MEASURING DATA
Fx
70
Agreements:
•
All Level, Frequency Response and Distortion Measurements are performed with "AUDIO PRECISION
SYSTEM ONE". Generator impedance 25 ohms, Analyzer impedance 100 kohms.
•
Levels measured with f=1 kHz.
•
The noise levels measured at the outputs refer to the nominal output level of +18dBm.
•
Tolerances of the level values: +/-1 dB.
•
All Distortion measurements are performed with a measurement bandwidth of 10 Hz - 22 kHz, without filter.
Measured is THD+Noise.
•
Measurements at the original signal with EFFECT OFF.
•
0 dBu = 775 mV rms
•
Operating voltage and current are measured with "PHILIPS MULTIMETER PM 2517X".
•
Power Consumtion is measured with "Zares Wattmeter".
•
Recall of the Service Presets: see table service functions Fx 70 (page 48) and service presets (page 50)
Note:
For operation of some functions (e.g. storing of programs) and explanation of parameter
functions the operating manual is necessary.
