5.2.1 Connexions d'entrada
El 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.
- Entrades RCA: For unbalanced audio signals.
- Entrades 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 Connexions de sortida
Connecteu els vostres altaveus passius al 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 Selecció del mode
El amplifier supports three operating modes, selectable via a switch on the rear panel:
- Mode estèreo: Each channel operates independently, providing separate left and right audio signals to two speakers.
- Mode paral·lel: Both channels receive the same input signal but drive separate speakers. This is useful for driving multiple speakers with a mono source.
- Bridge-Mono Mode: 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
El 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. Instruccions de funcionament
6.1 Controls i indicadors del tauler frontal
The front panel provides essential controls and visual indicators for monitoring ampestat de lifier.
- Interruptor d'alimentació: Gira el ampmés viu encès o apagat.
- Controls de nivell: Adjust the output volume for Channel A and Channel B independently.
- LED d'alimentació: S'il·lumina quan el ampel lifier està encès.
- LED de senyal: Illuminates when an audio signal is present on the respective channel.
- LED de clip: Illuminates when the output signal is clipping, indicating potential distortion. Reduce the input level or amplifier gain to prevent clipping.
- LED d'error: S'il·lumina si el amplifier enters protection mode due to an issue (e.g., short circuit, overheating, impedance mismatch).
6.2 Pantalla LCD
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 Potència de sortida
The Crown XLi1500 delivers the following power outputs:
- Dual Channel, 4 Ohm: 450 watts per canal
- Dual Channel, 8 Ohm: 330 watts per canal
- Bridge-Mono, 8 Ohm: 900 watts en total
7. Manteniment
Per garantir la longevitat i el rendiment òptim del vostre amplificador, seguiu aquestes pautes de manteniment:
- Neteja: Utilitzeu un drap suau i sec per netejar l'exterior amplifier. Avoid liquid cleaners or solvents.
- Ventilació: Regularly check that the forced-air cooling vents are clear of dust and obstructions. Proper airflow is crucial to prevent overheating.
- Emmagatzematge: Emmagatzemar el amplifier in a cool, dry environment away from direct sunlight and extreme temperatures.
8. Solució De Problemes
Si teniu problemes amb el vostre amplifier, consider the following common troubleshooting steps:
- Sense energia: Ensure the power cable is securely connected and the power switch is on. Check the power outlet.
- Sense so: 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: Això indica el 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.
