• Подключите источник звука к Канал 1 и Канал 2 inputs using XLR, 1/4-inch balanced, or phono (RCA) cables. Ensure secure connections.
• For stereo operation, connect the left channel of your source to Channel 1 and the right channel to Channel 2.

3.3 Connecting Loudspeakers

The GX5 provides versatile output options for connecting your loudspeakers:

• Speakon / 1/4-inch (TS) Combo Outputs: Use Speakon connectors for secure, high-power connections. These outputs also accept 1/4-inch TS plugs.
• Обязательные посты: For other speaker wiring systems, use the binding posts. Ensure correct polarity (+ to + and - to -).
• 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 Подключение питания

1. Обеспечить 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. Инструкция по эксплуатации

4.1 Включение/выключение питания

• Для включения нажмите кнопку ВКЛЮЧИТЬ switch on the front panel. The Power LED will illuminate.
• Чтобы выключить питание, нажмите кнопку ВКЛЮЧИТЬ снова переключитесь.

4.2 Adjusting Gain Controls

• Use the detented УСИЛЕНИЕ КОНТРОЛЯ 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. Понимание светодиодных индикаторов

• Светодиод питания: Указывает на ampЛифер включен.
• Сигнальный светодиод: Индикатор загорается, когда на вход поступает аудиосигнал.
• Светодиод зажима: 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:

• Найдите КРОССОВЕР переключатель на задней панели.
• In ПОЛНЫЙ СПЕКТР режим, 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. Техническое обслуживание

• Уборка: Регулярно очищайте внешнюю поверхность ampПротрите фильтр мягкой сухой тканью. Не используйте жидкие чистящие средства или растворители. Убедитесь, что вентиляционные решетки очищены от пыли и мусора.
• Вентиляция: Always ensure proper ventilation. Do not block the air vents on the front or rear panels.
