instructions for experienced installers on how to install, configure, and operate the

DVS 304 Series Description
The DVS 304 Series of digital video scalers is comprised of DVS 304 and DVS 304 DVI
models
• DVS 304, DVS 304 D, DVS 304 A, and DVS 304 AD
• DVS 304 DVI, DVS 304 DVI D, DVS 304 DVI A, and DVS 304 DVI AD
They are available as half rack, non-audio models or full rack size models with balanced/
unbalanced audio.
• Half rack: DVS 304, DVS 304 D, DVS 304 DVI, DVS 304 DVI D
• Full rack: DVS 304 A, DVS 304 AD, DVS 304 DVI A, and DVS 304 AD:
All models are 4-input, 1-output, high performance RGB and video scalers, providing
scaling solutions for boardrooms, conference rooms, and home theaters, as well as
rental and staging applications. The DVS 304 series scales from composite video, S-video,
component (Y, R-Y, B-Y) video, and RGB video to computer-video (RGBHV/RGBS/RGsB) or
HD component.
The four inputs of all DVS models accommodate composite video, S-video, component
video, and RGB. The fourth input is fully congurable to accept any available analog video
format from composite video to RGBHV. Additionally, with the exclusive Auto Input Format
Detection mode, the DVS 304 devices automatically detect and then process the incoming
signal format to this input.
The DVS 304 Series audio models offer four input audio switching for stereo unbalanced
or balanced sources, with gain and attenuation controls available for each input. All audio
connections are on captive screw connectors for ease of integration, and output volume
control eliminates the need for a separate audio preamplier in many A/V systems.
DVS 304 Models
On these models, two identical, scaled outputs are available on 15-pin HD and BNC
connectors. A total of 69 output scan rates are available from VGA (640x480) to UXGA
(1600x1200) resolution, as well as HDTV at 720p, 1080i, and 1080p/60 Hz.
NOTE: See the Resolution and Refresh Rate table in the Operation section, page 15,
for a comprehensive list.
