When this guide applies

Exact Audio-Technica AT-LP70XBT. 33⅓/45 only; no cartridge substitution for 78 rpm or drive calibration. Only normal external user controls; no mains modification, chassis opening, reset or firmware installation.

Connection scope: Turntable / phono audio. Symptom: The record plays at the wrong speed.

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.
