1. Before connecting the HEARO 999 AUDIOSPHERE II to your audio source, switch power
to your audio source OFF.

You can connect the HEARO 999 AUDIOSPHERE II to any analog headphones output

coaxial digital output. To connect the transmitter to a coaxial output, use a commercial

When using an analog audio source, check that the DIGITAL switch (2) is OUT. When using
a digital audio source, check that the DIGITAL switch (2) is IN.
You can connect each digital input to a digital audio source and use the DIGITAL IN
switch (17) to toggle between the two audio sources.
1. Switch power to your audio source OFF.
2. Use the supplied AK 1 RCA cables to connect the "TAPE IN", "AUX IN", or
"PLAYBACK IN" jacks on the amplifier to the LINE OUT jacks (15) on the HEARO rear
panel.
3. Refer to the operating manual of your amplifier for instructions on how to listen to and
mute the signal at the TAPE", "AUX", or "PLAYBACK" input. On most amplifiers, you can
push the "TAPE MONITOR" switch IN to listen to the processed signal and OUT to cut
the processed signal.
1. Connect the stereo jack plug on your hardwire stereo headphones to the PHONES
jack (5). You can use the VOLUME control (6) to set the volume of the headphones.
1. Connect the DC cable on the supplied AC adapter to the POWER jack (13) on the HEARO
rear panel.
2. Check that the AC voltage stated on the AC adapter is the same as that avail-
able in your country. If it is, connect the AC adapter to a convenient AC outlet.
Before setting up your system, please remember the following points:
1. Operating switches on or connecting the HEARO 999 AUDIOSPHERE II to your audio
source may cause clicks which at high volume settings may affect your hearing.
Therefore, be sure to set the VOLUME control on the wireless headphones or the
VOLUME control (6) on he HEARO to minimum before switching between different
sources (tuner, turntable, CD player, etc.) or connecting the HEARO.
2. Listening over headphones at high volume levels, particularly over extended periods of
time, may damage your hearing.
3. The transmitter incorporated in your HEARO 999 AUDIOSPHERE II is a radio frequency
device that conforms to the strict European and FCC standards. For physical reasons
that are not related to the quality of the product, extremely strong interference sources
may affect reception. In order to maintain interference-free listening pleasure, do not
operate your HEARO 999 AUDIOSPHERE II in the close vicinity of radio equipment, cel-
