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. [. . . ] 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. 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". 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. See the available combination of FS and Bit settings in the table below. While receiving a digital signal, the FR-2 automatically detects the FS and Bit from the receiving digital signal, which takes priority over the [FS (kHz)] and [QUANTIZATION] switch settings.

While stopped (or during playback), the FS and Bit recorded on the current file are shown. <Note>: During recording, you cannot change FS and Bit setting. If you change the [FS] select switch setting during recording, the switch setting becomes effective when recording stops. 50 FR-2 Field Memory Recorder (Chapter 5: Recording/playback) Selecting the track mode According to the situation, select the track mode (whether making recording in mono or stereo) using the [TRACK MODE] switch. The [TRACK MODE] switch setting is shown on the Home screen. MONO STEREO The FR-2 records only the analog "L" input channel signal to a single file. The FR-2 records the L and R analog stereo input signals to two individual files. <Note>: You cannot change the track mode during recording.

Pressing the [REC STBY] key again releases "input monitor". <Notes> · Adjust the recording level appropriately so that the level meter does not exceed "0 dB". To get the maximum signal-to-noise performance, set the recording level appropriately so that the meter indication does not exceed "0 dB" but goes up near to the "0 dB" at the loudest part of the input signal. The reference level is set to the "-20 dBFS" relative to digital full-scale. "20" on the meter is labeled in inverse video, showing that it is the reference position. You can set the unit to generate the error tone when the input amplifier clips due to over level by using the "Error tone" menu item on the Setup menu in the MENU mode. See "Setting error tone output condition" on page 87 for details. · The file name field shows realtime counter data which is running. During record standby, " " and " " are alternately flashing here.

Inserting a plug to the [PHONES] jack automatically disengages the internal speaker, and you can monitor the signals only via headphones. Pressing on the control knob raises it above the panel to permit level adjustment. Pressing the control again recesses the knob to avoid accidental setting changes. [. . . ] By opening "My computer" on the PC, a drive named "Removable disk" is added to the PC. The first time you connect the FR-2 to the PC, the disk driver is installed. 6) Open the removable disk drive newly added and select a desired audio file in the appropriate folder, and then copy it to the PC. When opening the removable disk drive newly added, all audio files stored to the memory card in the current drive is shown. 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.
