4K HDMI Audio Extractor with Audio Amplifier, RS-232 and IP Control


4K HDMI audio extractor with EDID management

Built-in 50 watt audio amp for direct connection to 8 Ohm speakers

Separate analog audio input for connection of line-level mics or other audio inputs

Volume control via, front panel, RS-232, Digital Pot (rotary encoder), and IP

Volume, Audio Mix, and TV power control via built-in WebGUI or Telnet

2nd RS-232 port for controlling auxiliary devices


The EMX-I-AMP is a 4K HDMI Audio Extractor with built-in 50 watt audio amplifier for direct connection of 8 ohm speakers. The device also provides line-level stereo Aux audio input and allows audio mixing of  HDMI audio with the Aux input. Volume can be controlled from the front panel, RS-232, IP or external digital rotary pot (encoder) that can be mounted on a wall-plate.
The EMX-I-AMP also features a second independent RS-232 output port that can be used to control other devices such as a video projector. Using the primary RS-232 input, the user can send power on/off commands to the display through the secondary RS-232 port. Full EDID management is provided with the ability to learn, download, upload, emulate or pass-thru EDID. A USB port is featured on the front panel that can be used to configure EDID behavior, update firmware, and more.


The EMX-I-AMP can be used as a stand-alone control system since it has the ability to store power ON and OFF commands for connected displays. Users can recall those commands, or it can operate autonomously where upon detecting video, it outomatically sends an ON command and once there is no video, after a programmable delay it sends an OFF command to the connected display.


The EMX-I-AMP has the ability to control volume, Aux input mix, and control power of connected display. The EMX-I-AMP features built-in WebGUI that can be accessed from any PC or smartphone, and it also includes a full set of Telnet commands for advanced installations with 3rd party LAN-based control systems.
