- Intrări audio: Conectați sursa audio (mixer, preamplificator)amplifier) to the input connectors on the rear panel. The GX3 features XLR and RCA input options for each channel.
- Ieșiri difuzoare: Connect your loudspeakers to the output connectors. The amplifier provides both NL4 (Speakon-compatible) and binding post outputs. Ensure correct polarity (+ to + and - to -).
- Comutator crossover: The rear panel includes a crossover switch. Set it to "FULL RANGE" for standard operation or "LP CROSSOVER HF" for low-pass filtering on channel 1 and high-pass filtering on channel 2, typically used for bi-ampsisteme lificate.
- Putere AC: Once all audio connections are secure, connect the supplied AC power cord to the AC INLET on the rear panel and then to a grounded electrical outlet.

Figure 5.1: Front panel of the QSC GX3 Power Amplifier, showing the power switch, gain controls, and status indicators.
- POWER ON Switch: Comută ampputerea lifierului.
- Gain Controls (1 & 2): Rotary knobs to adjust the output level for each channel. Start with these set to minimum (fully counter-clockwise) before powering on.
- CLIP Indicators: Red LEDs that illuminate when the output signal is clipping. Reduce the input level or gain if these light up frequently.
- SIG Indicators: Green LEDs that light up when an audio signal is present on the respective channel.
- Indicator PWR: LED verde care indică ampLifierul este pornit.
5.2 Powering On and Initial Sound Check
- Asigurați-vă că toate conexiunile sunt corecte și sigure.
- Setați amplifier's gain controls to their minimum position.
- Power on your audio source equipment first, then the QSC GX3 amplifier using the front panel POWER ON switch.
- Măriți încet controalele de amplificare de pe amplifier to achieve the desired listening level. Observe the SIG indicators for signal presence and the CLIP indicators to avoid distortion.
- Când opriți alimentarea, opriți amplifier first, then your audio source equipment.
6. Întreținere
Regular maintenance ensures optimal performance and longevity of your ampmai în viață.
- curatenie: Utilizați o cârpă moale și uscată pentru a curăța exteriorul ampNu utilizați agenți de curățare lichizi sau solvenți.
- Ventilare: Periodically check that the ventilation grilles are free from dust and debris. Blocked vents can lead to overheating.
- Conexiuni: Occasionally check all input and output connections for tightness and corrosion.
7. Depanare
If you encounter issues with your QSC GX3 amplifier, consultați următoarele probleme și soluții comune:
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| Fără putere | Power cord disconnected; circuit breaker tripped; power switch off. | Check power cord connection; reset circuit breaker on rear panel; ensure power switch is ON. |
| Fără ieșire de sunet | Input cables disconnected; speaker cables disconnected or incorrect polarity; gain controls set too low; audio source issue. | Verify all audio input and speaker connections; increase gain controls; check audio source functionality. |
| Distorted Sound / CLIP LED On | Semnal de intrare prea mare; amplifier overloaded; speaker impedance mismatch. | Reduceți nivelul de intrare de la sursă; reduceți amplifier gain; ensure speaker impedance is within amplifier's rated range. |
| Supraîncălzire | Blocked ventilation; inadequate airflow; prolonged high-power operation. | Ensure clear ventilation paths; provide adequate space around the unit; reduce operating level if necessary. |
If the problem persists after attempting these solutions, contact QSC customer support or a qualified service technician.
