Convert PC audio/video to full-screen HDMI with simultaneous analog & digital audio output

Upscale an analog video signal from a computer or VGA source to a high quality digital HD display. The Gefen VGA Audio to HDMI Scaler supports a range of video resolutions up to 1080p. Also, it will take digital TOSLINK or analog 3.5mm mini-Stereo audio as input, and simultaneously output the audio signal in the same format. A comprehensive on-screen display (OSD) menu allows intuitive control over a range of A/V operations.

How It Works

Connect a VGA source to the Scaler input with a VGA cable. Next, connect the analog or digital audio input/output ports using 3.5mm mini-Stereo cable. Connect TOSLINK output from a digital audio source to TOSLINK input on the Scaler using TOSLINK cable. Finally, connect an HDMI-compliant display to the the HDMI output port. Audio signals pass to the amplifier from the Scaler through the audio cables, taking either analog or digital audio and embedding it into the HDMI output.

Power up the Scaler by plugging in the 5VDC line from the power supply. A clear picture will be displayed on the display.

Note:  The number of audio channels that are output by the VGA Audio to HDMI with Scaler depends on the audio that is input. In the case of an analog signal, stereo input passes through unmodified to the 3.5mm mini-stereo output, converted to 2-channel LPCM digital audio on the HDMI and TOSLINK output connectors. In the case of digital Multi-channel audio input formats, such as Dolby Digital 5.1/AC3 and Bitstream Audio these are passed unmodified to the TOSLINK and HDMI outputs, and not to the 3.5 analog outputs.
