C16C-2
Dual 3G/HD/SD-SDI + 2 Channel Analog + 1 AES/EBU
Input Audio Monitoring System
User Manual
Overview
The C16C-2 is a compact 2 RU Dual 3G/HD/SD-SDI, +Analog +Digital Audio Monitoring
System designed to provide visual and aural monitoring of two 3G/HD/SD-SDI
additionally the unit can also accept 1 stereo analog audio input and 1 75 Ohm
AES/EBU digital audio input/
The C16C has been designed with a simple intuitive user interface to allow for easy
access to the signals and information you need to monitor.
Three illuminated pushbuttons conveniently located on the front panel provide for input
signal selection. You can choose SDI1, SDI2, or Analog/AES.
A large vacuum fluorescent display located on the front panel provides 16 bar graph
VU/PPM meters along with an LKFS bar graph and numerical readout of the ITU1770-
3/1771 loudness measurements.
Located directly beneath the display are 12 illuminated pushbuttons to provide channel
source selection as well as mode selection.
Also located on the front panel is a military specification push to mute rotary shaft
encoder for volume control and a ¼” longframe jack for headset monitoring. When the
headset is inserted the internal speakers will mute automatically.
A monitor output on the rear panel is provided on two 3-Pin terminal block connectors.
This monitor output follows whatever signal is being monitored on the internal speakers.
Installing a jumper between the I and G terminal of the GPIO 3-Pin connector mutes the
internal speakers and allows the front panel volume control to provide level control over
the external speaker output. Ideal for when you want to control powered speakers.
Internal high quality full range speakers and a class D amplifier reproduce an intelligible
audio signal.
Features
Input Source Selection
SDI 1
Routes SDI 1 input signal to the display for
further source selection to the speakers.
Provides up to 16 channels of embedded
audio.
SDI 2
Routes SDI 2 input signal to the display
for further source selection to the
speakers. Provides up to 16 channels of
embedded audio.
ANALOG/AES
Routes both the stereo analog and
AES/EBU input signal to the display for
further source selection to the speakers.
Source Selection
Once you have chosen which signal to route to the display directly below the easy to
read vacuum fluorescent display are 8 illuminated pushbuttons to select which signal
you want to route to the speakers.
In the case of SDI you can have up to 16 channels displayed on pairs numbered 1
though number 8. When in Analog/AES mode the stereo analog input signal will be
displayed on pair 1 and the 75 Ohm AES/EBU input signal will be displayed on pair 5.
Mode Selection
There are also 4 illuminated pushbuttons are for mode selection. Please note that the
unit functions as a stereo audio monitor unless you are using a different mode.
L
The Left channel only is routed to both speakers
R
The Right channel only is routed to both speakers
SUM
Allows the channels to be summed together to monitor more than one
source at a time.
Lt/Rt
Provides an Lt/Rt downmix of your selected 5.1 source. Select the pair
where your discrete 5.1 mix starts then press the Lt/Rt button which
then selects the 2 pairs beside it and creates the downmix from these 6
channels.
Volume Control
The C16C-2 comes equipped with a high quality mil-spec push to mute optical shaft
encoder for the volume control. Finished with a BIG custom machined aluminum knob
for ease of operator use and longevity.
When the shaft encoder is pushed this will mute the audio signal and the speaker
symbol on the display will toggle with the speaker and an X.
Installing a jumper between the I and G terminal of the GPIO 3-Pin connector mutes the
internal speakers and allows the front panel volume control to provide level control over
the external speaker output. Ideal for when you want to control powered speakers.
Headset
The C16C-2 uses a high quality metal ¼ inch long frame jack like the type used in an
audio patch bay to ensure it can handle the day to day use for many years to come.
When a headset is inserted the internal speakers are automatically muted and the
volume control now controls the headset level.
Speakers
The C16C-2 has two high quality full range speakers powered by an efficient class D
audio amplifier which reproduces and intelligible audio signal.
I/O
All input and output connections are conveniently made on the rear panel.
SDI1 and SDI2 inputs are on 75 Ohm BNC connectors. A reclocked output of SDI1 and
SDI2 are also provided on BNC connectors.
The stereo analog audio input is on two 3-pin pluggable terminal block connectors.
A 75 Ohm AES/EBU input is also provided on a BNC connector.
The external audio output of the C16C-2 is also made using two 3-pin pluggable
terminal blocks.
There is a GPIO connector there for different operating modes such as the external
audio level control using the front panel volume control.
In addition the C16C-2 has an Ethernet connector which allows the user to benefit from
any future software releases and also provides some basic control functions. The
C16C-2 uses the award winning Ross Video openGear Connect dashboard control
system.
Also located on the rear panel is the power source connector. The unit will also be
supplied with the region specific power cord.
DISPLAY
The C16C-2 uses a large high quality VFD vacuum fluorescent display to provide audio
metering and signal status information.
You can display up to 16 channels of 3G/HD/SD-SDI embedded audio at one time for at
a glance audio signal presence.
We use a unique bar graph display which only shows the outline when above the user
defined reference point. Making a unique bi color display which is easy to read quickly.
In addition the C16C-2 also provides an ITU 1770-3 LkFS measurement which is
displayed beside the VU/PPM meters.
