Channel Strips

Main Inputs: The ProFX10v3 offers the following main inputs:

• Onyx Mic Preamps (Ch. 1-4): 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 while channels 3&4 feature standard female XLR sockets, all 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.
• Mono Line Inputs (Ch. 1-4): Channels 1&2 have the aforementioned combo jacks while Channels 3&4 have 1/4" 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.
• Stereo Line Inputs (Ch. 5/6&7/8): These 2 stereo Channels feature pairs of 1/4" jacks that can accept stereo or mono balanced or unbalanced sources. They may be used with just about any professional or semi-pro instrument, effect, or tape player. If you are connecting a mono source, you should use the left (mono) input, and the mono signals will appear on both sides of the main mix. The Gain for each pair of stereo line inputs is adjusted with a single potentiometer.
• 1/8" Stereo (Ch. 9/10): 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 9/10 lets you override the 1/8" audio input with the rear-panel USB input, letting you mix audio from a computer. This signal can be EQ'd, sent to Aux outputs, and is routable to the Mains or Subgroups.
• Inserts: Channels 1, 2, 3, and 4, feature a single 1/4" TRS insert jack for connecting serial effects processors, such as compressors, equalizers, de-essers, or filters. The signal can go out of the insert jack to the external device, be processed, and return on the same insert jack. (The insert cable must be wired as follows: Tip=Send, Ring=Return, Sleeve=Common Ground.)

Gain: Input channels 1-4 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 1-4 cuts bass frequencies below 100 Hz at a slope of 18dB per octave.

Compression: Input Channels 1&2 feature built-in compression that can be independently added via 2 rotary Compression controls (range: Off-Max). Compression can squeeze or "compress" an audio signal to decrease the dynamic range between the loudest and quietest signals. The Mackie mixer's Compressor is set at a fixed ratio of 6:1, meaning for every 6dB of input signal past the Threshold, only 1dB will be allowed to pass. Turning the knob clockwise decreases the Threshold level. At the Max setting, the Threshold is set at 0dB.

3-Band Equalization: Each of the inputs has 3-band equalization, with "low shelving" at 80Hz, peaking mids at 2.5kHz, and "high shelving" at 12kHz. Shelving means the circuitry boosts or cuts all frequencies past the specified frequency. EQ controls are provided for mono Channels 1, 2, 3, 4, and stereo Channels 5/6, 7/8, and 9/10, providing 15dB of boost or cut at 80Hz, 2.5kHz, and 12kHz. The "U" symbol indicates the center position (Unity Gain) where there is no change in the signal level.

FX Sends: The ProFX10v3 features an Aux FX Send for each channel strip. The Aux FX knobs tap a portion of each channel's signal to provide an FX mix feeding the internal FX processor, and to feed an external FX processor via the FX Send 1/4" connector. The controls are off when fully turned down (∞), unity gain (no change in level) at the center detent, and providing up to 10dB of gain when fully turned up. Effects are added to the main mix by increasing the level of the "FX to Main" fader. A 1/4" TRS connector is provided for connecting a one-button, on/off footswitch to mute or un-mute the internal effects.

Pan: The ProFX10v3 allows you to adjust how much of the channel signal is sent to the left or right outputs. When the knob is rotated fully left, the signal feeds the main left output. With the knob panned hard right, the signal feeds the main right output. The pan/balance control has a Constant Loudness design which increases or decreases the signal when panning to maintain the same apparent loudness. For stereo Channels 5/6, 7/8, and 9/10 the Pan control acts as a Balance control. Similar to panning, balance increases or decreases the signal amount for either of the two channels in the stereo field.

Mute: Each channel strip includes a Mute button to silence signals on that Channel, both from the FX sends as well as to the Main mix. The Mute buttons will illuminate while engaged.

Level Controls: The ProFX10v3 features a rotary Level control for each Channel strip. Each control includes "U" (unity), for no change in the signal, and can provide up to 10dB of additional signal gain if needed.

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.
• FX Send: A 1/4" TRS jack (bal/unbal) outputs the same signals that are sent to the internal FX processor when a Channel's FX send is turned up. This can be used for running signals through outboard effects processors.
  • Note: The processed signal from an effects unit must be returned on a spare channel, as no return jacks are provided.
• Control Room: Left/Right 1/4" TRS jacks (bal/unbal) are provided for sending signals to a control room amplifier or a headphone distribution amplifier. A corresponding rotary Control Room dial adjusts the output.
• Phones: A 1/4" TRS headphone output provides the same signals as the Control Room outputs. A corresponding rotary Phones dial adjusts the output.
• Foot Switch: A 1/4" TRS jack can be used for quickly muting/un-muting the internal FX with an optional one-button on/off footswitch.

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 12-segment LEDs display the Main Output level, ranging from -30 to 15. LEDs from -30 to 3 light green, while LEDs from 6 to 15 light yellow, indicating the signal level is near clipping. Red Clip LEDs will light if the signal does start to clip.
• Rude Solo: A large red LED will flash when one or more of the Solo switches are engaged.

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/Control Room button allow the blended signal to be sent to the CR and HP outputs.
• 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 ProFX10v3 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:
