AVB ETHERNET AUDIO INTERFACE SETUP SETUP FOR TWO INTERFACES OR Thunderbolt is available on other MOTU AVB-equipped interfaces, such as the 1248, 8M, 16A and 112D. Use this setup if you want to use the Stage-B16 as an AVB Ethernet audio interface for a recentgeneration Mac (i.e. any Mac with a Thunderbolt port on it). Mac OS X Yosemite (10.10) or later is also required for AVB audio I/O. ■ Use a standard CAT-5e or CAT-6 cable. ■ Connect to the computer’s Ethernet port.
SETUP FOR THREE TO FIVE INTERFACES Use this setup if you want to connect three to five MOTU interfaces to your computer using a MOTU AVB Switch™ (sold separately). ■ The connection to the computer can be USB or Thunderbolt (if you have a Thunderbolt-equipped MOTU AVB interface). Use Thunderbolt, if possible, to support a large number of audio streams to and from the networked interfaces. A single Thunderbolt connection supports 128 channels in and out, simultaneously.
SETUP FOR A MULTI-SWITCH NETWORK ■ You can daisy-chain switches in serial fashion, but don’t create loops. For example, switches A, B, and C below are chained properly, but don’t connect C back to A. Alternately, you could connect both Switches B and C to Switch A. Use this setup if you want to connect more than five MOTU interfaces to an extended network that employs multiple AVB switches. AVB Ethernet is an industry standard, so you can use MOTU AVB Switches or 3rd-party AVB switches.
SETUP FOR MULTIPLE INTERFACES It is possible to connect multiple MOTU interfaces directly to your host computer through multiple USB (and Thunderbolt) ports. Alternately, you can connect multiple interfaces, operating as AVB Ethernet audio interfaces, using an AVB switch connected directly to the Mac.
SETUP FOR WEB APP CONTROL The MOTU AVB Control web app gives you access to all settings, routing, mixing, and effects processing in the Stage-B16, and each interface on the AVB network, if applicable. For more info, see “MOTU AVB Control Web App” on page 11. The web app is a web application served by the hardware. All you need to run it is a web browser running on a device that has a connection to your audio interface through USB or a shared network.
Ethernet cable A simple Ethernet cable connection can be used for web app control, even without a USB or Thunderbolt connection to your computer. For example, if you are using your MOTU device as a mixer or audio router, you could control the on-board routing, mixing and effects from the web app through a standard Ethernet connection. Wi-Fi When using standard Wi-Fi as shown, you can control the Stage-B16 from multiple Wi-Fi devices simultaneously.
A TYPICAL STAGE-B16 SETUP Separate mixes can be created using the Stage-B16’s powerful 48-channel, 12-bus mixer and everything can be controlled from a connected laptop, plus multiple wireless devices on the shared Wi-Fi network. Multiple 8-channel stems of audio can be routed among the front-of-house position, the monitor mixer and the playback system.
AUDIO CONNECTIONS MIDI CONNECTIONS Here are a few things to keep in mind as you are making audio connections to your Stage-B16 interface. The Stage-B16 provides MIDI I/O to the computer over USB. Connect your MIDI device’s MIDI IN jack to the Stage-B16’s MIDI OUT jack (Connection A below). Conversely, connect the MIDI device’s MIDI OUT jack to the Stage-B16’s MIDI IN jack (Connection B). Mic inputs with preamps Connect a microphone using a standard mic cable.
Now, all other MOTU AVB devices on the network are resolved to this device. Stage-B16 rear panel MIDI OUT MIDI Device MIDI IN MIDI THRU MIDI cable MIDI IN Additional device Figure 4-8: Connecting additional devices with MIDI THRU ports.
SYNCING MULTIPLE AVB AUDIO INTERFACES CONNECTED TO A MAC There are several options for clocking multiple AVB audio devices connected to the Mac: ■ You can resolve them to an external clock source (like word clock, if available). ■ You can create an aggregate device, as usual. The aggregate device setup panel has a check box called Drift Correction, which sample-rate converts devices that are not synchronized.
HARDWARE INSTALLATION
Part 2 Using the Stage-B16
CHAPTER 5 Presets OVERVIEW AUDIO INTERFACE Because of its advanced, extensive feature set, the Stage-B16 can be used for many different purposes. This chapter discusses common use cases and their corresponding device presets, to help you use the hardware for your needs. Choose the Audio Interface preset to use the Stage-B16 as a standard USB audio interface. Hardware inputs and outputs are accessible from your computer, and the mixer and audio networking features are disabled.
STAND-ALONE MIXER INTERFACE + MIXER Choose the Stand-alone mixer preset to use Stage-B16 as a mixer. Doing so routes all physical inputs to the mixer, with the mixer’s main mix bus and monitor bus going to the Main Out and Line Out pairs. In addition, all inputs are fed to each Aux bus pair (1-2, 3-4, etc.), which are in turn routed to the line out pairs. This means that each aux bus can serve as its own independent monitor mix, with access to any/all inputs.
LIVE RECORDING WITH MONITOR MIXING STAGE BOX Choose the Live recording with monitor mixing preset when you are tracking in the studio. The setup is pretty much the same as for the “Interface + mixer” preset shown in Figure 5-3 on page 46. All physical inputs on the interface are routed to both the computer (for recording) and the Main Mix and Monitor busses in the mixer (for nearzero latency monitoring). USB channels from the computer are included in the Stage-B16’s mix.
STAGE BOX WITH MIXING Similar to the Stage box preset, the Stage Box With Mixing preset routes audio to and from other devices over Ethernet cabling. However, instead of routing incoming network audio directly to the Stage-B16’s outputs, this preset routes the incoming network audio to the Stage-B16’s mixer. The mixer then distributes separate mixes to the Stage-B16’s outputs.
CHAPTER 6 Working with Host Audio Software OVERVIEW RUN THE WEB APP The Stage-B16 provides multi-channel audio input and output for Core Audio compatible audio applications on the Mac and ASIO or Wave compatible applications on Windows, including MOTU’s Digital Performer and AudioDesk, Apple’s Logic Pro and GarageBand, and other third-party software applications such as Ableton Live, Avid Pro Tools, Cockos Reaper, Propellerhead Reason and Record, Steinberg Cubase and Nuendo, Cakewalk SONAR, PreSonus Stu
Specifying the number of computer channels In the web app Device tab (page 13), in the Computer Setup section, specify the number of computer channels for streaming audio to and from your host audio software. You might want enough channels to cover the following: ■ Physical inputs you want to record on your computer. The physical outputs you want to send audio playback to. ■ ■ Any audio streams going to and from the on-board mixer in your MOTU device.
Naming computer input and output channels Click on any computer input or output name in the routing grid (Figure 6-1) to change its name. computer channel row. Now, the mix bus output will be routed to the computer via the channel you selected. Streaming computer audio to and from the on-board mixer In Figure 6-1, you’ll see mixer inputs across the top of the grid (Main, Monitor, Aux, etc.) These are output busses from the Stage-B16’s on-board mixer.
Working with AVB network streams Audio channels going to networked AVB interfaces can be streamed to and from your host audio software through the Stage-B16 connected directly to the computer. For information about how to set this up, see “Mapping computer channels to network streams” on page 67. Mirroring computer channels to multiple outputs Figure 6-1 shows an example of mirroring one stereo audio stream from host audio software to several outputs.
REDUCING MONITORING LATENCY Monitoring latency is a slight delay caused by running an input signal through your host audio software and back out. For example, you might hear it when you drive a live guitar input signal through an amp modeling plug-in running in your audio sequencer.
playback is extremely precise, it is only the monitoring of your live input signal which may be delayed. Adjusting your host software audio buffer Buffers are small bundles of audio data. The Stage-B16 “speaks” to your computer in buffers, rather than one sample at a time. The size of these buffers determine how much delay you hear when monitoring live inputs through your audio software: larger buffers produce more delay; smaller buffers produce less.
■ Responsiveness of transport controls and effect knobs in AudioDesk, Digital Performer or other audio software. ■ Real-time virtual instrument latency. The buffer setting presents you with a trade-off between the processing power of your computer and the delay of live audio as it is being patched through your software.

Enable/disable The rate at which the gate responds, (opens to let signal through) is determined by the Attack parameter.
be flexible enough to cover a broad range of applications. By adjusting Gain and Bandwidth together, you can emulate the smooth and musical character of classic analog EQ circuits, in which the Gain/Bandwidth dependency was dictated by the actual circuit design and electrical components used. Low and high shelf filters The Low and High bands offer a shelf option that is similar to those found in most conventional parametric EQs. COMPRESSOR All mixer input channel strips provide a compressor module.
LEVELER The Leveler™ (Figure 7-5) provides an accurate model of the legendary Teletronix™ LA-2A® optical compressor, known for its unique and highly sought-after Automatic Gain Control (AGC) characteristics. Figure 7-5: The Leveler module. The Leveler is available on the Main Mix bus and all Group busses, including the Reverb bus. A model of an optical compressor An optical leveling amplifier works by shining a light on a photoresistor.
Enabling or disabling the Leveler The Leveler models the LA-2A so closely, it also models the time it takes for an actual LA-2A to “warm up” after it is turned on. Therefore, when you enable the Leveler, give it a moment to “settle” before you begin processing signals with it. Gain Reduction Gain Reduction (Figure 7-5) sets the strength of the signal sent to the AGC model. Makeup Gain Makeup gain (Figure 7-5) amplifies the output signal to make up for gain reduction.
setting represents the bottom frequency of the Mid band. The Ratio determines the length for each band specified in a percentage of the low frequency reverb time. DSP USAGE The DSP Usage meter (item #26 on page 17) shows how much of the available DSP processing power is currently being used by the mixer for the mix and for effects processing. If there aren’t enough DSP resources for all effects to be enabled on a channel, effects are disabled for that channel and all subsequent channels.

■ AVB is already shipping on current Macs — Apple supports AVB on all current shipping Macs, and the Stage-B16 can operate as a standard AVB audio interface when connected to your Mac’s AVB-equipped Ethernet port. MOTU’S AVB IMPLEMENTATION MOTU engineering has faithfully implemented the IEEE 802.1 AVB standard for the MOTU AVB products. This means that MOTU devices are fully interoperable with any 3rd party AVB-compatible device.
to your computer system. Despite the distance, the two interfaces operate as a seamless system, controlled from your computer or iPad. Studio installation A studio installation of three to five interfaces can be handled with a single MOTU AVB Switch. See “Setup for three to five interfaces” on page 33. Networking is ideal for studio installation because you can position interfaces at strategic locations. Running cables becomes much simpler and more cost effective.
A QUICK GUIDE TO NETWORKING MOTU AVB networking has been designed to be powerful, yet straightforward to set up and use. Here are a few things that are useful to know. ■ You can daisy-chain switches in serial fashion, but don’t create loops. For example, in the network below, do not make any additional connections between any two switches. Networking basics ■ Before proceeding below, review the networking connection diagrams on pages 32-34.
SETTING UP A MOTU AVB INTERFACE FOR NETWORKING Depending on the model, MOTU AVB interfaces have the ability to broadcast up to sixteen 8-channel streams to the rest of the network. Conversely, it can “listen” to as many as sixteen 8-channel streams from anywhere else in the network. The specific number of streams supported depends on the model. For each device on the network, set it up for network operation as follows: 1 In the MOTU AVB Control web app, choose the device (item #1 on page 12).
