Chapter 2 - Introduction
2-2 Courier User Handbook
Courier can sample audio in stereo or mono and audio can be stored in industry
standard linear files or it can be compressed as it is recorded using the mpeg 2 layer
2 compression standard.
It's likely that if you use a specific hard-disk playout system, or prefer a particular
audio compression type you'll want to ensure that the recordings that you make are
in the correct format. You can define parameters such as sample rate, file format,
compression used and whether mono or stereo and give them a name - the
"recording style".
For example, a user in the radio industry may wish to store all audio on their play-
out system in stereo at 384 kbit/sec using mpeg compression. The recording style
could be called "radio" and every time that "radio" is selected as the style, the
recording made would be fully compatible, without the need for setting up the
Courier each time.
When recording in the field you often only get one chance, so it is imperative that
you can rely on your recorder. Courier has a confidence monitor - it is able to
replay material recorded to disk whilst still recording. Once you are recording, all
other controls are disabled except record levels, so you can’t accidentally stop your
recording.
Courier is powered using standard 6V 8mm-camcorder batteries that are
extensively available world-wide. There is an audible warning when the battery is
running low and the battery can even be changed without interrupting the recording
process. Supplied with your Courier is a mains adapter/charger, which
simultaneously charges the battery and powers your machine. An optional cigar-
lighter adapter is available to operate the Courier and charge the battery when in a
car.
Two inputs are available for either a single stereo source, or two mono sources,
which can be at microphone or line level. Each input has a level control, which can
be used separately or ganged together - the record level control is recessed so that it
can’t easily be knocked. Phantom power at 48V can be supplied to both
microphones individually and a high pass filter, essential for eliminating low
frequency traffic noise, together with a limiter, can be switched in.
A clearly visible display details the recording level (there is a separate LED peak
level display) and time count-up whilst recording. It can also give an indication of
disk space remaining and battery condition.
