General product description
The NAGRA LB has been designed as the natural successor to the ARES-C recorder,
and it is specifically designed for broadcast applications although naturally it
is also very well suited to a multitude of other recording applications. Similar
in size to the ARES-BB+ the LB offers communication possibilities never before
seen in a professional broadcast recorder.
It offers two analogue audio inputs and a single stereo digital input. The Nagra
LB will record in either PCM linear audio or in MPEG-1 layer II or MP-3
compressed audio formats. The inputs are equipped with traditional NAGRA
microphone pre-amplifiers for dynamic and phantom +48V microphones. The LINE
input will accept up to +24dB. The audio levels and current operating mode of
the recorder are shown on the colour display mounted on the front of the unit.
Above the potentiomenters three leds are fitted to indicate audio levels as on
the ARES-BB+ and Nagra VI. The front display becomes inactive when the editor on
the top panel of the machine is in use.
Recording medium and formats
The Nagra LB is fitted with an internal 2GB NAND flash memory which serves two
important rolls. Firstly as a back-up media should the extractable compact flash
card be full, but also as a spontaneous memory for recording while the
extractable card is changed. Simply pressing the "Hot Swap" button next to the
slot will allow the card to be replaced even while the recorder is actually
recording. The file formats of the LB can be selected from PCM linear, MPEG-1
Layer II or MP-3 according to the specific application. The files are Broadcast
Wave format and are compatible with both Mac an PC based systems.
Editing and communication
The top of the LB is equipped with a full audio editing system with its own
dedicated colour display. This allows in-the-field editing and gives a graphic
waveform display. Once the editing of the audio material is complete, the file
can be transmitted to the studio either over IP (through the ethernet
connection) or via a GSM phone through the Bluetooth option. Naturally the USB
port also serves as a generic drive when connected to a computer to file
transfer can also be done this way. Removal of the compact flash card is a final
possibility for removing the audio from the recorder. The HOST USB port can also
be used for file transfer to a memory stick.
The LB is powered by 8 "AA" batteries in a removable battery compartment. This
may be fitted with rechargeable cells if required, which are in turn charged
through the Hirose connector on the battery box body.
