SSL 2+ MKII: restore a rear microphone after a front INST override
SSL 2+ MKII: restore a rear microphone after a front INST override. 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
Rear mic expected, corresponding front INST occupied; phantom already verified.
Connection scope: Analog line / headphone audio. Symptom: My microphone isn’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
Is the missing mic on the same channel as an occupied front INST jack?
The front instrument connection automatically overrides that channel mic/line path.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Can the session stop with monitoring muted before unplugging the instrument cable?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-1
Can the session stop with monitoring muted before unplugging the instrument cable?
Leave XLR microphone and its known compatible phantom setting unchanged.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Do you want the rear microphone rather than the instrument now?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-2
Do you want the rear microphone rather than the instrument now?
Removing the front source stops its channel signal.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Remove only that front INST plug
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Remove only that front INST plug
Do not unplug the microphone or change 48 V.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Does the rear microphone now register on that input meter?
- 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 rear microphone now register on that input meter?
Do not infer a damaged preamp from the previous documented override.
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.
