2 RB-DSS10 10 Way Stereo Digital Source Selector

Introduction

Fig 2-1: RB-DSS10 Front Panel.

The RB-DSS10 10 Way stereo Digital Source Selector is a 1U rack-mount which produces
an AES/EBU and S/PDIF level digital audio output from 10 selectable AES/EBU or S/PDIF
digital input signals. There are 10 illuminated front panel push buttons, which select and
indicate the current channel selection. The selection and indication is also available through
a remote connector on the rear panel. To stop accidental front panel selection there is a
remote input to inhibit the front panel buttons.
The digital receivers in this unit are fully 24 bit, 96kHz capable. When an input is selected
from the front panel, or remotely, the unit will attempt to capture the incoming signal
on either the AES/EBU or the S/PDIF signal inputs, with priority given to the AES/EBU
input. If the AES/EBU signal becomes locked while the S/PDIF signal is routed, the unit will
automatically switch to the incoming AES/EBU signal.
Once the receiver has successfully locked to a digital input, the LED illuminates, the tally
is made, and the audio is routed simultaneously to both the digital audio outputs and
converted to analogue audio for monitoring on the front panel headphone socket. If the
incoming audio signal is not present, the push button LED and remote tally flash to indicate
that the incoming digital signal is missing.
The headphone output has its own volume control, which is independent of the level
adjustment for the main outputs, and has a maximum output level of +12dBu.
As well as routing the selected audio signal, the unit will also route a remote signal input
through the remote connector to the selected input source, for starting external audio
equipment, such as a CD player.
There is a designation strip on the front panel, useful for giving the buttons a meaningful
description.
The LED on the front panel is used to indicate that power is present on the unit. However, it
also has a secondary role to indicate whether the selected channel is routing the AES/EBU
(red LED) or S/PDIF input (amber LED).
