WMD Performance Mixer MKII

MUSICAL FEATURES

Welcome to the WMD Performance Mixer MKII - 8 years after the release of the MKI, the MKII has been further improved based on the valuable feedback we received.

Compared to the MK I, there are further improvements in sound quality and reduced noise bleed, panning/crossfader switching, overall modularization through channel strips, improved operability by placing all jacks on the left, output of controller movements via MIDI, and further expandability.

The following expanders will be released:

• DB25 expander/Direct Out Expander: For each channelExpander that provides individual outs. The lineup includes two types: a DB25 expander with D-Sub balanced output, and a Direct Outs expander with 3.5mm unbalanced output. EitherIt is now possible to extract both pre- and post-fader signals.
• Returns Expander: Adds an Aux stereo return that is partially missing on the main unit.
• Channels Expander: Expands 4 stereo inputs. Can also operate as a standalone mixer. Connect up to 1 units to a single Performance Mixer MKII and handle up to 4 stereo inputs.

Features

• 8 stereo or dual mono inputs
• 2 stereo aux outputs
• Main/Secondary mix bus (AND/OR assignment)
• Balanced master output in 3.5mm TRS
• Soft mute on each channel
• Stereo cue mix bus (TRS output jack)
• 3.5mm headphone jack with DJ style cue/mix pot
  
• Improved maintainability by channel stripping
• Expandable to up to 24 stereo channels using an expander
• CV control of pan, level, Aux1, Aux2
• The MIDI output sends movements including pan, level, and Aux1 and Aux2 CV, allowing you to capture the mix in your DAW.
• Pre/post fader balanced DB25 or unbalanced 3.5mm direct outs
  
• Always saves settings and status on power-up
• Input gain: -12dB to +20dB (line level boost possible)
• Fader gain: -100dB to +5dB (same for Aux1 and Aux2)
• Pan curve: -100dB to -3dB (Center)
• All inputs and outputs are in phase
• -20dB high pass filter at 1.3Hz

How To Use

Interface

• INPUTS: IN LEFT is internally wired to IN RIGHT.
• GAIN: Each channel has a gain trim range of -12dB to +20dB, making it easy to use with line level devices.
• GAIN CLIP LED: Lights red 1dB before the input stage clips.
• LVL FADER: Smooth, intuitive curves make it easy to adjust mix levels. There is a yellow indicator to show the level.
• MUTE: Press the white button to soft mute the channel and the red LED indicator will illuminate.
• PAN: When the toggle switch is set to PAN mode, the P/XF pot adjusts panning.
• X-FADE:When the toggle switch is set to X-FADE, the P/XF pot mixes the left and right inputs and sends them as a mono signal to the center of the mix bus.
• LVLCV: This toggle switch is normally down in SUM mode. When switched up, the fader becomes an attenuator for the CV jack. This is useful if you want to use the fader as a VCA instead of a mix.
• AUX1: This stereo send is always post-pan/fader. CV is added to the pot.
• AUX2: This stereo send is switchable post-pre-fader and can be used in SUM or VCA mode.
• CUE: If you hold down the CUE button and press a channel button, the green CUE LED will light and this channel will be routed to the stereo CUE bus.
• BY BUS: Hold down the BUS button and press the white channel button, the BUS LED will have 3 states. OFF - Routing to master mix only, BLUE - Routing to both master and bus mix, PURPLE - Routing to bus mix only.
• AUX RET: Stereo input mixed before master insert effects loop. You can input one stereo pair of AUX send effect returns.
• BY BUS: Stereo output of secondary routing bus.
• AUX1 / AUX2: Two bus stereo outputs.
• MASTER INSERT: Main mix stereo send and return. Used for master effects.
• MIX IN: Stereo input summed after master insert.
• MSTR OUT: Stereo balanced output. This is the master output. Behind the panel is a 1-pin header for connecting to the Intellijel's balanced 4/6-inch output via a ribbon cable.
• METER: LED VU meters indicate the level of the final mixing bus before the master pots.
• CUE/MIX: Control the headphone mix. CCW is cue bus, CW is main mix bus.
• PHONES LEVEL: This is the level of headphones. The headphone output jack is located on the far left side of the PM MKII.

Mixer Settings

You can change various settings by pressing the Group, Bus, and Cue buttons simultaneously and then pressing channel buttons 1 to 8.

・CH.1 BUS MODE
Press the Group, Bus, and Cue buttons simultaneously and then press Channel button 1 to cycle through the bus settings.

BLUE:Parallel Processing (default)
When you hold down the BUS button and press a channel button, the BUS LED will light up blue and that channel will be output from both the Master Out and the Bus Out.

PURPLE:Submix Processing
When you hold down the BUS button and press each channel button, the BUS LED will light up blue and that channel will not be output from the Master Out but only from the Bus Out.

NET:Tri-State Mode
By pressing the BUS button and each channel button at the same time, the BUS LED will switch between BLUE, PURPLE and OFF, allowing you to set the BUS individually for each channel.

・CH.2 MUTE ON BOOT
Press and hold the Group, Bus, and Cue buttons simultaneously while pressing Channel button 2 to toggle between loading the last saved mute settings the next time you start up or turning them all off.
Channel 1 flashes:All mutes are off at startup (default)
Channel 2 flashes:Last mute setting is on at startup

・CH.3 GROUP MODE
Press the Group, Bus, and Cue buttons simultaneously and then press channel button 3 to switch between GROUP combo mode and recall mode.
Channel 1 flashes: COMBO MODE
While pressing the GROUP button, set the MUTE, BUS, and CUE for multiple channels, and when you release the GROUP button, all of these settings will be reflected simultaneously.
Channel 2 flashing: GROUP RECALL MODE (default)
When you press and hold the GROUP button and press any channel button, the MUTE, BUS, and CUE settings stored in the slot will be recalled the moment you release the channel button. At that time, the BUS MODE will also switch, but the settings will not be changed.

To save the settings, press and hold the GROUP and CUE buttons and then press any channel button to save to that slot.

Firmware update

The Performance Mixer MKII has a microSD memory card slot for firmware updates.
The SD card is only used to load new firmware, and if you leave it in the device, it will try to update the firmware every time you turn it on.Please always remove the SD card before use.

Recommended memory cards
The microSD memory card must be SanDisk SDHC type 8-32GB. Other brands and types are not supported.
The tested memory cards are as follows:

Update Procedure
1. Format the card to FAT32.
2.https://wmdevices.com/products/performance-mixer-mkiiDownload the latest firmware from.
3. Load the downloaded firmware file "PM_MKII.bin" into the memory card directory.
4. Turn off the Performance Mixer MKII.
5. Remove the mounting screw and lift the left side of the module.
6. Insert the prepared microSD memory card into the slot on the back of the left side board of the module.
7. Power on the Performance Mixer MKII. The LED should turn red briefly while it reads the card. If the LED remains red there is an issue with the microSD or firmware file.
8. Green LED indicates microSD/firmware file is OK and firmware flash is being prepared.
9. When firmware writing begins, the BLUE LED will flash for about 10 to 20 seconds.
10. Once the update is complete, the LED will turn green and the module will reboot.
11. Turn off the power to the module, remove the memory card from the module, remount it in the case with the screws, and the update is complete.
