OPERATION

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

As the worlds foremost audio-only specialist, Sansui has spared no
effort in making the TU-505 one of the most sensitive, most versatile
tuners ever marketed.

It is packed with state-of~the-art circuitry and a multitude of sophisti
cated features. The easy-to-tune wide dial with linear FM scale, noise-
free FM tuning, FM antenna switch that attenuates exceedingly strong
stations, and convenient tape recording outputs are just a few examples.
It is distinctively styled with a refined satinablack front panel, walnut
side panels and a highly rational layout of controls and switches.

This manual and the enclosed reference sheet have been prepared to
guide you in operating and caring for your CPU-505 correctly. Please
read them once carefully, then retain them for future reference.

SETTING UP YOUR TU.505

Before you insert the power cord into a wall AC
outlet, be sure to make the following preparations.
FM Antenna: Connect the T-shaped feeder cable
antenna supplied to the tuners FM 3000 terminals.
Adjust the tuner for FM reception and stretch the
antenna to afull T shape, then adjust its height
and direction until you obtain the best reception.
AM Bax: Antenna: In areas where broadcast
signals are sufiiciently strong, clear AM reception is
obtained simply by pulling the built-in AM ferrite
bar antenna away from the rear panel.

Amplifier: Connect the OUTPUT terminals of
the tuner with the TUNER or AUX terminals of
your amplifier (integrated amplifier or preamplifier),
using the pair of pin plug cables supplied. Be
careful not to confuse the left and right channels.
Tape Deck: If you connect the tuner to a tape
deck, you can record directly from the tuner. Con-
nect the TAPE REC terminals of the tuner with
the recording input terminals of your tape deck,
also using pin plug cables.

FM/AM RECEPTION

1. Turn the Selector Control to PM AUTO or
AM, whichever you may wish to hear.

2. Select the desired FM or AM station by turn-
ing the Tuning Control. The station is correctly
tuned in when the Signal Meter pointer has swung
as far to the right as possible.

If the FM station received is broadcasting in stores),
the FM Stereo Indicator will illuminate.

HINTS FOR BETTER
RECEPTION

9T0 receive a weak FM station

Turn off the FM Muting Switch and then tune in
the desired station. With the FM muting circuit at
work, the interstation noise commonly heard during
FM tuning is shut out but weak stations may also
be cancelled.

0T0 suppress loud noise during AM. or
FM reception

Set the Noise Suppressor Switch to IN. If no loud

noise is heard, he sure to keep it at OUT.

OWhen receiving an excessively strong
station

If the FM signal is too strong, the received sound

may be distorted and crack. In this case, change the

FM LocalfDistant Antenna Switch over to LOC.

Otherwise, he sure to leave it at DIST.
