ICEpower (Denmark) was founded in 1999 as a joint venture with Bang & Olufsen, a well-known manufacturer of audio and video equipment, and today the ICEpower brand is well known throughout the world, including Russia.
ICEpower is a fast-growing company that is a leader in the development of advanced Class D audio amplifiers. High performance, high transmission density of acoustic energy and high energy efficiency are the three components of ICEpower's market success.
The basis of ICEpower amplifiers is the analog-digital core of its own design, made in the form factor of a separate chip. The company has dozens of patents for original solutions in the field of audio processing. ICEpower products have proven themselves in many projects. Customers and partners of ICEpower are such well-known companies as Bang & Olufsen, Asus, Bowers & Wilkins, Pioneer, Alpine, Samsung, Audi and others.
Technology
icepower is distinguished by its innovative approach to the development of class d amplifiers. its amplifiers process analogue signal, hence the name of icepower technology - "analogue class d" (analogue class d) or "analogue switching". unlike the usual technique of obtaining signal shims with the help of a triangle pulse generator, icepower technology uses an auto generator covered with multiple feedback, which ensures consistently high quality of audio regardless of the load. icepower's key technologies are called icepower.
In most cases, ICEpower amplifiers are integrated with the high quality AC/DC switching power supply of the ZVS/ZCS proprietary design, thus eliminating a number of problems for audio system designers in selecting or developing a power subsystem.
Products
ICEpower manufactures complete modules of high power, high quality sound amplifiers in a PCB form factor, including a specialized processor in the form of an ICEpower integrated circuit, power keys, capacitors, filters and other discrete components, as well as a network power supply. The company manufactures amplifiers with a variety of channels and a wide range of output power.
ICEpower amplifiers are characterized by exceptional sound quality and fidelity, high power density and efficiency, as well as small size and mass, which determine their widespread use in professional sound and in the consumer Hi-Fi segment. The range of amplifiers produced allows the developer or system integrator to quickly obtain a final solution with the required number of amplification channels and the required output power, with bridge or half bridge output stage configuration.
The ICEpower family of amplifiers is optimized for a specific range of end products. The A and ASP Series will be an excellent choice for building powerful amplifiers or active loudspeakers for concert halls. The ASX2 Series is optimized for stereo amplifiers in the consumer segment of Hi-Fi audio equipment. The 150ASH7 and ICEmatch Series amplifiers are perfect for home theatre and other multi-channel solutions.
series A and ASP
High reliability of operation and excellent resistance to mechanical and vibration effects, combined with high output power, favorably distinguish this family in the market of professional audio products, including for the automotive segment.
The A Series includes 250W, 500W and 1000W amplifiers that require ±12V power as well as an output stage power supply. Logic mute (MUTE) and standby (STANDBY) inputs are provided on the boards, as well as a monitor output to monitor the output signal. The amplifiers have a balanced input optimized for the differential signal.
The ASP Series is a 250W, 500W and 1000W amplifier with an integrated 110/220V mains power supply that can supply additional amplification channels built into the A-series or AC-series modules. The channels of the ASP Series are virtually identical to those of the corresponding power amplifiers. Each ASP module also provides ±12V power.
The combination of the A and ASP Series provides a flexible, modular approach to end product development, making it easy to design a whole line of end products, from a conventional subwoofer amplifier to a three-channel active speaker system. The main applications of the A/ASC Series are studio and concert hall active speakers, active subwoofers, high power stereo amplifiers.
series ASC
The 200ASC, 200AS and 200SC modules represent a budget line of ICEpower amplifiers with balanced power and sound quality characteristics designed for use in subwoofers, external amplifiers for electro-music instruments (combos), wide range active loudspeakers, as well as room and hall sound systems. The ASC family of amplifiers has a relatively low cost, which makes them attractive for the construction of high quality end audio systems. The ASC series is optimized for
The 200ASC module contains a 200W amplifier and a 310W switching power supply unit. In addition to the 47V main power output for the amplifier, the power supply unit provides an additional output voltage of ±12V and has an output for connecting additional amplifier channels.
200AC is a separate 200W amplifier board, the same as the 200ASC module, designed specifically for use as an additional board when working with the 200ASC, 250ASP and 500ASP modules. The sound input is differential, similar to Series A, with a supply voltage range of 22 ... 50 V.
200SC is a separate power supply unit for the 200ASC module. Separate power and amplification units provide the developer with additional possibilities for optimizing the device when there are spatial constraints in the final system layout.
series ASX2
The ASX2 series includes amplifiers with two half-bridge channels and an integrated network power supply. Two half-bridge outputs can be configured into a single bridge output. The exception is the 50ASX2 amplifier, which is available in two versions: 50ASX2SE half-bridge and 50ASX2BTL bridge.
The input of this series of amplifiers is unipolar, and when activated in bridge mode, it becomes balanced. All models have a logic input to cut off the amplifier, as well as logic outputs of the monitors of overheating and overcurrent. In addition, there are outputs of unstabilized voltage ±24 V with a load capacity of approximately 200 mA, sufficient to build a preamplifier or DAC.
An interesting feature of ASX2 amplifiers is the ability to redistribute power between the channels by switching on asymmetric load. When switching on a symmetrical load, its minimum resistance should be at least 3 ohms, however, if one of the channels has a load resistance of at least 6 ohms, then the other channel can switch on the load of 2 ohms...
The ASX2 series amplifiers deliver sound quality worthy of the attention of true audiophiles and cover the output power range of 25 to 630 W. The power density for this family of amplifiers reaches values above 1 W/cm.3ASX2 modules will be an excellent choice when building a high quality stereo amplifier, active acoustics, studio monitor.
series ICEmatch
icematch series consists of 400sm mains power supply 400w and dual-channel 80am2 amplifier. one 400sm module can support up to eight 80am2 modules, thus providing a wide range of options for building a variety of end devices from high quality stereo amplifier to multi-channel studio monitor. 400sm supports the main power bus and channels of auxiliary output voltages +5v, ±12v. In addition, it has a number of additional pins to control the power supply mode and display its composition.
80AM2 is a complete compact amplifier with an output power of 2 ' 80 W in a half-bridge switching on load 4 Ohm and up to 160 W in a bridge switching on load 8 Ohm. The amplifier has a balanced input, power supply to the power stage up to ±36 V.
The ICEmatch series provides the user with advanced control and monitoring capabilities. 400SM has two additional buses, one designed for 80AM2 and the other for monitoring preamplifiers.
The scope of the ICEmatch series is multi-channel amplifiers, including home theaters, active loudspeakers, studio monitors.
