Crown - XLi 2500 2 x 750W Power Amplifier - Black

The Nero HTX4150 is a 4-channel Class D power amplifier rated at 175W per channel into 4 ohms and 100W per channel into 8 ohms with all channels driven, not the single-channel figures most competitors publish. Adjacent channels can be bridged to produce 2 x 400W into 8 ohms, or 1 x 400W plus 2 x 175W, so a single chassis handles several system layouts. Two bridged channels can also serve as a subwoofer amplifier with frequency crossover and level control. A 105dB A-weighted signal-to-noise ratio at rated power gives the amplifier exceptional dynamic range, and 10Hz to 30kHz frequency response covers the full audible band with margin at both ends. Fan-assisted cooling keeps the chassis running cool in confined spaces such as an equipment rack or credenza, while a switching power supply rejects RF interference from nearby electronics. RCA inputs, a 12V trigger, per-channel status LEDs and a ground terminal for troubleshooting hum complete the package.

The CDi Series amplifiers are professional tools designed and built for installed sound applications. The series includes four models which are identical except for output power: CDi 1000, CDi 2000, CDi 4000, and CDi 6000. All are rugged and lightweight. CDi-Series amplifiers feature an intuitive front-panel LCD screen to guide installers through their configurations. CDi amplifiers also offer onboard DSP for loudspeaker signal processing. Other features include a switch-mode universal power supply, useful function indicators, pro portional-speed fan-assisted cooling, removable Phoenix-style inputs, barrier strip outputs for low-Z or 70V/140V loads, short-circuit protection and more.

The XLI Series of power amplifiers from Crown® represents a new era in affordable quality power amplification. All four models in the series are powerful rugged and reliable. They are suited for musicians DJs and entertainers as well as houses of worship discos and pubs. The four models in the series are the XLi800 XLi1500 XLi2500 and XLi3500. They are identical except for output power. Features include RCA and XLR inputs user selectable input sensitivity of 0.755V or 1.4V Speakon® and binding post outputs stereo/parallel/bridge-mono mode power/fault/signal presence/clip indicators forced-air cooling; and protection against shorts no-load on/off thumps and radio-frequency interference. With over six decades of experience designing and building rock-solid products Crown is the standard in amplifier technology.Features2 Channel x 300W Stereo/Parallel/Bridge-Mono ModeUser-Selectable Input SensitivityEfficient Forced-Air CoolingRCA & XLR Inputs; Speakon® & Binding Post OutputsProtection Against Shorts No-Load On/Off ThumpsWhat's in the BoxXLI 800 2 x 300W Power AmplifierPower CableManualSpecificationsChannels: 24Ω Dual: 300W8Ω Dual: 200W8Ω Bridged: 600WVoltage Gain: 29 dBFrequency Response: 20 Hz–20 kHz +0/-1 dBTHD: 10 V/µsDamping Factor: >200Signal-to-Noise Ratio: >100 dB A-weightedCrosstalk: -75 dB at 1 kHz; -59 dB at 20 kHzInput Sensitivity: 0.775V or 1.4VInput Impedance: 20 kΩ balanced; 10 kΩ unbalancedDimensions (W x H x D): 19" × 3.5" × 12.4"Weight: 25.1 lbs.
