Teac A-2300SD - Tape Speed; Flutter; Voltage and Frequency Conversion

7-6 TAPE SPEED
The tape speed should be measured using TEAC flutter free
tape, Model YTT-2003 (7-1/2 ips), YTT-2002 (3-3/4 ips).
These tapes contain a highly accurate 3 kHz tone. Connect
a digital frequency counter to either line OUTPUT jack.
The indicated frequency should be 3 kHz (±30 Hz or less)
for both speeds.
- VOLTAGE CONVERSION -
The A-2300SD (EX) model may be set for 100, 117, 200,
220, or 240 volts. To change the voltage, unscrew the fuse
in the center of the voltage selector plug. Pull out the plug
and reinsert it so the desired voltage shows in the cut-out.
Reinstall the fuse.
7-7 FLUTTER
Flutter should be measured in playback mode using a TEAC
flutter free tape YTT-2003, 2002 and Meguro Denpa Co.,
IV1K668A flutter meter. Values obtained with different
standard or equipment cannot be compared.
Flutter should not exceed value shown.
0.08% (WRMS), 0.18% (RMS) at 7-1/2 ips
0.10% (WRMS), 0.20% (RMS) at 3-3/4 ips
These figures apply to any tape position (such
as full take-up reel, full supply reel or about mid point).
If there is excessive wow and flutter, examine the pinch
roller, belt, motors, capstan shaft, and reel rest for “grease”,
“oil”, “dirt” and/or “wear”. Also examine the tape counter
ass’y for evenness of operation.
7-8 VOLTAGE AND FREQUENCY
CONVERSION
Unit must be set to the power line frequency available.
Improper frequency setting will result in a 20% error
for the Tape speed. (US model is preset to 117V AC and
60 Hz frequency and voltage conversion is not required).
If it should be necessary to convert the A-2300SD deck to
operate from a power source of different voltage of fre¬
quency, it may be easily accomplished as follows;
Fig. 7-7 Voltage Conversion
- FREQUENCY CONVERSION -
1. Remove the power cord and all connecting cables.
2. Take off tape deck rear cover by removing the 6 screws
holding it.
3. To convert the unit from 50 Hz to 60 Hz operation
reposition the capstan belt as shown in the illustration
below.
4. Frequency selector slide switch inside the rear of the
tape deck must be switched to the frequency of the
power line.
5. Reinstall rear cover.
