a conventional multi-channel speaker set-up.The latest digital signal  
processing technology is being used to ensure that you can indulge yourself  
in an overwhelming private home entertainment experience.  
And all this at the volume level that you personally prefer without running  
the risk of disturbing the neighbours or the family!  
To ensure you get the best performance from your digital headphone  
system please read this manual carefully.  
System configuration  
The HP 1500 system consists of a digital base station and a pure  
Hifi headphone.The base station contains a digital signal processor offering  
you a real 5.1-channel surround sound experience through the personal  
comfort of your headphone.  
The base station can decode Dolby Pro Logic II signals as well as  
Dolby Digital and DTS signals.The Dolby Headphone technology will  
ensure that these signals are converted to audio signals that can be handled  
by the headphone whilst still maintaining the directional information as in  
the original signals.  
The base station has an analogue stereo input as well as a digital electrical  
coaxial S/PDIF input.The digital input allows you to enjoy your favourite  
DVD movies in full surround sound through Dolby Pro Logic II,  
Dolby Digital or DTS. And the analogue input brings your collection of  
VCR tapes back to life in full Dolby Pro Logic II surround sound.

Dolby Headphone  
A brief introduction  
Dolby Digital and DTS provide discrete left and right surround channels,  
for more precise localization of sound and a more convincing, realistic  
ambience. Discrete means that each channel contains its own particular  
audio information and plays a unique role in creating a realistic surround  
sound experience.  
Up until now all this was reserved to speaker set-ups, but thanks to  
Dolby Headphone, the ultimate experience in home theatre surround with  
five (left, right, centre, rear-left and rear-right) discrete channels of digital  
sound quality is now also available to headphones.  
Dolby Headphone is a revolutionary signal processing system that works  
not only with multi channel audio but also with conventional stereo signals.  
In case of multi channel audio signals, Dolby Headphone technology will  
process these signals in such a way that you will experience the sound  
through your headphone as if it were coming from an actual five speaker  
home entertainment set-up. And even when listening to conventional stereo  
signals, Dolby Headphone will give you a much more natural and less  
fatiguing listening experience, equivalent to a good two-speaker playback  
system in a room with good acoustics.  
Dolby Headphone technology can model the sound of a playback system in  
up to three different listening environments, based on acoustic  
measurements of real rooms:  
DH1 is a small, well-damped room appropriate for both movies and  
music-only recordings.  
DH2 is a more acoustically live room particularly suited to music  
listening, but also great for movies.  
DH3 is a larger room, more like a concert hall or movie theatre.  
You can easily switch between these room modes and select whichever one  
suits the particular program material and your own preferences.

Advanced technologies used in HP 1500  
The HP1500 makes use of several advanced technologies.  
Principle of determining the direction of sound  
People can determine the localization of sounds through the perception of  
differences in intensity – so called Interaural Intensity Difference (IID) – and  
through time differences – so called Interaural Time Difference (ITD).  
IID is about the fact of sounds being louder as they are closer to the ear  
and being louder in case they have a non-obstructed path to the ear.  
ITD is about the fact that in most cases sounds will arrive earlier in time at  
one ear than at the other.  
In fact it is the environment itself that greatly impacts the sound before it  
reaches our ears. Reflections and absorption all will influence the sense of  
distance and direction we associate with a sound.  
Combining IID and ITD will allow the brain to determine the direction of  
sounds only in a rough way. It is in through the combination of IID and ITD  
and the way sounds are filtered because of the structure of the pinna  
– the outer ear – that allows to brain to accurately localise sounds.  
Depending on how a sound wave hits the pinna, it will be emphasized  
or suppressed.  
Depending on how a sound wave hits the pinna, reflections within the  
pinna are created, altering the phase relationship within the spectrum of  
the sound wave.  
And also: higher frequencies are more affected by the pinna than lower  
frequencies.That’s why our brain can easily locate higher frequencies,  
rather than lower frequencies.  
0912HP_EU 09-12-2003 12:12 Pagina 8

ENGLISH  
If we wish to reproduce all those effects through an audio system, than we  
need to take IID, ITD, pinna effects, room impulse response, etc. into  
account.That is where Head-RelatedTransfer Functions (HRTF) come into  
play.  
An HRTF is a mathematical equation that describes how a sound is effected  
when travelling from its source to our ears.  
There are several ways to synthesise an HRTF.The most common way to  
measure an HRTF makes use of placing tiny microphones in a listener’s ears.  
Every person has its unique HRTF. However, we can identify crucial parts in  
an HRTF that are responsible for localization of sound as if this sound  
would be radiated by a typical home cinema speaker set-up.  
When these parts are synthesized in an optimal way, a typical 5 speaker set-  
up listening experience is created.  
HRTFs are implemented in real-time Digital Signal Processors (DSP) and  
will then be applied to audio signals in order to reproduce "spatial" cues, i.e.  
create a sense of directionality.  
It is through these techniques that Philips is able to bring you a home  
cinema experience through a headphone that is as real as when you would  
be listening to an actual 5.1 speaker set-up.

Automatic Audio Signal Routing  
The Automatic Audio Signal Routing (AASR) feature of the HP 1500  
basestation allows for audio sources to be connected to its audio inputs and  
at the same time it can pass those same audio signals on to – for example –  
your Home Cinema receiver.This allows for permanent audio connections  
to be made without the need for swapping cables.Whether you want to  
listen to your headphone or your existing speaker set-up, it no longer  
involves tiresome swapping of cables: the choice is yours at the flick of a  
switch.  
Intelligent user interface  
After a digital analysis of the audio input signal the display will indicate which  
sound processing features can be activated. No more frustrating pressing of  
all buttons. Just read the display and select out of the active sound menus.  
Headphone construction  
The headphone’s semi-open construction will benefit the transparency of  
the sound.This will make you experience your favourite tracks under even  
more realistic conditions.  
Neodymium magnets  
Neodymium is the strongest magnet material available, which optimises the  
behaviour of the speaker coil for increased sound pressure levels and a  
more powerful bass response. All this at the lowest possible levels of  
distortion.

Night mode section  
a) button to activate Night mode  
– Night mode will reduce the dynamics of the audio signal.This will  
result in both the loudest and the most silent audio signals becoming  
clearly audible, even at lower volume levels.  
The audio signals on a DVD movie disc have large dynamics, i.e. the  
difference in loudness between the loudest and most silent signal can  
be very large. In order to hear both the loudest and most silent signal  
you normally would have to turn up to volume of the headphone.  
In case however you would prefer to listen at lower volume levels, it  
could result in the most silent signals becoming difficult to hear: by  
making use of the night mode this can be resolved.

When connecting your audio equipment in this way, you will be able to benefit  
from the Automatic Audio Signal Routing (AASR) feature.As long as the base  
station is powered – even in stand-by mode – the audio signal from the audio  
source will be made available not only to the digital base station but it will be  
routed through to the rest of your home entertainment set-up.Without the need  
for swapping cables you can decide whether you wish to enjoy the audio  
through your headphones or through for example the speakers of your home  
entertainment system.  
3 Check if the red RCA plug (right channel) is connected to the right  
channel (red) of the audio source.  
The white RCA plug (left channel) must be connected to the white

5 Output adjustment of your audio source: in case the line output of your  
audio source has an adjustable output level, adjust the line output level of  
the audio source to the highest acceptable undistorted level.  
Note: In case of certainTVs, the line output level can only be  
adjusted through theTV’s on screen menu.  
6 Power on the base station: switch on the digital base station.  
The power indication LED of the base station will change from red to  
green.  
7 Sensitivity switch: if your audio source’s output signal is relatively weak,  
the sensitivity switch at the back of the digital base station should be  
changed from 0dB to +6dB.This will provide the necessary additional  
amplification to the audio input signal prior to processing.  
If this results in a distorted signal, then set the switch back to 0dB.  
8 Source select: select the analogue input on the base station by pressing  
the ‘Source’ button.  
9 Input signal detection: once a stereo audio signal is detected the input  
signal indicator ’STEREO’ will be illuminated.
