Denon and Marantz will soon be delivering the SPK618 HDMI adapter, designed to address 4K/120 Hz and 8K compatibility issues. Affected customers will receive the device free of charge.
Denon and Marantz will soon be providing the SPK618 HDMI adapter, designed to address compatibility issues between Denon and Marantz A/V receivers that support 4K/120 and 8K video resolutions and game consoles that support 4K/120Hz and 8K video resolution output.
The adapter will be provided free of charge to customers with the AVR models listed below during the warranty period.
The trigger
Some new 8K source devices that support output in 4K/120Hz and 8K video resolution did not work fully with Denon and Marantz 8K AVRs. When users tried to output 4K/120 or 8K from these specific 8K sources, the 4K/120 or 8K video could not be sent through the AVR. This problem occurred even when the AVR’s “8K Enhanced” menu/GUI option was enabled.
To mitigate the problem, Denon and Marantz advised users to connect the game console directly to the display and then send the audio back to the AVR via ARC or eARC. Another workaround was to output the 8K source in 4K/60 resolution. At that video resolution, the AVR was able to pass the picture on without any problems.
With the new SPK618 HDMI adapter, these workarounds are no longer necessary and the problem is a thing of the past.
The SPK618 adapter
The SPK618 adapter corrects the HDMI input signal from the console/source and delivers the corrected HDMI data to the AVR, ensuring compatibility. The SPK618 adapter is available to customers who own one of the AVRs listed below and are experiencing the throughput issue.
Users are advised to update the firmware of their AVR. This will ensure adapter compatibility even if their products are not set to Auto Update.
