DESCRIPTION
2
The programmable digital audio delay b45 is a professional
studio device for delaying of 4 digital audio channels.
Digital audio delay b45 is working with a new processing
algorithm developed by Jünger Audio. It is possible to change
the delay time "glitch free" - without changing of pitch, without
noises or clicks. Readjustment of audio delay time under live
conditions - inaudible and fast done with the digital audio delay
b45!
The four channel configuration matches the audio capability of
Digital VTR's. B45 can be used as remotable and programmable
audio delay in digital video systems.
The unit is programmable,easy to operate and requires only a
limited number of settings for fast and efficient audio processing.
• 4 channel programmable digital audio delay
• "glitch free" changing of delay times
• auto tracking function
• up to 1,2 s delay time per channel
• user friendly preset and recall system
• external sync mode, AES/EBU or VIDEO
• RS-422 interface for serial remote
• GPI interface for parallel remote control input, tally output

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.

LINK FUNCTION /
CHANNEL
CONFIGURATION
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).
2.5
DISPLAY OF DELAY
TIME
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.
2.6
VIDEO FORMAT 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.
