Redbox are a range of audio and video interfaces designed for use in critical
broadcast applications where the product needs to be powered 24 hours a day, 365
days a year. Manufactured to the highest standards in our UK offices, utilisation of
the finest components and critical quality control techniques ensure that your
Redboxes work every time, for years to come. They are “fit and forget” products - you
can set them up, fit them in your installation and then forget about them.

RB-ADDA Combined A/D and D/A Converter
Uses:
•To connect an analogue line level
audio signal into a digital mixer.
•To connect a digital recorder to an
analogue mixer in both directions.
•To convert an analogue amplifier
signal to an S/PDIF or AES/EBU input
on a mixer.
The RB-ADDA A/D and D/A converter is a 1U rack-mount which produces an
AES/EBU or S/PDIF level digital audio output from a balanced XLR or unbalanced
phono stereo audio input. It also produces a stereo balanced XLR or unbalanced
phono output from an incoming AES/EBU or S/PDIF digital input signal.

Digital Audio Converters

www.sonifex.co.ukwww.sonifex.co.uk
Features:
•Front panel control.
•Operation up to 192kHz.
•AES/EBU & wordclock synchronising
inputs, so that the A/D and D/A
sections can operate independently.
The RB-ADDA2 A/D and D/A converter is a 1U rack-mount which produces an
AES/EBU, S/PDIF or TOSlink optical level digital audio output from a balanced XLR
or unbalanced phono stereo audio input. It also produces a stereo balanced XLR or
unbalanced phono output from an incoming AES/EBU, S/PDIF or TOSlink optical
digital input signal.

RB-SC1 Sample Rate Converter
Features:
•Superb conversion quality.
•AES/EBU and S/PDIF inputs and
outputs.
•AES/EBU,S/PDIF and TTL wordclock
synchronizing inputs.
•Sample rates up to 24bit 96kHz.
Ideal for the transfer of digital audio between different digital equipment, the
RB-SC1 sample rate converter standardises the sample rate of a digital audio
signal to one of 32kHz, 44.1kHz, 48kHz or 96kHz, or to a synchronising input. Both
audio inputs and outputs have push-button switches to select either AES/EBU or
S/PDIF. The synchronising input can be selected from one of AES/EBU, S/PDIF or
TTL word clock.

RB-SC2 Dual Sample Rate Converter
Features:
•Supports sample frequencies up to
176.4kHz & 192kHz.
•Output sample rate set by internal
clock or external sync.
•Has 2 independent sample rate
converter circuits & can function as a
full bi-directional sample rate
converter.
The RB-SC2 sample rate converter is a 1U rack-mount which produces AES/EBU,
S/PDIF and TOSlink optical level digital audio outputs from a balanced AES/EBU,
S/PDIF and TOSlink optical level digital audio inputs. The sample rate of the outputs
can be set by an internal clock or from various external synchroniser sources.

RB-DAC1 Digital to Analogue Converter
Features:
•Superb quality and pristine audio
clarity with 24 bit, 96kHz operation.
•AES/EBU and S/PDIF digital inputs.
•Both balanced XLR and unbalanced
phono outputs.
•Front panel headphone output with
volume control.
Using 24 bit, 96kHz capable devices, the RB-DAC1 D/A Converter is a 1U rack-
mount which produces a stereo balanced XLR or unbalanced phono output from an
incoming AES/EBU or S/PDIF digital input signal. There is also a headphone output
with volume control for monitoring purposes.

RB-SP1 Digital Splitter and Combiner
Features:
•Can be used for interfacing stereo
and mono signals to digital mixing
desks, e.g. can split a digital stereo
signal into 2 digital mono signals.
•Can handle sample rates up to
96kHz and sample sizes of 16, 20
and 24 bit.
The RB-SP1 digital splitter & combiner is used to interface stereo and
mono AES/EBU & S/PDIF signals to digital mixing desks by splitting the left
and right signals of a stereo XLR to two separate XLR’s, and vice versa by
combining them.
