SSL 2+ MKII: select LINE for an already connected rear-jack line source
SSL 2+ MKII: select LINE for an already connected rear-jack line source. 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 keyboard/synth line-level source in rear jack; LINE currently unpressed.
Connection scope: Analog line / headphone audio. Symptom: Buttons, touch controls or wear detection aren’t working.
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 the source manual confirm line-level output to the rear jack?
Front INST and rear XLR are different signal paths; unknown wiring stops here.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Is LINE confirmed unpressed with no front INST override?
- 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 LINE confirmed unpressed with no front INST override?
Do not blindly toggle a mode already correct.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → May the input mode change with monitors low and no recording active?
- 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 input mode change with monitors low and no recording active?
The available gain range changes with LINE mode.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Engage LINE on that source channel
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Engage LINE on that source channel
Leave 48 V off for the line-level source and leave other channel settings untouched.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Does the expected line source meter respond without overload?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-4
Does the expected line source meter respond without overload?
Recheck gain gently instead of assuming the previous gain correct.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Checks completed — report what happened

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
