THE SADiE LRX2 Location Audio Workstation has been designed to fulfil the needs of an ever more complex recording
environment and to serve a wide variety of remote recording applications. It is as effective in capturing the original
soundtracks for film and television productions as it is for producing location multitrack audio recordings for release
on distributed media such as CD or DVD.

The LRX2 combines SADiE's proven high-quality professional audio input and output 'slither card' I/O modules with a tactile
hardware control surface and the ability to use a standard laptop via USB2 as the host computer to provide a powerful and
effective combination according to the particular application. 

Based on the original innovative SADiE LRX introduced in 2005, the LRX2 takes the concept a significant stage further by the
provision of additional DSP power, plus control surface enhancements. This extra DSP enables recording for up to 64 channels
using the MADI interface, or 48 balanced analogue inputs which can be Line level or Microphone inputs with Phantom power.
Sampling rates up to 96kHz/24bit are supported with a variety of dedicated input cards. For maximum compatibility, these
cards are the same as those employed in SADiE's flagship PCM-H64/PCM-H128 multitrack editing workstations.

The LRX2 hardware comprises a small assignable mixer with 8 motorised faders; including pre-fade listen and dedicated record
enable buttons; a complete editorial interface with fully weighted jog wheel and ergonomic editing buttons; locator memories;
transport controls and a headphone monitor output with separate headphone level control and a side-mounted microphone
input socket for slate/talkback functions. The dedicated and assignable editing function buttons include Scrub, EDL/SRC, Xfade,
Select, Zoom, In, Out, Razor and Preview plus the weighted jog wheel. The built-in mixer with automation and the 8 motorised
faders allow rapid switching between the input and output busses with simple bank switching, pre-fade listen over headphone
output, direct record track select, plus locator buttons and a separate monitor buss. The LRX2 is complemented with
professional interfaces to lock the machine to timecode, video ref or gen-locked incoming AES ref, depending upon the application. 

In addition to the current V5 operating software, the LRX2 is supplied with the dedicated SADiE MTR on-screen graphical user
interface, which greatly simplifies user operation and enables the operator to quickly get to grips with the system. Sessions
created in MTR mode are fully compatible with, and may be opened in, SADiE V5 software for more sophisticated post
production operations. Full Metadata support is provided in MTR mode to allow the operator to easily keep track of recordings
and takes. 

The flexibility of the LRX2 hinges on its ability to utilise the same high quality I/O cards as the PCM-H64 and PCM-H128
multitrack workstations, according to a particular application; be it a multitrack analogue recorder; a multitrack digital recorder;
a location sound recorder and playback device; on-set ADR; etc. 

Input and output options are provided by three 'slither' receptacles which can accept any of the SADiE slither interface cards.
In addition to the standard 16ch ADC/DAC and AES/EBU digital I/O cards, a switchable high quality 16ch mic/line card is
available with 48v phantom power and selectable gain steps. A dedicated MADI interface card is also now available which facilitates easy interconnection of up to 64 tracks to studio or live digital consoles.

This in-built flexibility allows the user to customise the LRX2 to suit their circumstances rather than having to modify their
working techniques to cope with the inadequacies of their equipment. 

The LRX2 utilises a standard PC Laptop running Windows XP® with a USB2 interface. A second external drive may be simply
attached, via USB2 or Firewire, to mirror recordings and provide a simultaneous safety copy. An added benefit is that a
DV-AVI video stream may be simultaneously captured for playback or ADR whilst the actors are still on set.

Slithers currently available are as follows:

16 channel Mic/Line inputs

16 channel D/A line outputs

16 channel AES3 digital I/O

64 channel MADI I/O
