Pink Noise
On/Off – Turns Pink Noise on or off.
1/3 Octave Eq
. On/Off – Turns 1/3 octave equalization on or off. This affects all
channels.
Input
LineIn/LineOut/Mic – LineIn means that the signal source for the RTA is from the
current input channel and does not have any processing (Dirac, EQ, etc). LineOut
means that the signal source for the RTA is from the current output channel, so you
would see the effects of the Dirac, EQ, etc. If you are using the internal RTA to check
the room tune, then you would select Mic.
Note
: When the Input field is
LineIn
, the RTA selects the input channel. The controls for EQ,
bass, treble, and trim represent what is applied to input channel and their effects will not show
up on the RTA display.
When the Input field is
LineOut
the RTA displays the output channel. Channel tuning should
not be modified while the RTA input is in Line Out, but LineOut can be used to monitor the
effect of the EQ settings currently applied.
When the input field is set to Mic, the RTA selects the Mic input which will show the effects
of the EQ settings as well as the room. Channel tuning should be done in this input or with an
external RTA.
