Processing Signals With Nrv10 Interfx; Applying The Expander-Gate - M-Audio NRV10 User Manual

interFX acts as an effect processing insert point for each channel of the NRV10 Mixer,
before all channels are summed to the stereo output of the NRV10 Mixer.
1.2.2

Processing Signals with NRV10 interFX:

As mentioned above, NRV10 interFX matches the channel configuration of the NRV10
Mixer, eliminating the need to configure the inputs and outputs of NRV10 interFX. For
example, if you have a microphone plugged into channel 1 of the NRV10 Mixer,
channel 1 of NRV10 interFX processes that microphone. NRV10 interFX offers an
Expander-Gate, followed by a Compressor, and then two custom effect slots on each
channel. Signals are processed in that order, and these "processors" are ordered from
top to bottom graphically, where the Expander-Gate is at the top of each channel, and
the second custom effect slot at the bottom. The User Guide of the NRV10 Mixer details
various signal connections, such as microphone and line inputs. Assuming that you've
followed the User Guide of the NRV10 Mixer, and have a microphone plugged into
channel 1 of the NRV10 Mixer, follow the directions below to process the signal of the
microphone:

1.2.2.1 Applying the Expander-Gate:

Note: While following this tutorial, if you perceive latency or a delay in the processed
signal, see Adjusting the Latency of the NRV10 Mixer.
An Expander-Gate is often used to reduce background noise, or "bleed" from other
instruments/sources. For example, if you apply the Expander-Gate to channel 1 (where
your microphone is attached), you can ensure that the channel outputs audio only
when you sing into the microphone, reducing the possibility of feedback, and
producing a cleaner signal. Once you have set a suitable level for the microphone
(directly on the NRV10 Mixer), follow these steps to apply the Expander-Gate of the
NRV10 interFX software's first channel to the microphone. The Expander-Gate is
located at the top of each NRV10 interFX channel:

Expander-Gate, the Expander-Gate mutes the signal.
