2 Introduction
Welcome to the SINTEFEX CX2000 Sampled Compressor
Welcome to the unique Sintefex technology of the CX2000 sampled stereo compressor.
This product includes the proprietary Sintefex Dynamic Convolution technology to bring the signal
processing qualities of classic analogue compressors into an all-digital world.
The CX2000 Sampled Compressor stores internally 8 compressor samples/profiles at each sampling rate
and 100 user programs.
In addition, if used under remote control, unlimited additional compressor profiles are available from the
web based library of sampled compressors.
USB remote control software for the PC is included with this product.
What is a Sampled Compressor?
Digital Signal Processing can be very clean but digital compressors do not add any of the fine texture to
the sound that classic analogue compressors have been used for and sought after for years.
One technical reason for the rather boring sound of digital compressors is that that the process carried out
by the digital signal processors is usually very simple. That's why on many computer systems you can
run multiple compressors in real time using just a small DSP farm or even the native processor of the PC.
It has to be a simple calculation to be quick and it sounds simply uninteresting.
Sintefex Audio have invented a way of sampling the signal path of classic analogue equipment and
recreating that sound digitally. It is not an approximation for analogue processing thought up by some
computer whizz-kid but uses the actual samples form the original equipment.
Sintefex Audio's unique Dynamic Convolution algorithm uses about 1000 parameters gathered from the
original device to generate a complex signal process that involves some heavy number crunching. You
will hear instantly that it adds colour to the audio signal path that you would otherwise have to get from
analogue equipment.
Of course the advantages of the digital system is that the processing can be identical in two channels of a
stereo mix, and be repeatable for any further use of the effect. Analogue gear has a habit of not working
when you need it or adding unpleasant side effects like hum and noise, and bad stereo matching gives
image shifting.
The CX2000 stores a set of 8 classic compressor samples at each sampling rate and gives you 100 user
program stores for your settings. An unlimited number of compressors can be available if the CX2000 is
linked to computer using its USB port for remote operation.
The combined cost of a stereo pair of each of the stored compressors in a standard CX2000 would not
leave much change from $50,000US!
