System configuration

The HD 1500 system consists of a digital base station and a digital wireless
RF headphone.The base station contains a digital signal processor and a
digital FM transmitter 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 data streams that can be handled by the digital headphone
whilst still maintaining the directional information in the audio 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.
The digital wireless RF headphone that comes with the HD1500 system will
provide you with pure digital audio quality. Due to the RF wireless
technology you are not restricted to remain within the line-of-sight of the
base station, as would be the case with conventional IR cordless systems.
