Teac AG-550 - Operating Controls and Unit Placement; Unit Placement Recommendations; Front Panel Controls Explained

Precautions
Placement of the Unit
As the unit incorporates a powerful
amplifier, heat is radiated from the back
and top of the unit; the unit should be
installed in a well ventilated area. Avoid
installing where it would be exposed to
high temperatures, direct sunlight, high
humidity and dust. If connection wires are
too long, particularly those used to
connect the speakers, it may result in
degradation of the sound. Therefore, keep
the connection cables as short as
possible.
Controls and Connectors
* The buttons with a mark can
be operated with the remote control
(as long as the power cord of the
receiver is plugged into an AC wall
outlet).

headphones with a standard 1/4" (6.35 mm
dia) stereo phone plug.
@® GRAPHIC EQUALIZER Controls
These controls are used to adjust the 5
frequency bands that result from dividing
the 83 Hz - 12 kHz frequency range into 5.
When these controls are moved in the "+"
direction, response in the corresponding
frequency band is boosted. When they are
moved in the “-" direction, response is
decreased. The characteristics in each
band can be emphasized or de-
emphasized by a maximum of 12 dB
NOTE:
Set to the "0" position to obtain flat
response.
@® HI-FILTER Button

case, set this button to ON to reduce noise.
To receive FM broadcasts in stereo again,
press this button to return to the stereo
mode (so that the STEREO indicator lights).

corresponding to the button pressed.
@® TUNING buttons
These buttons are used to tune to
broadcasts in the AUTO and MANUAL
tuning modes.
In either mode, when the upper limit
frequency is reached, the frequency
changes to the lower limit frequency then
tuning starts again in the direction of
higher frequencies. When the lower limit
frequency is reached, tuning restarts from
the top frequency.
