the mono mode. The system provides line level monitor outputs capable of
driving 600 ohm loads.
The AOS auxillary system provides a unique set of digitally generated test
signals which can be instantly selected and injected into a recorded track. By
digitally generating the test signals their frequency and level are extremely
accurately defined. This assures that crossmodulation test tracks made on the
machine are absolutely standard and readable on the new static crossmodulation
reading system. A unique new Pink Tone signal is also selectable. This signal is
also digitally generated and provides a flat spectrum on 1/3 octave spectrum
analyzers and has the unique property that a three frame burst is all that is
required to measure the frequency response of the recording system.
