When this guide applies

Exact Scarlett 2i2 4th Gen or Scarlett Solo 4th Gen, not earlier generations. For Solo, Air applies only to the microphone input. Exact Focusrite Scarlett 2i2 4th Gen. Quiet playback only at the headphones, correct TRS path already verified, headphone exact specification available. No maximum-volume test or amplifier-power claim. Only normal external user controls; no reset, firmware installation, internal repair, mains alteration or earth lifting.

Connection scope: USB audio. Symptom: Playback is too quiet or uneven.

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 scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.

scope

Confirm the exact setup

Is playback quiet through correctly connected TRS headphones, with their exact model and impedance specification available, while you want a read-only compatibility check?

Look for: Choose only a detail you can confirm.

Identify the actual headphone impedance

Read the impedance from the exact headphone maker’s documentation. Do not infer it from plug size or substitute another model’s specification.

Look for: Perform this one check and observe the actual response.

Compare with Focusrite’s stated recommendation

Compare that value with the interface manual recommendation of headphones up to 300 ohms. Do not increase volume to test a limit; sensitivity and programme level also affect loudness.

Possible result

Confirm the unknown detail before proceeding

Stop rather than infer an installed cartridge, partner, source level, cable capability, software version or control state.

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

    Possible result

    Keep the actual observation for support

    Record the exact model, source, connection, control state and response. These checks do not diagnose a failed component or prescribe a reset, update, internal repair or mains change.
