1-4-9. Frequency Response 1-4-11. S/N Ratio
? 1
Set the ¡nput and output leveis to nominal as
in previous paragraphs and connect an osciliator
to the input jack and a wide ranga (more than
100 kHz) íevel meter to the output jack.
Frequency response rangas are as follows:
MIC IN—PGM OUT 20 Hz-30 kHz ^2
Other Inputs —Other Outputs
20 Hz-30kHz _+^5dB
1-4-10. T.H.D.
T.H.D. is aiso measured with the input and out
put leváis set to nominal as previously described.
Connect a low distortion osciliator to the input
jack, and a 30-kHz L.P.F. and a distortion
meter to the output jack. Set the osciliator
output to 1 kHz and read the distortion meter.
S/N ratio should be measured with the input and
outupt lavéis set to nominal as previously
described and a 150-ohm dummy load con-
nected to the MIC IN connector.
