Switch Mode Power Supplies for Audio
Even the best-sounding amplifier can seem lacking without a rock-solid power supply behind it. A sturdy power supply is the basis of any quality audio system. Without sustainable power, even the best-sounding output sections can sound dull and weak.
Sustainable Power for Audio
Music is a dynamic signal, and this means the output power is usually low compared to the highest transients (typically 1/8th in uncompressed music). But since our power supplies should also be capable of powering bass guitar amps or subwoofers, they need to be able to handle much higher continuous power. Therefore, we always aim to be able to deliver half power continuously.
As a result, ICEpower’s switch mode power supplies are perfect for enabling your high-efficiency amplifier needs. Our power supplies can be combined with ICEpower’s amplifiers, such as the 300A2, 400A2, Engine400, or ICEmatch modules. Or they can be used together with an output section of your own design. The potential applications are wide and include traditional Hi-Fi amplifiers, multichannel home theater, whole home audio, commercial audio, studio monitors, subwoofers, PA speakers, sound reinforcement, and even non-audio applications.
Our power supplies include a main converter as well as an auxiliary power converter, typically both +5V for powering digital circuitry as well as +/- 12 – 15Vdc for analog circuitry.
All our power supplies are pre-approved to the latest safety and EMC standards in order to simplify your product development process, and most also comply with the ErP and Energy Star requirements for low standby power mode.
Reliability is a key focus for us. This has been achieved through careful design, the use of brand-name components, and meticulous testing and burn-in in mass production. Every single module goes through a comprehensive functional test in production before delivery to the customer. Furthermore, all our power supplies incorporate comprehensive protection features, such as thermal monitoring, over-current protection, over/under voltage protection, etc., to protect against failure in use.
