User Manual

Thank You
Thank you for choosing the C16A for your SDI embedded audio monitoring needs.
The C16A is just one of many products from the C-Series of audio monitors offered by
Census Digital. Please visit our website www.censusdigital.com for more information.
Overview
The C16A is a compact 2 RU 3G/HD/SD-SDI embedded audio monitoring system
designed to extract up to 16 Channels of embedded audio from an SDI signal for
monitoring.
The C16A has been designed with a simple and intuitive user interface to allow for easy
access to the signals and information you need to monitor.
A large vacuum fluorescent display located on the front panel provides 16 bar graph
VU/PPM meters. An additional bar graph meter is provided for LKFS ITU1770/1771
loudness measurements. A numerical readout of the LKFS and true peak
measurement is also provided. Input signal format data and mode selection information
is also displayed.
Located directly beneath the display are 12 high quality illuminated pushbuttons to
provide intuitive channel source and mode selection.
Also located on the front panel is a high quality mil-spec push to mute rotary shaft
encoder for volume control and a jackfiled style ¼” longframe jack for headset
monitoring.
High quality full range speakers and an efficient class D amplifier provide unparalleled
performance.
One 3G/HD/SD-SDI signal can be connected to the BNC on the rear panel while a
reclocked output is available. Two 3-Pin terminal block connectors also provide a

stereo monitor output. This monitor output follows the signals that are being monitored
on the internal speakers.
