The Digital Interfaces - Joemeek SC4 User Manual

SC4 M&S DAD Stereo Compressor - User's guide
A detented output gain control is calibrated to give 6dB gain in hand and the MS
signal is then decoded back into stereo left and right.
The analogue output stage gives balanced outputs via XLR connectors.

2) THE DIGITAL INTERFACES

(optional on some SC4 models)
Digital inputs are either optical or AES/EBU, at 44.1 or 48 KHz samplerate.
Digital to analogue conversion is to 24 bit standard.
The input to the compressor section is switchable between the analogue inputs
and the digital inputs.
After compression and the analogue output gain control, the decoded audio
signal drives both the analogue output stages, and the analogue to digital
converters.
The clocking of the digital output is selectable: A 'local/remote' switch selects
whether the output follows the incoming clock or generates a local clock.
Another select switch determines the local clock setting; 44.1 or 48KHz. LEDs
show the selected samplerate but they are only illuminated when the selector is
in 'local' mode, or when there is no incoming clock.
When an incoming clock is present, it is indicated by a red LED on the front
panel.
Digital outputs are AES/EBU and optical (SPDif) with an additional pushbutton
on the rear panel which switches 'consumer' or 'professional' mode.
