4. Podešavanje
4.1 Fizički smještaj
The QSC GX3 amplifier is designed for rack mounting. Ensure sufficient space for airflow, especially around the front and rear ventilation grilles. Avoid placing the unit near heat sources or in direct sunlight.

4.2 Veze
Prije bilo kakvog povezivanja, provjerite amplifier is powered off and disconnected from the AC mains.
Figure 4.2: Rear panel of the QSC GX3 Power Amplifier, illustrating input and output connections.
- Audio ulazi: Povežite svoj audio izvor (mikser, predpojačalo)amplifier) to the input connectors on the rear panel. The GX3 features XLR and RCA input options for each channel.
- Izlazi za zvučnike: Connect your loudspeakers to the output connectors. The amplifier provides both NL4 (Speakon-compatible) and binding post outputs. Ensure correct polarity (+ to + and - to -).
- Crossover prekidač: 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-amplifikovani sistemi.
- AC napajanje: 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.
5. Operativni
5.1 Kontrole i indikatori na prednjoj ploči
Figure 5.1: Front panel of the QSC GX3 Power Amplifier, showing the power switch, gain controls, and status indicators.
- POWER ON Switch: Uključuje ampsnaga spasioca.
- 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 indikatori: 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.
- PWR indikator: Zelena LED koja označava ampLifier je uključen.
5.2 Uključivanje i početna provjera zvuka
- Provjerite jesu li sve veze ispravne i sigurne.
- Postavite 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.
- Polako povećavajte kontrole pojačanja na amplifier to achieve the desired listening level. Observe the SIG indicators for signal presence and the CLIP indicators to avoid distortion.
- When powering down, turn off the amplifier first, then your audio source equipment.
6. Održavanje
Redovno održavanje osigurava optimalne performanse i dugotrajnost vašeg amplifier.
- čišćenje: Koristite meku, suhu krpu za čišćenje spoljašnjosti ampNe koristite tekuća sredstva za čišćenje ili rastvarače.
- ventilacija: Periodically check that the ventilation grilles are free from dust and debris. Blocked vents can lead to overheating.
- Veze: Occasionally check all input and output connections for tightness and corrosion.
7. Otkrivanje problema
Ako naiđete na probleme sa svojim QSC GX3 ampspasilac, pogledajte sljedeće uobičajene probleme i rješenja:
| Problem | Mogući uzrok | Rješenje |
|---|---|---|
| Nema snage | Power cord disconnected; circuit breaker tripped; power switch off. | Check power cord connection; reset circuit breaker on rear panel; ensure power switch is ON. |
| Nema izlaza zvuka | Ulazni kablovi isključeni; kablovi zvučnika isključeni ili pogrešan polaritet; kontrole pojačanja postavljene prenisko; problem s izvorom zvuka. | Verify all audio input and speaker connections; increase gain controls; check audio source functionality. |
| Distorted Sound / CLIP LED On | Ulazni signal previsok; amplifier overloaded; speaker impedance mismatch. | Reduce input level from source; lower amplifier gain; ensure speaker impedance is within amplifier's rated range. |
| Pregrijavanje | Blocked ventilation; inadequate airflow; prolonged high-power operation. | Ensure clear ventilation paths; provide adequate space around the unit; reduce operating level if necessary. |
Ako problem i dalje postoji nakon isprobavanja ovih rješenja, obratite se korisničkoj podršci QSC-a ili kvalificiranom servisnom tehničaru.
