Mini Amplifiers Target Powered Speakers and In-Wall Audio Systems

Austin, Tex. — D2Audio Corp. is kicking off a new family of miniature digital amplifiers with the MXS series two-channel amplifiers.

These digital amplifiers can deliver up to 125 W/channel into 8Ω speakers or up to 250 W/channel into 4Ω speakers. These compact, high performance two channel amplifiers are cost effective, while featuring market leading performance in line with the rest of the D2Audio family with THD+N of less than 0.1% at full rated power from 20 Hz to 20 kHz and a dynamic range up to145 dB.

The MXS is practical for applications where space is small, but the sound should be superior, like bi-amp-powered speakers, wall plate audio controllers, plasma TVs and mini-stereos. The new mini-digital amplifier's 93% power efficiency minimizes thermal considerations and offers the customization and intelligence features expected of D2Audio products.

This miniature design (2.86 x 3.43 x 1.2 inches) is also optimized for bi-amp loudspeaker products and even subwoofers. It offers highly flexible, programmable crossovers on each channel for quick, simple yet very high quality designs; as well as unparalleled audio processing flexibility for customizing amplifier and speaker performance.

Using the D2Audio design tool, Audio Canvas, designers can drag and drop to develop their own signature sound. Unlike most digital amplifiers, the MXS' sophisticated graceful protection allows the MXS to react to abnormal situations like a linear amplifier would with smooth brownout recovery, soft-current limiting without shutdown, and automatic short circuit recovery. Additionally, the D2Audio controller IC with embedded DSP core and the non-volatile memory of the MXS enables simpler, more cost effective product designs.

Pricing for the MXS100-2 (100/W per channel, 2 channels) is $46 in quantities of 5,000.
Pricing for the MXS50-2 (50/W per channel, 2 channels) is $35 in quantities of 5,000
