Note:
If the recording is started directly from the “
STOP
” mode, the Pre-record buffer will be off. If
during record the “
RECORD
” switch is pushed upwards again, a new file will be started
(seamless recording).
Each new recording will be given a file name made up of 8 digits. This file will be stored in the
working directory.
See “File naming and working directory” for details.
7.1.1 The Automatic Gain Control (A.G.C)
The AGC is not an audio limiter. It operates in the digital domain and allows the operator to make
recordings without under / over modulating when the audio levels are unpredictable.
It makes recording in the field easier and guarantees that a respectable level will be recorded.
Automatic adjustment systems are rarely “better” than the manual modes, but can be considered
“safer” in certain circumstances. The operating target level or average level to be recorded can be set
to either –6 dB or –12 dB in the “
SCREWDRIVER
” menu. It is also strongly recommended to switch
on the low cut filter when using the AGC for recordings in noisy environments (example: Street
noise).
7.2 Playback of a previous recording
The ARES-ML can play back files irrespective of the current compression mode selected. To
playback the last recorded file, press “
PLAY
” and the machine starts playback immediately. To stop
the playback, press the “
PLAY
” key again. To pause the playback, use the “
OK
” key.
If the recording was made with markers, during the playback, briefly press the “
RIGHT
” or “
LEFT
”
keys to jump to the next or previous marker position respectively.
To playback another file from the same working directory, use the “
UP
” or “
DOWN
” keys to scroll
through the recorded files available. Once “
PLAY
” is pressed, the new file will be played immediately.
During a playback of a file, the full 3 colour “
PLAY PROGRESS BAR
” corresponds to the total length
of the file.
When a new file has been selected for playback the “
TOTAL TIME
” counter will indicate its full length
and the “
PLAY TIME
” counter starts incrementing once the playback begins.
During playback, to “
REWIND
” press and hold the “
LEFT
” key, to go “
FORWARD
” press and hold the
“
RIGHT
” key.
7.2.1 Adjusting playback levels
The output volume level for the headphones and line output can be adjusted by the “
+ VOL -”
buttons
on the right side of the machine
in steps of 0.5 dB from -40 dB up to +1 dB. This value is also shown
on the display (see Record window description) and stored in the memory of the machine.
7.3 Storing settings in a template
Templates are used to store the settings for the ARES-ML. These templates contain input device,
levels, filter selection, Electret powering, type of compression, mono or stereo etc.
Input device manager
: 10 templates are available and each can store the name and characteristics
of different input devices such as different microphone capsules, line inputs and the gain settings,
powering and filters can be selected for each device.
Compression template
: 10 templates are available and each can be given a dedicated name and
can store the desired compression mode, sampling frequency, bit rate and the file extension desired.
To go to the programming position, jump to the paragraphs entitled “
MANAGER
” & “
SETUP MENU
”.
