CROWN XTi1002 最新升级版DSP数字音频功率放大器

Crown Audio最新推出的XTi2系列功率放大器为便携式扩声带来了新定义！
Crown XTi2系列功率放大器专为便携式扩声应用而设计，产品强化了设计，改进了功能，可以处理整套扬声器系统，无需使用外置分频器、限制器和EQ，既节省空间又节约了投入。
Crown XTi2采用了Crown极具创意的PeakX Plus* 限制器。该限制器采用与I-Tech HD相同的框架结构，允许用户控制阈值、启动时间和释放时间。此外，其经过改善的次谐波合成器可以提供更准确的控制，并可以针对具体的系统或房间设置进行调整。
Crown XTi2还完全兼容HiQnet* Band Manager* 软件，该应用程序提供经过重新设计的时尚功能驱动界面，简化了系统设置和管理，确保音频专业人士、音乐家和工程师能够准确配置，精准控制。
Crown XTi2 还增加了大量预置，用户可以保存并回顾第20个到第30个预置。同时改进了电源管理，放大器上的新状态区可以监测电源温度和交流电压，可以通过高级热控制功能调节风机性能，更容易处理出现的故障。
Crown 在便携式扩声市场上一直享有盛名，提供了众多一流性价比的功率放大器。最新XTi2不仅提高了行业门槛，而且重新定义了功能，包括用户期盼已久的功能都配置在了这一系列便携式扩声功率放大器上。

Crown XTi 1002 XTi 2 Series Power Amplifier
The all-new XTi 2 Series amps by Crown continue to set the standard for unmatched performance and value, delivering the goods night after night without breaking a sweat. There\'s no debate – when you choose Crown’s XTi 2 Series, you’re choosing one of the most powerful and innovative amplifiers on the market today. Crown\'s 1002 XTi 2 Series power amplifier has up to 1,400 watts power.

With such innovations as a universal tracking switch-mode power supply and a fully integrated suite of speaker processing tools, these amps are at the top of their class when it comes to thermal efficiency and system flexibility. You also have greatly improved control capabilities. The addition of Peakx Plus* Limiters gives you full command over threshold, attack and release, and we enhanced the Subharmonic Synth so you can easily manage frequency, gain and filter type, allowing for application-specific tuning.

Plus, you\'ll now be able to tailor fan speed for specific applications and have software visibility of the power supply temperature and AC line voltage. Combine all of that with integrated cast-aluminum rack handles for maximum durability and portability and you have the power to move you – and the world.

Integrated Processing

Input EQ: 6 parametric filters per channel with adjustable Q, ±15 dB boost/cut. Also adjustable high and low shelving filters. This 8-filter EQ section can be bypassed
Crossover filters: Highpass and Lowpass per channel. Butterworth 6/12/18/24 dB per octave. Linkwitz-Riley 24/48 dB per Octave. Also includes ± 15 dB bandpass gain and polarity control
Output EQ: 8 parametric filters per channel with adjustable Q, ±15 dB boost/cut. This 8-filter EQ section can be bypassed
Delay: For signal alignment of driver; 50 mS of total delay
SubHarmonic synth: Takes the low-frequency content of the input signal and "synthesizes" a new signal that is the same as the input signal but one octave lower. The new synthesized signal is then mixed with the original signal to create the effect. New: Users now have control over frequency, gain, and filter type
Peakx* plus limiter: User defeatable limiter that allows users to control Threshold, Attack, and Release times
Presets: 30 total presets, 29 of which are user-definable
 
Controls

Level: Two front-panel rotary level controls, one for each channel
Power switch: On/Off switch applies AC power to the amplifier
Sel/Prev/Next Buttons: Three buttons near the LCD screen that are used to access menu items and front panel lockout
LCD Screen: Backlit liquid crystal display that shows preset and processing status

Input/Output Connectors

Input connectors: XLR, one per channel
Link/Out connector: Loop-thru signal from input connector for linking another amplifier, one per channel
Output connectors: Two Neutrik* Speakon* NL4MP output connectors, Channel-1 Speakon* is wired with Ch. 1 and Ch. 2 outputs for use with optional single 4-conductor cable, Two binding post outputs (in parallel with Speakon* connectors)
HiQnet* USB connector: Type B, connects to HiQnet* network
