RB-DDA6A-2P 6 Way Stereo AES/EBU Digital Distribution Amplifier
with Dual Power Supplies
The RB-DDA6A-2P digital distribution
amplifier is used for distributing digital
audio data in AES/EBU format, repeating
both the audio data and the status
information of the input whilst renormalising to standard digital audio levels.
It has a single XLR-3 female AES/EBU audio
input which is distributed to 6 XLR-3 male
AES/EBU outputs.
Applications include distributing audio from
a digital mixing desk to multiple digital
recorders, or feeding multiple studios with
an output from a flashcard player.
It can accept input sample rates in the range
of 30kHz - 100kHz, and bit rates of 16, 20
and 24 bit. So, it can be used for standard
CD signal distribution at 16 bit 44.1kHz,
as well as for high quality 24 bit 96kHz
recording.
The unit provides redundancy protection
by using two power supply units that can
be supplied from separate mains feeds. The
unit automatically load shares between the
two supplies so that if either supply should
fail the unit will continue to work correctly.
If both supplies fail the input is connected
directly to output 1.
The condition of the two supplies is
indicated on the front panel by two red LEDs
which illuminate to indicate the correct
function of the supply. On the
alarm output connector there is a
changeover relay to indicate the status
of each supply. This is normally closed to
indicate power fail and once the supply
is working correctly the relay activates to
make a normally open contact.
