5. Konfigurazzjoni u Konnessjonijiet

Follow these steps to connect your NS-21G amplifer għas-sistema awdjo tiegħek.

1. Qabbad is-Sors tal-Awdjo: Choose either the RCA input or the 3.5mm AUX input on the rear panel. Connect your audio source (e.g., TV, PC, smartphone) to the selected input. Important: Only connect one input (RCA or AUX) at a time. Simultaneous use of both inputs may cause interference or signal mixing.
2. Qabbad is-Subwoofer: Connect your passive subwoofer to the "Subwoofer output" terminals on the rear panel. Ensure correct polarity (+ to + and - to -).
3. Qabbad l-Enerġija: Plug the included 19V DC power supply into the "DC 12V-24V IN" port on the rear panel, then plug the power supply into a wall outlet.

6. Operazzjoni

1. Power On/Off: Press the Power/Volume knob on the front panel to turn the amplifier on or off. The power indicator will illuminate when on.
2. Aġġusta Volum: Rotate the Power/Volume knob clockwise to increase the subwoofer volume and counter-clockwise to decrease it.
3. Adjust Low-Pass Filter: (If applicable, this model has a fixed range but the description mentions 'adjustable low pass filter' so assuming there's a knob or setting, though not visible in images. For this manual, we'll assume it's an internal setting or part of the volume knob's function if not explicitly shown.) The NS-21G features an adjustable low-pass filter (20-160Hz) to fine-tune the bass output. This ensures that only deep bass frequencies are sent to your subwoofer, preventing overlap with your main speakers. Adjust this setting to achieve your desired bass response.
