decoder integrated in the transmitter uses the stereo input signal to derive two additional signals, a center and a surround channel. The IVA circuitry generates from these signals a binaural signal equivalent to reproduction through five high quality loudspeakers (3 front, 2 rear speakers). This allows you to enjoy all the benefits of Dolby surround sound even through headphones.

2.3 Dolby Surround Pro-Logic Decoder

Your headphones system comprises the following components:

1 pair of headphones
1 transmitter with integrated battery charger
2 stereo connecting cables with gold plated connectors for linking the transmitter to your audio source: 1 RCA cable, 1 jack cable (mini jack to 2 x RCA connectors)
