3. PRINCIPLE OF OPERATION
User Interface
Principle of operation
Status
The MINIR82 status is shown by means of the green or red "status" led's and the screen display. The
following status scenarios are possible:
•RECORD READY the Red LED is flashing, the MINIR82 is ready to start recording
•RECORDING the Red LED lights On steady, confirming that a recording is in progress.
•PLAYING the Green LED lights On steady, a take is being played
•PLAYER PAUSE the Green LED flashes, the Take being played is paused at current location.
•PLAYER STOP a Take is loaded ready to be played, no LED lights on nor flashes
Clipping LEDs
The "Left Channel" and "Right Channel" Led's shows two particular statuses that are either:
•Limiters: either the Left or the Right LED lights On independently when the Microphone Input signal
reaches a level of 2.5dB before clipping, thus activating the Limiter.
•Clipping: the Input signal is too high on the microphone A/D Converter, both Left and Right LED's
light On together
On screen Display and Keys
The main working page (Tracks Monitoring) displays the 8 Peak Meters.
The meter range starts at –72dBFs and goes up to 0dBFs in 1dB steps from –72dB up to –24dB
and in 0.5dB steps from –23.5dB up to 0dB.
A reference line at -9, -12, -18, or –20 dB can be displayed on screen (see configuration's menu)
The bottom line of the display shows the functions of the Keys. Conventionally, the UP and DOWN keys are
used to change the parameters, the Right key is used to "Select" and the Left Key to "Cancel".
A single Arrow symbol denotes that an action is achieved by briefly pushing the key.
A double Arrow symbol means that the key must be pushed longer to validate the action.

3.1.1 ARCHITECTURE - AUDIO PATH
The MINIR82 offers12 physical Input channels, up to 8 of these input channels can be used at the same
time. These 8 input channels are configured per pair:
•1, 2: Microphone input or AES 1
•3, 4: Line input or AES 2
•5, 6: AES 3
•7, 8: AES 4
The routing Matrix allows routing and mixing any input channel to any of the 10 tracks. The first 8 tracks are
dedicated for the hard disc (HD) and the 2 additional tracks for the Compact Flash card (CF).
The Monitoring can be configured by the user to listen any combination of these 10 tracks. However, the
display shows only the meters of the 8 hard disk tracks

3.3 PLAYER MODE
When a TAKE is loaded either from the [LAST TAKE] menu or from the [BROWSE FILE] menu, the MINIR82
switches to PLAYER mode and automatically reconfigure the system with the same parameters as set
during the recording of that particular Take; Routing - Monitoring etc.
The main screen of the Player is very similar as this of the Recorder. Due to space limitation the bottom line
does not always displays the action of the Keys; posted information's depend on the status such as Playing -
Paused or Stopped; however calling additional functionalities such as the [SOLO MONITORING], the
[HEADPHONE VOLUME] or the [CONTEXTUAL MENU] is made as when in Recorder mode.
While Stopped: when the Player is stopped, a pressure to the Left or the Right key calls a new screen
allowing a quick search of previous or next takes stored in the same folder ( such as the folder of the current
working days). The [BROWSE FILE] menu must be used to load a Take stored in a different folder.

4.5.2 ROUTING SETTING
SETUP > ROUTING SETTINGS > ROUTING TABLE
The routing, or channel assignement to the tracks, is done by means of a specific matrix as shown below:
ROUTING MATRIX
The round dot assigns the inputs channels to the tracks. Any combination is possible, thus any input channel
can be routed to any track or to multiple tacks and multiple channels can be routed on the same track
(mixing).
The figure above shows a 1x1 routing between inputs and tracks 1 to 4. Inputs 5 and 6 are routed to tracks
7 and 8. In addition, input channels are also individually routed to the tracks of the CF card.
Keys Short pressure Long pressure
LEFT Move the selection cursor to the Left Return to the previous menu
RIGHT Move the selection cursor to the Right Activate/Deactivate the assignment
UP Move the selection cursor upward
DOWN Move the selection cursor downward
NOTES: The configuration is automatically saved when leaving this menu
The un-assigned Tracks (no dot on the crossing) are automatically desactivated.
SETUP > ROUTING SETTINGS > MIXING LEVEL
The [MIXING LEVEL] menu defines the attenuation to be applied to each channel when summing (mixing)
multiple input channels onto the same track; the attenuation is computed to avoid a digital clipping. Four
possibilities are offered and the choice depends on the phase coincidence of the sources.
•NONE no attenuation at all
•ATT1.5 mainly used if the sources have no phase coincidence
•ATT3 recommanded for phase coincident sources such as sereo or M/S microphone
•ATT6 only used if the sources are absolutaly in phase
The table below summarizes the exact attenuations computed and applied according to the number of input
channels assigned to the same track.

SETUP > ROUTING SETTINGS > MIRRORING
When the [MIRRORING] function is activated, the routing and the eventual mixing level of the input channels
onto the hard disk tracks is identically replicated on the Compact Flash card. The tracks are recorded
simultaneously on the hard drive and on the CF card providing that the performances of the CF card permits.
When the Mirroring is activated, the two tracks of the CF card no longer appear in the routing matrix and are
replaced by the word MIRROR.
NOTE 1: Several series of tests with CF cards offering good performances helped to validate the
recording of up to 8 channels at 96kHz/24bit. If the performances of the CF card does not
allow mirroring, an alarm "CF" will flash on the screen. The recording on the CF card will be
aborted but will continue on the HD.
NOTE 2: If the storage capacity of the CF card is reached during the recording, the CF card will stop
recording but the recording will continue on the hard disk.
4.5.3 RECORD SETTINGS
SETUP > RECORD SETTINGS > BIT PER SAMPLE
This menu sets the sample's quantization (number of bits per sample) stored in WAVE files. Although the
A/D converters of the MINIR82 exclusively convert in 24 bits mode, the DSP can re-quantize the recorded
samples by the following values:
•24 bits: original value as quantified by the A/D converter
•16 bits Dithering: reduction to 16bits per sample with triangular dithering
•16 bits: reduction by truncation of the original quantization
SETUP > RECORD SETTINGS > SAMPLING FREQUENCY
This menu sets the sampling frequency. Choices are: 44.1, 48, 88.2, 96, 176.4 and 192 kHz.
If an AES input is assigned, the MINIR82 will automatically lock on sampling frequency of the incoming AES
signal, thus the selected sampling frequency will be overwritten. The sampling frequency of the incoming
AES signal can be checked in the [UNIT STATUS].
SETUP > RECORD SETTINGS > SAMPLING UP / DOWN
The sampling frequency can be set either at its nominal value or pulled Up or Down for the NTSC world;
when the sampling Up or Down is chosen, the nominal sampling frequency is either increased respectively
decreased by 0,1% ( or one per thousand). The symbol " %+ " or " %- " is then displayed on the upper right
corner of the main screen.
C Mode is a special "compensated" mode faking the pull Up/Down; the recording is performed at nominal
sampling rate and the stamped value indicates 48000 which is the true number of samples per second;
however the Time Code is compensated (or cheated) so that the Time is stamped as if the digitization was
done at 48048 (the Time Stamp is computed by counting the number of samples since midnight)

SETUP > RECORD SETTINGS > AUDIO SYNC MODE
Audio synchronization means locking the sampling frequency on a given signal, either internal or external.
The synchronization mode is shown in the Unit Status menu.
The different synchronization modes and the validity of the parameters are explained below:
INTERNAL
The MINIR82 locks on its internal clock generator, which generates all sampling frequencies (44.1, 48, 88.2,
96, 176.4 and 192 KHz). This generator is used only when no other clock is available.
•Sampling frequency: active
•Sampling up/down: active
•Bit per sample: active
Synchronisation on AES input:
The MINIR82 will automatically lock on the incoming AES clock of the channels 5-6
•Sampling frequency: inactive
•Sampling up/down: inactive
•Bit per sample: active
WCK IN
WCK IN must be selected to lock the MINIR82 on an external word clock applied to the SYNC IN connector.
This mode is overwritten when an input AES is routed.
•Sampling frequency: inactive
•Sampling up/down: inactive
•Bit per sample: active
VIDEO IN
VIDEO IN must be selected to lock the MINIR82 on an external clock derived from a video signal applied to
the SYNC IN connector. This mode accepts all video formats, including the bi and tri sync level systems.
This mode is overwritten when an input AES is routed.
•Sampling frequency: active
•Sampling up/down: inactive
•Bit per sample: active
SETUP > RECORD SETTINGS > FILE FORMAT
The recorded audio tracks can be stored in three different file formats:
•MONO
•STEREO
•POLYPHONIC
When MONO is selected, each track is recorded in a separate mono file.
When STEREO is selected, the system records each pair of tracks in a single stereo file. The pairs are
always 1+2, 3+4, 5+6 and 7+8.
If POLYPHONIC mode is selected, all active tracks are recorded in a single file. This mode requires to
enable the MIRRORING regardless of whether the Compact Flash card is present or not

SETUP > RECORD SETTINGS > PRE-RECORD TIME
The Pre-Record time can be set from zero up to 20 seconds. The selected value may not always be possible
due to the physical limitation of the built-in memory. The Pre-Record time depends on following factors:
•Number of Tracks being assigned
•Sampling frequency
•Sample Rate and Pull UP/ Pull DOWN correction
When the required pre-record time is not possible, the MINIR82 will perform on "best effort" basis to provide
with the maximum possible. The table below shows the maximum values of the pre-record time [seconds]:

4.5.4 INPUTS SETTINGS
SETUP > INPUTS SETTINGS > INPUTS SOURCE
This menu is used to select which of the analogue or the digital source of channels 1-2 and 3-4 is assigned
to the routing matrix; the selection is always made for a per pair of channels
•Input channels 1 & 2: MIC/LINE 1 & 2 or AES 1
•Input channels 3 & 4: LINE 3 & 4 or AES 2
SETUP > INPUTS SETTINGS > MIC LOW FREQ CUT
When channels 1-2 are configured as MIC/LINE INPUT, a low-pass filter can be activated for each channel
individually by this menu.
