Oscillator and Talkback Section Oscillator and Talkback Section The oscillator and talkback sections, located to the right of the master section, are independent. The oscillator section is capable of generating pink noise or sine-wave signals for testing and system setup via the TB bus, while the talkback section can be used to send the audio signal from the talkback mic via the TB bus. The [TB/OSC] switches provided on each master and matrix bus allow the talback/oscillator signal to be routed as required. [OSC ON] Switch [TB/OSC OUT] Switch Talkback [ON] Switch The oscillator and talkback signals are applied to the TB bus by engaging the [OSC ON] or talkback [ON] switch, respectively. Since the oscillator and talkback sections share the same TB bus, however, only one can be engaged at a time. If both the [OSC ON] and talkback [ON] switches are engaged simultaneously, the talkback section takes priority. The talkback and oscillator signals can be sent to the rear-panel TB/OSC OUT connector by engaging the [TB/OSC OUT] switch. 38

Oscillator and Talkback Section
38
The oscillator and talkback sections, located to the right of the master section, are independent. The
oscillator section is capable of generating pink noise or sine-wave signals for testing and system setup via
the TB bus, while the talkback section can be used to send the audio signal from the talkback mic via the
TB bus. The [TB/OSC] switches provided on each master and matrix bus allow the talback/oscillator
signal to be routed as required.
The oscillator and talkback signals are applied to the TB bus by engaging the [OSC ON] or talkback [ON]
switch, respectively. Since the oscillator and talkback sections share the same TB bus, however, only one
can be engaged at a time. If both the [OSC ON] and talkback [ON] switches are engaged simultaneously,
the talkback section takes priority. The talkback and oscillator signals can be sent to the rear-panel
TB/OSC OUT connector by engaging the [TB/OSC OUT] switch.
