8.2 Audio Setup - Talkback
Set up and assign Talkback to talk to the musicians via
their monitors, or make announcements via the house
(PA) mix:
HPF – Dial in the High Pass Filter to remove low
frequency pops and resonance while talking. Factory
default is 120Hz.
48V – Hold for 1 second to switch on phantom power.
Gain – Adjust the talkback mic level.
Assign – Touch to toggle the assignments to the
different mixes on or off.
Press the surface Talk key to talk to the musicians or
house. Active Talk is indicated by the green
[T] icon in
the lower toolbar.
Momentary Latch option - Press the Fn key to open
the Options screen to access the Talk option:
Option Off = The Talk key is momentary action only.
Press and hold to talk.
Option On = The Talk key latches on or off when you
press it quickly. It becomes momentary when you
press and hold it for longer than 0.5 second.
Select this option when you are working with a
switched talkback microphone and therefore want Talk
to be permanently selected.
8.3 Audio Setup –Signal Generator
Set up and assign the Signal Generator to test
loudspeakers and align levels between equipment.
Source – Touch to open the list of sources available:

Sine – Pure tone with adjustable frequency. Set to
1kHz and use meters to match equipment levels.

White Noise – Equal energy per Hz.

Pink Noise – Filtered white noise for equal energy
per octave. This is a good source to use for
testing loudspeaker drivers and phase. Its
response matches the way we hear frequencies.

Band-pass Noise – Pink noise filtered around a
frequency which can be swept from low to high.
Level – Start with the level set low to avoid unexpected
loud sounds when you assign to the mixes.
Mute – Turns the signal off.
Assign – Touch to toggle the assignments to the LR
and Mixes 1-10 on or off. Assignment to the Groups
and Matrix is not available on the Qu-16.
Note – To avoid noise in the system remember to turn
the assignments off when you have finished using the
generator.
