The Oklahoma Bar Association recently upgraded its Emerson Hall meeting center with new projectors, LCD TVs, motorized projection screens, a digitally processed sound system and a Creator control system.

The control system includes the DTX-8400C wireless two-way touch panel located at the front of the house and the wall mount LT-7000C touch panel located at the back. The PGM-II central controller is installed in the equipment rack along with two CR-VOL volume controllers, a MAX-1301 multiple input video scaler and a VGA-0404A matrix switcher.

The IT staff at Oklahoma Bar was particularly impressed with the speed of the DTX-8400C wireless touch panel and its simplicity of operation. This last point was extremely important since most users are non technical.

The interface home page was designed to be self explanatory. It's neatly laid out with left and right columns containing selection buttons. When these buttons are pressed the corresponding page flip appears in the middle. Pressing the audio button, for example, flips to the Audio page where the user can ramp volume up or down. The volume level is displayed by a horizontal bar graph called a compression gauge that follows the volume in real time.

The RF receiver for the wireless touch panel is mounted in the ceiling and covers the enormous sized room without dead spots and because Creator operates on a dedicated RF frequency of 433 MHz, there aren’t the issues of signal dropout and latency associated with wireless panels using Wi-Fi technology.
