The Atlona AT-DRC444 is a Multi-Input Presentation Switcher designed with 3 x Audio and Video Switcher platforms built into one product.

The Atlona Multi-Input Presentation switch includes 4 inputs, one output Composite Video Switch; 4 inputs, one output VGA switch; and 2 input DVI and 2 input HDMI to one DVI Output Switch. Each video input is accompanied with its own audio input. Furthermore, the switcher is featured with microphone input and allows user to mix the microphone signal with the main audio in "talk-over" mode. The Atlona DRC444 is designed to be controlled via RS232, RS485 or IR.

FEATURES

- Offers 3 separate switching platforms which includes 4 inputs, one output Composite Video Switch; 4 inputs, one output VGA switch; and 2 input DVI and 2 input HDMI to one DVI Output Switch.

- Either platform (Composite, VGA or DVI/HDMI) could be switched simultaneously, as all 3 Video Platforms are completely separated from each other.

• Each video input is accompanied with its own audio input (total 12 audio inputs)

- Microphone input, allows user to mix the microphone signal with the main audio in "talk-over" mode.

- Video:

a) The DVI/HDMI inputs can support extremely high resolutions up to 1920x1200 and fully EDID and HDCP compliant. DVI/HDMI platforms will pass up to 10.2Gbps

b) The VGA inputs can support extremely high bandwidth of 750MHz and therefore up to 3200x2400 in resolutions. The VGA platform fully supports DDC.

c) The Composite video inputs are compatible with NTSC 3.58, NTSC 4.42, PAL, and SECAM formats.

- Audio:

a) Twelve inputs include four stereo balanced/unbalanced on capture screw connectors on Composite Video Platform, for 3.5mm (1/8-inch) audio inputs on VGA platform and four stereo balanced/unbalanced on capture screw connectors on DVI/HDMI platform.

b) Each one of the Audio inputs supports separate Audio adjustments and presets.

• Auto-control and Learning function:

a) The AT-DRC444 can learn and automatically transmit the RS232/RS485 commands to the Display which allows switching the display on/off or changing inputs.

- Control :

a) RS-232 input, allows user to control the DRC444 with a 3rd party control system.

b) RS-232/RS-485 output, programmable output, allows users to send commands to Display's.

c) IR remote control.

- Rack-mountable. 1U height.

- Internal power supply (100Volt\~240Volt AC, 50/60Hz)

TROUBLESHOOTING

1. Image Ghosting is usually related to the low quality cables or extremely long length. Please try replacing cables with extenders or better quality cables.
2. If user is not able to connect to the DCR444 via RS232, this may be related to either incorrect COM port being used or incorrect wiring on the serial cable. Please use the supplied RS232.
3. Interference on the output signal is usually caused by long cables or if switcher is not grounded. Please rack-mount the switcher and make sure that the rack is grounded properly.
