Marantz Cinema 70s: adjust audio that arrives before the picture
Marantz Cinema 70s: adjust audio that arrives before the picture. Check prerequisites and the actual response before reporting an outcome.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Known HDMI route with audio early; this delay cannot advance already-late audio.
Connection scope: HDMI / ARC / eARC audio. Symptom: Sound and picture are out of sync.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Does audio arrive before the matching lip movement?
If audio is already late, adding audio delay can worsen it; stop rather than apply this procedure.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → May this input timing setting be changed temporarily?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-1
May this input timing setting be changed temporarily?
It is saved separately for each source. Note the existing value so it can be restored.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Open OPTION > Audio Delay
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-2
Open OPTION > Audio Delay
Select Audio Delay and ENTER on the current input; do not guess whether the TV supports Auto Lip Sync.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Select Adjust and add only a small delay
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Select Adjust and add only a small delay
Use left/right within0–500ms while comparing the same scene. Keep the original value and revert if worse.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Is timing closer on that same source and scene?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-4
Is timing closer on that same source and scene?
A setting change alone is not proof of an improvement. Stop if the required correction would need negative audio delay.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.

Possible result
Checks completed — report what happened
Completion is not an automatic solved result. Report solved, partly helped, did not help or could not follow based on your actual observation. No Audio Review physical test is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Keep these observations for official support
A required prerequisite or response was not confirmed. Stop this sequence and use the exact model and partner documentation. Do not escalate to a factory reset, firmware installation, internal repair or unsafe wiring change.
next support
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
A required fact is unknown
Confirm the exact model, connection, partner capability and current control state before continuing. Do not guess settings or operate an updating product.
