OPERATIONS

Congratulations on joining the thousands of proud, satisfied owners of
quality stereo components from Sansui, the audio specialist.

The AU-505 is a 90-watt integrated amplifier loaded with many state
of-the-art features and distinctively styled with its sophisticated satin-
black front panel, walnut~finished side panels and rational layout of
controls and switches. Among which are such convenience features
as a Tuner Selector to let you instantly switch to radio reception, a
Mode Switch to select between stereo and mono playback, high and
low filters, and provisions for connecting and selecting two pairs of
speaker systems.

Beyond and above these features, the AU-505s tonal quality, like that
of all other Sansui AU series amplifiers, has been perfected and proven
not only by precision electronic measuring instruments, but through
repeated listening tests in a wide variety of acoustic environments.
This manual and the enclosed reference sheet have been prepared to
guide you in operating and caring for your AU-505 correctly. Please

read them once carefully, and retain for future reference.
