The Mackie ProFXv3 series mixers includes a new GigFX effects engine that instantly delivers your choice of 24 effects. In addition, the ProFX6v3 also features smooth rotary Level controls for each channel strip and 2-band equalization for channels 1&2. The mixer's "Built-Like-A-Tank" design features a solid steel chassis with rugged ABS side panels. The Mackie mixer also includes Waveform OEM professional software and plugin package (via free download).

Applications: The Mackie ProFX6v3 is great for Live sound mixing, houses of worship, clubs, gyms, banquet halls, conference and board rooms, studio and field recording, video post-production, multimedia applications, broadcast, and many more.

Channel Strips

Main Inputs: The ProFX6v3 offers the following main inputs:

• Onyx Mic Preamps (Ch. 1&2): Mackie's Onyx microphone preamps offer up to 60dB of gain and ultra-low noise performance. Channels 1&2 are equipped with female XLR/1/4" combo jacks accepting balanced mic or line level inputs from almost any type of source. The mic inputs feature 48-volt phantom power from a single 2-way switch.
• Stereo Line Inputs (Ch. 3/4): Channels 3/4 consist of a stereo pair of 1/4" TRS jacks, each accepting line level signals from balanced or unbalanced sources.
• Line/Hi-Z Input (Ch. 1&2): Channels 1&2 feature a Line/Hi-Z switch that allows you to connect a guitar to either 1/4" input without a DI box. With the switch pressed in, the input impedance is optimized for a direct connection. In the out position, that corresponding 1/4" input becomes a line input. 
• 1/8" Stereo (Ch. 5/6): This uses a single 1/8" stereo input for use with a portable player, smartphone, or tablet.
• USB: A front-panel USB 3-4 switch on channel strip 5/6 lets you override the 1/8" audio input with the rear-panel USB input, letting you mix audio from a computer.

Gain: Input channels 1&2 have a Gain control that lets you adjust the input sensitivity. The Gain controls feature a "U" symbol to indicate "Unity Gain," or no change in the signal level. Level Set LEDs are provided to let you know if any of the channels are distorting.

• Line Inputs: For line-level signals, you can adjust the input sensitivity between -20dB and +40dB.
• Mic Inputs: For mic signals (from the XLR connectors), the range of adjustment is 0dB to +60dB.

 Low Cut: A Low Cut switch on channels 1&2 cuts bass frequencies below 100 Hz at a slope of 18dB per octave.

2-Band Equalization: Inputs 1&2 have 2-band equalization, with "low shelving" at 80Hz and "high shelving" at 12kHz. Shelving means the circuitry boosts or cuts all frequencies past the specified frequency. Each control can provide 15dB of boost or cut at 80Hz and 12kHz. The "U" symbol indicates the center position (Unity Gain) where there is no change in the signal level.

FX Switches: The ProFX6v3 features an FX On/Off switch for channel strips 1&2. With the switch On, the channel signal is assigned to the FX send, post-channel Level dial. All effected channel signals are added to the main mix by increasing the level of the "FX to Main" dial.

Stereo Pan Switch: A single switch for Channels 1&2 determine the stereo placement of each. When the switch is out, each mono channel feeds both the right and left sides of the main mix equally. When pressed in, Channel 1 will play through the left side and Channel 2 will play through the right.

Level Controls: The ProFX6v3 features a rotary Level control for Channels 1, 2, and 3/4. Each control includes "U" (unity), for no change in the signal, and can provide up to 10dB of additional signal gain if needed. Input level for Channel 5/6 (1/8" stereo input) is determined by the playback source.

Outputs & Additional Controls

Outputs:

• Main: Two balanced XLR and two balanced/unbalanced 1/4" jacks are provided for the Main Output signal. Both outputs are adjusted by the Main fader and provide a line-level signal for running to an outboard amplifier or powered speakers.
• Phones: A 1/4" TRS headphone output is provided with a corresponding rotary Phones dial for adjusting the output.

Main Output Level: A single rotary control adjusts the output level of the main mix signals sent to the XLR and 1/4" Main output jacks. A corresponding Break button, with LED indicator, can be used to quickly mute all signals going to the Main, Control Room, and Headphone outputs.

• Main Meters: A pair of 8-segment LEDs display the Main Output level, ranging from -24 to 14. LEDs from -24 to 8 light green, while LED 14 lights yellow, indicating the signal level is near clipping. Red "OL" clip LEDs will light if the signal starts to clip.

Additional Controls

• Blend: A rotary knob adjusts the amount of blended signal from all Input Channels and the USB 1-2 return input. Fully left provides just the Input Channel signal, center provides a 50/50 blend, and fully right provides just the USB 1-2 signals. This lets you blend between monitoring your computer's output and the feed from the mixer, with zero latency. A corresponding To Phones button allows the blended signal to be sent to the Headphone output.
• 48V: Activates +48V of phantom power to all of the XLR input jacks. A corresponding red LED lights when activated.

Built-In FX

GigFX: The Mackie ProFX6v3 includes 24 high-quality FX (effects) built-in for easy selection and use. A Preset rotary knob with corresponding LED display let you quickly cycle through each Preset, while pressing the rotary knob selects the Preset number that's displayed. A list of all FX Presets are silk-screened on the front panel, along with an Effects Mute switch for quickly muting the selected FX. A corresponding LED lights when the switch is in use. An optional footswitch can be used to quickly mute/un-mute the selected FX. Effects include the following:

Connectivity

USB: A rear-panel USB type-B (2.0) is provided for connection to a computer DAW (Digital Audio Workstation), providing a 2x4 I/O, along with 24-Bit/192kHz recording resolution. The 2x4 USB I/O lets you record a stereo signal to the computer and return up to 2 stereo playback streams from the computer. This lets you monitor specific tracks during playback in addition to the full mix.
