• Priključite vir zvoka na Kanal 1 in Kanal 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.
• Zavezujoče objave: 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 Napajalni priključek

1. Zagotovite 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.

4.1 Vklop/izklop

• Za vklop pritisnite VKLOP switch on the front panel. The Power LED will illuminate.
• Za izklop pritisnite VKLOP znova preklopite.

4.2 Adjusting Gain Controls

• Use the detented NADZOR SISTEMA 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 Razumevanje LED indikatorjev

• LED za napajanje: Označuje amplifier je vklopljen.
• Signalna LED: Sveti, ko je na vhodu prisoten zvočni signal.
• Sponka LED: 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:

• Poiščite CROSSOVER stikalo na zadnji plošči.
• In POPOLNI RAN način, the 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. Vzdrževanje

• Čiščenje: Redno čistite zunanjost ampObrišite z mehko, suho krpo. Ne uporabljajte tekočih čistil ali topil. Prepričajte se, da so prezračevalne rešetke brez prahu in umazanije.
• Prezračevanje: Always ensure proper ventilation. Do not block the air vents on the front or rear panels.
• Napajalni kabel: Inspect the power cord periodically for any damage. If damaged, replace it with an authorized QSC replacement part.

6. Odpravljanje težav

If you encounter issues with your QSC GX5 ampza odpravljanje težav glejte naslednje pogoste korake:

• Brez napajanja:
  • Preverite, ali je napajalni kabel varno priključen na oba amplifier in AC vtičnico.
  • Verify that the AC outlet is functional.
  • Ensure the front panel power switch is pressed to the ON position.
• Ni zvoka:
  • Preverite, ali je vir zvoka aktiven in oddaja signal.
  • Check all input and output cable connections for security and correct polarity.
  • Zagotovite amplifier's gain controls are not set to minimum.
  • Verify that the speakers are properly connected and functional.
• Distorted Sound (Clip LED frequently on):
  • Reduce the input level from your audio source.
  • Lower the gain controls on the amplifier.
  • Ensure the speaker impedance is within the ampdoločeno območje življenjske enote.
• Overheating (GuardRail activation):
  • Poskrbite za ustrezno prezračevanje okolice amplifier. Clear any obstructions from the air vents.
  • Reduce the operating volume or allow the amplifier, da se ohladi.
