Description
The ASC Series is designed for consumer and semi-professional applications, particularly in active speakers and subwoofers. Excellent sound performance and flexibility are the key distinguishing qualities of these modules. The 200ASC adds features, such as universal mains operation, an auto on/off feature, signal detection and a stand-by mode with only 0.6W power consumption. A matching 200AC amplifier, which can be powered from the 200ASC, makes building compact multi-way or multi-channel solutions easy.
Following our customers’ requests for more design flexibility, ICEpower has expanded the ASC Series with a new product, ICEpower200SC. It is the power supply part of the ICEpower200ASC module that has been separated into a new product while keeping all the unique features. ICEpower200SC can be combined with one to three ICEpower200AC amplifier modules to create audio products with unique designs and preserving excellent audio quality.
Our second reason for creating ICEpower200SC was to allow for the combinative structures of the separate power supply and amplifier channels with identical component architecture of the amplifier sections when creating 2- and 3-channel applications. This is beneficial for preserving the high standard of audio performance, characteristic of all ICEpower-driven products. ICEpower200SC provides an auxiliary +/-12V supply for external signal conditioning circuitry and the DC-bus output for powering ICEpower200AC amplifiers, which makes designing compact multi-way or multi-channel solutions easy.
Following this latest addition, the ICEpower ASC Series now consists of:
- ICEpower200ASC – an integrated audio amplification solution consisting of an ICEpower Class D audio amplifier and a switch-mode power supply on a single PCB
- ICEpower200AC - a Class D audio amplifier
- ICEpower200SC – a switch-mode power supply
ICEpower200AC is compatible with the power BUS on the ICEpower250ASP and 500ASP for applications with higher power requirements.
The ASC Series modules represent a turn-key approach to product development for assuring the shortest time-to-market for your end products.
Applications
Primary applications for ICEpower200ASC, 200SC and 200AC include:
- Subwoofers
- Active 2- and 3-way speakers
- Stereo and multi-channel amplifiers
- Multimedia and installation audio
Advantages for audio manufacturers
ICEpower ASC Series products provide a number of advantages to audio manufacturers:
- High efficiency, based on ICEpower’s proprietary technologies in switching audio power conversion.
- Design freedom for audio manufacturers in making their products in most unique and aesthetical ways. The power supply and the amplifier sections can be mounted at different angles and positions.
- The power supply with separate AUX output voltages and standby functionality makes for a compact, turnkey power solution.
- High quality and reliability of the products – the hallmarks of all ICEpower products
- Ease of integration into customer’s products
