Test Function and Judgment criteria
Connect the level meter (with a JIS-C filter) to each terminal (PHONES, OUTPUT L/L+R, R, AUX OUT L, R).
Set the [MASTER VOLUME] at MAX and check the R channel output level. (1 kHz sine wave, PAN=R)
(PHONES L, R: 33 ohm load OUTPUT L/L+R, R: 10 kohm load
PHONES L: less than -30.0 dBm
OUTPUT L/L+R: less than -50.0 dBm OUTPUT R: +13.5 dBm +/- 2 dBm (PSR-1000), +11.6 dBm +/-2 dBm (PSR-2000)
AUX OUT L: less than -60.0 dBm AUX OUT R: +9.1 dBm +/- 2 dB (PSR-1000), +5.5 dBm +/- 2 dB (PSR-2000)
Connect the level meter (with a JIS-C filter) to each terminal (PHONES, OUTPUT L/L+R, R, AUX OUT L, R).
Set the [MASTER VOLUME] at MAX and check the L channel output level. (1 kHz sine wave, PAN=L)
(PHONES L, R: 33 ohm load OUTPUT L/L+R, R: 10 kohm load
PHONES L: +3.5 dBm +/- 2 dB
OUTPUT L/L+R: +13.5 dBm +/- 2 dBm (PSR-1000), +11.6 dBm +/- 2 dBm (PSR-2000) OUTPUT R: less than -50.0 dBm
AUX OUT L: +9.1 dBm +/- 2 dB (PSR-1000), +5.5 dBm +/- 2 dB (PSR-2000)
Check the sine wave output of EQ-Low frequency at about 65.4 Hz (C1). (PAN=Center)
Check the sine wave output of EQ-Mid frequency at about 523 Hz (C4). (PAN=Center)
Check the sine wave output EQ-High frequency at about 4186 Hz (C7). (PAN=Center)
Checks D/A converter noise.
Connect the level meter (with a JIS-C filter) to each terminal (PHONES, OUTPUT L/L+R, R, AUX OUT L, R) .
Set the [MASTER VOLUME] at MAX and check the noise level.
PHONES L, R: less than -75.0 dBm OUTPUT L/L+R, R: less than -70.0 dBm
Check the switches on the panel and LED.
Press the switches on the LCD as instructed. A pre-assigned note is output when the switch is pressed. (See table
1). When the switch with LED is pressed, that LED will light up. As the check result appears on the LCD when
all the switches are pressed as instructed. Check that OK is displayed. For the dial check, confirm that the
turning the data dial clockwise will increase the numerical value from 50 to 100 and turning it counterclockwise
will reduce it from 100 to 0.
Check that all panel LEDs are on. (Except for the [MIC. OVER] and [MIC. SIGNAL] LEDs of PSR-2000)
The 2-colors LED light up in orange.
Check that all red LEDs are on. (Except for the [MIC. OVER] LED of PSR-2000)
The 2-colors LED light up in red.
Check that all green LEDs are on. (Except for the [MIC. SIGNAL] LED of PSR-2000)
The 2-colors LED light up in green.
Check that all LCD dots are on.
Check that all LCD dots are off.
Press the [1] to [4] switches of [ONE TOUCH SETTING] in order. The brightness of the LCD grows lighter
every time a switch is pressed.
Connect the foot switch (FC-4) to the [FOOT PEDAL 1] jack.
Check that the C3 note is output when pressing the pedal, and that the C4 note is output when releasing the pedal .
Connect the foot volume (FC-7) to the [FOOT PEDAL 2] jack.
Check that the C3 note is output when fully pressing the pedal to the back (to maximum), and that the C4 note is
output when fully pressing the pedal to the front (to minimum).
Checks the pitch bend wheel.
First, it is checked that the [PITCH BEND] wheel is a center position.
Check that the C3 note is output when rotating the [PITCH BEND] wheel to minimum from center, and that the
C4 note is output when rotating it to maximum.
Checks the modulation wheel.
First, it is checked that the [MODULATION] wheel is a center position.
Check that the C3 note is output when rotating the [MODULATION] wheel to minimum from center, and that
the C4 note is output when rotating it to maximum.
After connecting the [MIDI IN] jack and [MIDI OUT] jack with a MIDI cable, execute the test. Set the [HOST
SELECT]switch to "MIDI".
Check that the C4 note is output and that the LCD displays "OK". If there is no input after one second since
signal output, it is judged NG.
Connect pin 3 to pin 5 and pin 6 to pin 8 of the [TO HOST] terminal, and execute the test.
Check that the following note sounds when changing the [HOST SELECT] switch position according to the
LCD indication; the LCD will display "OK". (PC1: note C3; PC2: note C4; MAC: note C5) If there is no input
after one second since signal output, it is judged NG.
Connect a microphone to the [MIC./LINE IN] jack and speak to it.
Set the [MIC./LINE] select switch to [MIC.] and set the [INPUT VOLUME] at maximum.
Check the voice sound by hearing that there is not unusual noise or abnormal sound.
