ATTENTION: CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. POUR EVITER LES CHOCS ELECTRIQUES, INTRODUIRE LA LAME LA PLUS LARGE DE LA FICHE DANS LA BORNE CORRESPONDANTE DE LA PRISE ET POUSSER JUSQU' AU FOND. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. "WARNING" "TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. " SAFETY INSTRUCTIONS 1. Read Instructions - All the safety and operating instructions should be read before the appliance is operated. [. . . ] When recording in stereo, two (L and R) WAV files are created, while a single WAV file is created when recording in mono. A BWF file created is stored in the "bwff" folder which is created on a CFC/ATA (see the figure below). The FR-2 uses the "1 take - 1 file" system. With this system, each time you make recording, a new audio file is created on the card. Note that you cannot make additional recording or overwriting to an existing file. CFC or ATA BWFF *****. wav *****. wav *****. wav By connecting the FR-2 to your PC, you can transfer an audio file recorded by the FR-2 to the PC, and vice versa. Therefore, you can copy an audio file recorded by the FR-2 to a PC hard drive or export it to a computer application such as Digidesign Pro Tools. The table below shows the approximate recording time on a 1GB card (CFC or ATA). Note that actual recording time may be slightly different depending on card manufacturers.

Selecting the input source Set the [LINE/MIC] switch for each (L, R) channel appropriately according to the source (microphone or line) connected to the associated [ANALOG IN] (L/MONO or R) connector.

The cutoff frequency is 100 Hz and the filter slope is -12 dB/oct. The [HPF] switch, which selects ON or OFF of the high-pass filter, is provided for each channel. The filter is useful to eliminate the wind noise during location recording or unnecessary low frequency noise when recording a voice or sound.

FWD PLAY REC END ABS 0 49 FR-2 Field Memory Recorder (Chapter 5: Recording/playback) Limiter By using the limiter, the signal level is prevented from exceeding a certain level. In result, the signal level fluctuation is suppressed. Therefore, the limiter is useful when recording a sound whose level is unknown. You can activate the limiter for both L and R channels by setting the [LIMITER] switch to "ON". The FR-2 limiter uses the VCA (Voltage Controlled Amplifier) circuit. By default, the threshold is -2 dB under the 24-bit full-scale level (all bits: ON) and the compression ratio is 1:5. The limiter attack time is fixed to approximately 20 ms, while the release time is fixed to approximately 150 ms.

FWD PLAY R STOP Selecting the sampling frequency/quantization bit length You can select the desired sampling frequency ("FS " for short) and quantization bit length ("Bit" for short) for recording by using the [FS (kHz)] and [QUANTIZATION] switches on the top panel. You can select the FS from among 22. 05 kHz, 44. 1 kHz, 48 kHz, 88. 2 kHz, 96 kHz, 176. 4 kHz and 192 kHz, while you can select the Bit between 16 and 24 bit. The current FS and Bit settings are shown on the Home screen. See the available combination of FS and Bit settings in the table below. [. . . ] While transferring file data from the FR-2 to the PC, the [ACCESS] indicator on the FR-2 panel lights (or flashes). When completing data transfer, the [ACCESS] indicator turns off. <Note>: When file data is copied from the folder, the original file on the memory card remains. When file data is "moved" to a folder, the original file disappears from the card. 7) After transferring the file data, remove the USB cable from the PC. <Note>: To disconnect the FR-2 from the PC after exporting the file data, make sure that the [ACCESS] indicator is unlit, and follow the instructions of the Windows "Safely Remove Hardware" application. 8) Press the [HOME] key to exit the MENU mode. 99 FR-2 Field Memory Recorder (Chapter 7: Exporting audio files to a PC) Exporting audio data to a computer application (example) The following procedure example shows how to export FR-2 audio data to Digidesign Pro Tools for Windows.
