Onkyo TX-RZ50 / TX-NR6100. Room-related coloration with an already valid AccuEQ calibration, unchanged room/speakers and current AccuEQ Off; not electrical crackling or clipping.
Connection scope: Device controls / power only. Symptom: Playback sounds distorted.
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
Is the concern room-related tonal coloration rather than crackling, damage, overheating or protection?
A possible electrical or speaker fault stops before a listening comparison.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Was a valid AccuEQ calibration already completed for the unchanged current room and speaker arrangement?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Was a valid AccuEQ calibration already completed for the unchanged current room and speaker arrangement?
Unknown, obsolete or absent calibration is not created by switching a preference.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is AccuEQ currently Off and available outside Pure Audio/Direct, with no Dirac Live filter active?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Is AccuEQ currently Off and available outside Pure Audio/Direct, with no Dirac Live filter active?
TX-RZ50 Dirac Live excludes AccuEQ; do not bypass an unavailable control or change listening mode to force it.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May the stored all-channel correction be compared at the same comfortable level?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
May the stored all-channel correction be compared at the same comfortable level?
Retain Off as the previous preference. No calibration routine or test tone is required.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Select the actual Room EQ > AccuEQ > On (All Ch) control
- If No → Stop at the unconfirmed condition

step-4
Select the actual Room EQ > AccuEQ > On (All Ch) control
Leave manual equalizers, speaker levels, crossovers and measurement controls unchanged.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Is the same passage subjectively better balanced with that already stored correction?
- If I could not do this → Stop at the unconfirmed condition

step-5
Is the same passage subjectively better balanced with that already stored correction?
The comparison does not establish a measured distortion figure or a hardware repair.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

Possible result
Checks completed — report the actual result
Completion does not automatically mean the problem is solved. Report what actually happened; no physical test or measured repair is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Stop at the unconfirmed condition
A required setup or response was not confirmed. Retain the actual observation and consult the exact source/partner manual or official support. Do not escalate to a reset, update 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 actual model, connection, partner capability and state before continuing. Do not guess a menu, interrupt an installation or modify a live source by trial and error.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
