Function and judgment criteria
Checks the R channel output.
Connect the level meter (with a JIS-C filter) to each output terminal.
Set the [MASTER VOLUME] at the MAX. position and check the output level of the R channel.
(1kHz sine wave, PAN = R)
PHONES L: -40.0dBm or less
AUX OUT L/L+R: -50dBm or less
AUX OUT (LEVEL FIXED)L: -50dBm or less
Checks the L channel output.
Connect the level meter (with a JIS-C filter) to each terminal.
Set the [MASTER VOLUME] at the MAX. position and check the output level of the L channel.
(1kHz sine wave, PAN = R)
PHONES L: +2.0dBm ± 2dB
AUX OUT L/L+R: -1.5dBm ± 2dB
AUX OUT (LEVEL FIXED)L: -2.0dBm ± 2dB
Checks the EQ-LOW frequency.
Check that 65.4Hz (C1) sine wave is output. (PAN = Center)
Checks the EQ-MID frequency.
Check that 523Hz (C4) sine wave is output. (PAN = Center)
Checks the EQ-HIGH frequency.
Check that 4186Hz (C7) sine wave is output. (PAN = Center)
This test item is included in the factory inspection.
Checks the switches on the panel and LED.
Press the switches as their names are indicated on the LCD. When each switch is pressed, its pre-
assigned note is output. (See Table 1 on p. 41.) When the switch with LED is pressed, that LED will
light up at the same time. Upon completion of checking all switches, "SW. LED Chk OK" is displayed
on the LED display.
Check that all LEDs light up.
Check that all red LEDs light up.
Check that all green LEDs light up.
Check that all LCD dots light up.
Check that all LCD dots go off.
Checks the soft pedal.
Check that the C3 note is output when the test is executed and the soft pedal is depressed and the C4
note is output when it is released. For the check result, check that "Soft Test OK" is displayed on the
LCD display.
Checks the sostenute pedal.
Check that the C3 note is output when the test is executed and the sostenute pedal is depressed and
the C4 note is output when it is released. For the check result, check that "Sostenute Test OK" is
displayed on the LCD display.
Checks the damper pedal.
Check that the C3 note is output when the damper pedal is depressed and the C4 note is output when
it is released. For the check result, check that "Damper Test OK" is displayed on the LCD display.
Connect the foot volume (FC-7) to the [AUX PEDAL] jack.
Check that the C3 note is output when the pedal is depressed fully to the back (DOWN) and the C4
note is output when it is depressed fully to the front (UP). For the check result, check that "Aux Pedal
OK" is displayed on the LCD display.
