D2Audio MXR and MXM Digital Amplifiers

 AUSTIN, Texas - Oct. 6, 2004 - D2Audio today announced two new amplifier products targeting mainstream audio systems: the MXM for multi-room distributed audio systems and the MXR for audio video receivers and home theaters. These amplifiers feature high power, superior sonic quality and performance of up to 125Watts into an 8-ohm speaker and less than 0.05% THD+N. The MXR and MXM are complete amplifier solutions that deliver market leading Signal-to-Noise Ratio (SNR) performance at greater than 105dB and with a Dynamic Range of 145 dB. Beyond achieving the robustness and sonic quality of a high quality linear amplifier, the MXR and MXM also provide the power and efficiency of a digital amplifier while offering customers a wide range of customization.

The MXR and the MXM offer a stream lined package, only 1.2 inches tall, allowing manufacturers to deliver the high power and performance into today's new thin lifestyle packages.

"D2Audio's module promises breakthrough performance in the 70-125 Watt arena," said Will Strauss, president and principal analyst of Forward Concepts. "Furthermore, D2Audio has moved beyond their original intelligent amplifiers, which actively optimize sound, to offering a higher level of truly advanced, intelligent features in a package the height and length of a video tape.

"The MXR and MXM are a continuation of D2Audio's family of intelligent digital amplifiers," said D2Audio's Chief Technology Officer, Dr. Skip Taylor. "They have the sound quality and performance level of top analog amplifiers, while offering the intelligent features and the size, weight, power and space advantages only possible in a digital amplifier. It is only through the integration of our technology that we can offer the higher power solutions at such great performance."

"These amplifiers, as with the rest of the D2Audio amplifiers, were designed to deliver amazing performance in 8-ohm designs. This design focus enables maximum flexibility for engineers. For example, the same 125Watt, 8-ohm product can provide up to 215 watts in a 6-ohm design. The customization and the robust design allow these amplifiers to be used in a variety of designs."

In addition to the market leading performance and packaging, the new MXR, MXM also deliver new advanced intelligence features:

Listening Environment Optimizer Lite (LEOL)
LEO, Listening Environment Optimizer Lite, adjusts and refines the amplifier's sound, taking into consideration the audience's location in the room, the size of the room and speakers to which it is connected. LEO also recognizes and optimizes for acoustic imperfections, such as tonal imbalances and impedance inconsistencies from different speakers and non-ideal speaker placement.

Graceful protection
Reacting similarly to a linear amplifier, Graceful Protection enables a graceful shutdown response when the amplifier is faced with inappropriate or abnormal operating power conditions. Unlike competitive solutions, which simply shut off, the D2Audio amplifier solution gracefully handles overload or exaggerated thermal conditions gracefully and without compromising the integrity of the product.

Automatic Frequency Response Correction (AFRC)
Often in digital audio systems, the sound is altered due to the complex impedances of speakers and their associated passive audio processing circuitry. AFRC lets listeners enjoy crystal clear sound by automatically correcting for the muffling of high frequencies that result from these imperfect speaker components.

Speaker Detect
Speaker Detect, one of the firmware options available with your D2Audio amplifier module, is designed to make initial set-up and configuration easier for the consumer. It eliminates the arduous user task of having to go through a set-up menu and program the receiver for each speaker present (L, C, R, Ls, Rs, Sb/Sbl, Sbr, and Sub). It automatically detects the different types of Home Theater speaker set-ups and adjusts accordingly. Speaker Detect takes a channel by channel "roll call" and recalibrates the output signals.

Speaker Equalization (SPEQ)
SPEQ further eases user set-up and additionally improves sound quality by equalizing the frequency response of the speakers and eliminating speaker resonances using an integrated full parametric equalizer. Corrected response curves for speakers can be stored within the system and can then be automatically applied to specific speakers when identified by the user.

The newly introduced MXM and MXR round out D2Audio's full line of intelligent digital amplifiers available in a variety of power levels, channel configurations and form factors.

The D2Audio Corporation, maker of the world's only custom intelligent digital amps, supplies a full line of powerful, multi-channel amplifier modules to the manufacturers of high quality audio equipment in the consumer, commercial, professional and automotive industries. Its patented intelligence technology gives D2Audio's digital amps excellent sonic qualities. All D2Audio products provide a range of customization features.
