DIGITAL AUDIO CONVERTERS

Auto Mode 

Here, the unit is synchronised to an external source, using the digital audio sync, or to the 
TTL level Word Clock. If no sync signal is present the unit runs from the onboard master 
clock at a rate selected by the front panel control (32kHz, 44.1kHz, 48kHz, 88.2kHz, 96kHz, 
176.4kHz or 192kHz).

Auto Lock Mode 

This operates like the auto mode except that if no sync signal is present the unit will run at 
the closest master clock rate to the last locked incoming signal. The FREQUENCY LED will 
indicate the synchronised sample frequency.

When operating in sync modes, the SYNC button flashes whenever the unit is not 
synchronised to the incoming sync signal. 

There are 2 further push-button switches (INPUT1 & INPUT2) that are used to select the 
input connector used for each of the 2 sample rate converter circuits. These switches select 
between AES/EBU, S/PDIF and TOSLink optical connectors.

A red LED indicates when power to the RB-SC2 is on.

Installing the Optional Video Sync Boards

There are 2 optional video sync boards which can be used to synchronise the outputs of 
the RB-SC2 to a 48kHz sample rate:

RB-SYA - The Analogue video sync board will accept a composite signal of NTSC (525), PAL 
(625) & SECAM (625) signals covered by SMPTE-170-M (NTSC) and ITU-R BT.470-6 (PAL & 
SECAM).

RB-SYD - The Digital video sync board will accept 270Mbps SD-SDI and HD-SDI signals 
covered by SMPTE-259-M-C (SD) and SMPTE-292M (HD).

Opening the RB-SC2

Warning : The power must be switched off at the supply or the power lead must be 
disconnected before attempting to open the unit. Removal of the cover can expose 
dangerous voltages.

1. Remove the 4 screws in the corners of the rear panel. 
2. Remove the 4 screws on the top and bottom panels which hold the rear panel in place (2 
on the top and 2 on the bottom).
3. Remove the screw on the front panel underneath the CS DATA button.
4. Slide the rear panel and main PCB backwards out of the metal chassis giving you internal 
access. 
5. Remove the rubber grommet/bung on the rear panel which covers the hole for the video 
sync connector.
6. Remove the 2 screws  from the bottom of the sync card pillars and, making sure to keep 
the plastic washers in place at the bottom of the pillars, fit the 20 way pin header into the 20 
way connector on the RB-SC2 motherboard. 
7. Underneath the board , insert the 2 screws to fix the board in place.
