1 Getting 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 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 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.
"mute." Whenever the microphone signal falls below the threshold setting of the Expander-Gate, the Expander-Gate mutes the signal. 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.
The fully counterclockwise position yields minimum compression, while the fully clockwise position yields maximum compression, or "limiting." 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.
1.2.1.5 Processing 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 . Storing a Program: A Program contains all channel settings of NRV10 interFX. Using Programs, you can quickly store and recall NRV10 interFX settings.
too low. If you hear clicks or pops, raise the latency setting incrementally until you achieve "glitch-free" audio playback. To adjust the latency setting of the NRV10 Mixer, do the following: 1. 2. 3. 4. 5. Click the Options Button of NRV10 interFX. From the resultant menu, choose "Preferences." In the Preferences Dialog, click the Audio Tab. Using the Buffer Size Selector, select the desired buffer size. Click the Close Button of the Preferences Dialog.
2 NRV10 interFX User Interface Overview The channel configuration of NRV10 interFX is identical to the NRV10 Mixer, providing four mono channels and two stereo channels. Each channel of NRV10 interFX includes an integrated Gate, Compressor, and two User Effect Slots. Below is an image of the NRV10 interFX user interface. Refer to the table below the graphic for details of each control.

3 Included Effects NRV10 interFX includes six VST effects. Two of these effects, Compressor and Expander-Gate, are included as separate plug-ins, but are functionally identical to the integrated Compressor and Expander-Gate. 3.1 Common Effect Controls The following controls are common to all included NRV10 interFX effects. Below is an image of these controls. Refer to the table below the graphic for details of each control.

7 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.
8 NRV10 Mixer-NRV10 interFX Signal Flow Diagram The block diagram below illustrates the basic signal flow of an NRV10 Mixer channel, and the point at which audio sends to and returns from the NRV10 interFX software. For a complete signal flow diagram of the NRV10 Mixer, refer to the printed getting started guide.
9 Keyboard Shortcuts To aid in learning the NRV10 interFX software, the application displays tool-tips. When hovering the mouse over a control, NRV10 interFX displays tool-tips that provide the name of the control. By holding the Command key and mousing over a control, NRV10 interFX displays a detailed description of the control.
NRV10 interFX Help: Command+? NRV10 interFX lists keyboard shortcuts directly to the right of each menu bar item, using symbols for Command, Option, and Shift.
10 Troubleshooting 10.1 Loud Feedback Heard After Launching 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. 10.2 Noticeable Delay Between Input to the NRV10 Mixer, and Output from NRV10 interFX: The cause of this issue is a high latency setting, and the remedy is to lower this setting.
10.5 The Volume Fader and Pan Knobs of the NRV10 Mixer Do Not affect NRV10 interFX: This behavior is normal. The signal of an NRV10 Mixer Channel flows to NRV10 interFX, and back to the NRV10 Mixer, before it travels through the Volume Fader and Pan Knob of an NRV10 Mixer Channel. See NRV10 Mixer-NRV10 interFX Signal Flow Diagram for more details. 10.6 NRV10 interFX Crashes on Startup: On startup, NRV interFX can bypass corrupted Programs and settings caused by, for example, a computer power failure.
