2. FUNCTION DESCRIPTION
The digital audio delay b45 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 preselected address is valid with next power-on reset.
Up to 16 delays b45 can be controlled from one remote panel
brc4x.
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.

VIDEO FORMAT
The LINK function is used for channel configuration regarding
delay time adjustment. It eables convenient setting of delay time
for a group of audio channels. Following links or channel
configuration are possiblel:
CH1 + CH2 + CH3 + CH4 (all 4 channels linked)
CH1 + CH2 CH3 + CH4 (two linked pairs)
CH1 CH2 CH3 CH4 (all channel independent)
The LINK function is a basic setting and is valid for all presets.
All linked channels are working with the same delay time.
Adjustment of delay time is valid for linked channels at the same
time.
The display is showing delay time for all four presets (not more
for individual channels) if all four channels are linked (P1 ...P4).
The adjusted delay time can be displayed in various time scale
formats. The time scale format is to select in DELAY menu. The
resolution for the adjustment is changing with selection of
specific time scale format. For some formats (f.i. frames)
adjustment is possible in larger steps only.
Time scale format can be different for different presets. Time
scale format will be stored by storing adjustments into the preset.
To get the right delay time (as absolut time value) it is necessary
to set the correct video format (PAL/NTSC). The video format is
to select in setup menu.
If the unit is synchronized to video reference the selection of
video format is done automatically independent of the video
format selection in setup menu.
page 2-4 operation manual b45, chapter 2 -Function description-
2. FUNCTION DESCRIPTION
The digital audio delay b45 can be used in Auto Tracking Mode.
Auto Tracking means the control of current delay time by specific
generated control signal. Together with the „glitch free“ changing
of delay time Auto Tracking works without any noises or
detoriation in the audio signal.
The control signal for auto tracking can be generated in different
ways. Depending on the generation of the control signal it is
causing a different maximum length of auto tracking delay time.
There are two basic methods to generate the control signal. First
one is the comparison of two video signals. The video program
signal (VIDEO TRACKING) will be compared with video
reference (VIDEO SYNC). Difference in time between both
vertical intervals is used as auto tracking delay time. Second way
is to use a TTL signal. The length in time of the pulse signal is
measured and will be used as current delay time.
Selection of auto tracking mode is done by setting jumper J2 on
tracking board (see also 4.4).
The digital audio delay b45 can generate the auto tracking
control signal by comparison of two video signals. To calculate
the auto tracking delay time the algorithm compares the video
program signal (VIDEO TRACKING) with video reference
(VIDEO SYNC). The difference in time between both vertical
intervals is used as auto tracking delay time. The maximum
difference and in this way the maximum delay time is one video
frame (PAL = 40 ms).

AUTO TRACKING
WITH OFFSET
The digital audio delay b45 can generate the auto tracking
control signal by using a TTL control signal. To calculate the auto
tracking delay time the detection circuit is measuring the HIGH
period of the TTL input signal. The length in time of the HIGH
period is used as delay time for auto tracking. The maximum
delay time shouldn’t be more as the maximum memory capacity
of the delay (see technical specifications). Otherwise it produces
a memory overflow and an error message will be displayed.
Every new positive pulse at TTL input is measured and is
overwriting the last calculated value.

There is the possibility to activate auto tracking even if a fixed
delay time is preadjusted. The already adjusted delay time is an
offset to the auto tracking delay time. Please note that the overall
delay time consisting of delay offset and auto tracking delay time
shouldn’t be more as the maximum memory capacity of the
delay (see technical specifications). Otherwise it produces a
memory overflow and an error message will be displayed. The
use of the unit is blocked to prevent deteriorated audio signals at
digital output.

The digital audio delay b45 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.

- generates a new audio frame structure (is deleting all former existing
embedded audio!)
- is embedding selected TX group as first audio group within SDI stream
- necessary if no audio was embedded before
CASCADE
- generates a new audio group as selected (TX group) within existing
frame structure (is overwriting all data of this group if it was already
existing)
- necessary if a new group should be embedded and if audio in other
groups was embedded previously
- is matching ideally the structure which was generated by PACK mode
(It is recommended to use PACK mode for generating audio
structure and embedding the first group before using CASCADE to
embedd further audio groups!)
Please note: As long as PACK and CASCADE are not set the embedder is
inserting in the group which is determined by RX group selection. The
embedder is replacing the existing audio if it was embedded previously.
If group 1 is selected and no audio structure is existing at the input the
embedder is switching to PACK mode for group 1automatically!
If group 2,3 or 4 is selected and no audio structure is existing for this group
the embedder is not inserting audio data (use PACK or CASCADE!).

ADJUSTMENT OF
DELAY TIME
The digital audio delay b45 is a programmable audio delay.
It is to control by recalling of presets. It has four preset buttons
with which the appropriate preset is called on in each case. In a
preset, all parameters which can be adjusted at the device are
contained. Therefore, one will normally define four operating
states, to store them as presets. The desired device function
can then be activated fast and simply by calling the
corresponding preset (at the device or by external control). The
parameters displayed in the LCD display can be changed with
the PARAMETER knob.

Note: After finishing of adjustment of delay time EXIT button
switches back to main display without permanent storage of
changed values. If you want to store adjusted delay time into
preset you have to store them by „learn preset key“-mode (see
5.4).
