It is possible to substitute it with MIDI Monitor.
Measuring Conditions:
•
It is time when the value of the Noise level, crosstalk, and the Distortion Rate used 20KHz LPF of measuring
instrument ATS-2 and it is regulated.
•
Input Signal for Test: Sine wave of 1KHz(RS=150 ohm)(Distortion Rate: 0.001% or less), unless otherwise speci-
fied.
•
Load Conditions of Analog Input/Output plug for Test:
