Oscillator
fig.TB-OSCFlow.eps
Oscillator is a function that generates a pink noise, white noise, or sine wave, and sends it to an AUX, MTX, MAIN L/R, or the output
patchbay. This is useful when you need to measure the acoustical response of a hall, or when checking the connections of external devices.

At the SETUP screen, select “OSCILLATOR“ and press
[ENTER].
The OSCILLATOR screen is displayed.
Meter display
These indicates the level of talkback/oscillator and of AUX,
MTX, and MAIN.
Symbols are displayed for the output destination for

Talkback and the oscillator share the same output destination.
Output destination
This shows the destination for oscillator.
ON/OFF button
This button turns the oscillator on/off.
You can assign oscillator on/off to a USER button.
FREQ
This adjusts the sine-wave frequency in a range of 20 Hz to
20 kHz.
LEVEL
This adjusts the output level of the oscillator in a range of -Inf
dB to 0.0 dB.
1.
Access the OSCILLATOR screen.
2.
