9.14 SigGen

The Signal Generator provides a test signal to help you align and test components of a sound system.

Assign – Click a Mix button to assign the SigGen. The signal routes through the Mix processing, therefore

will be affected by the Mix EQ and compressor.

 The SigGen is disabled while Talkback is active.

Settings – The SigGen Level can be set from fully off to full scale +18dB. Click the Mute button to turn off.

There are 4 types of signal available:

Sine - A pure tone. Set the frequency using the Frequency box. This can be swept across the full audio

spectrum from 20Hz to 20kHz.

White Noise - A signal containing all audio frequencies with equal energy per Hz.

Pink Noise - A signal containing all audio frequencies with equal energy per octave, a logarithmic curve and

typically used for testing speakers and room response.

Band Pass Noise - Band filtered pink noise centred around the frequency set using the Frequency control.
