SSL 2+ MKII: center a mono source currently monitored in STEREO
SSL 2+ MKII: center a mono source currently monitored in STEREO. 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 mono input sent to one ear by the hardware STEREO mode.
Connection scope: USB audio. 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
Is this a single mono source rather than a stereo pair?
A stereo keyboard should retain its intended left/right image.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Is the STEREO switch currently pressed?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-1
Is the STEREO switch currently pressed?
If mode is unknown, stop rather than toggle and guess.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → May the direct-monitor image change with levels low?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-2
May the direct-monitor image change with levels low?
Both independent sources will be centered when STEREO is unpressed.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Release STEREO to its unpressed state
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Release STEREO to its unpressed state
Leave DAW pan and input gain unchanged.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Is that mono live input centered in the monitoring image?
- 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 that mono live input centered in the monitoring image?
This does not diagnose a physically failed headphone side.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Checks completed — report what happened
- If No / cannot confirm → Keep these observations for official support

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.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
