The HD-SC-500 can serve as the central component of a compact, automated AV system with the convenience of automatic input selection and display control.

Proposition 65 Warning for California Residents

The Atlona AT-HD-SC-500 is a 3×1 switcher and HD scaler with two HDMI inputs and a VGA input with audio. It is designed to take video signals from switchers, PCs, or laptops, and scale them to an HDMI output at a wide range of resolutions and rates, up to 1080p @ 60 Hz and 1920×1200. The HD-SC-500 can serve as the central component of a compact, automated AV system with the convenience of automatic input selection and display control. It enables input selection, volume, and display on/off control from the front panel or external RS-232 or TCP/IP commands. The HD-SC-500 incorporates many popular integration convenience features while delivering excellent value for classrooms, huddle rooms, and meeting spaces.

The HD-SC-500 offers advanced scaling capabilities including image adjustment capability, and an auto-set feature for matching incoming signals to the display’s native resolution. Integrated scaling helps optimize image quality and switching performance. This switcher and scaler also features audio de-embedding, and third-party TCP/IP and RS-232 control of the scaler and display. Surface mounting brackets are provided with the HD-SC-500 for easy under-table, furniture, or on-wall installation.

Automatic Display Control

The HD-SC-500 provides control to a display through TCP/IP, RS-232, or CEC*, without the need for a separate control system. This simplifies system design and integration while reducing costs. With automatic display control, the HD-SC-500 can trigger a display to power on automatically whenever a laptop or other device is connected. At the end of the presentation, when the presenter disconnects the laptop, the HD-SC-500 forces the display to power off. Ease of presenter interaction with the system, and the savings incurred by automatic display shutdown provide a significant return on investment. The HD-SC-500 display control capability can also be triggered by an external control system.

A power button on the front panel can be used for manual on/off control of either the HD-SC-500 or the display. Front panel volume controls are also available to control the display’s internal audio, or another device with volume control, such as a DSP or another switcher.

* Consumer Electronics Control (CEC): Atlona does not guarantee the function of CEC with all televisions. We can confirm proper operation with many current Samsung, Panasonic, and Sony TVs. Many manufacturers do not support the CEC “off” command when sent from a source and older TVs use proprietary commands. Atlona only supports those TVs that follow CEC command structure from HDMI 1.2a and support the “off” command when issued by a source. We encourage any dealer to get evaluation product from Atlona prior to designing a system around this control technology or be prepared to use other methods to control their displays if Atlona CEC is not compatible with the installed displays.

Reliable Auto-Switching

The HD-SC-500 automatically selects an input source based on detection of the 5 volt hot plug detect (HPD) signal, as well as active video. This ensures reliable auto-switching operation for all video sources, including DVRs, DisplayPort / Mini DisplayPort adapters, and other devices that always maintain the HPD line at the 5 volt “high” state but may not be delivering active video.

Applications

Complete system applications – The HD-SC-500 provides a compact, yet comprehensive and cost-effective system integration solution with automatic input selection, display control capabilities, and essential audio processing.

Expanding system capabilities – The HD-SC-500 can also be used as an input device on a switcher, matrix switcher, or distribution amplifier that doesn’t have a VGA input, and as a dedicated scaler for any device with an HDMI output.

Configured and Managed by AMS

The Atlona Management System (AMS) is a powerful network software platform ideal for configuring, managing, and monitoring the HD-SC-500 and other Atlona IP-controllable devices over a LAN, WAN, or VPN. AMS is available free from Atlona, and greatly streamlines installation and maintenance of several Atlona products throughout a facility or enterprise, from a standard web browser.

AT-OME-SW32

Also available from Atlona is the AT-OME-SW32, for applications requiring 4K/UHD compatibility. The OME-SW32 offers three-input switching for HDMI and USB-C sources, a matrix switcher for driving two displays, and selectable 4K downscaling to 1080p.
