What is included with the OHM633
1.INTRODUCTION
The Clarion OHM633 is a high-performance video monitor
designed specifically for the mobile environment. It is
intended for use with other Clarion multimedia products, and
can also be integrated with many other products as part of a
complete mobile video solution. With two video inputs, the
OHM633 can support simultaneous connection to both
dedicated video source units and optional audio/video
components such as camcorders or videogames. The
infrared remote control receiver output allows integration with
select Clarion DVD and VHS source units.
The OHM633 automatically switches to operate with either
NTSC or PAL video signals (NTSC is the standard North
American video format).
The 16:9 aspect ratio screen allows DVD films to be viewed
in their original aspect ratio for the best cinematic experience.
Note:
The OHM633 is designed to be a component in a full audio/video
system. If you have any questions about compatible components,
such as system controllers, source units, FM modulators, or
other audio/video products, please contact your authorized
Clarion dealer.
