determined by Hold, down curve is determined by Release. Parameter Adjustment:
To adjust the parameter of Gate by dragging the slider, or turning the main
Encoder on the control panel (fine tuning can be activated when pressed the
knob down). Double press the parameter frame to set it as default. Threshold:
Adjust the threshold of noise gate on the channel, ranges from -80 dB to 0 dB
with default @ -80dB. Any signal lower than Threshold will be cut off, as a
result, the level of the signal has to surpass the threshold in order to get
through the noise gate. Hold (time of hold): from 2 ms up to 2000 ms with
default @ 2 ms. Attack (time of start): from 0.5 ms to 100 ms with default @ 3
ms. Release (time of release): from 2 ms to 2 s with default @350 ms
(compatible with many kinds of sound source) Depth: adjust attenuation of
signals lower than the Threshold, ranges from 0 dB to -80 dB with default @-80

Adjustment: To adjust the parameter of Gate by dragging the slider, or turning
the main Encoder on the control panel (fine tuning can be activated when
pressed the knob down). Threshold: Adjust the Threshold of the compressor on
the channel ranges from -80 dB to 0 dB with default @ -20 dB. Any signal lower

higher than Threshold to a certain extent. Ratio: Adjust compression ratio,
from 1.0 to 20.0 with default @1.0. Attack: from 0.5 ms to 100 ms with default
@25 ms. Release: from 20 ms to 5 s with default @350 ms (compatible with many
kinds of sound source) Gain: To compensate the compression, from -12 dB to +12

Set up your microphone at least several meters away from the speakers to pick
up their full range. Ideally put it in the center position of the audience.
Turn up the master fader sending pink noise to your system until your
microphone clearly picks up the audio on the level meter of your microphone
channel. Please make sure there is no EQ or any other effects in neither the
microphone channel and bus used for measurement, nor the LR output at this
time.
Enter the effects section in the Setup dialog and choose either GEQ1 or GEQ2
and turn on the RTA. Note that there are two modes normal (below) and
difference that will more clearly show small changes. Which mode you use does
not matter here.

Go to the Patch page in the setup dialog. Choose one of the Custom settings and change the routing of USB L and USB R to your chosen stereo bus.
Bus Send Sub-page The input channel can send signal into 4-channel mono bus, 4-channel stereo bus and L/R master output bus.
2 3 4 5
Now everything you microphone detects can be seen in the RTA on the GEQ page.
If you choose to use an external pink noise source the next part can be
skipped. Otherwise please turn on the oscillator found in the Monitor section
and set it to send to L/R MIX OUTPUT. Use either pink noise or sine sweep
mode, here pink noise was used. Take care when using sine sweep though, as it
is more susceptible to room resonances and may not lead to useful results in
small or resonant rooms.
Channel Switch Single press the key to switch between previous or next channel
on the same layer
Bus-send enable Single press a bus button, to send signal to this bus, press
again to disable the send.
PreFader/PostFader Switch The default is set as PreFader, single press the key
to switch to PostFader, press again to set it back to default.
PAN control he default is set as 50|50, the PAN value can be tuned by dragging
the slider, or turning the main Encoder on the control pane. Double press the
parameter frame to set it back to default.
Send level control Control the level of signal by drag the slider up and down.
Set up your microphone at least several meters away from the speakers to pick up their full range. Ideally put it in the center position of the audience. Turn up the master fader sending pink noise to your system until your microphone clearly picks up the audio on the level meter of your microphone channel.
You may store the measurement like any other library for later use, but note that the response of a room
can significantly change with the audience and also the setup of the PA system. Thus you will usually
want to do a measurement with the exact PA and speaker setup as during the show.

RTA Usage
With the RTA measure function your device can detect the frequency response of
the room and try to correct it automatically. You can either use the internal
oscillator of the device, or an external pink noise source. You also need a
high-quality measurement microphone; this should be connected to one of the 12
MIC input channels. Measurement microphones generally need phantom power, so
make sure to turn on the 48V in the input section of your selected channel
(here CH1) and turn up the gain until you get a proper signal.
