you may have connected to the HEARO 999 AUDIOSPHERE II. The IVA-PHONES
and VMAx LEDs extinguish.
A Dolby Digital encoded signal present at the input will be automatically mixed down
to a Pro-Logic encoded stereo signal.
VMAx: The VMAx processor derives a 3-D signal for loudspeaker reproduction. In VMAx
mode, the green LED above the VMAx label will be illuminated.
In all modes, the same signal will be available at all outputs (PHONES, LINE OUT, built-in
transmitter).
10. EARS: The shape of the outer ear changes the waveform of impinging sound in a unique
way that differs from person to person. Using headphones defeats these outer ear trans-
fer functions because the sound sources are located immediately in front of the ears. The
result is unnatural sound.
In order to provide the most realistic headphone reproduction possible, AKG measured
many outer ear transfer functions and electronically modeled seven representative "ear
curves".
In IVA-PHONES mode, the EARS selector offers a choice of one standard ear curve ("N")
and six other ear curves for you to select the one that sounds the most natural to you. In
DIRECT and VMAx modes, the EARS selector is disabled.
11. SOUND: In IVA-PHONES mode, this 12-step rotary switch lets you select four different
sound programs, each with three speaker spreader settings (close, medium, or wide vir-
tual stereo spread):
NORM: Basic sound program for all types of program material.
MUSIC: Linear response for a neutral sound rich in detail.
VOICE: This sound program has been optimized for intelligibility of speech and is there-
fore recommended for radio and TV programs with a high proportion of speech, or
for monitoring during speech and vocal recording sessions in the studio.
MOVIE: Simulates the typical sound of theater speakers and is therefore recommended
for videos and DVD movies in Dolby Surround or Dolby Digital formats.
In VMAx mode, only the speaker spreader function without the sound programs will be
available.
12. DYNAMIC: The dynamic range (the difference between the loudest and softest pas-
sages) of Dolby Digital encoded input signals may sometimes be so great that soft
dialogs may become unintelligible.
With the DYNAMIC switch IN, the dynamic range is reduced. This means that very soft
passages will automatically be raised in level while very loud passages are attenuated so
the average perceived loudness of the signal rises. The green LED next to the switch is lit.
With the DYNAMIC switch OUT, the full dynamic range of the input signal is preserved
and the green LED next to the switch extinguishes. The difference between the loudest
and softest passages is the same as in the original signal.

13. POWER: Input jack for the AC adapter.
14. LINE IN LEFT/RIGHT: RCA audio input jacks for analog stereo or Pro-Logic encoded
signals.
15. LINE OUT LEFT/RIGHT: Analog RCA audio output jacks. The output level depends on
the setting of the INPUT control (3). The VOLUME control (6) does not affect the output
level.
16. COAXIAL: RCA input jack for an optional coaxial cable for interfacing with a digital audio
source with a coaxial output.
17. DIGITAL IN: Pushbutton switch that activates either the coaxial or the optical digital
input.
18. OPTICAL: Input connector for the supplied fiber optical cable for interfacing with a
digital audio source with an optical output.
19. ANT: Flexible, swiveling UHF transmitting antenna.
