Audio Precision Portable One Plus Access User Manual

The generator’s output impedance and balanced/unbalanced
configuration is selected on the Generator Only Panel in Analog
Generator Control Mode. Follow this diagram to get there:
The lower center soft key selects the generator output impedance and
configuration. The choices are ‘40 Ω UNBAL’, ‘40 Ω BAL’, ‘150 Ω
BAL’ and ‘600 Ω BAL’.
If your device-under-test has unbalanced inputs, you should select the
40 Ω unbalanced configuration.
If your device has balanced inputs, the 40 Ω balanced selection is
usually the desired choice. The 150 Ω and 600 Ω selections are
generally only used with devices that have an equivalent input
impedance. Check the input specifications for your device. For
devices with higher input impedances, choose 40 Ω.
