3. Recording System
Mode : REC mode — PLAY mode
Test tape: Blank tape
Measurement points : LINE OUT
Adjustment Item Preliminary Input Signal Adjustment Point | Measurement Method / Value Adjusted
1, Record/play output | Connection : Fig. 6-10] 1kHz, Check only With the INPUT control in the
level +6dBV (RCA LINE) condition of 2's step 1, set the
Filter : OUT -44dBm (XLR MIC) deck to RECORD mode.
The output level at this point
should be as follows :
+6+1 dBV (10 kQ load)
2. Record/ play 20Hz--20kHz, Check only With the deck in the condition
frequency response *6dBV (RCA LINE) of step 1, when the input
signal varies from 20 Hz to 20
kHz, the record/play frequency
response with respect to the
1 kHz output level should be
as follows :
20 Hz to 20 kHz +08 dB
3. Recording S/N Connection : Fig. 6-10} No input Check only The S/N ratio with respect to
ratio the record/play output level in
22 kHz LPF: IN step 1 should be as follows :
IEC- A : IN 88 dB or more (LINE)
70 dB or more (MIC)
4. Record/ play Connection : Fig. 6-10] 1kHz, Check only The distortion factor when the
dynamic range -54dBV (RCA LINE) input signal is recorded with it
60 dB Amp. lowered by 60 dB from the
400 Hz HPF : IN level in step 1 and played,
30 kHz LPF : IN should be 4.0 % or less and the
22 kHz LPF : IN dynamic range 88 dB or more.
IEC- A : IN
5. Record/ play Connection : Fig. 6- 10| 1kHz, Check only When the deck is in the
channel separation *6dBV (RCA LINE) condition of step 1, the ratio
22 kHz LPF : IN -44dBm (XLR MIC) between the output when a
ІВС-А : IN (Input terminal of one| signal is input to one channel
channel should be and the output at the other
grounded.) channel should be as follows :
85 dB or more (LINE)
80 dB or more (MIC)
6. Record/ play Connection : Fig. 6-10| 100Hz, 1kHz, 10kHz, Check only 0.007 % or less
distortion factor
400 Hz HPF : IN
30 kHz LPF : IN
22 kHz LPF : IN
+6dBV (RCA LINE)
