Atlona announces presentation switcher15 March 2011
Atlona Technologies has introduced its AT-DRC444 multi-input presentation switcher. Featuring three separate audio and video switching platforms in one product, it combines a microphone input, RS232 input for control via third-party control systems, and RS232/RS485 outputs for full control over projectors or displays.
The AT-DRC444 includes four inputs with one output composite video switch; four inputs with one output VGA switch; and two DVI and two HDMI inputs with one DVI output switch. Each video input is accompanied by its own audio input, for a total of 12 audio inputs. All three video platforms are completely separate, allowing them to all be switched simultaneously.
The switcher features a microphone input and allows users to mix the microphone signal with the main audio in "talk-over" mode. For example, if a DVD is playing, the microphone can be used over the DVD player’s audio channel. The AT-DRC444 is designed to be controlled via RS232, RS485, or IR. In addition, the unit is equipped with RS232/RS485 programmable output, allowing users to send commands to projectors and displays.
“We are excited to introduce the new AT-DRC444, which is the ultimate switching solution for classrooms, conference and boardrooms, and many other presentation environments,” said Ilya Khayn, president of Atlona Technologies. “By combining three switching platforms into one unit, the AT-DRC444 offers a cost-effective solution for any A/V system, while providing the control options needed for a simple user experience.”
The AT-DRC444’s DVI/HDMI inputs support resolutions up to 1,920 x 1,200 and are fully EDID and HDCP compliant. The VGA inputs support high bandwidth to 750 MHz for resolutions up to 3,200 x 2,400, while the VGA platform fully supports DDC. Composite video inputs are compatible with NTSC 3.58, NTSC 4.42, PAL and SECAM formats.
The unit’s 12 audio inputs include four stereo balanced/unbalanced on capture screw connectors for the composite video and DVI/HDMI platforms, and 3.5-mm (1/8-inch) audio inputs for the VGA platform. Each audio input supports separate audio adjustments and presets.
