1Getting Started
Welcome to the NRV10 interFX User Guide. The NRV10 interFX software is an audio
processing application designed specifically for the NRV10 Mixer, greatly expanding its
audio processing capabilities. Typically, you will use NRV10 interFX in a live situation,
when you want to add more effect processing to microphones and/or other audio
sources plugged into the NRV10 Mixer. The channel configuration of NRV10 interFX is
identical to the NRV10 Mixer, providing four mono channels and two stereo channels.
Due to this configuration, there is no need to configure the inputs and outputs of NRV10
interFX. After launching the software, simply use the per-channel Expander-Gate and
Compressor, and choose up to two user-definable VST effects per channel.
1.1 Check for the Latest Update
To ensure that you have the most recent version of NRV10 interFX, choose “Check for
Updates”from the Options Menu of the NRV10 interFX software (press the Options
Button ). This action opens the NRV10 interFX update page of the Audiffex website.
Before downloading and installing the update, press the Options Button , choose
“Help,”and then “About.”Compare the version number reported by the About Dialog
with the version number listed on the Audiffex website. If the version numbers match,
you do not need to update NRV10 interFX.
1.2 A Tutorial on Working with the NRV10 interFX
Software:
Below is a tutorial that describes the typical workflow of NRV10 interFX. This tutorial
assumes that the driver of the NRV10 Mixer is installed, and that the NRV10 Mixer is
connected to your computer:
1.2.1 Preparing the NRV10 Mixer for Use with NRV10
interFX:
To use the NRV10 Mixer with NRV10 interFX, ensure that the Pre EQ/Post EQ
button of the NRV10 Mixer is pushed out/up before launching NRV10 interFX. If this
button is pushed in/down when using NRV10 interFX, you will experience feedback. In
addition, ensure that the CH/FW buttons at the top of each channel of the NRV10 Mixer
are pushed in/down. This sends the signal from each channel of the NRV10 Mixer to
the associated channel of the NRV10 interFX software. NRV10 interFX then outputs the
processed signals to the related channels of the NRV10 Mixer. In this way, NRV10

5
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:
1. By default, NRV10 interFX disables all Expander-Gates. To enable the Expander-Gate
on channel 1, click the Expander-Gate Bypass Button of channel 1. When the Expander-
Gate is not bypassed, the
Expander-Gate Bypass Button does not display a red LED.
2. Move the
Expander-Gate Ratio Control of channel 1 fully clockwise.
3. Move the Expander-Gate Threshold Control of channel 1 fully counterclockwise.
4. As you sing or play an instrument into the microphone, slowly move the
Expander-
Gate Threshold Control
of channel 1 clockwise. At some position (depending on how
loudly you are singing or playing), this movement causes your microphone signal to
"mute." Whenever the microphone signal falls below the threshold setting of the
Expander-Gate, the Expander-Gate mutes the signal.

6
5. If you wish to reduce the volume of the signal, rather than mute it when the
microphone signal falls below the threshold setting, move the Expander-Gate Ratio
Control
of channel 1 counterclockwise, until you achieve the desired result. This
process is commonly referred to as "downward expansion."
6. By adjusting the
Expander-Gate Attack Control , you can adjust how fast the signal
reduces to the setting of the Expander-Gate Ratio Control , after the signal falls below
the threshold setting of the Expander-Gate. The fully counterclockwise position yields
the fastest "attack," and the fully clockwise position yields the slowest "attack."
7. By adjusting the Expander-Gate Release Control , you can adjust how fast the signal
"un-mutes," or increases from the setting of the
Expander-Gate Ratio Control , after the
signal exceeds the threshold setting of the Expander-Gate. The fully counterclockwise
position yields the fastest "release," and the fully clockwise position yields the slowest
"release."
1.2.2.2Applying the Compressor:
A Compressor reduces the dynamic range of an audio signal (the difference between
the loudest and softest sound produced). For example, a song might include relatively
quiet vocals in the verse, with significantly louder vocals in the chorus. The Compressor
can help compensate for the difference in loudness between the two song sections.
Once you have set a proper input level for the microphone (directly on the NRV10
Mixer), follow these steps to apply the Compressor of the NRV10 interFX software's first
channel to the microphone signal. The Compressor is located below the Expander-
Gate of each NRV10 interFX channel, and is labeled "Comp":
1. By default, NRV10 interFX disables all Compressors. To enable the Compressor on
channel 1, click the Compressor Bypass Button of channel 1. When the Compressor is
not bypassed, the
Compressor Bypass Button does not display a red LED.
2. Move the Compressor Ratio Control of channel 1 to approximately 9 o'clock.
3. Move the Compressor Threshold Control of channel 1 fully clockwise.
4. As you sing or play an instrument into the microphone, slowly move the Compressor
Threshold Control of channel 1 counterclockwise. At some position (depending on how
loudly you are singing or playing), this movement causes your microphone signal to
reduce in volume. Whenever the microphone signal exceeds the threshold setting of
the Compressor, the Compressor reduces the volume of the signal.
5. The Compressor Ratio Control determines exactly how much the Compressor
reduces the signal, once the signal exceeds the threshold setting of the Compressor.
The fully counterclockwise position yields minimum compression, while the fully
clockwise position yields maximum compression, or "limiting."

7
6. By adjusting the Compressor Attack Control , you can adjust how fast the signal
compresses (reduces to the setting of the Compressor Ratio Control) after the signal
exceeds the threshold setting of the Compressor. The fully counterclockwise position
yields the fastest "attack," and the fully clockwise position yields the slowest "attack."
7. By adjusting the Compressor Release Control , you can adjust how fast the signal
increases from the setting of the Compressor Ratio Control, after the signal falls below
the threshold setting of the Compressor. The fully counterclockwise position yields the
fastest "release," and the fully clockwise position yields the slowest "release."
1.2.2.3Working with Custom Effects:
Each channel of NRV10 interFX allows you to load up to two custom, or user-defined,
VST effects. The User Effect Slots are located beneath the Compressor of each channel.
Both User Effect Slots function in the same manner, so we'll cover only the first
User Effect Slot in this tutorial. To load a VST effect to User Effect 1 , follow these steps:
1. Click the
User Effect 1 Plug-in Chooser of channel 1, and select the desired plug-in.
2. To open the editor window of the effect, click the User Effect 1 Edit Button .
3. To bypass User Effect 1 , click the User Effect 1 Bypass Button .
4. To remove the effect, click the User Effect 1 Plug-in Chooser , and select "Remove
Plug-in" from the resultant menu.
Note: If NRV10 interFX does not show plug-ins that you known are installed on your
system, refer to the Troubleshooting section of this guide.
1.2.2.4Setting Optimal Output Gain:
Located at the bottom of each NRV10 interFX channel, you'll find a Gain Control and a
Level Meter . The Gain Control raises or lowers the output of the NRV10 interFX channel
to the NRV10 Mixer, where the 12 o'clock position equals no gain change. Depending
on the Expander-Gate, Compressor, and custom effect settings of a channel, you may
need to alter the Gain Control . While adjusting the Gain Control , observe the
Level Meter . If the uppermost LED lights up (the red LED), move the Gain Control
counterclockwise to reduce the signal's loudness, and thus prevent distortion. It is also
good practice to "boost" the signal as much as possible, without creating distortion. To
increase or "boost" the loudness of the signal, move the Gain Control clockwise.

8
1.2.2.5Processing Additional Channels:
The instructions above apply to all channels of NRV10 interFX. When selecting your
input sources (microphones, turn-tables, etc) for the NRV10 Mixer, keep in mind that
channels 1 through 4 are mono channels, and channels 5/6 and 7/8 are stereo
channels .
1.2.3 Storing a Program:
A Program contains all channel settings of NRV10 interFX. Using Programs , you can
quickly store and recall NRV10 interFX settings. For example, in a live setting, you can
create Programs tailored to specific songs and instruments. To save all channel
settings of NRV10 interFX to a
Program , follow these steps:
1. Click the
Store Button , located at the top of the NRV10 interFX user interface.
2. After clicking the store button, additional controls appear at the top of the NRV10
interFX user interface, as pictured in the graphic below:
.
3. Use the up/down arrows to select the desired Program Number . There are 128
Program Numbers available.
4. Type the desired Program name into the name field.
5. Click the OK Button .
6. If a Program exists in the chosen Program Number , clicking the OK Button will
overwrite that Program .
If you wish to cancel the store operation, click the Cancel Button .
1.2.4 Loading a Program:
To load a Program , follow these steps:
1. Press the Select Button , located at the top of the NRV10 interFX user interface.
2. Click the desired
Program from the resultant list.
1.2.5 Adjusting the Latency of the NRV10 Mixer:
As NRV10 interFX was designed primarily for live settings, it is vitally important to use
the lowest possible latency setting allowed by your computer. Latency is a measure of
the delay between the time that sound enters the NRV10 Mixer, travels through NRV10
interFX, and feeds back to the NRV10 Mixer. Depending on the processing power of
your computer, you may hear clicks or pops if the latency setting of the NRV10 Mixer is
too low. If you hear clicks or pops, raise the latency setting incrementally until you
achieve "glitch-free" audio playback.

9
To adjust the latency setting of the NRV10 Mixer, follow these steps:
1. Click the Options Button of NRV10 interFX.
2. From the resultant menu, choose "Preferences."
3. In the
Preferences Dialog , click the Audio Tab .
4. Click the Control Panel Button of the
Preferences Dialog . This action opens the
NRV10 Control Panel.
5. Click the Hardware Tab of the NRV10 Control Panel.
6. Using the control labeled "ASIO/WDM Buffer Size," select the desired buffer size,
and close the NRV10 Control Panel.
7. Click the Close Button of the Preferences Dialog .
1.2.6 Using NRV10 interFX with other Applications:
On Mac OS X, multiple applications can share the same driver, so you can run other
applications through the NRV10 Mixer alongside NRV10 interFX. On Windows XP, when
using ASIO (which is the driver that provides the best latency times, and the only driver
supported by NRV10 interFX), only one application may access the driver at a time. If
you wish to use ReWire client applications, such as Torq or Live with the NRV10 Mixer
and NRV10 interFX, you can upgrade to NRV10 interFX Pro. When you exit NRV10
interFX, a dialog provides upgrade instructions. NRV10 interFX Pro includes the
following enhancements:
•ReWire Player: Host ReWire applications such as Torq and Live directly in NRV10 interFX
Pro, with complete control over the output channel.
•Track Player: Play back playlists of audio files (Wav, MP3, AIF) through NRV10 interFX
Pro, with complete control over the output channel.
•6 User Effect Slots.
•Additional VST Plug-ins.
•Recorder: Record the master output of the NRV10 Mixer.
•Advanced MIDI Mapping of effect parameters, NRV10 interFX Pro channels, and Program
changes.
•Support for VST Instruments: Add VST Instruments to NRV10 interFX channels, and mix
them with the incoming audio signal.
