全铝机箱密封无风扇设计K2，功率大

本帖最后由 windowsxpofms 于 2012-4-5 00:23 编辑 全铝机箱密封无风扇设计K2，功率大。工作正常，机面有刮痕看图片。 K2 Amplifiers deliver more power and sound while using less energy than conventional amplifiers. And its all in a durable, maintenance-free package thats just two rack spaces high. Using patented Balanced Current Amplifier (BCA) circuitry, K Series amplifiers give you massive amounts of power while generating just one-tenth the heat of conventional amplifiers. In fact, the powerful K2 amplifier can deliver an amazing 1,250 watts per channel into 2 ohms (and that's a very solid 2 ohms)! Because of their incredible efficiency, K Series amplifiers require no internal cooling fan and feature a closed chassis. Of course, no fan means no fan noise. In addition, the closed chassis makes these amplifiers virtually immune to environmental problems such as dust, cigarette smoke, stage fog and spilled liquids. Features： 2 x 1250 瓦  2 Ohm 2 x 800 瓦  4 Ohm 2 x 500 瓦  8 Ohm 桥接 2500 瓦  4 Ohm 桥接 1600 瓦 8 Ohm No Fan / No Noise 2,500 Watts, 2 ohms K2 Patented BCATM Circuit Design Unmatched Thermal Efficiency Superior Energy Efficiency Sealed Chassis Universal Power Supply Superior Sound Accurate, uncolored sound with very low distortion for the best in music and voice reproduction High damping factor for tight, clean bass response Advanced design for energy conservation Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheating,high-frequency overloads and internal faults Extremely versatile, handling a wide range of speaker impedances and outputs Output Power: See power charts below. Voltage Gain: K1: 31.55 dB gain at 1.4 volt sensitivity; 26 dB gain at 2.65 volt sensitivity. K2: 32.88 dB gain at 1.4 volt sensitivity; 25 dB gain at 3.0 volt sensitivity. Line Voltage Requirements: Universal power supply can be configured to operate with 100,120, 200, 220, 230, 240, 250VAC at 50 or 60 Hz. Adapters are acquired through an Authorized Service Center. Signal to Noise (A-weighted): > 100 dB below rated power. Damping Factor: > 3,000 from 10 to 400 Hz

这个和K2相比有啥区别了，音色，推动力等？

后级功放主要是推力和收得住。音色更多取决于前级。都是同一品牌，差别不大。
说后级音色多么好，有点不厚道。

已经回答同样的问题。
这台功率大一些，没有风扇，都是全铝壳机器散热。
当时这两台功放都是为录音室设计的。这台有专利。
