Oscillator - Yamaha CS1D Operating Manual

CS1D Operating Manual (Basic Operation)

Oscillator

The PM1D provides an internal oscillator for test purposes, and can send a sine wave or pink noise to the desired bus.
This can be used to check the operation of devices connected to an output unit, or to check the acoustical characteristics
of a concert location.
[Procedure]
1. In the LCD FUNCTION ACCESS block, press the
[MON/CUE] switch several times to access the fol-
lowing OSCILLATOR screen (MON/CUE func-
tion).
In the OSCILLATOR screen you can select the out-
put waveform of the oscillator, and select the output
destination of the signal.

2. In the PINK/BURST section of the OSCILLATOR
screen, use the PINK NOISE button and BURST
NOISE button to select the type of signal that the
oscillator will output.
If this button is on, repeated bursts of pink noise will be
sent to the specified bus or output jack. You can use
the on-screen knobs to adjust the duration (WIDTH) of
the noise itself and the spacing of the silent portions
(INTERVAL).
If this button is on, pink noise will be sent to the speci-
fied bus or output jack.
If both the PINK NOISE and BURST NOISE buttons
are off, a sine wave will be sent to the specified bus or
output jack. Use the SINE WAVE FREQ section to
specify the frequency of the sine wave.
Specify the spacing This HPF/LPF can be used to process
of the silent inter- the noise when either the PINK NOISE
vals when the or BURST NOISE buttons are on.

above to adjust the cutoff frequency.
Specify the duration of the noise itself when the
BURST NOISE button is on.
3. If you selected sine wave in step 2, use the SINE
WAVE FREQ section to specify the frequency of the
sine wave.
This knob continuously adjusts the
frequency of the sine wave.
These buttons set the sine wave to
preset frequency values (10 kHz/
1 kHz/100 Hz).
4. Use the LEVEL knob in the OSC section of the
OSCILLATOR screen to set the output level of the
oscillator.
