Audio Precision Portable One Plus Access User Manual

Analyzer Inputs and Generator Outputs
Electrical connections between a device-under-test and the test
instrument are typically made with test cables. Analog test cables for
the Portable One Plus Access should have XLR connectors on one end
for connection to the test instrument. The other end of the cables must
have a connector appropriate for the device-under-test. Adapters may
be used to adapt a standard cable to the device or test instrument.
Suitable cables and adapters may be purchased from Audio Precision.
If the device-under-test uses balanced XLR connectors, the
connections can be made directly with XLR cables.
When cables or adapters for unbalanced connectors are used, pin 2 of
the XLR connector should connect to the signal conductor and pin 3 of
the XLR connector should connect to the ground. Also be sure to
select an unbalanced generator configuration (see page 3-4).
The Portable One Plus Access’s Generator Outputs should be
connected to the analog inputs of the device-under-test. The Portable
One Plus Access’s Analyzer Inputs should be connected to the outputs
of the device-under-test.
For single channel devices, use only the Channel A input and output
connectors. For stereo (or 2-channel) devices, Channel A is usually
used for the Left channel and Channel B for the Right channel.
