2:1 HDMI+VGA 4K Scaling Switcher


The Absolute Acoustics® NDS-SS21 is a multi-format switcher designed to manage signals in corporate meeting rooms. Its architecture combines HDMI, VGA and audio connections providing native support for devices with different capabilities. Its 2 inputs — 1 HDMI and 1 VGA + analogue audio — are routed to 1 HDMI and 1 3.5mm analogue audio outputs.

In addition to the analogue-digital conversion to HDMI (including audio embedding), SS21 VGA input is processed by a high-quality video scaler, sending video in the ideal resolution to the system display. For HDMI inputs, a set of EDID modes is available for configuration, adapting the device for different kinds of applications.

SS21 can be controlled manually via buttons on its front panel, by sending RS232 codes or automatically, through the SmartSwith™ algorithm, that selects the last connected source to display. SS21 also features our CEC Bridge™ technology, which enables sending CEC commands for display control, avoiding the use of external control devices.
