• 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 Conexão de Energia

1. Garantir o 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. Instruções de operação

4.1 Ligar/Desligar

• Para ligar, pressione o botão LIGAR switch on the front panel. The Power LED will illuminate.
• Para desligar, pressione o LIGAR troque novamente.

4.2 Adjusting Gain Controls

• Use the detented CONTROLES DE GANHO 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 Compreendendo os indicadores LED

• LED de energia: Indica o ampO lificador está ligado.
• LED de sinal: Illuminates when an audio signal is present at the input.
• LED de clipe: 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:

• Localize o CRUZAMENTO interruptor no painel traseiro.
• In GAMA COMPLETA modo, o 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. Manutenção

• Limpeza: Limpe regularmente o exterior do ampLimpe o aspirador com um pano macio e seco. Não utilize produtos de limpeza líquidos ou solventes. Certifique-se de que as grelhas de ventilação estejam livres de poeira e detritos.
