RB-DA6
6 Way Stereo Distribution Amplifier
The RB-DA6 is a 1U rack-mount high performance 6 way stereo
distribution amplifier for splitting a source into a number of different
outputs. The RB-DA6 has 1 stereo input and 6 stereo outputs. It
can also be configured so that 1 mono input can be distributed to 12
outputs by use of a switch which is recessed on the front panel to
prevent it being accidentally knocked.
The XLR-3 inputs and outputs are electronically balanced and can
be wired unbalanced. Each output is individually buffered so that a
short circuit on one output won’t affect the others.
The left and right input gain controls (normalising) are pre-set
potentiometers accessible through the front panel.

Headphone Distribution Amplifier
The RB-HD6 headphone distribution amplifier is a 1U rack-mount
which distributes stereo audio to up to 6 different sets of headphones,
or can be used as 6 independent headphone amplifiers, each with
their own input and volume control. A typical application might be to
provide common headphone feeds for guests in a radio studio, with a
separately derived feed, perhaps including talk-back, for the
presenter.
The main stereo input is on XLR-3 connectors on the rear panel. A
stereo/mono input select switch sums left and right outputs to provide
a mono feed to the headphones.The unit can receive an override
audio signal via a jack socket for each output channel. Plugging in the
jack plug will divert the headphone output from the master audio
signal to the audio present on the jack plug. The override audio inputs
can also be individually configured as parallel outputs, by setting
internal jumpers.
The master volume control adjusts overall level of the 6 outputs and
does not affect the level of channels using the override inputs. The
master volume can be disabled by internal jumpers.

Digital Audio Distribution
RB-DDA6A
mixing desk to multiple digital recorders, or feeding
multiple studios with an output from a DAT machine.
The RB-DDA6A 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 re-normalising to standard digital audio
levels.
Range Features:
It has a single XLR-3 female AES/EBU audio input which
is distributed to 6 off XLR-3 male AES/EBU outputs.
All are equipped with IEC mains lead
and instruction manual.
Applications include distributing audio from a digital
In-house design and manufacture
ensures high quality control standards.
They are manufactured as either 115V
60Hz or 230V 50Hz and all have a front
panel LED power indicator.
Manufactured within ISO9000 standards
and guaranteed CE compliant.
Housed in eye catching red anodised
aluminium cases.

RB-DDA6S
6 Way S/PDIF Digital Distribution Amplifier
The Redboxes in this brochure can be rackmounted using the 1U RB-RK1 rack front kit,
except the RB-DA6 & RB-HD6 which are
already rack-mounted.
The RB-DDA6S digital distribution amplifier is similar to
the RB-DDA6A except that it is used for distributing
digital audio data in S/PDIF format.

Uses include audio distribution at 16 bit 44.1kHz from a
consumer CD player to multiple digital recorders,
distribution of high quality 24 bit 96kHz signals from
digital mixing desks to recorders and connection of the
output of, say, a DVD player to multiple studios.
It has a single S/PDIF audio input which is distributed to
6 off S/PDIF audio outputs at the same level and
condition as the input signal. It can accept input sample
rates in the range of 30kHz - 100kHz, and bit rates of 16,
20 and 24 bit.

All are screw mountable as standard and
are either rack-mounted or have the
option to be rack-mounted.
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.
