Informazioni sulla sicurezza

Osservare sempre le seguenti precauzioni di sicurezza per evitare scosse elettriche, incendi o danni all'unità:

• Fonte di energia: Collegare il amplificatore solo al tipo di fonte di alimentazione indicata sull'unità. Assicurarsi che il volumetage è corretto per la tua regione.
• Messa a terra: Always use a grounded power cord. Do not defeat the grounding plug.
• Ventilazione: Ensure adequate ventilation. Do not block ventilation openings. Maintain at least 2 inches (5 cm) of clear space around the amplificatore per il flusso d'aria.
• Umidità: Non esporre il amplifier to rain or moisture. Do not place objects filled with liquids on the amppiù vivace.
• Manutenzione: Non tentare di riparare l'unità da soli. Per qualsiasi intervento di assistenza, rivolgersi a personale qualificato.
• Sovraccarico: Evitare di utilizzare il amplifier at excessive volume levels for extended periods, which can cause hearing damage or damage to connected speakers.

Caratteristiche principali

The QSC RMX850 Power Amplifier offers a robust set of features for professional audio applications:

• Dimensioni compatte: Designed for efficient use of rack space.
• Ingressi versatili: Features 1/4" (6.3mm) TRS, XLR, and barrier strip balanced inputs for broad compatibility.
• Uscite flessibili: Equipped with binding post and Neutrik Speakon outputs.
• Front-Mounted Controls: Gain controls are conveniently located on the front panel for easy access and adjustment.
• Selectable Low-Frequency Filters: Includes 30 Hz or 50 Hz low-frequency filters to protect speakers and increase headroom.

Impostare

1. Disimballaggio e ispezione

Rimuovere con attenzione il file amplifier from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. If damage is found, contact your dealer immediately.

2. Posizionamento e montaggio

The RMX850 is designed for standard 19-inch rack mounting. Ensure the rack provides adequate ventilation. If not rack-mounted, place the amplifier on a stable, level surface, ensuring that the ventilation grilles are not obstructed.

3. Connessioni

Prima di effettuare qualsiasi collegamento, assicurarsi che amplifier è spento e scollegato dalla presa CA.

• Connessioni di ingresso: Collega la tua sorgente audio (mixer, preamplifier) ​​al amplifier's input jacks. The RMX850 provides XLR, 1/4" TRS, and barrier strip connectors for balanced input signals. Use high-quality shielded cables.
• Connessioni di uscita: Collega i tuoi altoparlanti a amplifier's output terminals. The RMX850 features both Neutrik Speakon and binding post outputs. Ensure correct polarity (+ to + and - to -) for all speaker connections. Verify that your speakers' impedance matches the amplifier's specifications (e.g., 4 ohms or 8 ohms per channel).
• Collegamento elettrico: Once all audio connections are made, connect the supplied AC power cord to the amplifier's power inlet and then to a grounded AC outlet.

4. DIP Switch Settings (Rear Panel)

The RMX850 features DIP switches on the rear panel to configure various settings, including low-frequency filters and operating modes (stereo, parallel, bridge). Consult the detailed diagram on the amplifier's rear panel or a more comprehensive technical manual for specific configurations. Ensure these are set correctly for your application before powering on.

Operare il Amppiù vivace

1. Accensione

After all connections are secure and verified, turn the gain controls on the front panel fully counter-clockwise (minimum). Then, press the power switch to turn on the amplificatore. Il LED indicatore di alimentazione si illuminerà.

2. Adjusting Gain

Slowly turn the gain controls clockwise for each channel until the desired volume level is achieved. Monitor the signal and clip indicator LEDs:

• SEGNALE LED: Si illumina quando è presente un segnale audio.
• LED CLIP: Si illumina quando il amplifier output is clipping (distorting). Reduce the gain immediately if this LED lights up frequently or stays on. Occasional, brief flashes on dynamic peaks are acceptable, but continuous illumination indicates severe clipping and potential damage to speakers.

3. Low-Frequency Filters

The selectable low-frequency filters (30 Hz or 50 Hz) help protect speakers from damaging sub-sonic frequencies and improve overall system headroom. Engage these filters via the DIP switches on the rear panel as needed for your speaker system.

Manutenzione

The QSC RMX850 Power Amplifier is designed for reliable operation with minimal maintenance. However, regular care will ensure its longevity:

• Pulizia: Utilizzare un panno morbido e asciutto per pulire la parte esterna del amplificatore. Non utilizzare detergenti abrasivi o solventi.
• Ventilazione: Periodically check that the ventilation grilles are free from dust and debris. Use a soft brush or vacuum cleaner to remove any accumulation.
• Connessioni: Occasionally check all input and output connections to ensure they are secure.
