5.2.1 Collegamenti di ingresso
IL amplifier features electronically balanced RCA and XLR inputs for each channel (Channel A and Channel B). Connect your audio source (e.g., mixer, preamplifier) to these inputs.
- Ingressi RCA: For unbalanced audio signals.
- Ingressi XLR: For balanced audio signals, recommended for longer cable runs to minimize noise.
A user-selectable input sensitivity switch allows you to choose between 0.775V and 1.4V, matching the output level of your source equipment.
5.2.2 Collegamenti di uscita
Collega i tuoi altoparlanti passivi a amplifier's outputs using Speakon or binding post connectors.
- Speakon Outputs: For secure and reliable speaker connections.
- Binding Post Outputs: Compatible with bare wire, banana plugs, or spade connectors.
5.3 Selezione della modalità
IL amplifier supports three operating modes, selectable via a switch on the rear panel:
- Modalità stereo: Each channel operates independently, providing separate left and right audio signals to two speakers.
- Modalità parallela: Both channels receive the same input signal but drive separate speakers. This is useful for driving multiple speakers with a mono source.
- Modalità Bridge-Mono: Combines the power of both channels into a single, higher-power output for driving a single, high-power speaker (e.g., a subwoofer). Ensure the speaker's impedance is compatible with the bridged output.
5.4 Low-Pass Filter
IL amplifier includes a low-pass filter switch. When activated, this filter will only pass frequencies below 80Hz to the connected speakers. This is particularly useful when powering subwoofers, ensuring they only reproduce low-frequency content.

6. Istruzioni per l'uso
6.1 Comandi e indicatori del pannello frontale
The front panel provides essential controls and visual indicators for monitoring ampstato di lificatore.
- Interruttore di alimentazione: Gira il amplificatore acceso o spento.
- Controlli di livello: Adjust the output volume for Channel A and Channel B independently.
- LED di potenza: Si illumina quando il amplifier è acceso.
- LED di segnalazione: Illuminates when an audio signal is present on the respective channel.
- LED clip: Illuminates when the output signal is clipping, indicating potential distortion. Reduce the input level or amplifier gain to prevent clipping.
- LED di guasto: Si illumina se il amplifier enters protection mode due to an issue (e.g., short circuit, overheating, impedance mismatch).
Display LCD 6.2
The integrated LCD display provides real-time information about each channel:
- Decibel (dB) Level: Shows the current output level for Channel A and Channel B. Adjust the level controls to modify this.
- Temperatura: Displays the operating temperature of each channel, allowing you to monitor for potential overheating.
6.3 Potenza in uscita
The Crown XLi1500 delivers the following power outputs:
- Dual Channel, 4 Ohm: 450 Watt per canale
- Dual Channel, 8 Ohm: 330 Watt per canale
- Bridge-Mono, 8 Ohm: 900 Watt totali
7. Manutenzione
Per garantire la longevità e le prestazioni ottimali del tuo amplifier, seguire queste linee guida per la manutenzione:
- Pulizia: Utilizzare un panno morbido e asciutto per pulire la parte esterna del amplifier. Avoid liquid cleaners or solvents.
- Ventilazione: Regularly check that the forced-air cooling vents are clear of dust and obstructions. Proper airflow is crucial to prevent overheating.
- Magazzinaggio: Conservare il amplifier in a cool, dry environment away from direct sunlight and extreme temperatures.
8. Risoluzione Dei Problemi
Se riscontri problemi con il tuo amplifier, prendere in considerazione i seguenti passaggi comuni per la risoluzione dei problemi:
- Nessun potere: Assicurarsi che il cavo di alimentazione sia collegato saldamente e che l'interruttore di alimentazione sia acceso. Controllare la presa di corrente.
- Nessun suono: Verify all input and output cables are correctly connected. Check the input sensitivity setting and ensure the level controls are not set to minimum. Confirm the operating mode (Stereo, Parallel, Bridge-Mono) is appropriate for your setup.
- Distorted Sound (Clip LED On): Reduce the input signal level from your source or lower the amplifier's level controls until the Clip LED no longer illuminates.
- Protect LED On: Questo indica il amplifier has entered protection mode. Power off the unit, check all speaker connections for short circuits, ensure speaker impedance is within the amplifier's specifications, and allow the unit to cool down if it's hot. Restart after resolving the issue.
- Excessive Heat (High Temperature on LCD): Ensure the cooling vents are unobstructed and the amplifier has adequate airflow. Reduce the load or operating volume if necessary.
