RB-DEED8 – Dolby E Encoder
Fig 1-1: RB-DEED8 Front Panel.
The RB-DEED8 is a stand-alone Dolby E Encoder. Dolby E encodes up to 8 channels of
audio into two channels of an AES digital audio stream.
The audio inputs to the Encoder come from the external digital audio inputs via the BNC or
D-type connections on the rear panel.
The digital audio I/O connections are transformer-coupled balanced line interfaces and can
be configured to be either 75ohm (AES 3ID) or 110ohm (AES 3) impedance through either a
BNC or via the D-type connector. These connections are paralleled, allowing one type to be
used per input or output.
The metadata used for the encoding process can be selected to come from either the
external 9-pin D-type on the rear panel or by settings stored internally.
There is also remote I/O available from the rear panel through a 25 way D-type connector.
These are fully configurable.
The unit is controlled locally through the front panel display but can be remote controlled
via an Ethernet connection using the Sonifex SCi software.
There is independent level control for every channel, which can be adjusted from -24dB
through to +24dB in 0.5dB steps.
RB-DEDD8 – Dolby E / Dolby Digital Decoder
Fig 1-2: RB-DEDD8 Front Panel.
The RB-DEDD8 is a stand-alone Dolby E & Dolby Digital Decoder. It decodes a Dolby E or
Dolby Digital bitstream. The outputs from the decoder are transmitted on a BNC or D-type
situated on the rear panel. The encoded Dolby bitstream is also available via a dedicated
output on the rear panel.
The digital audio output connections are transformer-coupled balanced line interfaces
and can be configured to be either 75ohm (AES 3ID) or 110ohm (AES 3) output impedance
through either a BNC or via the D-type connector. These output connections are paralleled,
allowing one type to be used per output.
