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.

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.

The digital filter processor e07 can be used in stereo or in 2channel mode. Changing of the channel mode requires rebooting of the unit. In stereo mode all parameters are the same for left and for right channel. The limiter is working in linked mode. All functions are available. In 2-channel mode all parameters can be different for each of the two channels. The limiter is working unlinked. Dynamic equaliser is not working in 2-channel mode. A/B comparison is available for two pairs of L/R parameter sets L/R parameter sets are storable in presets.

4. OPERATION

DATA SAVE is a function for saving and restoring existing preset data and editlist by using external storage devices. All data will be transferred via AES/EBU interface. It is possible to use all storage medias which can be connected via AES/EBU and which don’t change or manipulate audio data of AES/EBU signal (f.i. DAT, audio file on workstation). The data block has a duration of appr. 10 seconds. The header of data dump block is containing number and name of data block. This is to be used to address determined data block for saving or loading.

APPLICATION NOTES

Reputation has it that digital filters sound hard and metallic, that there is no warmth and clarity and the dynamic and stereo imaging is flat. Many sound engineers consider that "high quality analogue filters simply sound better". The difference between analogue and traditional digital filters is, in the final analysis, related to the frequency range of the filters. The frequency range is clearly wider in the case of analogue filters than the traditional digital filter which is sharply limited to half of the sampling rate of 40 or 50 kHz, ie. around 22kHz. As a result, non-linearities in amplitude and phase characteristics occur well before the cut-off frequency which lead to coloration at high audio frequencies.

In order to implement a digital filter whose sound qualities are comparable with a good analogue filter, the corresponding transmission characteristics must be designed in digital form. High quality digital filters should sound as good at high frequencies as good analogue filters and in order to achieve this a higher sampling frequency is required. The distortion of the frequency axis is reduced the higher the sampling rate becomes relative to the audio range.

The Jünger Audio digital filter processor Model e07 works internally at twice the sampling rate of the input signal and can therefore provide filtering up to around 40kHz moving any distortion of the signal away from the audio spectrum. This results in a much cleaner audio signal. Listening tests show remarkable results with a more realistic and "authoritative" sound. Stereo imaging is preserved and reverberation decays naturally without any "metallic" components. This situation can be proved technically by measuring the results which clearly show an improvement at higher frequencies together with improved phase characteristics.

6. APPLICATION NOTES

In dynamic mode the filter activity is controlled by the audio level. The filter get active only if the level of incoming audio signal reaches a defined threshold level. A typical application for a dynamic equaliser is the de-esser function.

There are two basic modes for the dynamic equaliser, dependent on adjusted RANGE value. Negative values for RANGE (cut function) switches into REDUCE mode. In REDUCE mode signals will be reduced if their level is higher as the threshold level. All spectral parts of the signal (filtered by the filter band) which has more level as the adjusted threshold level will be reduced by the RANGE value. The level reduction never comes below the threshold level.

Positive values for RANGE (boost function) switches into ENHANCE mode. In ENHANCE mode signals will be increased (or enhanced) if their level is below the threshold level. All spectral parts of the signal (filtered by the filter band) which has less level as the adjusted threshold level will be increased by the RANGE value. The increased level never comes over the threshold level.

Caused by the limited DSP power of the unit two bands can be switched as dynamic equaliser at the same time only. The other bands can be used as normal equaliser bands. All equaliser bands are calculated at doubled sample rate or 96 kHz. In 2-channel mode dynamic equaliser function is not available.

The Digital Filter Processor e07 is working internaly with doubled sample rate. That means that the filter calculation is proceed at doubled sample rate of the input signal (88.2 kHz for

44.1 kHz input or 96 kHz for 48 kHz input).

6. APPLICATION NOTES

The audio signal delay through the digital filter processor is approx. 2ms due to delaying of the audio signal using internal memory. A small delay is deliberately introduced to the audio signal in order to allow limiter and filter algorithms which can 'preview' the audio signal before changing it. This delay must be considered before attempting to mix signals processed by the dynamics processor with other undelayed signals.

When mixing together a delayed signal and a direct signal there may be cancellation of the signal waveform at some frequencies and re-inforcement of the waveform at other frequencies (comb filter effect). Corresponding 2ms delay of direct signals should therefore be carried out before mixing them with delayed processed signals.
