DME Advantage<br />

The true power of the DME<br />

Series is witnessed when<br />

freely configuring systems<br />

from a myriad of<br />

audio-processing<br />

components. Operating as a<br />

fully-customizable DSP box,<br />

either the DME64N or<br />

DME24N can create<br />

systems satisfying a wide<br />

variety of needs. Even<br />

7.1-channel Dolby Digital<br />

EX can be easily supported<br />

by simply adding<br />

components.<br />

With digital broadcasting becoming more and more popular, ever-increasing use of surround sound formats is<br />

inevitable. What's more, continued growth of the use of DVDs, multichannel audio sources, and other products<br />

using these formats is also beyond doubt. It is no wonder then that systems capable of producing multichannel<br />

music are in extremely high demand. And while the high price of convention systems has been a constant<br />

obstacle, a remarkably flexible and reliable solution is now available in the DME64N and DME24N. Allowing an<br />

impressive array of audio processing components to be intuitively assembled in a user-friendly software environment,<br />

each of these mixing engines can be used to create indispensable tools for surround-sound music production.<br />

In addition, this impressive arsenal of mixing and processing functions has been neatly packaged into a<br />

compact hardware device taking up very little rack space.<br />

Downmixing<br />

The ability to freely configure a diverse range of<br />

audio-processing components offered by the DME Series is of<br />

immeasurable benefit when downmixing multiple audio<br />

channels for stereo playback. Even when time and budget are<br />

limited, a host of different mixes can be easily created,<br />

compared, and evaluated while still in the studio.<br />

Bass Management<br />

With the DME Series, bass management can be effortlessly<br />

achieved by combining a matrix mixer component with<br />

high-pass and low-pass filters. No additional hardware is<br />

needed. Moreover, groups of assembled components can be<br />

saved and recalled as component blocks, making it easy to<br />

monitor how mixes will sound on a variety of different<br />

bass-managed systems and to also compensate for poor<br />

low-end characteristics in mixing environments such as<br />

outside broadcasting vans and smaller studios.<br />

Monitor Speaker Alignment<br />

By providing each speaker with independent, finely-tuned<br />

delays and EQ, highly accurate monitoring environments can<br />

be conveniently setup, even when the speakers themselves<br />

cannot be ideally positioned.<br />
