- 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 Поврзување за напојување
- Обезбедете го amplifier's power switch on the front panel is in the OFF position.
- 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. Упатства за работа
4.1 Вклучување/исклучување
- За да го вклучите, притиснете го МОOWНОСТ ВКЛУЧЕНО switch on the front panel. The Power LED will illuminate.
- За да го исклучите, притиснете го МОOWНОСТ ВКЛУЧЕНО префрли повторно.
4.2 Adjusting Gain Controls
- Use the detented КОНТРОЛИ НА ДОБИВАЊЕ 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 Разбирање на LED индикаторите
- Напојување LED: Укажува на ampлафијаторот е вклучен.
- LED сигнал: Свети кога на влезот е присутен аудио сигнал.
- LED клип: 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:
- Лоцирајте го КРОСОВЕР прекинувач на задниот панел.
- In ЦЕЛОСЕН ОПСЕГ режим, на 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. Одржување
- Чистење: Редовно чистете ја надворешноста на amplifier with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation grilles are free from dust and debris.
- Вентилација: Always ensure proper ventilation. Do not block the air vents on the front or rear panels.
