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

INSTALLATION
The digital filter processor e07 was carefully packed in the
factory and the packaging was designed to protect the
equipment from rough handling. Please examine carefully the
packaging and its contents for any signs of physical damage,
which may have occured in transit.
The digital filter processor e07 is manufactured under the safety
category Schutzklasse 1 in keeping with the VDE 0804
standards.
Check the voltage details printed at the rear panel are the same
as your local mains electricity supply.
The digital filter processor e07 is equipped with standard
connectors (see chapter 3).
Before connecting the digital filter processor e07 switch the
power off at all connected units.
The digital filter processor e07 is made as standard 19“ unit (EIA
format). It occupies 1 RU (44 mm height) space in a rack.
Please allow at least addititonal 3“ depth for the connectors on
the rear panel.
When installing the unit in a 19“ rack the rear side of the unit
needs some support, especially for mounting in flight cases.
The filter processor should not be installed near units which
produce strong magnetic fields or extreme heat. Do not install
the filter processor directly above or below power amplifiers.
If, during operation, the sound is interrupted or displays no
longer illuminate, or if abnormal odor or smoke is detected
immediately disconnect the power cord plug and contact your
dealer or Jünger Audio.

The filter processor e07 offers a convenient preset storage
system for saving and loading of parameters. Following
parameters are stored in presets:
equaliser bands (also dynamic equaliser)
2-channel mode equaliser bands
low cut / high cut filter
output gain (also for 2-channel mode)
bypass functions (also for 2-channel mode).
Until 50 presets can be stored into the unit. In 2-channel mode
both parameter sets for left and for right channel are stored in
one preset.
Presets can be named by the user.
Presets can be used for A/B comparison and for snapshot
automation.

Until 50 snapshots can be stored into the edit list (EDL).
EDL can only used in the channel status of first generated
entry (stereo or 2-channel mode). In case of working in
another mode as the original EDL mode only the CLEAR
function is available. After clearing the EDL one can
generate a new EDL.
In 2-channel mode both parameter sets for left and for right
channel are stored as one snapshot.
Without timecode the snapshot edit list (EDL) can be used as
event list. Events are arranged by time code values.
