TEST PROGRAM
36
MODX6/MODX7
1. Measurement condition
1-1. Environment
Perform tests under following conditions.
Ordinary temperature (5°C to 40°C)
Ordinary humidity (20% to 90%)
If the test result does not meet the specifications, check again the tests under such conditions as the ordinary temperature (5°C
to 40°C) and ordinary humidity (30% to 90% relative humidity).
1-2. Power voltage
Use PA-150B for the AC adaptor.
The AC power should be 50Hz or 60Hz and the capacity should be 500VA or more.
The voltage should be ±10% of the rating voltage of the adaptor being used.
1-3. Measuring instrument
Make sure that the instruments used for inspections have enough accuracy and precision.
Use the instruments with more than 1M-ohms input impedance.
• Level meter (using JIS-C filter)
• Frequency counter (should be capable of measuring to three places of decimals)
• Oscilloscope
• Oscillator
1-4. Test jig
Following jigs are required for testing.
• Speaker with amplifier
• MIDI cable
• USB cable (A-B type)
• USB flash drive
• Foot pedal (FC3A, FC4A or FC5)
• Foot controller (FC7)
• Monaural plug (150-ohms load) : Noise level check for A/D INPUT jacks.
1-5. Terminal condition
Measure the values at the [PHONES] jack by using a stereo plug unless otherwise specified.
[PHONES] :
Install a measuring plug (L/R ch: 33-ohms load)
OUTPUT [L/MONO]/[R] :
Install a monaural plug (L (MONO)/R ch: 10k-ohms load)
A/D INPUT [L/MONO]/[R] :
Install a monaural plug
1-6. Control condition
Unless otherwise specified, set control knobs as follows. Set others in the default state by turning the power on.
[MASTER VOLUME]
slider :
