Method :

7. REC/PB
Settings 1

Method :

Rated

' Test tape : TTA * 620 (TTA - 119M?)
-Test point : TF2 (L ch), TPS (R ch)
'Adjustment Location : L301 (L ch)

L302 (R ch)
Set to the record mode and adjust so that the
bias voltage leaking to the test point is

minimum level_

Frequency Response Adjustment
- Test tape : TTA — 600 (TTA — 119K)
- Test point : LINE OUT jack
-Input signal :1 kHz/10 kHz (LINE IN)
' Adjustment Location : SFRSOI (L ch)

SFRSOZ (R ch)
Apply a 1 kHz signal and adjust attenuator so
that the output level at the LINE OUT jack is
35 mV.
Record and play back the 1 kHz and 10 kHz
signals and adjust so that the output of the 10
kHz signal is —0.5 dB with respect to that of
the 1 kHz signal.
