Yamaha O2R Manual Do Utilizador

Digital I/O, Setup, and Utilities

Before starting a recording session, many engineers like to record a few 
seconds of sine wave tones. These tones are used to compare the 
performance of multitrack recorders when you take the master tapes from 
one studio to another. This is especially important when the multitrack 
recorder is analog. The 02R has an oscillator function that allows you to 
send 100 Hz, 1 kHz, and 10 kHz sine waves and white noise to the 
auxiliary and output buses and the stereo bus.

Shown below is the UTILITY 1/4 page—Oscillator.

•

—This icon is used to turn the oscillator on or off. When the 

oscillator is on, the Control Room DIM (mute) function is automatically 
turned on.

•

—This rotary icon allows you to set the oscillator output level. Set 

the level from –96 dB to 0 dB. Watch the level meters to ensure you are 
not driving the 02R into digital clipping.

•

—These icons allow you to select the wave form you want 

output. The 02R can generate four different wave forms: “Sine 100Hz”, 
“Sine 1kHz”, “Sine 10kHz”, and “Noise”.

•

—Select the output buses 1 through 8.

•

—Select the stereo bus.

•

—Select the auxiliary buses 1 through 8.
