Series III Interface Mode / WDM Primer

 

The following new features are now implemented in firmware for all Series III Mixers as of firmware version 2.4. These new features were created to allow more flexibility and interest in studio and live streaming use cases.    

 

NOTE: These two features work independently of each other. Interface Mode can be switched on and off as needed. WDM routing is permanently enabled now regardless of whether Interface Mode is switched on or not. 

 

Interface Mode

Purpose

Interface Mode is designed to allow the inputs and outputs of the mixer to be used like a traditional USB interface instead of a mixer with a USB interface connected to the channels.

 

Mode Toggle On/Off

Interface Mode can be initialized (and exited) from either a Series III Console LCD or inside of UC Surface:

Connection Requirements

  • Interface Mode will affect the USB routing and the analog output routing/sources. It should not make any changes to the operation of the AVB routing.
  • Interface mode can not be used on a mixer that is in Stage Box or Monitor Mixer Mode. It should only work for mixers in Stand-alone Mode.

Operation

Access to mix buses with physical outputs is restricted in this mode. Selecting a mix will allow the user to view the mix master settings where they can change the setting for the selected bus between interface and local mix. In this mode, access to the mix sends, mix master Fat Channel, and mix master GEQ is also restricted.

 

Changing an Output Between Interface and Local Mix

In Interface Mode the user can change any available mix between interface and local mix. In UC Surface this option is available in the channel settings area of the mix master channel for each mix. On the consoles this option is also available using the input source buttons for Analog and USB. When set to local mix, the associated mix bus shall operate as it does in the standard mixer mode including the routing of the local mix to the analog outputs. When set to interface the associated mix bus is disabled and the output routing will be sourced from the USB return.

  • Note that linked mixes operate together and will change together.

 

16R Increased USB I/O

With current public release firmware, the StudioLive 16R currently supports 18x18 USB sends and returns. While this can be made to work in interface mode it is not ideal as it doesn't allow for all 16 channels and the mix outputs to be sourced from USB. As part of this firmware update, the StudioLive 16R now has it's USB I/O updated to support an increased I/O count as follows.

  • 24x24 USB I/O

 

Interface Mode Routing

 

When a mixer is set to Interface Mode the following USB routing will be configured.

USB Returns routed directly to Mix outputs and AVB Sends bypassing the local FlexMixes.

WDM Routing

Purpose

In current public release firmware, the WDM driver for Series III mixers only exposes a single stereo send and return. With more and more people using their mixers with conferencing and streaming applications there's a need to support more channels on WDM. While it's not an issue on Mac, most of these applications on Windows do not support ASIO and only use WDM.

In this Beta firmware, the WDM driver is updated to support 8x6 channels of audio with the following default routing:

Example Setup Use Case for WDM:

 

WDM Setup, Interface Mode OFF.

 

SL WDM ½ Input  (Analog Mic in) = Set as Default Input for Windows Sound

SL WDM ⅚ Input (FlexMix ½ Bus) = Set as Discord Input

SL WDM ⅞ Input = Set as OBS Input

 

SL WDM ½ Output = Windows Playback

 

This is an example from my Personal Setup (32R).

 

Analog 1 feeds WDM 1/2, which Windows OS can use for general purpose mic duty.


WDM 5/6 is just FlexMix ½ that has both my Microphone and Playback from OS combined. I use this for Discord, so I can play music from my “mic” while I talk with other players. I can also play other sounds this way.

WDM ⅞ Input is for OBS. Main Mix is broadcast mix, essentially.

Obviously, just an example of what can be done.
