15. Playback Frequency Response Measurement
SET UP
1. Power voltage:- 50 or GOHzAC voltage rated
for the unit to be used in a market country.
2. TAPE selector switch position:- NORMAL
and CrO, or Fe-Cr.
3. Load:- Measuring instrument input im-
pedance.
4. Measuring output teminal:- LINE OUT.
5. Test tape used:-
MTT-116U (for NORMAL).
MTT-116K (for CrO, or Fe-Cr).
PROCEDURES
1. Play the test tape MTT-116U and MTT-
116K back. Let the 315Hz output Seve! be
OdB as reference level,
2. Read the 40Hz and 10kHz output level
differences from the 315Hz, OdB reference
level.
3. Proceed both for the right and teft channels
in the same manner.
4. For the above measurement, use the test
tape MTT-116U for the NORMAL position
and MTT-116K for the CrO, or Fe-Cr.
Mode: playback

STANDARD
In reference to the 315Hz, OdB signal output
level,
40Hz-6.3kHz...... +2.5dB
6.3kHz-10kHz...... +2.5, —3dB
14kHz...... +4dB
CAUTION
Since the test tapes used may involve some
head azimuth difference, the head azimuth
should be corrected at the highest frequency
of each test tape before measurement.
16. Record-Playback Output Level Measurement
(at LINE OUT)
SET UP
1. Power voltage:- 50 or 60Hz AC voltage rated
for the unit to be used in a market country.
2. Input: 1kHz, —60dB signal.
3. Load:- Measuring instrument input im-
pedance.
4. Level control position:- SRL for recording
operation.
5. TAPE selector switch position:- NORMAL,
CrO, and Fe-Cr.
6. Measuring output terminal:- LINE OUT.
7. Cassette tape used:- TDK AC-211, AC-511
and SONY CS-30.
PROCEDURES
1. Record the 1kHz, —60dB signal in the
normal recording state.
2. Play the recorded signal back. Read the
VTVM indication.
3. Proceed for the NORMAL, CrO, and Fe-Cr
positions each in the same manner.
4. Proceed both for the right and left channels
in the same manner.
Mode: reocrd

STANDARDS
1. NORMAL position: 430mV + 3dB.
2. CrO, position: 430mV + 3dB.
3. Fe-Cr position: 430mV + 3dB.
