The DA-H4A-DS is an HDMI 2.0 compatible 1x4 auto scaling HDMI distribution amplifier. It supports automatic down scaling so a 4K video input can be down scaled to an 1080p output when connecting a display that only supports resolutions up to 1080p for maximum compatibility in installations with mixed resolution displays.The DA-H4A-DS supports 4K signals up to 4K@60Hz 4:4:4 and features an easy EDID management option using dip switches on the front panel of the unit. The Distribution Amplifier can de-embed digital stereo audio to one balanced analog audio output and one optical Toslink audio output to provide audio sources for existing audio systems. The Distribution Amplifier supports 4K to1080p down-scaling up to 4 outputs. Moreover, the Distribution Amplifier provides a Micro-USB port for convenient firmware upgrade.
Features
- Splits a single HDMI input to four HDMI outputs.
- Supports HDMI 2.0, 4K@60Hz 4:4:4, Dolby Vision.
- 18Gbps high bandwidth.

- Supports video resolution down-scaling, the 4K input can be automatically degraded to 1080p output for compatibility with 1080p display.
- Built-in signal equalizer provides capability to use longer range HDMI cable.
- Up to 6 types of built-in EDIDs can be selected by DIP Switch.
- Balanced analog and Toslink optical audio outputs for de-embedded audio.
- Up to 6 units can be cascaded to distribute video signal to multiple video displays.
- CEC pass-through.
- Micro-USB port for convenient firmware upgrade.
