FEATURES (Cont.)
nn
Quad-standard decoder– The System 4LQxi is com-
patible with all standard video formats including
NTSC 3.58, NTSC 4.43, PAL and SECAM.
nn
Built-in line quadrupler– The System 4LQxi includes
a built-in line (scan) quadrupler which eliminates scan
lines on video images by quadrupling the number of
lines displayed. The input video (15.7 kHz) is con-
verted to a 63 kHz RGB line quadrupled analog sig-
nal– especially useful for large screen displays.
nn
Three-line adaptive comb filter– A built-in three-line
adaptive comb filter helps provide crisp, stable output
from the System 4LQxi.
n Motion mode compensation– The System 4LQxi
line quadrupler has motion mode compensation to
eliminate the "jaggies” which are commonly associated
with enhanced video such as and line quadrupling.
n Universal inputs– The System 4LQxi has four uni-
versal inputs capable of accepting all computer RGB
signals, composite video and S-Video standard signals
(NTSC, PAL and SECAM). No optional modules are
needed for each input signal type. Looping capabilities
allow for up to 22 inputs.
nn
Balanced/unbalanced stereo audio inputs– Every
System 4LQxi is capable of switching up to four bal-
anced or unbalanced stereo audio signals. Input
through professional captive screw terminals, audio
can be switched to follow any video or RGB input sig-
nal or “broken away” for maximum flexibility.
n Triple Action Switching™ (RGB delay switching)–
Exclusive to Extron, this unique delay switching fea-
ture in the System 4LQxi makes it possible to have
“seamless” switching for all projector models. This is
done by a triple-action switch. When an input is
selected (either by front panel or RS-232), the RGB
video is turned “off” and sync is left on, then sync is
switched to the new source and finally, RGB video is
turned back “on.” This makes “glitch free” switching
possible with every projector on the market.
n LCD menu-driven picture and programming con-
trols– The System 4LQxi has an LCD menu that
makes set-up and programming of its many features
or functions simple. An alpha-numeric display allows
for any of the line quadrupler controls such as color,
hue, contrast and detail to be adjusted and stored in
memory for each input.
nn
Picture control memory– Each input has a separate
memory block for all picture controls of video or
RGB signals (including audio switching). These may
be set and stored by the System 4LQxi.
n Sync polarity programming– The output sync polarity of
the System 4LQxi may be programmed to be either posi-
tive or negative going for both horizontal and vertical
sync signals, ensuring that any projector will differentiate
the line quadrupler’s output from that of a 1280 x 1024
SUN or SGI work station.
nn
Universal projector control– Extron’s System 4LQxi is
fully compatible with all digitally controlled projectors.
Using the projector-brand remote control, the System
4LQxi can be made to switch inputs, power “on” or “off”
the projector, mute the audio or video signals and switch
the four inputs. This may also be accomplished by using
the System 4LQxi front panel controls or through a third
party control system via RS-232, in order that the switch-
er is able to “talk” to the projector.
nn
Universal compatibility– The System 4LQxi communi-
cates using the projector manufacturer's remote control
with all digitally controlled projectors on the market
today such as Ampro, Barco, Electrohome, Hughes/JVC,
Mitsubishi, NEC, Panasonic, Runco, SELECO, Sony
and Toshiba as well as the Mitsubishi XC Series monitors.
n RS-232 control– The System 4LQxi has built-in RS-232
control for third party control of any of its features or
functions. Extron has also developed a free Windows
®
based control program which allows the 4LQxi to be con-
trolled by a remote PC.
n 300 MHz RGB video bandwidth– The 300 MHz
(-3 dB) bandwidth of the System 4LQxi allows for the
connection of video signals and super high resolution
computers such as SUN, Silicon Graphics, VESA,
M
AC/Quadra, SuperVGA, PowerMAC, Power PC, HP,
NCD, Chromatics and DEC workstations. This ensures
the highest resolution possible for any application.
n RGBS or RGBHV output– The System 4LQxi converts
all video inputs to an RGB output. This one output
(RGBS or RGBHV) makes the System 4LQxi easy to
connect all video signals to any projector brand through
one cable.
n 1U rack-mountable enclosure– The System 4LQxi is
housed in a metal 1U high, rack-mountable enclosure,
with an internal auto-switchable 100-240 volt auto-
switchable power supply. Enclosure includes rack “ears”
and hardware.
n Triple-split screen mode– Extron’s System 4LQxi has a
triple-split screen mode that displays TSC/PAL/SECAM,
line doubled video and line quadrupled video simultane-
ously on the same display. This provides the opportunity
of showing the advantages of image purity and brightness
when using a line quadrupler.
