INTERFACE MODULES AND CABLES
QM-TX QuickMedia™ Transmitter
The QM-TX provides a low-cost multimedia interface
solution for QuickMedia-based Touchpanels and
MediaManager systems. Portable or rack-mounted,
the QM-TX can be used to send audio, video, and
computer signals to any QM-equipped touchpanel via
Crestron's exclusive single-wire QuickMedia transport.
Five BNC’s are provided on the QM-TX to accept
composite, S-Video, component, HDTV, or RGB
signals (up to 1600 x 1200 at 60 Hz). Balanced stereo
line-level audio signals are transmitted simultaneously
with 24-bit digital resolution. Video formats can be
switched dynamically and automatically under system
control. The QM-TX is 1/2-space rack-mountable
using the optional ST-RMK kit.
