■A convenient recorder that
records 4-channels simultaneously
4-Channel Portable Recorder
Rｰ44
This 4-channel portable audio recorder uses SD cards. It can
record high quality 24-bit/192kHz audio with the convenience
of a built-in stereo microphone and speakers. You can get up to
four hours of continuous recording using four AA NmH batteries,
allowing video producers to concentrate on filming.
You need to know what to ask for to get the
sound you want. There is a way to get the mix
you want by asking for the channels you
require. PGM Out is the post-fader audio signal
which is mixed for PA balance and contains
effects along with the PA sound. The pre-fader
signal is closer to the original unaffected sound.
However, since the PGM Out audio signal is
post-fader, the levels are already mixed, but the
pre-fader audio signal requires you to mix the
audio yourself. Both have their advantages and
disadvantages, so the decision is yours.
What do you need?
If the audio cables you provide that connect the
output of the mixing console to your recorder
are XLR connectors, you must request balanced
analog outputs from the mixer.
Next, we'll talk about cable specifications. There
are various types of XLR connectors, which are
usually compatible with most mixing console
outputs. Sometimes the three connecting pins
are wired differently with some cables, so keep
this in mind (as shown on the right).
What to do about the levels?
As explained above, the audio level from the
PGM Out has already been adjusted, but be

Video Field Recorder
Fｰ1
This HDV/DV recorder has a 120GB removable hard drive. Aside
from recording the HDV/DV stereo audio, it can also record audio
from two separate channels simultaneously. The 16-bit/48kHz
sound quality is recorded in wav file format. With this unit alone,
you can record audio from the line out of a mixer, along with stereo
audio from the camera to achieve a good sound balance.
sure to check it during the rehearsal. The sound
engineer may be able to provide you with a
reference signal.
The F1 is ideal for recording events because it can record for
about 9 hours. Three power sources are available: AC adaptor,
external battery, or AA batteries.
With the V-mount kit you can use widely available batteries
to extend the operation time. If you use the down-conversion
capabilities on the camera to output DV, you can record HDV on
the tape as DV (PCM audio) on the hard drive. This enables you to
get 4-channel uncompressed linear PCM sound.
What is a Cannon (XLR) connector?
It is a 3-pin connector attached
to cables often used in venues.
The 3-pin design is usually wired
as follows; pin 2 is hot (+), pin 3
is cold (-), and pin 1 is shielded.
In some cases, pin 2 and 3 may

be wired in reverse. Audio can still
be heard with this wiring scheme, however, you may
experience a loss of signal near the center position of a
stereo recording. Nowadays, this can be corrected with
nonlinear software or an audio editing application that
allows phase reversal.
