Nowadays, most of the audio industries work on digital media. From recording to
playback, the complete chain relies on digital coding and storage.
Therefore, it seems obvious to stay in the digital domain as long as possible so
as to avoid the inherent losses of analogue processing.
The semiconductor industry has now acquired the expected maturity regarding the DAC
and ADC solutions. DSPs are becoming more and more powerful,making very clean audio
The time when digital audio was considered as being inferior to pure analogue restitution
Because of these reasons, ATD2 primarily decided to focus on digital active monitors.
We have paida lot of attention to the analogue audio circuitry and have first designed
state of the art DACs and ADCs. Once only we got the perfect results (both performances
and listening tests), we then inserted a DSP in the system. Our designs can in no
way be compared to those various DSP boards in which a powerful DSP is hooked to
a poor audio codec.
The digital processing is for sure the most powerful feature to guarantee a perfect
time alignment of the drivers. All of our speakers have an optimal impulse response.
An other additional advantage is the easy set-up of a multi-channel system: even
when the ideal speaker positions cannot be achieved, the time delays can be precisely
tuned in order to get a perfect time alignment of all the speakers in the surround
The speaker itself makes room equalization now possible. The embedded DSP can compensate
for variations in the room frequency response, making it as flat as possible. This
allows the sound engineer to keep its sound reference whatever room he is working
Nowadays, our digital technology allows any user to create a powerful network that
can control the entire settings available on the monitors. Moreover a smart software
design of the remote and the computer controls improves highly the ergonomics.
