AUDIO CONNECTIONS
• Ground Loops:
If ground loop problems are encountered, never disconnect
the mains earth, but instead, try disconnecting the signal screen
on one end of each of the cables connecting the outputs of the
1973 to the patchbay. If such measures are necessary,
balanced operation is recommended.
• Interference:
If the 1973 is to be used where it maybe exposed to
high levels of disturbance such as found close to a TV
or radio transmitter, we advise that it is operated in a
balanced configuration. The screens of the signal cables
should be connected to the chassis connection on the
XLR connector as opposed to connecting to pin1.
The 1973 conforms to the EMC standards.
A typical setup for connecting the 1973 would be by the use of a Y-lead between the two input and output
xlr’s on the rear of the 1973 and insert point for the respective channel of the desk - this would be repeated
for both channels. The wiring of the Y-lead can be seen below.
The inputs and outputs are electronically balanced on conventionally wired XLRs (pin 1 screen, pin 2 hot,
pin 3 cold and XLR shell is connected to chassis). The operating level is nominally +4dBu. Balanced use is
recommended.
