DI GI TA L AUD IO CON VERTERS 1 1 RB-ADDA Combined A/D and D/A Converter Introduction Fig 1-1: RB-ADDA Front Panel The unit operates in four modes: Master Mode - In this mode the unit receives an analogue audio signal, which is digitised and formatted for digital serial transmission (IEC958). The necessary clock signals are generated internally from an on board master clock at a selectable rate (32kHz, 44.1kHz, 48kHz, 64kHz, 88.1kHz or 96kHz).
1 DI G I TA L AUDI O CO NVE R T E R S For the digital output, there is a switch available to define the content of the channel status bits embedded within the digital audio stream. The channel status bits can be set to either Professional or Consumer Mode. DIGITAL AUDIO CON VERTERS - RB -A D DA System Block Diagram Fig 1-2: RB-ADDA System Block Diagram Front Panel Indicators The LED on the front panel is normally red to indicate that power is present on the unit.
DI GI TA L AUD IO CON VERTERS 1 RB-ADDA Inputs XLR Analogue Inputs (Left and Right) The XLR 3 pin sockets used for the left and right channel inputs are electronically balanced and have an impedance of greater than 10kΩ bridging. Each XLR has the following connections: Pin 1: Screen. Pin 2: Phase. Pin 3: Non-phase. Input Level Adjustment The input gain can be individually adjusted for left and right channels by dipswitches and through pre-set potentiometers accessible on the rear panel.
1 DI G I TA L AUDI O CO NVE R T E R S DIGITAL AUDIO CON VERTERS - RB -A D DA Output Level Adjustment The output gain can be individually adjusted for left and right channels through the rear panel by dipswitches. Each output gain can be set for a signal of full-scale digits in the digital domain to give +12, +18 or +24dBu output on the XLR connectors (see Fig 1-4). The consumer output on the phono connector has a further 10dbU attenuation incorporated.
DI GI TA L AUD IO CON VERTERS 1 Status Select Switches These switches are used to determine the status or content of the digital signals. The type of information encoded in the channel status bits of a digital audio signal can be professional or consumer and is determined by switch 1. If de-emphasis is selected (switch 2) the RB-ADDA will decode 50/15µs emphasis when indicated by certain channel status bits in the incoming digital audio data.
1 DI G I TA L AUDI O CO NVE R T E R S In Slave Sync Mode, switch position D, the digital output sample rate follows the digital input. When the digital input signal is not present the digital output is turned off. The following table, also printed on the top of the unit, summarises the above settings and shows the sample rate generated by the internal clock generator in master and auto sync modes.

If synchronising to an external signal there are several modes causing different actions in case of loss of the synchronising signal.
DI GI TA L AUD IO CON VERTERS 3 Front Panel Indicators Front Panel LED The LED on the front panel is normally red to indicate that power is present on the unit. However, it also has a secondary role to indicate the status of the digital inputs Fast flashing between red and amber – indicates a loss of digital input signal. Slow flashing between red and amber - when not in master mode this indicates the absence of a synchronising input.

DI GI TA L AUD IO CON VERTERS 3 In Master sync mode, switch positions 0 – 5, the digital output sample rate is simply set by, and locked to, the internal on-board clock generator. No sync signal is used or required. In Auto sync mode, switch positions 6– B, the digital output sample rate follows the sync input. When the sync signal is not present the output sample rate will be set by, and locked to, the internal on-board clock generator at a frequency determined by the switch position.

A front panel DIPSwitch block is used to decide whether the unit is synchronised to Input1, Input2, the AES/EBU sync input, the wordclock sync input or an optional video sync board. A front panel SYNC button selects the synchronisation mode of the unit and the button flashes whenever the unit is not synchronised to an incoming sync signal.
S YNC HRO NISERS, D EL AYS & S I LENCE D E TEC TORS 10 Front panel LED indicators by the MAIN and AUX buttons show individually left and right programme and alarm conditions for both the main and auxiliary inputs. A powerful feature of the RB-DSD1 is that by using the Sonifex SCi serial software, the unit can be programmed for different delay durations, levels and switching functions so that you can programme the unit for your specific application.
