• Connect your loudspeakers to the corresponding Channel 1 and Channel 2 outputs. Verify that the impedance of your speakers matches the amplifier's capabilities (4 ohms or 8 ohms).

3.4 Conexiune la alimentare

1. Asigurați amplifier's power switch on the front panel is in the OFF position.
2. Connect the supplied AC power cord to the AC INLET on the rear panel of the amplifier and then to a grounded AC power outlet.

4. Instrucțiuni de utilizare

4.1 Pornire/Oprire

• Pentru a porni, apăsați tasta APRINDE switch on the front panel. The Power LED will illuminate.
• Pentru a opri, apăsați tasta APRINDE comuta din nou.

4.2 Adjusting Gain Controls

• Use the detented Câștigați CONTROALE on the front panel for Channel 1 and Channel 2 to adjust the input sensitivity.
• Start with the gain controls set to their minimum position (fully counter-clockwise) before playing audio.
• Gradually increase the gain until the desired volume level is achieved without the Clip LED illuminating frequently.

4.3 Înțelegerea indicatorilor LED

• LED de alimentare: Indică ampLifierul este pornit.
• LED semnal: Se aprinde când este prezent un semnal audio la intrare.
• LED clip: Illuminates when the output signal is clipping (distorting). Reduce the input level or gain if this LED lights up frequently.

4.4 Using the Subwoofer/Satellite Crossover

The GX5 features a built-in crossover for optimized speaker performance:

• Localizați ÎNcrucișarea comutatorul de pe panoul din spate.
• In GAMĂ COMPLETĂ modul, amplifier outputs the full audio spectrum to both channels.
• In SUB/SAT mode, Channel 1 outputs frequencies from 20 Hz to 100 Hz (for subwoofers), and Channel 2 outputs frequencies from 100 Hz to 20 kHz (for full-range speakers). Adjust front panel gain controls to balance subwoofer and top box levels.

5. Întreținere

• curatenie: Curățați în mod regulat exteriorul ampCurățați aparatul cu o cârpă moale și uscată. Nu utilizați agenți de curățare lichizi sau solvenți. Asigurați-vă că grilele de ventilație sunt fără praf și resturi.
• Ventilare: Always ensure proper ventilation. Do not block the air vents on the front or rear panels.
