2.4GHz Radio Transmission
Transmission Area
Using radio waves to transmit signals, the effective transmission area is greatly
different to infra-red systems.
With infra-red, you have to stay within certain left-right and top-bottom angles
to the base station. The effective transmission area is a pie sector with the
base in the center.
But, with radio frequency, the effective transmission area is a circle.
Transmission range is 30m radius, compared to DIR2000C's 10m by infra-red.
Radio transmission can wrap around most obstacles, even doors and walls. But,
reinforced concrete walls, and metal doors can reduce signal strength.
3x3 Transmission System
A robust system to provide smooth data transmission.
To avoid and minimise interference with other radio networks in your home,
the base station constantly scans thru 3 channels for a clearer transmission
channel. It also sends data 3 times as backup to ensure none or miminal data
loss.

Dolby Headphones
With the Dolby Headphones chip, the realism of 5.1ch surround sound is produced
in a headphone.
With 3 Dolby modes, DH1, DH2, DH3, each giving an increasing sense of space
and reverberation.
- DH1 simulates a small room
- DH2, an average-size room
- DH3 re-creates the acoustics of a small movie theater

MPEG-2

The Headset
Improved Design
The DRS3000C system's headset, DHP3000 has many improvements over DHP2000 (headset
for older model DIR2000C).

control is on the right earcup.
It intelligently automatically powers off when placed lying down, ie. when
not in use. When you wear it, it automatically turns on.
Superb audio quality
The headset by itself, even without surround sound features, is a great headphone,
comfortable and stable to wear, and superb audio quality. Like most large diameter
headphones, the 50mm voice driver gives a superb sensory experience.
Charging
To charge, simply place the headset on the vertically standing base. Clever
convenient design, charges and holds your headphone. No need to fuss around
for an AC adapter, and no need to buy a headphone stand.
Charging contact points are on top of the headband. Placing it on the base
station is a breeze, the grooves
clicks in easily.
Charging time is 3 hours, giving 7 hours of usage.
Comfortable
to wear
Large 50mm earcups will effortlessly cover over your ear. Together with the
comfortable earpad, you can wear it for long periods without any strain.
Share the Joy
As with other Cordless Systems, you can buy additional headsets to tune in
to the same base.
48bit Digital Signal Processing DSP chip
The base station is equipped with a high end 48bit DSP circuit to produce clear
and high quality audio sound.
The Base Station
The
front panel's many indicators conveniently displays what input signals and output
channels.

There is no remote in this system. So, yes, you can only change the sound mode
at the base station :(
There is also no headphone port. Well, it is a cordless system! |
