MEGURO Automatic Distortion Meter MAK-6571C The MAK-6571 is designed to speed up measurement of distortion in radio sets, stereo amplifiers, tape recorders, and other audio equipment. Measurements of the total harmonic distortion, THD, at 400Hz or l000Hz or any External frequency can be easily made. An advantage of this instrument is the ability to measure distortion even when there is a small variation in the input signal level. Again, an efficient high-pass filter system is used making it possible to accurately measure distortion in presence of wow flutter in the reproduced signal from a tape recorder or a phono-player. This instrument can be used as a level meter, when required, for signal inputs, in the 10mV to 100Vrms, range in the 20Hz to 100kHz band. FEATURES : 1. Measurement of low distortion levels is possible. 2. Simultaneous measurements of distortion and level. 3. No need for initial input level calibration-a timer saver. 4. Distortion and input small levels can be measured at the same time-two meters are used. 5. Distortion can be accurately measured even with variation in the input signal level, or in presence of wow flutter in tape recorders, etc. 6. Total harmonic distortion is indicated without regard to "AC hum''. Two independent meter panels, graduated in Volts, Decibels and percent values. Four Functions: Level; 400 Hz; 1000 Hz Automatic. Seven Distortion Ranges in Percent scale (%): Cal; 30; 10; 3; 1; 0.3; 0.1 % Seven Distortion Ranges in Decibels (dB): 0; -10; -20; -30; -40: -40; -50; -60 dB Nine Input Volts Ranges:100; 30; 10; 3; 1; 0.3; 0.1;0.03;0.01 volts Nine Input Ranges in Decibels (dB): +40; +30; +20; +10; 0; -10; -20 ;-30;-40 dB Distortion measurement: fundamental wave: 400 and 1000 Hz; 3rd harmonic: 300, 315, 333 and 1, 2, 3 kHz Fundamental rejection characteristics: < -76dB at 400 and 1000 Hz Frequency Range: 20 Hz to 100 kHz Measuring Range: 1mVrms to 100Vrms Accuracy: +/- 3%. 290 x 160 x 290 mm / 11.4 x 6.3 x 11.4 inch Weight : Approx 13lbs (5.9 kgs)
