AUDIO CONNECTIONS
A typical setup for connecting the 1974 would be by the use of a Y-lead between the two input and output
xlr’s on the rear of the 1974 and insert point for the respective channel of the desk or interface for the digital
workstation - 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 nom4dBu. Balanced use is
recommended.
For connecting the 1974 to a mixing desk use the insert points as shown in the following diagram:
Alternatively, if you are using a digital workstation and have an audio interface that does not have insert
points, connect it to the analogue send (out) and return (in) of the relevant channels via four XLR to XLR/
jack cables. See your interface and software user manuals for the best procedure.
• 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 1974 to the patchbay. If
such measures are necessary, balanced operation is recommended.
• Interference:
If the 1974 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 1974 conforms to the EMC standards.
