9, With a Test-Set connected to the OUTPUT jacks and using
TEAC Test Tape, the readings listed below should be
obtained at the specified frequencies and tape speeds.
16 kHz 1__dB oor less
PHONES OUTPUT CHECK
1. Place OUTPUT control at the Specified level setting
(400 Hz signal at -8 dB).
2. Connect an 82 non-inductive resistor across the headphone jacks.
Connect Test-Set across the resistor.
3. Test-Set should indicate -24 dB +1 dB,
MINIMUM INPUT LEVEL SETTING
LINE Input:
ik 1. Connect an AF oscillator to the LINE IN jacks.
ina 2. Place MONITOR switch in SOURCE, RECORD EQ and BIAS switches
in HIGH position, and MODE L, R in ON position.
3. Apply a 400 Hz signal -18 dB to the LINE IN jacks.
4, Turn LINE control fully clockwise, adjust VR-451/452 to obtain
the specified output level of -8 dB at OUTPUT jacks.
MIC Input:
[This is a check only. No adjustments are to be made.]
5. After checking VR-451/452, apply a 400 Hz signal at -60 dB to
the MIC IN jacks.
6. Rotate the MIC controls fully clockwise. This should give an
output of -8 dB (specified output level).
NOTE: Return MIC controls fully counterclockwise (CCW) to pre-
vent noise insertion during the following steps.
