3. Ensure all connections are secure to prevent signal loss or intermittent operation.

5.3 Strømtilslutning

Before connecting power, ensure the ampStrømafbryderen er i OFF-positionen.

1. Connect the supplied AC power cord to the AC power inlet on the rear panel of the amplivligere.
2. Sæt den anden ende af netledningen i en jordet stikkontakt.
3. Verify that the power source matches the voltage krav i amplifier (100V or 70V, as specified).

6. Betjeningsvejledning

Follow these steps for safe and effective operation of your Ashly ne8250 amplivligere.

6.1 Tænd
