The Gefen Audio/Video Scaler Pro with Amplifi er
The Gefen Audio/Video Scaler Pro is an all-in-one, commercial-grade, rack-
mountable A/V switcher and scaler for a myriad of A/V source types. Amplifi ed
20W audio outputs for external speakers save further space by removing the
need for a separate amplifi er. The Gefen Audio/Video Scaler Pro allows you to
scale video and digitally enhance key aspects such as color, aspect ratio, and
A/V noise. External audio and video are digitized and combined into an HDMI
output signal along with external digital audio (S/PDIF and TOSLINK).
Video inputs can be standard defi nition or high defi nition television, computer
or High-Defi nition DVI-I (DVI-A or DVI-D), Component, Composite, S-Video,
and HDMI resolutions of up to 1080p. Outputs consist of two HDMI digital video
outputs, two digital audio outputs (S/PDIF, TOSLINK), and two 20W speaker
terminal outputs.
Anything from set-top boxes and DVD players to the next generation of gaming
consoles including the Xbox 360 and PS3 can be plugged into the Audio/Video
Scaler Pro.
Computer users will especially benefi t with the scaling of VGA and DVI video to
make better use of their viewing areas on wide screen monitors or televisions.
How It Works
Audio/Video sources are connected to free ports on the scaler (see the next
paragraph for further details). Output devices such as HD displays connect to
one of the HDMI outputs. Easy to use on-screen menus accessible through
the IR remote control allow for effortless setup and image adjustment to
accommodate different viewing modes and screen sizes.
In order for HDMI output to contain digital audio, each video input source must be
paired with a like type of analog or digital audio in order for the scaler to output
HDMI with digital audio. For example, analog video sources VGA, Component
and Composite/S-Video are input along with analog 2-channel L/R audio. For
multichannel digital results, two HDMI or DVI-D sources could be input with
external digital audio (S/PDIF or TOSLINK). The result in both cases is a single
HDMI signal emerging from the two HDMI output jacks, with both embedded and
external digital audio available on the coaxial and optical outputs.
