Automatic Audio Signal Routing (AASR)
The Automatic Audio Signal Routing (AASR) feature of the HD1500U base
station 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 wireless 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. For graphical illustration of AASR, please refer to the
Quick Startup / Reference Guide.
Digital Wireless Transmission
Digital wireless transmission provides a wireless audio connection with
digital quality specification.The digital audio link has an improved robustness
compared to analog wireless systems. It will offer the highest possible level
of wireless audio quality.

frequency (UHF) as signal carrier, ensuring a very clear, sharp reception.
Even silent passages in classical music and plain silence in between two
music tracks are reproduced as pure silence. Never before has a wireless
headphone sounded so close to a corded headphone!
Double Phase Locked Loop (PLL) system
Not only the transmitter but also the digital wireless headphone is equipped
with a Phase Locked Loop (PLL) system providing the ultimate in
transmission and reception frequency stability.

Antenna diversity

The digital RF headphone is provided with a patent pending antenna
diversity system that can cope with changing receiving conditions when
walking around.This automatic system extends the operating range and
minimizes the dropouts experienced with analog wireless headphones.
