The AC-MX-42 is a 4×2 HDMI matrix switch. This switch allows any source (Blu-ray, satellite receiver, game consoles, PCs, etc. ) to show on connected displays. In addition, this matrix equalizes and amplifies the output to ensure the HDMI signal will transmit through long HDMI cables without losing quality. The AC-MX-42 is ideal for bypassing legacy AVRs that do not support full 18Gbps. Instead of bottlenecking video quality through a legacy audio device that can’t handle 18Gbps, integrators can run down-scaled video to a legacy audio device and send uncompressed HDMI to the display. Audio remains untouched on a down-scaled output, making it an ideal component for systems where high bitrate audio is critical.
NOTE TO DESIGNERS, INSTALLERS, AND TECHNICIANS
When used with an AVR or a Pre-processor as an HDMI video bypass around outdated onboard AVR or Pre-processor HDMI video signal technology, especially when introducing a Next-Gen video display into a system while retaining an existing AVR or Pre-processor that remains compatible with current immersive audio codec reproduction, the following must be noted: When the main HDMI video display output of the bypassed AVR or Pre-processor is left untethered to an EDID-producing device, the AVR or Pre-processor has no means for EDID negotiation or authentication. As a result, source devices fail to detect an active EDID-managed HDMI path. An AVR or Pre-processor may not fully activate or switch to the desired input for audio capture if no active output is detected or fails to enable proper input signal processing.
BEST PRACTICE is for the AVR or Pre-processor to terminate into a device that produces an active EDID, which serves to “trick” the AVR or Pre-processor into continuing to function as designed (with a video signal and multi-channel audio selected at one of its inputs, expected to transfer the video signal to a display device with EDID authentication). An AVPro Edge AC-SC-1X or AC-DA12-AUHD-GEN2 with EDID management is ideal for overcoming this anomaly as both have EDID management capabilities; however, any device capable of producing an EDID compatible with maintaining the AVR’s or Pre-processor’s stability may be utilized.
