Ethereal by Metra Home Theater Group (MHTG) is introducing its next generation of the HDMI All-in-One Correction Tool, the HDM-AIO2, at the 2019 CEDIA Expo. According to MHTG, this product fixes most of the common HDMI problems that installers experience in today’s home theater systems, and now has a smaller footprint, lower price tag, and a redesigned circuit board to increase efficiency and provide faster input switching. The HDM-AIO2 will be shipping soon and on display at the 2019 CEDIA Expo booth #1338.
When an HDMI signal is initiated there is a 5V trigger sent from the source to the display to wake the display up, the display responds with the Hot Plug Return Trigger to let the source know that it is there and ready to negotiate. However, this process can get sidetracked quite easily by a number of factors, including:
- Voltage and or current that is too low on either the 5V/Hot Plug return.
- Hot Plug is not interrupted between source selections (this is necessary for the EDID reset).
- Insufficient voltage and current being returned down the TMDS channels.
- EDID (DDC) Rise Time is too high due to capacitive loading on the low speed data bus.
The HDM-AIO2 provides a hot plug interrupt, fixes EDID start up issues, supplements voltage/current in the TMDS feed, 5V feed, and hot plug feed, plus provides voltage matching for both input and output of the device. This ensures that the common rail voltage is consistent from source to sink. Its EDID capacitive stripping corrects the most common EDID problems, including audio dropouts, “Mode Not Supported,” and “Frequency Out of Range” error messages. Once it is correctly installed and connected to a controlled relay, the HDM-AIO2 will usually resolve all of the problems listed above.
The HDM-AIO2 supports up to 24 Gbps bandwidth and all versions of HDCP formats. It includes impulse synchronization. No other product on the market has all of these features in one device, designed to reduce the time and stress of troubleshooting for hours at the end of a project.
Metra Home Theater Group will also be hosting a workshop at the CEDIA Expo featuring Jeff Boccaccio, president of DPL Labs, one of the industry’s leading experts on digital signaling solutions and HDMI, along with Brent McCall from MHTG’s technical support and product development team. This one-hour long workshop session is hosted at MHTG’s booth, #1338, on Thursday 9/12 and Friday 9/13 at 1:00 PM. Both days will have the same session topic and attendees will be entered in a drawing for a chance to win new products.
