Description

MOTU LP32 Audio Interface Overview:

The LP32 is a flexible ADAT optical “lightpipe” audio interface, router, splitter, converter and mixer with AVB/TSN networking. It is ideal for routing optical digital audio in live performance systems, network installations or recording studios of any size.

32 channels of ADAT “lightpipe” I/O
The LP32 provides four independent banks of 8-channel ADAT optical I/O, 64 channels of USB I/O, 32 channels of AVB-TSN network I/O and a headphone output, for a total of 258 simultaneous I/O channels.

High-performance computer connectivity
New, optimized drivers for both Mac and PC deliver ultra-low latency performance. With a high-performance DAW such as Digital Performer, the LP32 delivers an astonishing round trip latency (RTL) of 1.70 ms (milliseconds) on OS X and 1.71 ms on Windows over USB (at 96 kHz with a 32-sample host buffer).

A flexible digital converter, router, splitter and repeater
Send any input to any output, or split to multiple output channels. Convert any format to any other (Optical, AVB-TSN and USB). Includes routing to and from the computer, plus any devices on the AVB-TSN network.

DSP mixing and effects processing
The LP32’s 48-input digital mixer delivers 7 stereo aux busses, 3 groups, access to 64 network inputs, and DSP effects, including classic reverb, EQ modeled after British analog console EQs and compression modeled after the legendary LA-2A compressor. If you know your way around a large-format mixing console, you’ll feel right at home. With 32-bit floating point processing, the LP32’s DSP engine delivers virtually unlimited headroom and the utmost in sound quality.

Stand-alone operation with wireless control
Connect an Apple Airport or other Wi-Fi router with a standard Ethernet cable for wireless control of device settings, powerful 48-channel mixing and DSP effects.

Web app control
The software that you use to control the LP32 doesn’t reside on your hard drive. It’s a web app served from the hardware itself. This means you can control the LP32’s on-board DSP, mixing, and device settings from the web app software running in your favorite web browser on the computer, or even a tablet or smartphone on the same Wi-Fi network as your computer.

Comprehensive Metering
The full-color LCD lets you view all signal activity at a glance with detailed metering for all I/O. Access hardware settings from a simple and convenient menu.

Word Clock
Standard word clock input and output allows you to resolve the LP32 to other digital audio gear or house sync.

Convenient headphone monitoring
Use the assignable front-panel headphone output with volume control to monitor any stereo channel pair.

Mix and match with other MOTU gear
An included mounting bracket kit joins the LP32 side-by-side with any other MOTU half-rack unit to create a single rack-space configuration consisting of customized analog, digital and/or MIDI I/O configuration tailored just for you.

Audio analysis tools
Analyze and scope your audio with advanced diagnostic tools, including a full-screen real-time FFT display, spectrogram “water- fall” display, full-featured oscillioscope, X-Y plot and phase analyzer.

AudioDesk
Includes AudioDesk workstation software for Mac and Windows with 24-bit recording, sample-accurate editing and 32-bit mixing and mastering

Support for TOSLink
Each optical input or output is individually switchable to stereo TOSLink (optical S/PDIF), regardless of the current sample rate setting (from 44.1 to 96 kHz).

Flexible router, converter and splitter
Send any input to any output, or split to multiple output channels. Convert any format to any other (Optical, AVB-TSN and USB). Includes routing to and from the computer, plus any devices on the AVB-TSN network.

Stand-alone operation with wireless control
Connect a standard Wi-Fi router with a standard Ethernet cable for wireless control of device settings, routing/splitting, powerful 48-channel mixing and DSP effects.
