The 8M is one of many new high-performing audio interfaces MOTU combining high quality audio, a complete virtual mixing console with features at the forefront of technology.

Ethernet AVB: a high-performance audio network for 8M in industry standards.

Developed by IEEE 802.1 AVB extension (Audio Video Bridging) to Ethernet standard now becomes a standard feature of all MOTU AVB audio interfaces for an immediate and positive impact on your audio work. The AVB audio network holds the promise of a standard audio system, really professional and stable that will change your approach to the distribution of audio input / output for necklace to your needs.

WHAT DOES THE AVB?

The AVB audio networking provides two advantages:

• Flexibility, perfect control of all your internet from any host audio system on the same network with WiFi devices like the iPad or iPhone;
• Opportunities to expand your system and almost unlimited opportunity to build its own facility.

home studio in Extension

Start with MOTU AVB interface you need and add one second AVB MOTU audio interface with a single Ethernet cable.

studio system

Place three to five MOTU AVB interface to strategic places in your studio set according to your needs and connect them to the distributor (Switch) MOTU AVB.

multiroom installation

Install a MOTU AVB interface in every room of your studio, church music department or business video. Are routing audio from any source to any destination at your convenience and with a latency in the millisecond.


concerts Systems
Plug your monitor console, helmets monitors and recording system with a long cable (100 meters) for a complete network. Manage audio routing groups with 8 channels and ultra-low latency, then set your system for different concerts configurations.

Installation XXL

With long cable and a standard network structure MOTU AVB systems perfectly match the facilities of large areas such stadiums, arenas, theme parks, resorts, casinos, temples, audio / video facilities, schools , universities, and many others.

No licensing fees.

As AVB is an open industry standard (non-proprietary), there are no license fees to pay. Instead, the cost goes directly to the development of the most reliable network for your comfort.

A 512-channel audio system.

The AVB is designed to handle hundreds of channels of audio over a network. A network MOTU AVB (with MOTU AVB interfaces and AVB Switch ™) manages up to 512 channels. In addition, each MOTU AVB device can stream and allows simultaneous multiple streams 8 listen networking channels. The number of supported flows varies depending on the device, the 8M proposes the maximum: 16 flow (128 channels) in simultaneous I / O.

Ultra low network latency.

Standard latency AVB networks is set to 2 milli-seconds. The MOTU AVB network has an amazing latency of 0.625 milliseconds (fixed) even with 7 "hops" (switches) and hundreds of meters of cable. This represents only 30 samples with a system operating in 48 kHz. By adding the low latency converter MOTU AVB interfaces obtained 1.29 millisecond latency of an analog input to an analog output in spite of the switches 7 and potentially hundreds of meters of cable. 96 kHz the total latency is less than 1 millisecond. In comparison, other proprietary network systems have a variable and unpredictable latency 2 to 5 milliseconds.

input Latency analog output at 48 kHz:

- A / D: 12 samples.
- FPGAs Input: 4 samples.
- FPGA output: 4 samples.
- Input / Output DSP 6 samples.
- D / A: 6 samples.
- Total inputs / outputs: 32 samples.
- Network: 30 samples.
- Total / O + network 62 samples or 1.29 milli-second.

Temporal Accuracy and network synchronization.

The AVB has its own network timebase for precise sample-accurate with all connected devices. The timing accuracy is lower than the nano-second. Better yet, the MOTU AVB network includes synchronizing a click: press the "Become Master Clock" button (becomes the master clock) from the internet under the MOTU AVB chosen to be the reference horologe and all other devices connected to the network will be immediately enslaved to it.

guaranteed Quality of Service.

Stream Reservation Protocol AVB offer a guaranteed quality of service for each audio stream. Once a network connection is made, AVB will guarantee that the audio stream will be interrupted by any other network traffic of any kind.

True operations "Plug and Play".

The MOTU AVB system has been designed from the start to automatically recognize any device, number and connection. Just plug your MOTU AVB AVB interface on a standard plug and go. You do not need professional address (IT) to configure the network, AVB has autonomous management network.

A jump to the standard Ethernet.

The AVB can co-exist with standard Ethernet networks to connect standard devices like a Airport terminal, wireless router, Ethernet connections or complete Ethernet network in your home, office or studio. This allows you to control your AVB devices around according to your convenience and access and to the Internet for firmware updates from the cloud servers MOTU, for example.

Large cable lengths.

Simple AVB network connection up to 100 meters with a standard cable type CAT-5e or CAT-6. Fiber optic cables can be much longer. With more distributors (switches) - up to 7 "hops" (switch to switch connections) - you can create a network covering large distances if necessary.

connections in Thunderbolt or USB.

MOTU is the first to combine the AVB network connectivity with Thunderbolt and USB 2.0. The MOTU AVB network requires no PCIe card slot. Instead, you can easily connect your / your computer (s) via USB or Thunderbolt.

Connect multiple computers.

The MOTU AVB network can accommodate as many computers that can connect with a direct access to them to all devices and connected audio stream. All computers and network devices will be synchronized with each other by the master clock source.

256 channels / O.

With Thunderbolt, the AVB MOTU interfaces support up to 256 simultaneous channels of audio inputs and outputs (128 inputs and 128 outputs). If your computer has multiple Thunderbolt ports, such new Mac Pro Cylindrical, you can access the network through multiple connections, each supporting 256 channels.

Configuration star.

The MOTU AVB uses a star network configuration, which is more flexible than a serial connection, enabling different branches to be fueled by various sources.

Internet interface and wireless control.

MOTU AVB The system can be controlled from the Control AVB software that works with any browser either on a laptop, tablet or smart phone, even in WiFi. Control your system from multiple devices simultaneously from different platforms: Mac, Windows, Linux, iOS, Android, etc.).
