FUNCTION DESCRIPTION
The programmable digital audio toolbox b43 is a professional
studio device for simple processing of 4 digital audio channels.
It is easy to change, to process and to rearrange up to 4 signals
with the audio toolbox b43. Level corrections for stereo or quad
mixes, channel swapping, fades - efficient and fast done with the
toolbox b43. It is not necessary to use a production mixer for
duplication, dubbing or simple editing - b43 has the functionality.
The four channel configuration matches the audio capability of
Digital VTR's. B43 can be used as remotable and programmable
audio breakout box in digital video systems.
The unit is easy to operate and requires only a limited number of
settings for fast and efficient audio production.

2. FUNCTION DESCRIPTION
All signal processing is done in the digital domain by Texas
Instruments floating point signal processors. The use of 32 bit
word length for calculation ensures that there is no deterioration
in signal quality, even if an audio signal with a maximum word
length of 24 bit is input into the processing of the unit.
GAIN means linear amplification of input or output signals. The
input or output gain can be changed in steps of 0.1 dB , within a
range from -15...+15 dB.
Adjustment of GAIN is channel independent.
Setting the matrix means to set or to reset the crosspoints of the
4x4 mix-matrix. Because this matrix is a mix-matrix each output
line can be the sum of up to all four input lines. Amplifying and
mixing the input signals can make OVERLOAD! If an Overload
appears, the output level display shows the corresponding
„OVER“-message.
A fade is started automatically every time, if a matrix point is
modified. This fade is a linear change of input gain from current
value to infinity (or the other way) at a specific time (FADE
TIME).
fader function each recall of preset is starting fade in or fade
out depending on matrix setting
set of matrix point > fade in
reset of matrix point > fade out,
If at an output line the input crosspoints of different channels
become set and reset at the same time a linear crossfade is
made between these input signals.
FADE TIME adjustable fade time (0 .. 5 sec)
For each input channel there is an audio delay available. The
delay is adlustable between 0 and 160 ms in steps of 1 ms.
The delay can be used to give a correction if the audio signals
are in the right timing.
In case that the input signal (audio pair 1/2 or/and 3/4) is not
audio (but AC-3, Dolby E, MPEG..) the input can be feeded
directly to the related output bit transparent (no bit changes). The
unit is switching to transparent automatically if “non audio” flag
in the Channel Status Bit of the AES signal is set. Otherwise
transparent mode can be set manually by the user.

LEVEL DISPLAY
There are two level displays available - input level and output
level display (For all four channels). The audio level is
displayed as bargraph. This display is not scaled. Two
segments are appr. 2dB of audio level. The level display gives
information about the existence and the size of the audio
signals.

REMOTE SYSTEM
i 3: IIII i 4: IIIIIIIIII
Only the output level display can show an overload. If an
overload appears, the output level display shows the
corresponding „OVER“-message.
The digital audio toolbox b43 is fitted with an serial remote
interface in RS-422 format.
Every device needs a device address to be registered in a
remote system. The address can be selected with the ADDR
switch on the rear panel. 16 addresses are selectable (0..F).
The changed address is valid with next power-on reset.
Up to 16 toolboxes b43 can be controlled from one remote panel.
Device model name and device address are to recognize using
the remote protocol of serial remote interface by an automation
system or by PC. With it various boxes can be combined in one
remote system or remote chain. However a maximum of 16
devices per model can be controlled in one chain.

SYNCHRONIZATION
OF
DIGITAL OUTPUT
The digital audio toolbox b43 has a digital signal output only. To
the problem-free combination of following digital devices, the
digital signal processing can be locked to an external clock
reference. The selection of the corresponding input is made in
the SYNC MODE menu. If the chosen sync input is connected
with the sync signal, this signal is used for synchronization
automatically. The digital output signal can be clocked with the
following clock frequencies:
CH 1/2 locks with the clock frequency of the input signal at
digital input CH 1/2 (AES/EBU, 48 kHz)
EXT SYNC locks with the clock frequency at the
external sync input (AES/EBU, 48 kHz)
VIDEO locks with the clock at the Video sync input
(internal 48 kHz)
SDI VIDEO locks with the clock at the SDI input
(internal 48 kHz)
Both digital outputs CH 1/2 and CH 3/4 are locked with same
clock frequency.
Note: SDI sync is available only if SDI interface is installed!

The 4-channel processors of b40 series fitted with SDI-interface are
compatibel with the standard SMPTE 272M-AB. They support 48 kHz
synchronous audio sampling with 20 bit word length.
The standard allows up to four groups each of four mono audio channels.
(Usually used by most of D-VTR's and other equipment is Group 1 with 48
kHz synchronous sampling.)
Group selection and other settings are made by the front panel switches.
Therefore no switches on the SDI board has to be used.

RECALL OF
PRESETS
The digital audio toolbox b43 is a programmable mix matrix.
The device is operated by recalling presets. It has four preset
buttons with which the appropriate preset is called on in each
case. In a preset, matrix configuration and all parameters which
can be adjusted at the device are contained. Therefore, one will
normally define four matrix configurations, to store them as
presets. The desired channel configuration can then be
activated fast and simply by calling the corresponding preset (at
the device or by external control).

INITIALIZATION
THE UNIT
Should have remained the device no more operable and/or in the
program execution stand, recommends itself an initialization the
device.
During initialization, all storage areas important for the program
and registers are loaded with the factory setup and the program
is restarted.
Any button is to be held pressed in order to initialize the device
during switch-on of the device until the program started. To the
start of the program and at the completion of the displays (how
described in 7.1), the device is ready for operation with the
factory setup.
After an initialization of the device, all user presets and
adjustments are erased and/or overwritten by the factory
setup!

8. APPLICATION NOTES
APPLICATION NOTES
In digital video recording technology four digital audio channels
are the standard configuration. This channel capacity is used
increasingly in production and post-production for surround
sound, providing mix options and for multi-lingual productions.
Quite often it is necessary to make corrections or changes to the
audio which until now required the use of an expensive digital
audio mixer. These tasks can now be easily solved with the
Jünger Audio range of digital audio toolboxes. Simple
processing for up to four digital audio signals may be carried out
quickly and efficiently.
Using the SDI versions (SDI=Serial Digital Interface, digital
component video format with 270Mb/s transmission) b40 series
can process embedded audio.
The standard allows up to four groups each of four mono audio
channels. Usually used by most of D-VTR's and other equipment
is Group 1 with 48 kHz synchronous sampling. Synchronous
means that the audio clock is genlocked to the associated video.
Each channel can have up to 20 bits of resolution per audio
sample.
The 4-channel processors of b40 series fitted with SDI-interface
are compatibel with the standard SMPTE 272M-AB. They
support 48 kHz synchronous audio sampling with 20 bit word
length.
The Jünger Audio SDI interface provides for one group of four
audio channels to be extracted from or inserted into the SDI data
stream. To address a specific channel group the group selection
is possible (see 4).
The b40 provides an optional SD- or HD-SDI board. When you
switch on the device the plugged in interface will be indicated in
the display
FEATURES
• Bypass relay for SDI IN >SDI OUT
• Bit transparent for coded data streams (e.g. DOLBYE/20bit)
• De-embedder: user selectable de-embedding of one group
• Embedder: user selectable embedding to one of 4 groups
• SDI-SYNC: SDI input can be the clock source of the device

BASIC WORKING
MODES WITH SDI
• For HD-SDI: Multi-Format HD/SD operation with auto detection
For the basic working mode the input of the digital audio
processing can be selected between AES/EBU or SDI (serial
digital video with embedded audio). The processed signals are
present at both outputs always - at AES/EBU and SDI.
There are two additionaly working modes using the SDI interface.
SDI Bypass is bypassing the SDI data stream. In this case only
extracted audio is processed and available at AES output. In Split
Mode the audio path is splitted. Embedded audio can be
processed with external equipment via AES interface.
Following illustration shows working modes:
