5.2 Priključitev zvočnikov

1. Zagotovite amplifier is turned OFF and unplugged from the power outlet.
2. Connect your passive speakers to the speaker output terminals on the rear panel.
3. Match the speaker impedance (4Ω or 8Ω) to the corresponding terminals on the amplifier.
4. Pozitivni (+) priključek zvočnika priključite na pozitivni (+) priključek ampnapajalnika in negativni (-) priključek zvočnika na negativni (-) priključek amplifier. Ensure secure connections.

5.3 Priklop avdio virov

1. Connect your audio source (e.g., CD player, PC, streamer) to either the 'CD' or 'PC' RCA input jacks on the rear panel using appropriate RCA cables.
2. Ensure left (L) and right (R) channels are correctly connected.

5.4 Napajalni priključek

1. After all audio and speaker connections are made, connect the supplied power cord to the power input socket on the rear panel.
2. Plug the other end of the power cord into a 100V AC power outlet.

6. Navodila za uporabo

1. Vklop: Turn the Power Switch on the front panel to the 'ON' position. The tubes will begin to glow, indicating the amplifier is warming up. Allow a few moments for the tubes to stabilize before playing audio.
2. Izberite vnos: Use the Input Selector Switch on the rear panel to choose between the 'PC' or 'CD' audio input, corresponding to your connected source.
