Digital AES/EBU through:
This XLR socket will carry a parallel digital
output signal, which is fed either to the BNC
or XLR digital input. There will be a format
conversion inside the O 500 C, so any S-PDIF
signal in the BNC input will be an AES/EBU
signal on that XLR output. This signal may
now be fed to a second O 500 C and the user
may select for the L or R channel from the
digital data stream.
Subwoofer:
This XLR output will carry the analog output
signal from the digital controller, which is
provided for an external, optional subwoofer.
This output will only be active, if a special 4-
way setup has been loaded for the O 500 C.
2.2.2 Variety of Connections
Cables
The figures 2.2/3 to 2.2/5 show the pinning of
the cables which are used in the variety of
connections, described in the following
passages:
Fig. 2.2/3 shows all balanced connections,
such as to a studio console with balanced
outputs, also for the digital AES/EBU
connections. When using AES/EBU-
connections, please make sure that your cable
has a characteristic impedance of 110 Ohms.
Do not use ordinary XLR cables as normally
used for microphones or Line-levels!
To connect the O 500 C to analog sources
from consumer / HiFi units, an adaptor cable
as per Fig. 2.2/4 should be used. Although
Fig. 2.2/4: Adapter from cinch to XLR
Fig. 2.2/5: Adapter from cinch to BNC
Fig. 2.2/3: XLR standard cable
most of these units do not have a mains earth
connection (Euro mainsplug) the receivers,
tuners or TV-systems often are connected to
antennas, which are normally grounded. In
this case the groundlift should be switched to
ON and the O 500 C input should be selected
for „transformer balanced input“. If the hum
problem still remains, PIN 3 on the XLR plug
should be disconnected (cut), and the
shielding wire on the cinch plug should not
be connected.
Connecting the O 500 C to a consumer / HiFi
unit with a digital S-PDIF output, a connection
cable as seen in Fig. 2.2/5 is needed, in case
there is no BNC output on that unit.
Examples for connections
In Fig.s 2.2/6 to 2.2/9 are some examples how
to connect the O 500 C to various signal
sources.
