When this guide applies

Both original surrounds already play, but their relative balance is unwanted; no missing link or physical dead channel.

Connection scope: Device controls / power only. Symptom: Sound plays from only one side.

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

Do both configured surround speakers already reproduce suitable material, with only their relative level unwanted?

A silent/unlinked speaker or a programme with no surround content has another path.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-1

Is the existing surround balance preference known rather than an installer setting you must preserve?

Retain the actual old state; do not guess a zero or a range absent from this manual.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-2

May one small relative-balance trial be compared at a comfortable level?

The relative level can move in either direction; reverse the one step if worse.

Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.

step-3

Hold SURR on the supplied remote for two seconds

A short press changes their common level instead of balance.

Look for: Perform only the stated operation, then confirm it was possible.

step-4

Make one small relative-balance adjustment with the actual + or − control

Observe the display and use the direction matching the intended balance; stop if its meaning is unclear.

Look for: Perform only the stated operation, then confirm it was possible.

step-5

Is that same suitable passage better balanced between the two surrounds?

This preference trial is not a hardware or calibration test.

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.
