POWER OUTPUT
Playback a tape containing a sine wave of 1,000 Hz
recorded at O VU on a standard recorder. Measure the
voltage at the output of the recorder to be tested when
terminated with 8 ohms resistance.
Then use the following formula:
P= Desired output (watts)
2
p= oe E = Measured voltage (R.M.S.)
R=8
CROSS TALK (Cross talk between the tracks)
(TAPE)
Tape direction
Tape directio
As shown in the figure, first record a 1,000 Hz sine wave
on track No. 3 at + 3 VU level. Next, remove the 1,000
Hz input signal and record under a non-input condition.
Then, playback the tape on track No. 3 and No. 1
(reversed condition of tape) through the 1,000 Hz
B.P.F. (Band Pass Filter, Sensitivity ... 1:1) and obtain
a ratio between the two from the following formula.
= Eo
d
C= 20 log ey ( b)
C = Desired cross talk ratio (db)
E, = 1,000 Hz signal output level Ee
E,= 1,000 Hz cross talk output level
E , = Non-input signal record level BRERA
