CROSSFADER assign routes the Program to the Crossfader A-side, B-side, or after the Crossfader (POST).

FlexFx assign takes the Program out of the Main Mix and sends it to the FlexFx Loop.

CUE select assigns the Program to the headphone monitor.

Each of the four Program channels has a signal level meter with peak-hold.

The Crossfader is a no-noise, no-bleed magnetic fader.

The fader panel is easily field-replaceable, requiring only a philips screwdriver.

The four faders and crossfader have contour controls on the front panel, allowing adjustment from a smooth transistion to a fast cut.

The 1/4" and 3.5 mm headphone jacks can be used at the same time.

The FlexFX Mix Level controls the level of the FlexFx signal going to the Main Mix.

Two Microphone Inputs are fully independent, each with these controls:
• Large illuminated On / Off switch.
• LEVEL control.
• PAN the Mic left or right.
• HIGH / LOW 2-band, full-cut EQ range is Off to +6 dB with no EQ in the center.
• FlexFx takes the Mic out of the Main Mix and sends it to the FlexFx Loop.
• PAN the Mic left or right.

Each Mic has a signal level meter with peak-hold.

MIC 1 allows +48 volt phantom power with a rear panel on/off switch.

MIC 2 allows mic or line-level input with a rear panel switch.

The Main Mix is made from these signals:
• PGM 1, PGM 2, PGM 3, PGM 4
• MIC 1, MIC 2
• Session Input
• FlexFx Mix

The Main Mix has a Left / Right Balance control, and can be switched to Mono.

The Main Mix has these outputs, each with it's own LEVEL:
• MAIN OUT on XLR jacks
• BOOTH OUT on 1/4” TRS jacks
• SESSION OUT on RCA jacks

The Session Input operates like a fifth Aux input from RCA jacks.

Individual CUE buttons are provided for PGM 1, PGM 2, PGM 3, PGM 4 and the FlexFx Loop.

The Headphone Monitor provides stereo or mono split-cue operation.
• In Stereo operation (unlit), the PAN control pans between Stereo Cue and Stereo Main Mix.
• In Split Cue operation (lit), the PAN control pans between Mono Cue in the left ear and Mono Main Mix in the right ear.

The Headphone LEVEL controls both of the front panel headphone output jacks.

The FlexFx Loop provides the ability to create a sub-mix that may include any combination of the four PGM input buses and both Mics. This configuration allows you to:
• Create a unique submix.
• Add internal or external effects to a submix.
• Record a submix.
• Rehearse a submix.

USB and analog FlexFx Loop Inserts are selected individually:
• The EXT. INSERT button engages the external analog FlexFx Loop.
• The USB 5 INSERT button engages the USB insert.
Both inserts are available with or without the use of an internal effect.

Individual internal effects are selected on/off using one of the six effects buttons. One internal effect is selected at a time.

With the front panel FlexFx Mix Level turned down, FlexFx On or Off, create a submix, add effects (or not) and Cue or rehearse the mix before bringing it into the Main Mix with the FlexFX Mix Level.

More details about using effects are in the Operator's Manual.

Both left and right side controls are the same, except for the SHIFT and CONTROL POINT buttons.

The SHIFT button's primary function is choosing which of the four decks the control strips are in command of, toggling between decks 1/2 and 3/4. Hold SHIFT and press a CUE button to access customizable groups.

The CONTROL POINT button selects which computer is in control of the mixer's control strips.

The BACK buttons shift focus between the crate list and the track list.

The SCROLL knob scrolls library/crates. Clicking the knob selects the focused crate or track, or loads the track to a deck.

The AUTO / MANUAL button alternates the mode of the LOOP controls.

When in AUTO mode the LOOP buttons have control over the Scratch Live auto-loop features, lighting the button green.

When in MANUAL mode the LOOP buttons have control over the Scratch Live manual looping features,lighting the button orange.

SELECT knob adjusts the Loop length.

DELETE LOOP/CUE allows deleting loops and cue points.

CUE POINTS buttons for each Deck recall cue points with "Hot Cue" support in Scratch Live.

DELETE LOOP/CUE allows deleting loops and cue points.

PGM Inputs 1-4
There are four stereo analog inputs for PGM 1 through PGM 4. Any of these analog inputs may be set for Phono Input, Line Input or S/PDIF using the P - L - S switches. Any of the four analog inputs may be used for Scratch Live vinyl emulation control. Input 1 or Input 2 may be selected for Scratch Live Virtual Deck 1 control. Input 3 or 4 may be selected for Scratch Live Virtual Deck 2 control. Control input sources are selected in Scratch Live software.

Mic Inputs
The Mic Inputs will accept an XLR 3-pin plug, a balanced 1/4" TRS (tip-ring sleeve) plug or an unbalanced TS (tip-sleeve) plug. Mic 1 has switchable phantom power, and Mic 2 has switchable Mic/Line level.

Two USB Ports
There are six stereo record channels and five stereo playback channels. These channels are simultaneously available on two USB ports, allowing two computers to share the mixer. This allows two DJs to play together and supports uninterrupted transitions from one DJ to another. The six stereo record channels are sent to both USB ports. The five stereo playback channels from each port are summed in the mixer. USB audio is 32-bit floating point sampled at 48 kHz.
