TAPE SPEED
1. Load and play a TEAC MTT-111 test tape.
2. Using a common slotted screwdriver with a handle completely
insulated from the screwdriver blade, adjust the contro! on the
motor for a reading of 3,000 +5 Hz.
See Fig. 2-3.
3. Check the followings at the beginning and the end of the tape.
Specifications:
Tape speed deviation

4, If the tape speed is out of spec., check the pinch roller pressure
and the tape driving function for correctness, and make sure
the tape path is clean.

SETTING
PROCEDURE
(FOR GENERAL
EXPORT MODELS)
1. Always disconnect the power line cord before making these
adjustments.
2. Remove the top cover* of the deck by removing
the screws
from the sides.
3. Locate the voltage selector, shown in the illustration, to the
front of the power transformer.
4. Loosen the two screws in the shorting bar and move the bar
so that it shorts across the terminals marked with the required
voltage (100, 117, 220 or 240).
5. Retighten the screws and replace the top cover*.
Decks sold in some
limited areas only have a wooden
case
which must be removed by the screws on the bottom of the
deck before setting the voltage selector.
NOTE:
Since the A-550RX employs a DC servo motor, 50 Hz or 60 Hz
operation is permitted without power line frequency adaptation.
