The Crown XLS Series Power Amplifiers are designed to deliver high-performance audio for portable PA systems, combining advanced technology with affordability. These amplifiers are notable for their lightweight design, weighing under 11 pounds, which is significantly less than many competitors. The XLS Series is engineered to be powerful, flexible, and efficient, making it a versatile choice for various audio applications.
At its core, the XLS Series features a high-performance, lightweight Class-D amplifier powered by DriveCore™ Technology. This technology ensures efficient power delivery and reliable operation. A key feature of these amplifiers is the integrated PureBand™ Crossover System, which allows for seamless transitions between low and high-frequency drivers. This system offers a wide range of crossover points, from 50Hz to 3.00kHz, providing flexibility in tailoring the audio output to specific speaker configurations. The crossover system supports various modes, including LowPass Filter on Channel 1 and HighPass Filter on Channel 2, or a HighPass Filter on both channels, or a LowPass Filter on both channels. Even in bridge-mono mode, the crossover system remains active, allowing users to select either LowPass or HighPass filters.
Another crucial feature is the integrated Peakx™ Limiters. These limiters are designed to provide maximum output while simultaneously protecting speakers from damage due to excessive power. The Peakx™ Limiters are factory-shipped in the "On" configuration, but users can engage or disengage them as needed through the amplifier's menu system.
The XLS Series amplifiers offer extensive input compatibility, featuring XLR, 1/4", and RCA inputs, ensuring they can connect to virtually any audio source. The 1/4" inputs also serve as loop-thrus, allowing the signal to be distributed to additional amplifiers, which is useful in larger sound systems.
The front panel of the amplifier provides intuitive controls and indicators. Each channel has a black rotary level control for gain adjustment. An LCD screen, accompanied by "Mode/Menu," "Prev," and "Next" buttons, facilitates the configuration of the crossover system, amplifier mode, and limiter settings. The front panel also includes several LED indicators: Signal Presence (green, illuminates when input signal exceeds -40dBu), -10dB (green, flashes when output is -10dB below clip), -20dB (green, flashes when output is -20dB below clip), Clip (red, illuminates when output is overdriven), and Thermal (red, illuminates when thermal compression begins). Cooling vents on the front ensure efficient front-to-rear forced air flow. A blue LED on the power button indicates when the amplifier is turned on.
The rear panel further enhances the amplifier's versatility. It includes binding post output jacks for each channel, accommodating banana plugs or bare wire. European models come with safety plugs to prevent incorrect power plug insertion. For speaker connections, two 4-pole Speakon® output connectors are provided. The Channel 1 connector is wired for both channels, allowing for bridge-mode wiring or stereo wiring of two speakers to a single Speakon. A circuit breaker offers overload protection. Fans on the rear panel contribute to the front-to-back forced airflow, maintaining optimal operating temperatures.
The XLS Series supports multiple operating modes to suit different audio setups. The default "Stereo Bypass Mode" configures the amplifier for stereo operation with the PureBand™ Crossover System bypassed. In "Bridge-Mono Mode," the power of both amplifier channels is combined into a single 8 or 4 ohm load, ideal for driving subwoofers or other high-power applications. "Crossover Mode" utilizes a LowPass Filter on Channel 1 and a HighPass Filter on Channel 2, enabling bi-amplification. "HighPass Mode" applies a HighPass Filter to both channels at a selected frequency, while "LowPass Mode" applies a LowPass Filter to both channels at a selected frequency.
To ensure safe and correct operation, the manual emphasizes several important safety instructions, including reading all instructions, heeding warnings, and following proper installation guidelines. It also provides an FCC Compliance Notice, detailing the device's adherence to FCC rules and offering guidance on resolving potential interference issues.
Maintenance features are straightforward, primarily focusing on proper installation and operation to ensure longevity. The amplifier is designed with no user-serviceable parts inside, and all servicing is to be referred to qualified service personnel. The power cord is designed to be readily operable for disconnection from AC mains.
Crown stands behind the XLS Series with a No-Fault Fully-Transferable 3-year Warranty, protecting the investment. The manual encourages users to register their warranty and keep their bill of sale as proof of purchase. For additional information or support, users can consult Crown's Amplifier Application Guide online or contact Crown Technical Support. The XLS Series embodies Crown's commitment to delivering reliable, high-quality audio solutions for professional use.
