4.
Replace the ear pad on the earphone aligning the four pins on the ear pad with the
matching openings in the earphone base plate.
1.
Remove the headphones from the transmitter.
2.
Switch ON the audio source to which the transmitter is connected.
3.
Slide the OFF/ON switch (8) on the transmitter to ON to switch the transmitter on. All
front panel LEDs will flash momentarily.
Note that the transmitter will not switch on until it detects an audio signal at the
INPUT L/R jacks (15).
If audio signal is present at the transmitter input, the CHARGE LED (7) on the trans-
mitter will light green.
If no signal arrives at the transmitter input for approx. 3 minutes, the transmitter will
automatically switch off and the CHARGE LED (11 will extinguish.
4.
Use the INPUT LEVEL control (19) on the transmitter rear panel to set the input level
so that the front panel INPUT LEVEL LED (9) will light green intermittently or constantly
and flash red only on the loudest signal peaks.
5.
Use the POWER switch (1) to switch the headphones ON. The green POWER LED (2)
will light.
6.
Set the TUNING control (5) on the headphones such that you will hear the signal in the
headphones clearly and free of interference.
If the signal remains weak or noisy, use the FREQ. ADJUST control (18) on the trans-
mitter to select a different carrier frequency and set the TUNING control (5) again as
described above.
Be sure not to rotate FREQ. ADJUST (18) all the way CW or CCW because optimum
reception may not always be guaranteed at the ends of the frequency band.
7.
Set the VOLUME control (6) on the headphones to the desired volume level.
Beep sounds audible in the headphones mean that the received signal is too weak, the
headphones receive no signal, or that the headphones are tuned to a different fre-
quency than the transmitter. Move closer to the transmitter or repeat step 6 above..
The mode switch (13) lets you select the desired reproduction modes of your
HEARO 888 TITAN.
The mode switch (13) has three positions:
Left: STEREO
for standard stereo reproduction. The input signal is transmitted un-
changed.
In stereo mode the green STEREO LED (10) will light.
We recommend STEREO mode for stereo music and speech reproduction.
Center: IVA STEREO.
The IVA processor converts the stereo input signal to a binaural
signal. The ear matching function provides a natural sonic perspective with no inside
localization.
In IVA stereo mode the green IVA STEREO LED (11) will light.
We recommend IVA STEREO mode for 3-D music and speech listening.
Right: IVA SURROUND.
The Dolby Surround Pro-Logic Decoder, in conjunction with the
IVA processor, simulates five loudspeaker channels (front left, center, right and rear left
and right) for surround sound in the headphones.
In IVA SURROUND mode the green IVA SURROUND LED (12) will light.
We recommend IVA SURROUND mode for radio drama, TV, PC applications, video,
surround sound and pop music recordings.
The PANORAMA switch (14) allows you to change the apparent stereo base of the loud-
speakers simulated by IVA processing.
1.
Position “N” is the factory programmed default setting of the simulated stereo base.
2.
To decrease the stereo base, set the PANORAMA switch (14) to “1”.
3.
To widen the stereo base, set the PANORAMA switch (14) to “2”.
