- Navigate to the About / Update tab to verify the current firmware version. If the system detects a newer version, press Update. Do not disconnect the power under any circumstances during the flashing process.
- In the Services menu, log in to the streaming platforms you use (Amazon Music Unlimited, TIDAL, Beatport, Beatsource, or SoundCloud GO+) by scanning the on-screen QR code with your smartphone camera.
- Access the Mixer tab to adjust the Crossfader curve, configure cue routing, and set attenuation levels (Talkover) for the two independent microphone inputs.
Using Multi-Zone MPCe Pads
The hardware introduces 16 new-generation MPCe pads. These pads feature velocity sensitivity, pressure sensitivity, and three-dimensional detection technology (X and Y axes), transforming the surface into an advanced gesture controller.
- Press the Hot Cue button to assign and trigger location points. Apply continuous pressure on the pad to modify the RGB backlight intensity or alter secondary parameters assigned in the settings menu.
- Activate Loop or Roll mode by pressing their respective mode buttons. Slide your finger vertically on the pad (Y-axis) to alter the loop beat fraction in real-time without needing to use the auto-loop encoder.
- Press the Sampler button to access the 16-slot sample bank. Strike the pads with different levels of force; velocity sensitivity will determine the output volume of each audio sample.
- Configure the pads in XY FX mode from the touchscreen so that sliding your finger across the rubber surface assigns filter sweeps or modulation alterations to the track currently playing.
Track Isolation with Integrated Stems
The PRIME 4 G2 processor allows for rendering and playing Stems files directly from flash memory or USB drives, separating the audio file into four independent stems without relying on a laptop.
- Load a track into any of the four decks by swiping the song to the right on the touchscreen or pressing the navigation encoder.
- For drastic and immediate isolation, press the physical Instant Acapella or Instant Instrumental buttons located above the pad section. The system will silence the musical backing or the voice in milliseconds.
- For granular control, press and hold the mode button assigned to Stems. The four bottom pads will light up representing the Vocal, Melody, Bass, and Drums stems.
- Press a specific pad to Mute that element, or hold the Shift button along with the pad to Solo it.
- Activate the Stem Level EQ function from the touchscreen. This will reassign that channel's EQ knobs (High, Mid, Low) to control the individual volume of the voice, melody, and rhythm section, allowing for progressive mixes.
- Apply the Stem Echo-Out effect by pressing the pad corresponding to the voice and the effect button simultaneously. This will generate a delay tail exclusive to the vocal track while the instruments continue playing dry.
Effects Management: Main FX, Touch FX, and Fader FX
The signal processing workflow is divided into four distinct modules, offering exhaustive control over audio manipulation.
- Operate the Main FX using the dedicated OLED screens located above each pair of channels. Turn the Select encoder to choose the algorithm, adjust parameters with the Time and Parameter knobs, and trigger the effect by lowering the Toggle Switches.
- Activate the Touch FX interface by swiping the waveform view to the left on the 10.1-inch screen. Touch and drag your finger across the on-screen X/Y grid to apply complex combinations of filters and delays with a single movement.
- Apply Sweep FX by selecting one of the four central buttons (Filter, Echo, Wash, Noise) and turning the large knob located below each channel's EQ section.
- Use the new Fader FX function by pressing the enable button located next to the dual-rail channel faders. By moving the volume fader up or down, you will automatically control the depth of the assigned effect, allowing you to execute drops and transitions with one hand.
Native DMX Lighting Control
The system integrates a hardware interface for lighting control, eliminating the need to use external USB dongles or third-party software on a computer.
- Connect a standard DMX cable from the DMX Out port on the rear panel directly to your first light or lighting interface.
- Swipe down on the main screen to access the control center and open the Engine Lighting module.
- Select Basic mode if you want the system to analyze the track beatgrid and generate an automatic light show synchronized to the tempo.
- Select Pro mode if you have previously exported a custom project from the SoundSwitch desktop software.
- Assign override functions to the MPCe pads to trigger strobes, change color palettes, or activate smoke machines manually by hitting the pads during the performance.
- Link smart home lighting systems by accessing pairing options for Philips Hue and Nanoleaf devices via the same Wi-Fi network.
Zone Output and Jog Wheel Configuration
The Zone function allows you to output a completely different audio signal to a second room, turning the unit into a dual routing matrix. Additionally, monitoring of the main track is supported by the new information-display motorized platters.
- To activate the second room, press and hold a playlist in the library and select the Send to Zone option in the pop-up menu.
- The system will automatically reserve Channel 4 (or another assignable channel) to play the list in continuous mode with automatic crossfades to the Zone Out ports.
- Adjust the volume and EQ the frequencies of the second room using the Zone Level and Zone EQ hardware knobs located in the top right corner of the chassis.
- Monitor the status of the main decks by observing the central high-resolution screens integrated into the 8-inch Jog Wheels. These screens will show you the album art, playhead position, active Stems data, and Hot Cue proximity warnings.
OmniSource and Bluetooth Integration
The OmniSource architecture is designed to unify the standalone hardware ecosystem with mobile devices and desktop software in a single mixing session.
- Activate the Bluetooth receiver in the quick settings menu and pair your smartphone or tablet.
- Assign the incoming wireless signal to the Bluetooth Deck. This will allow you to apply EQ, filters, and Main FX to the audio from your mobile phone as if it were a local file.
- Connect your laptop to the USB Type-C (Computer/Media) port located on the rear panel using a high-speed data cable.
- Tap the computer mode icon on the touchscreen to switch the system. You will be able to control third-party software applications (such as Serato DJ Pro, VirtualDJ, or Algoriddim djay) on two channels, while playing audio from a USB thumb drive on the other two channels simultaneously.
