3. Uppsetning

Proper setup is crucial for the safe and efficient operation of your QSC GX5 ampFylgdu þessum skrefum vandlega:

3.1 Upptaka og staðsetning

1. Fjarlægðu varlega ampFjarlægið úðann úr umbúðunum. Geymið öll umbúðaefni til síðari flutnings eða geymslu.
2. Settu amplifier in a well-ventilated area. Ensure adequate airflow around the unit to prevent overheating. Avoid placing it near heat sources or in direct sunlight.
3. The GX5 is designed for rack mounting. Secure it in a standard 19-inch equipment rack using appropriate rack screws.

• Tengdu hljóðgjafann þinn við Rás 1 og Rás 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.
• Bindandi færslur: 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 Rafmagnstenging

1. Tryggðu að 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. Notkunarleiðbeiningar

4.1 Kveikt/slökkt

• Til að kveikja á, ýttu á Kveikt er á switch on the front panel. The Power LED will illuminate.
• Til að slökkva á, ýttu á Kveikt er á skipta aftur.

4.2 Adjusting Gain Controls

• Use the detented FYRIR STJÓRN 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 Að skilja LED-ljós

• Power LED: Gefur til kynna ampkveikt er á lyftaranum.
• Merki LED: Lýsir þegar hljóðmerki er til staðar við inntakið.
• Clip 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:

• Finndu KROSSOVER rofanum á bakhliðinni.
• In FULLT SVÆÐI háttur, 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. Viðhald

• Þrif: Hreinsaðu reglulega að utan ampÞurrkið af með mjúkum, þurrum klút. Notið ekki fljótandi hreinsiefni eða leysiefni. Gangið úr skugga um að loftræstigrindur séu lausar við ryk og rusl.
• Loftræsting: Always ensure proper ventilation. Do not block the air vents on the front or rear panels.
• Rafmagnssnúra: Inspect the power cord periodically for any damage. If damaged, replace it with an authorized QSC replacement part.
