CROWN XTi4002 最新升級版DSP數字音頻功率放大器
 
Crown Audio最新推出的XTi2系列功率放大器為便攜式擴聲帶來了新定義！
Crown XTi2系列功率放大器專為便攜式擴聲應用而設計，產品強化了設計，改進了功能，可以處理整套揚聲器系統，無需使用外置分頻器、限制器和EQ，既節省空間又節約了投入。
Crown XTi2采用了Crown極具創意的PeakX Plus* 限制器。該限制器采用與I-Tech HD相同的框架結構，允許用戶控制閾值、啟動時間和釋放時間。此外，其經過改善的次諧波合成器可以提供更準確的控制，并可以針對具體的系統或房間設置進行調整。
Crown XTi2還完全兼容HiQnet* Band Manager* 軟件，該應用程序提供經過重新設計的時尚功能驅動界面，簡化了系統設置和管理，確保音頻專業人士、音樂家和工程師能夠準確配置，精準控制。
Crown XTi2 還增加了大量預置，用戶可以保存并回顧第20個到第30個預置。同時改進了電源管理，放大器上的新狀態區可以監測電源溫度和交流電壓，可以通過高級熱控制功能調節風機性能，更容易處理出現的故障。
Crown 在便攜式擴聲市場上一直享有盛名，提供了眾多一流性價比的功率放大器。最新XTi2不僅提高了行業門檻，而且重新定義了功能，包括用戶期盼已久的功能都配置在了這一系列便攜式擴聲功率放大器上。
Crown XTi 4002 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 4002 XTi 2 Series power amplifier has up to 3,200 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
Construction
Chassis: Steel
Front panel: Cast-aluminum
