he U46XL is a powerful multi-purpose 4-in 6-out multi-channel audio interface designed for various recording applications at home or on the road. The U46XL is the successor of to ESI Audio's famous U46DJ interface.

As its predecessor, it provides 2 stereo line inputs, a microphone input with +48V phantom power and a headphone output. A main difference is the improved analog circuitry improving the audio quality as well as the professional microphone preamplifier with XLR input. This makes the U46XL the perfect solution to record signals from dynamic or condenser microphones on the road or in your studio.

The unit also features an instrument input (Hi-Z), typically to connect a guitar directly to it. Two totally separate stereo line input on the backside provide 4 simultaneously usable input channels at one time. There are also 6 independent individual outputs on the backside, perfect for multi-channel playback applications like to provide individual outputs for software synthesizers, to provide independent playback channels for DJ software or to provide surround playback capability via a 5.1 setup. A separate mix output with professional TRS outputs could be used to connect U46XL to professional stereo studio monitors.

A cool feature is the DirectWIRE support in the driver, allowing you to record signals from one application to another internally. U46XL works with this driver based on our EWDM technology under Windows XP and Windows Vista/7, however U46XL is also Mac OS X compatible.

U46XL ships with Cubase LE 4 from Steinberg for Mac and PC to start recording on a professional level right out of the box.

MOTU FireWire audio interfaces are fully compatible with FireWire 800-equipped Macs. All you need is a standard FireWire 400-to-800 cable. Just plug in and go. The FireWire bus operates at 400 Mb/sec, providing the same high speed, low latency and rock solid reliability that MOTU FireWire interfaces are known for.

The 8pre is the perfect way to instantly add eight more mic inputs to any audio interface or digital mixer with optical I/O. If you have a MOTU interface with on-board CueMix DSP mixing, such as the 828mkII, 896HD or Traveler, the 8pre inputs appear directly in the host interface's CueMix mixer to becomes a transparent extension of your system, operating together with your primary interface as a single, integrated unit — even when the host interface is not connected to a computer and is instead operating as a stand-alone mixer.

If you have a 2408mk3, digital mixer or other audio device that supports 96kHz optical and also has two optical inputs, the 8pre connects to it via both optical ports to provide a full eight channels of analog to optical conversion at the 88.2 or 96kHz sample rates.

Yamaha GO46 FireWire Interface

The GO46 FireWire interface from Yamaha provides a means to stream
high-quality 24-bit/192kHz digital audio and MIDI into a computer. Connect
it to a laptop, and you've got a rugged and portable interface that can go
anywhere you go, hence the name "GO46." This box is the ideal interface
for great-sounding audio on the "GO."

Yamaha GO46 FireWire Audio/MIDI Interface At a Glance
Premium Mic Pres and Inputs
FireWire Connectivity
Flexible Connectivity Including S/PDIF, Insert Points, and MIDI

Premium Mic Pres and Inputs
The GO46 features combo mic/line terminals (for both XLR and phone jack)
 on the front panel. Phantom power is also available and independently
switchable for each input channel. In other words, you can use a condenser
microphone on channel 1 with phantom power switched on to capture the
delicate sounds of a vocal while simultaneously recording an electric/acoustic
guitar plugged into channel 2. These combo inputs are captured at up to 24-bit/
192kHz resolution. This pro-level quality makes the GO46 perfect for any type
of recording, and allows you to capture the full details and nuances of the
original source - from the breathiness of a vocal to the delicate finger slides of
an acoustic guitar performance.

FireWire Connectivity
The FireWire equipped GO46 not only offers the convenience of one plug
connection to a computer, but the GO46 can be powered via bus power
from the FireWire port. Connect the GO46 to the FireWire terminal of a
laptop and you've got and extremely powerful and portable recording studio
that will fit in a backpack. This is also great for using the GO46 in places
where electrical outlets can be scarce, like local clubs.

Flexible Connectivity Including S/PDIF, Insert Points, and MIDI
In order to maximize the flexibility of the GO46, Yamaha included virtually
any kind of connection you might need on location recording gigs. Two
insert points allow for connection to outboard gear like compressors or EQs.
MIDI in/out allows for connection of MIDI sound modules or instruments.
S/PDIF jacks are great for inputting digital signal from another interface or
throughputting the GO46 signal to a digital mixer, separate digital recorder,
or any other digital device.
