Features
Inputs —
Video inputs — The switcher switches among:
•
Two fully-configurable RGB video inputs on 15-pin HD connectors
•
One HDTV component video, interlaced component video, or progressive scan video
on three BNC connectors
•
Two S-video inputs on 4-pin mini-DIN connectors
•
Two composite video inputs on single BNC connectors.
•
One single link of DVI-D on a DVI connector with EDID emulation
Audio inputs — The switcher switches among eight unbalanced stereo audio inputs,
five inputs on left and right RCA connectors and three inputs on 3.5 mm mini stereo
jacks. Inputs can come from sources such as a VCR, DVD player, computer audio card, or
other audio device that outputs a stereo line-level signal.
Outputs —
Video outputs — The IN1508 outputs scaled video signals as progressive RGBHV,
RGBS, RGsB, or component video, from 640 x 480 (VGA) up to 1600 x 1200 (UXGA), to
match the optimum or native resolution of virtually any display device, on a 15-pin HD
connector.
The output refresh rate is selectable as desired through the on-screen display menu.
When used with LCD or DLA displays, Extron recommends the 60 Hz setting. Higher
output refresh rates can be used with CRT displays to reduce flicker.
Audio outputs — The switcher provides an unbalanced line level signal that is identical
to the input signal. This output can drive any line level compatible audio unit, or a local
device such as powered speakers.
Video output resolutions — The IN1508 outputs an image scaled up to a wide variety of
output resolutions and rates (see
for a detailed list).
Seamless Switching — The IN1508 provides a seamless transition between scaled low
resolution video inputs (inputs 1 through 4 [or inputs 1 through 5 if input 5 is configured
as interlaced component video]) and the high resolution inputs (inputs 6 and 7 [or inputs 5
through 7 if input 5 is configured as progressive component video or HDTV]).
Picture-in-picture — Two inputs can be displayed on the IN1508 output simultaneously
by using the picture-in-picture (PIP) feature. The two images displayed must come from
different input groups (one high resolution and one low resolution). The primary and
secondary PIP inputs can be instantly swapped at the touch of a button.
Inverse 3:2 pulldown detection for NTSC video sources and 2:2 film detection
for PAL video sources — This advanced film mode processing feature helps maximize
image detail and sharpness for video sources that originated from film. When film is
converted to NTSC video, the film frame rate has to be matched to the video frame rate in
a process called 3:2 pulldown. Jaggies and other image artifacts can result if conventional
deinterlacing techniques are used on film-source video. The advanced film mode of the
IN1508 processing recognizes signals that originated from film. The switcher then applies
video processing algorithms that optimize the conversion of video that was made with the
3:2 pulldown process. This results in richly detailed images with sharply defined lines.
A similar process is used for PAL film-source video.
