随着TD-SCDMA网络的不断发展,由于频率较高无线信号传输损耗大,穿透能力差,因此造成了该系统在许多建筑物室内信号覆盖不均,无法全面满足用户使用需求。
为解决该系统在建筑物室内的信号覆盖问题,在TD-SCDMA系统必然中引入了室内信号覆盖系统,该系统通过基站+有源设备(TD-SCDMA干线放大器)+无源天馈系统方式完成室内信号覆盖。
为此我公司自主研发了TD-SCDMA干线放大器,该设备可配合各类基站使用,并通过无源天馈系统,扩大基站的信号覆盖范围,使TD-SCDMA信号达到良好的均匀覆盖。
二、 TD-SCDMA干放原理框图三、 TD-SCDMA干线放大器原理干线放大器内部由功率放大器(Tx AMP)和带通滤波器(BPF)组成下行信号功率放大模块,由低噪声放大器(LNA)组成上行小信号放大模块。
同时采用包络检波同步技术,设计出TD-SCDMA TDD时序控制电路模块,从而实现了对TD-SCDMA控制及业务信道进行有效的控制。
通过监控控制板和数据接口对干线放大器进行监控的数据采集和数据控制。

The Company has designed and manufactured products for world-class artists, and their legendary DN780 reverb processor is considered by leading audio engineers around the world as the industry standard. Check out their website to learn more about KLARK TEKNIK 's legendary heritage.TURBOSOUND is proud to incorporate custom-engineered KLARK TEKNIK DSP into their products. From the instant your signal enters the MILAN M10, the built-in DSP (Digital Signal Processor) takes over, ensuring the highest possible signal integrity. Much more than just selective EQ enhancement, the M10’s 24-bit DSP analyses the incoming signal and intelligently applies specific filters to actually improve the sound quality. It is very much like having an audio engineer monitoring the input and output signals of each M10, dialing in the perfect EQ and constantly making subtle adjustments to the crossover, compressor/limiter and more – which all adds up to significantly better sound.600-Watt Output PowerWith its 600 Watts of pristine digital output delivered through separately-powered drivers, courtesy of true bi-amping (two amplifiers per speaker system), the M10 delivers high-resolution sound that brings out the best in your music. While some of our competitors apply simple passive crossovers, which inaccurately separate the frequency spectrum and degrade driver performance, TURBOSOUND has gone the extra distance – driving each woofer and tweeter with a separate amplifier for impeccable signal integrity.Class-D - Massive Power, Perfect SoundThanks to our revolutionary Class-D amplifier technology, we are able to provide enormous power and incredible sonic performance in an easy-to-use, ultra-portable and lightweight package. Class-D amplification makes all the difference, offering the ultimate in energy efficiency and eliminating the need for heavy power supplies and massive heat sinks. This amazing technology makes it possible to design and build extremely powerful products that are significantly lighter in weight than their traditional counterparts, while using less energy and protecting the environment. The lightweight Switch Mode Power Supply, coupled with the industry-leading K LARK TEK NIK Digital Signal Processing (DSP) module, provides dynamic equalisation and sophisticated limiting functions, ensuring optimal performance and long-term reliability.Integrated MixerThe onboard mixer features a Level control for each input and a two-band master EQ, complete with a switchable Low Cut filter (set at 100 Hz), which allows the M10 to provide superb clarity and projection when used as a wedge monitor – or to ensure correct integration with subwoofers. An additional filter allows the user to select Speech (for enhanced voice intelligibility), or Music for the broader frequency range required for the high-fidelity reproduction of musical content. A convenient Mix Out XLR connector sends a post-EQ mix of both input channels to additional powered loudspeakers – for fast and easy system expansion.Custom-Engineered DriversPowerful, high-efficiency Class-D amplifiers and Switch Mode Power Supply technology coupled with state-of-the-art DSP functionality sounds very impressive – but what about the part of the system you actually hear? We are known internationally for making some of the best-sounding speaker systems in the world, so we take our drivers (woofers and tweeters) very seriously. Our LF and HF drivers are designed specifically for each application – it is what sets us apart from the competition. When you buy a MILAN M10 loudspeaker, you can rest assured the high-excursion 10" LF and 1" high-temperature dome compression drivers inside have been engineered to perform flawlesslyin conjunction with every other element for truly professional results.Wide DispersionThe M10’s HF compression driver is mated to a specially designed converging elliptical waveguide, which provides a smooth and pristine midrange to high frequency transition – while maintaining wide dispersion and exceptional pattern control.600 Watt 2 Way 10" Full RangePowered Loudspeaker with KLARK TEKNIK DSP Technology for Portable PA and Installation ApplicationsM10Rock-Solid PerformanceDesigned to provide exceptional performance for traveling musicians, houses of worship, banquet facilities, night clubs – and a host of other venues, the 600-Watt MILAN M10 puts touring-grade sound quality into a scalable loudspeaker system that is supremely portable and versatile. See your authorised dealer, or place your M10 order online today – and let your audience experience the TURBOSOUNDdifference!Built for Durability and VersatilityThe M10’s trapezoidal enclosure is fabricated from high-density polypropylene, and ribbed extensively externally and internally to eliminate resonances – and to provide an attractive, durable cabinet finish. The symmetrical 43° side angles allow the loudspeaker to be conveniently used as a floor monitor. A recessed carry handle on the top is provided for easy lifting and transport, while the dual-angle, pole-mount socket allows the loudspeaker to be mounted on straight poles or speaker stands, either vertically or raised higher and angled down to optimise audience coverage. A total of six M10 rigging points are provided on the top and bottom of the cabinet for secure vertical or horizontal suspension in permanent installations using M10 shoulder eyebolts. Mains power is connected via a non-locking IEC with integrated fuse holder. The illuminated front badge operates in one of three modes: permanently on; permanently off; or to indicate limiting.You Are CoveredWe always strive to provide the best possible Customer Experience.

Theater 7 Power AmplifierSETUP GUIDEGetting StartedKrell’s history is rich with breakthrough Class A amplifiers that have helped build the Krell legacy of offering the best sounding amplifiers available. Audiophiles have always considered Class A technology to be the best sounding operating state for amplifiers. However, despite Class A’s unrivaled sound quality, it has fallen out of fashion because of recent demands to reduce power consumption and heat in home electronics products. Krell engineering took this challenge and redefined the meaning of high performance power amplifier. Our goal – unmatched performance, elegant design, and a compelling array of features. The breakthrough, iBias, a patent pending circuit delivering Class A operation without the excessive heat and wasted energy of conventional designs, housed in a striking new form factor, with network connectivity for advanced access and monitoring. The sound is open and unconstrained, in a manner that rivals live performance and the true sound of voices and instruments. Music and dialogue are reproduced with a richness, detail, and startling dynamics that fill a room.The Theater 7 amplifier is easy to operate and integrate into your system.Do not place the amplifier where it could be exposed to dripping or splashing.Do not remove or bypass the ground pin on the end of the AC cord. This may cause radio frequency interference (RFI) to be introduced into your playback system.The ventilation slots on the top and bottom of the amplifier as well as the fan openings on thebottom must be unobstructed at all times during operation. Do not place flammable material on top of or beneath the component.Turn off all systems’ power before connecting the amplifier to any component.Make sure all cable terminations are of the highest quality, free from frayed ends, short circuits, or cold solder joints.THERE ARE NO USER-SERVICEABLE PARTS INSIDE ANY KRELL PRODUCT .1.Open the shipping box and remove the top layer of foam. You will see these items:2.Carefully remove all items from the shipping box.3.Place the amplifier in a safe location and remove the protective plastic wrapping.WARNINGS Krell Theater 7 Amplifier 1UnpackingKrell Industries, LLC., 45 Connair Road, Orange, CT 06477-3650 USATEL 203-799-9954, FAX 203-799-9796*****************************, WEB SITE Connecting the Theater 7 Amplifier to Your SystemBecause of its powerful amplifier channels and high-capacity power supply, theTheater 7 will benefit from a dedicated AC circuit.

2、工程安装注意事项:
A)、安装地点的勘察:大多数干线放大器用于楼层的再分布覆盖,通常是对耦合基站或无线直放站MS端口的信号进行放大达到扩大基站覆盖范围,干线放大器的重发天线应安装在基站覆盖区边界处。由于重发天线是定向角度天线,其安装点最好选在盲区边沿。尽量减少干线放大器与基站重叠覆盖的区域面积,以保证对LTE2.1G系统的干扰尽可能最小。一般在选择待覆盖点时,需要使用频谱分析仪或路测仪对基站信号强度进行监测(确保在弱信号区),避免在基站覆盖交叉区域和基站导频切换频繁地区安装干线放大器。安装地点勘察应综合考虑上述因素。
