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 />
