Liviau R is a single-unit solution for control
of AV presentations in meeting rooms,
boardrooms, lecture theatres – or indeed any
location where there is a need for a simple and
elegant solution to fully control lighting, video
and audio sources.
Liviau R combines the functions of an
audio/video switcher, a file server, an internet
browser, a lighting controller, a stereo power
amplifier and an audio recorder in a single,
compact and elegant unit. The user interface
is a 10.1” multi-touch screen, which displays
a series of simple, icon-based pages. Each of
these is deliberately designed to offer only the
options required at any one time.
The touchscreen display may be mirrored
to other portable devices using the build in
Teamviewer® application, allowing the system
58.3 mm [2.3 in]
59.8 mm [2.35 in]
93.5 mm [3.68 in]
to be controlled from elsewhere in the room.
Liviau R connects to a projector or flatscreen
display using HDMI, with control of the display
device being via either RS-232 or infra-red.
If the presentation program is a computer file,
it may be sourced from a file stored in Liviau
itself or from a USB memory device or even
wirelessly from another device (e.g., a laptop,
tablet, or smartphone) using the integrated
screen casting application MirrorOp®. An
external source of HDMI video (and audio)
such as a DVD/DVR player or PC may
alternatively be selected. Providing the network
connection is Internet enabled, web pages
may also be accessed and displayed, using
Liviau R’s internal web browser.
Liviau R’s audio performance is exemplary:
the unit provides six balanced analogue inputs
(two mic, four line), six balanced analogue
audio outputs, a fully assignable audio mixing
matrix and a high quality
50W/channel stereo power amplifier. A 4-band
parametric equaliser is included on every input
and output, and additionally, each output has
a limiter and crossover facility, thus permitting
the use of high quality bi-amped loudspeakers.
Master control of volume is always available
with a virtual fader on all screen pages.
Liviau R also has an integral 48 kHz/24-bit
digital audio recorder, which can be used to
record the proceedings of meetings (approx.
500 hours capacity) or other programme
material, either internally or on a USB memory
device.
In addition to the RS-232 and infra-red outputs,
an industry-standard DMX512 port is fitted,
permitting the unit to interface directly to
many common lighting control systems. A
dedicated page is included on the touchscreen
which allows control of individual lighting
groups, colour definition and recall of preset
lighting scenes. Master control of lighting level
is always available with a virtual fader on all
screen pages.
There are also four GPOs, two GPIs and two
GP ports that may be defined at installation as
either inputs or outputs. These may be used to
control other room functions, such as blinds,
projector lift, projection screen, etc.
Liviau R can be installed as a free-standing
unit, integrated into furniture or wall-mounted.
It is built in a very stylish, custom aluminium
enclosure, and includes an ambient light sensor
to adjust screen brightness and a proximity
sensor to wake the system. Liviau R is silent
in operation (no fans) and is powered by a
separate external 24 V PSU (supplied).
