2. Sikkerhedsoplysninger

Overhold altid følgende sikkerhedsforanstaltninger for at forhindre elektrisk stød, brand eller beskadigelse af enheden.

• Strømkilde: Tilslut amplifier only to the type of power source indicated on the unit.
• Jording: Sørg for amplifier is properly grounded to prevent electrical shock.
• Ventilation: Bloker ikke ventilationsåbningerne. Sørg for tilstrækkelig luftgennemstrømning omkring enheden for at forhindre overophedning.
• Fugtighed: Udsæt ikke amplifier to rain or moisture. Do not place objects filled with liquids on the unit.
• Service: Overlad al service til kvalificeret servicepersonale. Forsøg ikke selv at servicere dette produkt.
• Placering: Placer amplifier on a stable surface or mount it securely in a rack.

3. Opsætning

3.1 Rackmontering

The QSC RMX1450a requires 2 standard rack spaces for installation. Secure the amplifier firmly using appropriate rack screws. Ensure there is sufficient space for airflow around the unit, especially at the front and rear ventilation grilles.

3.2 Forbindelser

Før du foretager nogen tilslutninger, skal du sørge for, at amplifier is powered off and disconnected from the mains supply.

3.2.1 Indgangsforbindelser

The RMX1450a offers flexible input options for each channel:

• 1/4" TRS: For balanced or unbalanced line-level signals.
• XLR: For balanced line-level signals, commonly used in professional audio setups.
• Barrier Strip: Provides an alternative connection method for balanced or unbalanced signals, often used for permanent installations.

Tilslut din lydkilde (mixer, forforstærker)amplifier, etc.) to the desired input connectors for Channel 1 and Channel 2.

3.2.2 Udgangsforbindelser

Tilslut dine højttalere til amplifier's output terminals:

• Bindende indlæg: Standard screw-type terminals for bare wire or banana plug connections.
• Neutrik Speakon: Secure, high-current connectors ideal for professional loudspeaker connections.

Ensure correct polarity (+ to + and - to -) when connecting speakers. Refer to your speaker's manual for impedance compatibility.

3.2.3 Strømtilslutning

Tilslut det medfølgende netkabel til amplifier's IEC inlet and then to a grounded electrical outlet.

4. Betjeningsvejledning

4.1 Kontrol og indikatorer på frontpanelet

Figur 4.1: Vinklet front view of the QSC RMX1450a Stereo Power Amplifier, showing the power switch, channel gain controls, and LED indicators.

• Afbryderen: Skifter mellem amplifner til og fra.
• Gain Controls (Channel 1 & 2): Front-mounted rotary controls for adjusting the input sensitivity (volume) of each channel.
• Signal LED'er: Illuminate when an audio signal is present at the input.
• Klip LED'er: Illuminate when the output signal is approaching clipping (distortion). Reduce gain if these LEDs light frequently.

4.2 Rear Panel Switches

The rear panel features several switches to configure the ampLifierens drift:

• Clip Limiters: Independent and defeatable clip limiters prevent severe clipping and protect speakers. It is generally recommended to keep these engaged.
• Filtre: High-pass filters (e.g., 30 Hz or 50 Hz) can be engaged to remove unwanted low-frequency content, protecting speakers and improving clarity.
• Modeskift:
  • Stereoanlæg: Default mode, each channel operates independently.
  • Parallel: Both channels receive the same input signal, but drive separate speakers. Useful for bi-amping or driving multiple speakers with a mono source.
  • Bridge Mono: Combines both channels into a single, higher-power mono output. Use only with speakers rated for bridged operation and connect to the designated bridged output terminals.

4.3 Grundlæggende betjeningssekvens

1. Ensure all connections (inputs, outputs, power) are secure and correct.
2. Indstil amplifier's gain controls to their minimum (fully counter-clockwise) position.
3. Power on your audio source (mixer, etc.) first.
4. Power on the QSC RMX1450a amplivligere.
5. Slowly increase the gain controls on the amplifier to achieve the desired volume level. Monitor the Signal and Clip LEDs.
6. When powering down, turn the amplifier off first, then your audio source.

5. Vedligeholdelse

The QSC RMX1450a amplifier is designed for robust performance with minimal maintenance.

• Rensning: Periodically wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Ventilation: Ensure ventilation grilles remain clear of dust and debris to maintain proper cooling.
• Inspektion: Regularly check power cords and audio cables for any signs of damage.
