INTRODUCTION

The digital filter processor 

e07

 is a high quality studio device for

audio production and mastering. It brings the sound of the best
analogue filters into the digital world.
The primary feature of this new unit lies in it's ability to process
audio in the digital domain using digital filters operating at
higher sample rates. Increasing the sample rate to 88.2 or 96
kHz, the "High Sampling Mode" does not limit the magnitude and
phase response of the filtering process to 22 or 24 kHz as most
digital filters do. Doubling the sample rate increases the audio
range that can be processed. High frequencies are faithfully
reproduced in the same vibrant and natural manner as the finest
analogue filters.

The digital filter processor Model 

e07

 is a 4-band parametric

equaliser. It is possible to use each filter band as a normal
parametric or as a dynamic equaliser, ie. a digital de-esser.
An integral digital limiter prevents clipping of boosted signals.
The Model 

e07

 is a 24 bit device sampling at 96kHz and is

designed specifically for the highest quality, high resolution
recording and reproduction.

* Outstanding signal quality achieved by high sampling 
processing

* Conventional operation from the front panel with rotary 
knobs for direct control of all parameters

* Each filter band can be used as a dynamic filter,
ie. de-esser

* Integral digital limiter prevents clipping

* Stereo or dual channel mode

* Timecode snapshot automation

* User-friendly preset and recall functions

* Ready for integration into 96 kHz systems
