■ TEST■PROGRAM
1.■ Measurement■con dition
1-1.■ Environment
Perform testing under following conditions.
Ordinary temperature (5°C to 40°C)
Ordinary humidity (20% to 90%)
If the test results deviate from the test standard range, however, re-test 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-5D, PA-150, PA-150A or 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.
0 dBu = 0.775 Vrms
• Level meter (using JIS-C filter)
• Frequency counter (should be capable of measuring to three places of decimals)
• Oscilloscope
1-4.■ Test■jig
Following jigs are required for testing.
• USB cable (A-B type)
• USB flash memory
• Foot switch (FC3A/FC4A/FC5)
• Pedal unit (LP-5A/LP-5AWH)
1-5.■ Terminal■condition
Unless otherwise specified, take measurement at the PHONES terminal. (Use a stereo plug.)
PHONES : Install a measuring plug (L/R ch: 33-ohms load)
Install a measuring plug to one side only. (P-115B/P-115WH)
AUX OUT : Install a measuring plug (L/R ch: 10k-ohms load)
PEDAL UNIT : Connect the pedal unit (LP-5A/LP-5AWH).
SUSTAIN : Connect the foot switch (FC3A/FC4A/FC5)
Connect the pedal unit and foot switch before turning on the power.
1-6.■ Control■condition
Unless otherwise specified, set control knobs as follows.
MASTER VOLUME : Max
PEDAL : Off
Set others in the default state when the power is turned on.
