September 2006 En. ENGLISH Contents FlashMic Features Your FlashMic combines a professional-quality, omni-directional condenser microphone with an internal digital audio recorder in a single self-contained, self-powered unit. An extremely simple set of controls make it suitable for completely non-technical users; alternatively, more experienced recordists can access a wide range of additional functionality through menu-based pages on the FlashMic’s LCD display. Retrieval of recordings is via the FlashMic’s USB port; the stored sound files are transferred to a computer as .wav files in either linear or compressed (MPEG 2 Layer 1) formats. Transfer is either by using the supplied FlashMic Manager software, or by standard dragand-drop file handling. Think of your FlashMic as the audio equivalent of a digital camera. Just as you use a digital camera to quickly and conveniently record high-quality visual images for subsequent transfer to a computer, so you can use FlashMic to capture sound. Just as pictures can be subsequently edited, stored, e-mailed, deleted, or whatever – so you can now manipulate recorded audio in the same ways. The FlashMic is ideal for use by journalists and reporters for news-gathering and interviews, by business organisations, public institutions – any situation where a quick and convenient method of voice recording is required. ENGLISH Some of the main features of the FlashMic are as follows: • Linear or compressed (using MPEG 1 Layer 2 compression) digital audio recordings as .wav files. • Recording time up to 18hrs (file format and sample rate dependent). • Built-in headphone amplifier for monitoring, with adjustable level. • Uses 2 x AA cells – either alkaline or rechargeable. • Modes of operation to suit both technical and non-technical users. • Adjustable pre-record buffer of up to 10 seconds. • Rapid file transfer via USB to PC or Mac. • 9 internal presets for storing different FlashMic configurations. • Adjustable recording level or fixed AGC mode, with bargraph display. • Remaining Time display. • Replay of last or an earlier recording via monitor output. • Markers (cue points) can be added to recordings in both Record and Playback. • File recovery system allowing recovery of most audio data in the event of power loss or other failure.

Either 1.5v alkaline or 1.2v NiMH (nickel metal hydride) rechargeable batteries may be used. Batteries of at least 1500mAh capacity are recommended. ! Do not use zinc chloride batteries. Inserting Batteries ENGLISH Hold the FlashMic in one hand and unscrew the rear section (the section with the display and operating controls) with the other. Slide the rear section back as far as it will go. Open the hinged plastic battery compartment cover. Insert the two batteries oriented as shown on the compartment cover. ! The two batteries must point the same way. ! Always change both batteries at the same time, and always use two batteries of the same brand and type. NEVER mix alkaline and rechargeable batteries. Close the cover, push the rear section back over the compartment, and screw up tight. Note: If changing alkaline batteries, dispose of the old ones in a responsible manner – always observe local environmental guidelines. Battery Management Battery life will be maximised if the FlashMic is switched off when not in use, as the power consumed in IDLE mode is virtually the same as in REC mode. The internal clock settings are protected within FlashMic for approximately 1 minute after the batteries are removed. Recorded sound files and configuration settings are not affected by battery removal. Remove any batteries from the FlashMic if it is to be unused for an extended period (more than a month). Battery Status Indicator A 4-segment battery status indicator is provided on the LCD display. The number of segments displayed is proportional to the battery power remaining. The rate of change of the display can be altered (via the menu system or via the FlashMic Manager software) to reflect the different discharge characteristics of alkaline or rechargeable batteries. The display backlight, the record LED on the FlashMic base and the battery indicator will all flash when the remaining battery life approaches zero. If the FlashMic is recording when the batteries are nearly exhausted, the recording will be stopped after the flashing warning. En. Using the FlashMic Jogswitch Description Many of the FlashMic’s operating functions are accessed via the jogswitch on the bottom panel. These include power on/off, navigation through the various internal menus, adjustment of levels, and track selection for replay. Operation of the jogswitch for each specific FlashMic function is described in detail in the section of the manual covering the function. However, because the jogswitch has several physical movements associated with it, an overview is given here. The jogswitch is a small wheel protruding from the base of the FlashMic. It is effectively three momentary-acting pushbuttons in one; it can be pressed inwards (from its rest position), or rotated in either direction. The actions are all spring-loaded so that the jogswitch always returns to its rest position. Each of the three possible movements can be either ‘long’ or ‘short’, giving a total of six possible actions. The FlashMic’s firmware determines a ‘long’ press to be one of greater than 2 seconds. duration, and as ‘short’ press to be one of less than 2 seconds. ENGLISH The diagram below summarises the possible movements. Elsewhere in this manual, the following notations are used to denote the various types of jogswitch action. It is assumed that the FlashMic is orientated with the LCD display facing the user. NOTATION ACTION SHORT PRESS Press the centre protrusion inwards and release LONG PRESS Press the centre protrusion inwards for a least 2 seconds SHORT DOWN TURN Move the wheel downwards and release LONG DOWN TURN Move the wheel downwards and hold for at least 2 seconds SHORT UP TURN Move the wheel upwards and release LONG UP TURN Move the wheel upwards and hold for at least 2 seconds En. Switching The FlashMic On The FlashMic is switched on by a SHORT PRESS on the jogswitch, and switched off by a LONG PRESS until the text OFF appears in the display. The FlashMic will turn off when the jogswitch is released. Note that it is not possible to turn the FlashMic off while it is connected to a computer via its USB cable. On switching the FlashMic on, the LCD panel displays in sequence: DRM85 ê Firmware version ê Microphone name ê Active preset. After this sequence, the FlashMic is in its standby state – referred to in this manual as IDLE mode - and the displays are as shown below. 03:14:35 FlashMic IDLE Mode Displays In IDLE mode – i.e. when the FlashMic is powered but not otherwise being operated – the main display alternates between the number of the last recording (TRKnnn - recorded files within the FlashMic are referred to as ‘tracks’) and the remaining recording time. An exception to this is when no recordings have been made since the FlashMic was last reconfigured, when the message NOFILE appears instead of TRKnnn. The FlashMic is fitted with an internal calendar/clock. Before using the FlashMic for the first time it is recommended that this is set correctly, as this information is included in the audio file header as their time/date. See Clock Set Menu, page 22 for details of how to do this. En. ENGLISH Note that the factory default microphone name is DRM_85 and the factory default preset is PSET_1. Making a Recording ! The file format created within the FlashMic includes a record of the date and time at which the recording was made, together with textual information – entered via FlashMic Manager software – to aid later identification of recordings. Nevertheless, it is good recording practice to keep a separate written or electronic recording log during a recording session in the field, as many similar-sounding files may often be created. Keeping such a log is recommended. It will frequently ease the task of identifying your recordings after they have been transferred into a computer for further editing. To initiate a new recording, press the red REC button (G). The REC flag in the display and the REC LED on the FlashMic’s rear panel both illuminate. ! ENGLISH The record LED can be turned off, if for example, the FlashMic is in camera shot. To do this, press and hold the PLAY button while the FlashMic is in REC Mode; the display will show LEDOFF. The LED can be re-enabled by repeating this action while still in REC Mode. Note that the LED will always illuminate initially when REC Mode is selected. The bargraph meter in the display provides an indication of the audio level, in both Idle mode and Record mode. The main display indicates the remaining recording time, and counts down. When there are 10mins. of record time remaining, the display backlight, the record LED on the FlashMic base and the REC flag in the display will all flash. The FlashMic will stop recording when there is 1min. of recording time remaining; this is to allow for data error correction. To stop the recording, press the M/STOP button (M). The text SAVING appears in the display, and after a brief pause, the IDLE display resumes, with the track number being indicated. 03:24:04 SAVING Rec Recording Display Saving Recorded Track Factory settings: Settings of recording format, record level, etc., will generally be made via the system of configuration files and presets within the FlashMic Manager software. However, the FlashMic comes with a set of factory parameters enabling it to be used “out of the box”, without any recourse to FlashMic Manager. See Using the Default Configuration, page 26 for a list of these parameter values. PreRecord Buffer (Introduction) In a busy journalistic schedule, it is sometimes difficult - or impossible - to get to the record button quickly enough. The result is a recording that starts a few seconds after the vital bit of information that was needed. The FlashMic incorporates a pre-record buffer of up to 10 seconds (adjustable), which avoids this situation. When the recording is replayed, it will be found that it begins with the few seconds of audio captured immediately prior to the REC button being pressed. See PreRecord Buffer, page 34 for more details. En.10 Record Lock The FlashMic is equipped with a REC LOCK function to prevent the accidental cancelling of REC mode during a recording. Once in REC mode, press the REC button a second time, holding it down for at least 2 seconds, until the LCD screen displays the text LOCKED. Pressing the M/STOP button will now have no effect (other than to display the text LOCKED). To disable REC LOCK mode, press and hold the REC button until the LOCKED display changes to UNLOCK. Now the recording can be stopped in the normal manner by pressing M/STOP. UNLOCK Rec ENGLISH LOCKED Rec REC LOCKED/UNLOCK Displays Monitoring A pair of headphones may be connected to the FlashMic for monitoring purposes. Headphones of 32 ohms impedance or higher should be used. Connect the headphones via the 3.5mm 3-pole jack marked PHONES on the FlashMic bottom panel. The mono signal from the FlashMic will be heard in both earpieces. Headphone monitoring of live audio is active in both IDLE and REC modes. The monitor output may be used to drive external equipment for monitoring or recording if desired. The monitor level is adjusted with the jogswitch; a SHORT PRESS shows the text PHONnn on the LCD display, where nn = the current level. (The units are arbitrary; 00 = off, 50 = max.) A SHORT UP TURN or DOWN TURN will respectively increase or decrease the monitor level. Note that the monitor level always resets to a factory preset level when the FlashMic is switched on. The level can be adjusted during REC, PLAY or IDLE modes. The LCD display will return automatically to the REC or IDLE displays after a timeout period of approx. 2 seconds. Adjusting Record Level ! Adjustment of Record level is only possible if the FlashMic has been set (via the FlashMic Manager software) to permit configuration changes by the user. See the section on FlashMic Manager for more information. The recording level is adjusted with the jogswitch. A SHORT UP TURN or DOWN TURN while in REC mode displays the text RVOLnn, where nn = the current level. (Unlike monitor level, the units are not arbitrary, being increments of approximately 1dB; 01 = min, 40 = max.) Further SHORT UP or DOWN TURNS will nudge the record level up or down. When the record level is reduced to minimum, the AGC system is selected and the display shows RV AGC. In this mode, FlashMic automatically adjusts recording level according to the sound level. In most situations, this ensures that a recording of usable level will be made, but as with all automatic gain systems, a degree of background noise “pumping” may be audible on the recording. It is also possible to adjust the FlashMic’s recording level from IDLE mode, using the menu system. See FlashMic Menu System, page 16. Note that the record level always resets to the last value used when the FlashMic is switched on, and not to the value set as part of the preset by FlashMic Manager. (See section on FlashMic Manager for more information on presets.) RVOL35 RV AGC Rec Rec Setting Recording Levels En.11 Replaying Tracks A recorded track may be replayed for auditioning purposes. To replay the last track recorded, press the PLAY button (H). The PLAY flag on the LCD display illuminates. After a brief pause, the display shows the elapsed time of the track. The bargraph meter will show the level of the track being replayed. The playback may be monitored via the PHONES connector. At the end of the track, the FlashMic will resume IDLE mode. Pressing the M/STOP button during replay will also return the FlashMic to IDLE mode. To pause playback during play, press PLAY again. The LCD display will show PAUSE. Play can be resumed by pressing PLAY again, or stop mode can be entered by pressing ‘MENU/STOP. A LONG UP TURN on the jogswitch will “fast-forward” the track (FFW mode), to enable a particular section of the track to be located. Similarly, a LONG DOWN TURN “rewinds” the track (REW mode). The time display continues to show the track time during these ‘fast’ modes. Note, if marker points have been added to the track, jogswitch turns will instead ‘jump’ the replay to the next or previous marker point (depending on jogswitch direction). (See the following section on ‘Markers’ for more information.) ENGLISH To select and replay a track other than the last recorded, decrement the track number with SHORT DOWN TURNs on the jogswitch. (A LONG DOWN TURN will decrement faster.) UP TURNs will similarly increment the track number. When the required track number is displayed, press the PLAY button to replay the track. It is also possible to select a different track while remaining in PLAY mode; SHORT TURNs of the jogswitch will skip to the next or previous track, depending on the direction of rotation. Be careful not to make LONG TURNs, as the FlashMic will instead enter FFW or REW mode, as described above. TRK005 00:00:01 Play Select Track Display Track Replay Display Markers It is often useful to mark one (or more) points in a recording for ease of reference during later production and editing. You can add markers to FlashMic recordings in both REC and PLAYBACK modes.. The markers are ‘data flags’, which are embedded in the sound file at the appropriate point. They will appear as onscreen markers when the downloaded sound files are later loaded into a sound editing package. The markers are written to the sound file with both linear and compressed recording formats. FlashMic markers are recognised by a number of professional editing applications, including Cool Edit Pro, Adobe Audition, Sound Forge V4 and above. Note however, that editors can currently only read markers in sound files recorded using the linear recording modes. A marker is added whilst recording or during playback by a short press on the REC button. (Note that a long press activates the REC LOCK function in REC mode). The LCD display briefly displays MARKED. As the marker is purely a data flag within the sound file, no further indication of its presence will be apparent until the resulting file is loaded into an editor (although the marker points can be used as locators during playback). Deleting a Track If an erroneous or otherwise unwanted or unusable recording is made, it may be deleted from the FlashMic’s memory to save memory space. Deletion of tracks is performed via the FlashMic menu system. See Delete Menu, page 21 for full details on how to delete a track. En.12 File Transfer Typically, you will use your FlashMic ‘in the field’ to capture a number of different recordings. The resulting sound files will need to be downloaded from the FlashMic into a computer at some point for further evaluation, editing, deletion, or other treatment before they can be broadcast or otherwise made useful. In many organisations, the process of file transfer may be performed by someone other than the person who made the recordings. It is possible that a FlashMic may have been used by more than one recordist. Or it may happen that one recordist may use more than one FlashMic during a day of field recording. Thus is it important that any log that has been kept during the recording should be referenced during the transfer process so that files can be correctly identified and attributed. • Via the FlashMic Manager software supplied with FlashMic. • Direct transfer. Transfer Using FlashMic Manager This assumes FlashMic Manager has already been installed on a computer. See section Installing FlashMic Manager, page 23 if this is not the case. • First determine the location in the computer’s directory structure where the sound files should be transferred to. This may necessitate creating and naming new folders for the purpose. • Open the FlashMic Manager application. (Note the window which opens is not maximisable.) • Switch the microphone on. • Connect the FlashMic to a spare USB port on the computer, using the cable supplied. • The FlashMic LCD display will show USB, and the large red indicator in the FlashMic Manager window will turn green. There should also be some audible and/or visual confirmation on the computer that the FlashMic has been ‘recognised’. (Exactly what form this confirmation takes may vary slightly from computer to computer. Ignore any window called DRM85 that may open.) • In the area USB Connection, click the button Download Audio Data from DRM… The Transfer Audio Files dialogue box opens. • The tick boxes wav and mp2 allow the file extensions of any selected MPEG audio files to be changed. This only applies to MPEG recordings and not Linear recordings. En.13 ENGLISH There are two methods for transferring sound files from FlashMic to a computer. ENGLISH • The sound files in the FlashMic will be listed. Select those to be transferred by highlighting them with a single click. (Normal Windows/MAC conventions re multiple file selection apply.) • Click the Transfer… button. The Browse For Folder dialogue box opens. • Navigate to the folder into which the sound files are to be transferred. Click OK. • The file(s) are transferred. Depending on the number and length of sound recordings, and the spec of the computer, this may take from a few seconds to some minutes, during which time a progress indication is provided. When the files have been transferred successfully, a confirmation box appears. Dismiss this, and the transfer is complete. • Unmount the FlashMic. This action is performed by double-clicking the USB device icon in the status bar. This will open the Safely Remove Hardware dialogue box, in which external hardware connected to the PC’s USB ports will be listed. Select the DRM-85 by clicking on it, then click STOP. This step will ensure that no data is lost by simply disconnecting the mic. • It is now safe to disconnect the FlashMic. After disconnection, it can be switched off. Direct Transfer to a Computer As the FlashMic is a generic USB mass storage device, files can be transferred from it to a Mac or PC in the same way as from any other USB mass storage device. ! Do not attempt to format the FlashMic from Mac or PC as the internal file system will be corrupted and any recordings will be lost. Do not use the Chkdsk command from a PC as this may corrupt the FlashMic file system. Note the example given below applies to a PC running Windows™ XP. Other operating systems differ slightly, if you are unsure about this procedure, please consult your HHB dealer. • Switch the microphone on. • Connect the FlashMic to a spare USB port on the PC, using the cable supplied. The FlashMic’s display will show USB. You can audition the sound files recorded in the FlashMic before transferring them, if wished. To do so: • If a “DRM-85 (d:)” window opens (d = drive letter, will vary with PC) listing options for playing music files, you can select any audio file application offered (such as Windows™ Media Player) to audition the sound files within the FlashMic. The options available will depend on which software applications are installed on the PC. • If the drive folder above does not open, you can still audition the files by opening any audio application available on the PC, and selecting File>Open. Then navigate first to the DRM-85 device, which will be listed among the drives, then to the AUDIO folder within it. The sound files are all in this folder. If you do not wish to audition the files first, or have already done so, perform the transfer as follows: • First determine the location in the PC’s directory structure that the files should be transferred to. This may necessitate creating and naming new folders for the purpose. • Using Windows™ Explorer, navigate to the DRM-85 drive in the ‘Folders’ pane, and open the folder called ‘AUDIO’. The recorded sound files will be listed in the main pane. Do not delete any files in any of the other folders. En.14 Drag-and-drop the required sound files to their new location in the normal way. • Unmount the FlashMic. This action is performed by double-clicking the USB This will open the Safely Remove Hardware device icon in the status bar. dialogue box, in which external hardware connected to the PC’s USB ports will be listed. Select USB Mass Storage Device by clicking on it, then click STOP. Select the DRM-85 and click OK. This step will ensure that no data is lost by simply disconnecting the mic. • It is now safe to disconnect the FlashMic. After disconnection, it can be switched off. Connecting a FlashMic with low batteries to a computer. It is generally recommended that the FlashMic should not be connected to a computer if the batteries are running low. If the batteries do go flat during data transfer, the FlashMic will continue to perform the transfer, as it will also be powered via the USB connection. However, in this condition data loss may occur if the USB cable is unplugged without the FlashMic first being unmounted from the computer. Therefore unmounting the FlashMic (as described in the transfer procedures above) is recommended at all times, but is essential if the batteries are low. En.15 ENGLISH • FlashMic Menu System The FlashMic’s menu system allows you to adjust internal settings and select various options to suit your specific recording needs. Basic recording, playback and file transfer do not require use of the menu system. Note that some of the menus will only be available to the user if access to them was enabled in the FlashMic Manager software at the time of configuration file definition. These menus are clearly indicated in the descriptions that follow and are marked with an asterisk (*) in the table below. Please see the manual section on FlashMic Manager for more information about configuration files and enabling or disabling user access. Using the Menus The menu system is entered by pressing the M/STOP button while the FlashMic is in IDLE mode. The word MENU appears in the display. ENGLISH Note that pressing M/STOP while the FlashMic is in REC or PLAY modes cancels REC or PLAY. MENU Entering the Menu System This is the ‘header’ of the menu option list. A SHORT DOWN TURN of the jogswitch will now bring up the first of the menus, PRESET. Subsequent SHORT DOWN TURNs bring up the others in turn. When the menu that you want to check or modify is reached, it may be selected by a SHORT PRESS of the jogswitch. The menu options are: MENU DISPLAY USE Preset Menu PRESET Allows selection of a different configuration preset *Recording Mode Menu R MODE Allows selection of audio file format *Recording Level Menu RECLEV Adjustment of recording level *Hi-pass Filter Menu HIPASS Hi-pass filter in/out *Battery Type Menu BATTYP Set for battery type in use Delete Menu DELTRK Deletes selected recording Clock Set Menu TIMDAT Sets internal calendar and clock Pressing M/STOP a second time (from anywhere within the menu structure) will return the FlashMic to IDLE mode. A SHORT PRESS on the jogswitch from within a menu option (i.e., after a menu option has been selected) returns the FlashMic to the opening screen of that menu option. The display will briefly show OK to confirm that the required change has been made. En.16 Preset Menu The Preset Menu allows the user to select which preset from the FlashMic’s current configuration file is to be used. The FlashMic’s configuration file can have up to 9 presets. The configuration file is loaded into the FlashMic from a computer, using the supplied FlashMic Manager software. Each preset determines the value of various FlashMic parameters, including recording level and mode, pre-record buffer duration and the file name. (The file name will appear in the header of the audio files.) The parameters are all defined within FlashMic Manager; see Configuration Files and Presets, page 26 for a full description. ENGLISH To enter the Preset Menu, enter MENU mode by pressing the M/STOP button, and then make one SHORT DOWN TURN of the jogswitch. The display will show PRESET. Select this with a SHORT PRESS, and the name of the currently selected preset will be displayed. To select a different preset, make SHORT UP or DOWN TURNs of the jogswitch. The display will show the names of the alternative presets, as they were defined in FlashMic Manager. When the name of the required preset is displayed, a SHORT PRESS on the jogswitch will select it and load it into the FlashMic. The display will then show OK to confirm. PRESET Preset Menu Display Note that not all 9 presets available in a configuration file need to be defined in FlashMic Manager. Those not defined will be displayed as PSET N, where N is a number between 1 and 9, as PSET N is the default preset name used in FlashMic Manager. (However, note that PSET N will still be displayed for a preset that has been defined if the default name is not altered!) If selection of an undefined preset is attempted, the message EMPTY is displayed, indicating that this preset location cannot be used. PSET 1 EMPTY Preset Name Preset Empty Note that when the FlashMic is first used “out of the box”, all nine presets are empty. En.17 Recording Mode Menu This menu will not be available if ‘Enable Configuration changes in DRM’ was set to ‘No’ when the configuration file was defined in FlashMic Manager. The Recording Mode menu permits selection of an alternative digital recording format to that determined by the currently selected preset. A total of six recording formats are available within FlashMic; two file formats at each of three sample rates. The formats are: FILE TYPE SAMPLE RATE DISPLAY MAXIMUM RECORDING TIME ENGLISH BWF files (uncompressed) 48kHz LIN48K 3hr BWF files (uncompressed) 44.1kHz LIN44K 3hr 15min BWF files (uncompressed) 32kHz LIN32K 4hr 30min MPEG1 (Layer 2) files 48kHz MP48K 12hr 15min MPEG1 (Layer 2) files 44.1kHz MP44K 14hr 40min MPEG1 (Layer 2) files 32kHz MP32K 18hr 25min The choice of recording mode will usually be determined by the onward programme production chain. To enter the Recording Mode Menu, enter MENU mode by pressing the M/STOP button, and then make SHORT DOWN TURNs of the jogswitch until the display shows R MODE. Select this with a SHORT PRESS, and the display will show the name of the currently selected recording mode, as listed above. To select a different recording mode, make SHORT UP or DOWN TURNs. The display will show the names of the alternative modes. When the required recording mode is displayed, a SHORT PRESS on the jogswitch will select it. The display will then show OK to confirm. R MODE Record Mode Menu Display The recording mode selected will be that used for subsequent recordings until a different recording mode or preset is selected. Note that any recordings already in the FlashMic’s memory will remain at whatever mode was applicable when they were made. En.18 Recording Level Menu This menu will not be available if ‘Enable Configuration changes in DRM’ was set to ‘No’ when the configuration file was defined in FlashMic Manager. The audio level used during recording will be that defined within FlashMic Manager for the preset being used. The Recording Level menu permits this level to be altered. To enter the Recording Level Menu, enter MENU mode by pressing the M/STOP button, and then make SHORT DOWN TURNs of the jogswitch until the display shows RECLEV. RECLEV Select this with a SHORT PRESS, and the display shows either RVOLnn - where nn = the current level – or RV AGC if automatic adjustment of recording level was defined for the current preset. The recording level can now be adjusted with SHORT UP or DOWN TURNS. A SHORT PRESS selects the new level. RVOL34 Record Level Setting The units used are in dBs; 01 = min, 40 = max. When the record level is reduced to ‘zero’, the AGC system is selected. In this mode, FlashMic automatically adjusts recording level according to the sound level. In most situations, this ensures that a recording of usable level will be made, but as with all automatic gain systems, a degree of background noise “pumping” may be audible on the recording. RV AGC Record Level Set To AGC It is also possible to adjust the FlashMic’s recording level whilst recording. See Adjusting Record Level on page 11. Note that the record level always resets to the last value used when the FlashMic is switched on, and not to the value set as part of the preset. En.19 ENGLISH Record Level Menu Display Hi-pass Filter Menu This menu will not be available if ‘Enable Configuration changes in DRM’ was set to ‘No’ when the configuration file was defined in FlashMic Manager. The FlashMic’s analogue circuitry includes a hi-pass filter, to assist in the rejection of extraneous low-frequency background noises, such as air-conditioning noise or traffic rumble. The filter has a slope of 12dB/oct. and a turnover frequency of 100Hz. The filter is set to be in or out of circuit in the FlashMic Manager software for each preset, and is loaded into the FlashMic with the configuration file. However, the filter may be switched in and out of the recording chain via the menus. To enter the Hi-pass filter Menu, enter MENU mode by pressing the M/STOP button, and then make SHORT DOWN TURNs of the jogswitch until the display shows HIPASS. HIPASS ENGLISH Hi-pass Filter Menu Display Select this with a SHORT PRESS, and the display shows either HP ON or HP OFF. The filter can be switched in or out with SHORT TURNs of the jogswitch. A SHORT PRESS selects the setting. The display will then show OK to confirm. Battery Type Menu This menu will not be available if ‘Enable Configuration changes in DRM’ was set to ‘No’ when the configuration file was defined in FlashMic Manager. The FlashMic may be powered by rechargeable or alkaline batteries. The two types of battery have different discharge characteristics, and for the battery status symbol in the LCD display to reflect the battery’s remaining charge as accurately as possible, it is necessary to set the battery type menu parameter to match the batteries being used. The battery type is set in FlashMic Manager as a ‘global’ setting, which is applicable to all presets in one configuration file, and is not selectable to the different types for different presets. The setting may be overridden via the Battery Type Menu. To enter the Battery Type Menu, enter MENU mode by pressing the M/STOP button, and then make SHORT DOWN TURNs of the jogswitch until the display shows BATTYP. Select this with a SHORT PRESS, and the display shows either ALKLIN (alkaline) or RECBLE (rechargeable). The battery type can be changed with SHORT TURNs of the jogswitch. A SHORT PRESS selects the setting. The display will then show OK to confirm. BATTYP Battery Type Menu Display En.20 Delete Menu It is often desirable to delete unwanted recordings (tracks) from the FlashMic’s memory, particularly if they have been made erroneously or are otherwise unusable. The Delete Menu permits the user to do this. Note that any track deleted in this way is deleted permanently and irrecoverably. As tracks are only referred to by their track number on the FlashMic’s LCD display, before deleting a track always ensure you know which one you are trying to delete. The importance of maintaining an accurate recording log is again emphasised. If you have any doubt about the track number, replay it first to ensure you have the correct one. To enter the Delete Menu, enter Menu mode by pressing the M/STOP button, and then make SHORT DOWN TURNs of the jogswitch until the display shows DELTRK. ENGLISH DELTRK Delete Track Menu Select this with a SHORT PRESS, and the display shows the currently selected track number, which will normally be that of the last track recorded. TRK005 Select Track for Deletion If it is required to delete a different track, SHORT TURNs of the jogswitch will alter the track number either up or down. When the number of the correct track is displayed, a SHORT PRESS selects it. The text SURE N is now displayed. If you are sure you have selected the correct track, a SHORT DOWN TURN will change the display to SURE Y. SURE N SURE Y Cancel Track Deletion Confirm Track Deletion Another SHORT PRESS will now delete the track. Note that the track numbers of subsequent recordings are not altered. The display will then show OK to confirm. If the jogswitch is pressed in while SURE N is displayed, nothing is deleted, and the FlashMic returns to the head of the menu option, with DELTRK being displayed. En.21 Clock Set Menu The FlashMic contains a real-time calendar/clock, which allows a date and time ‘stamp’ to be embedded in the audio file headers. This is a great aid to later accurate identification of what may be many similar-sounding recordings made in the field. The clock runs continuously whilst batteries are fitted. It continues to run for approx. 1 minute after the batteries are removed, allowing time for a change of batteries. If the batteries are removed for a longer period, or before the FlashMic is used for the first time, the clock will need to be set to the correct date and time of day. Note that the FlashMic is perfectly usable without the clock being set accurately; the only consequence is that the file date/time information will be incorrect (though intervals between file creation times will be accurate). To enter the Clock Set Menu, enter MENU mode by pressing the M/STOP button, and then make SHORT DOWN TURNs of the jogswitch until the display shows TIMDAT. ENGLISH TIMDAT Clock Set Menu Display Select this with a SHORT PRESS, and the display shows Y yyyy, where yyyy is the year. This can be altered up or down with SHORT TURNs of the jogswitch. A SHORT PRESS selects the setting, and the display will now show in turn MON mm, where mm is the number of the month of the year; DAY dd, where dd is the day of the month; HH hh, where hh is the hour of the day (note that FlashMic uses a 24-hr. clock); MM mm for minutes, and SEC ss for seconds. Each of these can be altered in the same way as the year. The full sequence is show below. TIMDAT ê Y 2006 ê MON 04 ê DAY 06 ê HH 23 ê MM 00 ê SS 25 Set Year Set Month Set Day Set Hour Set Minutes Set Seconds After setting all the date and time parameters, the LCD display returns to the opening TIMDAT screen after briefly displaying OK; the menu system can then either be exited by pressing M/STOP, or another menu option can be selected with the jogswitch. En.22 FlashMic Manager FlashMic Manager is the software application supplied with FlashMic. The CD-ROM that came supplied contains both PC and Mac versions. While it is perfectly possible to use FlashMic without using FlashMic Manager, you will not be using it to its full effectiveness, and will not be accessing the full range of features and functions that FlashMic offers. • You will be able to alter the internal configuration of your FlashMic, to determine which file formats and sample rates are used, and to change other FlashMic parameters. • You will be able to change the default filename prefixes to something more meaningful to the particular job, adding, for example, a reporter’s name. • FlashMic Manager provides a very simple method of downloading recorded files to the computer. The installation instructions given assume that the user is familiar with basic Windows™/ Mac™ operations for file handling, navigation, etc. If you are unsure how to install the software, please consult your organisation’s IT department, or your HHB dealer.

FlashMic Manager Updates As a responsible manufacturer, HHB adopts a policy of continuous product development. As with all software-based products, it may be desirable from time to time to update the FlashMic Manager software with a more recent version. You can contact your HHB dealer or distributor, or visit the FlashMic website at http://www.flashmic.info for details of software updates. The current version will be displayed on the website along with details of how to download new software. Always be sure to delete any existing version of FlashMic Manager before installing a later version. This can be done by simply moving the single file FlashMicManager.exe to the Recycle Bin (PC) or Trash (Mac) En.24 Using FlashMic Manager ENGLISH The user interface of FlashMic Manager opens as shown below: FlashMic Interface Running on a PC FlashMic Interface Running on a Mac En.25 Configuration Files and Presets Before you start exploring the features of FlashMic Manager, it is important to understand some basic terminology and the concepts behind the use of presets. Various parameters of the FlashMic’s operation can be changed with FlashMic Manager. A set of parameters is called a preset, and the FlashMic can hold up to 9 presets at any time. The FlashMic user can select whichever is appropriate for the recording application using the menus. A set of 9 presets is saved as a configuration file within the computer, and you may create and name as many configuration files as you need. Configuration files are saved with a .cfg filename extension. The entire configuration file will then be uploaded into the FlashMic, giving it its 9 presets. The FlashMic parameters which can be defined in a preset by FlashMic Manager are the following: ENGLISH PARAMETER VALUES USER ALTERABLE* Preset Name 6-character text string No Record Mode File type & sample rate Yes Pre-record Buffer 0 to 10 seconds. No Record Level 8 steps from 5dB to 40dB Yes High-pass Filter In/Out Yes Backlight 3 options No Filename 31-character text string No Battery Display Characteristic Alkaline or rechargeable Yes * Parameters marked ‘Yes’ can be subsequently changed within the FlashMic by the user, provided that Configuration Changes were enabled in FlashMic Manager at the time of configuration file creation. Using the Default Configuration The first time FlashMic Manager is run, a file Defaults.cfg will be created. It will be found in the same folder containing the FlashMic Manager executable file (FlashMicManager. exe). This file differs from other *.cfg files in that its purpose is to provide a convenient set of default parameter values to aid the user in setting up his/her own personalised default configuration file. The parameter values provided by this default are: PARAMETER En.26 VALUES Record Mode Linear, 48kHz sample rate Pre-record Buffer Off Record Level AGC on High-pass Filter On Backlight Energy saving mode Filename TRACK Battery Display Characteristic Alkaline These are the settings that will be found in the FlashMic when used for the first time “out of the box”. ENGLISH To see these parameters displayed in FlashMic Manager, click File>New (or hit CTRL+N). This will remove the greyed-out fields ready for data entry. Then click Presets>Set Default Values (or hit CTL + D). This loads the parameter values listed above into the data fields for the currently selected Preset number, as shown in the Select Preset box (in this instance, 1). The FlashMic Manager window should now look like this: Note that it is possible to modify Defaults.cfg to suit the requirements of your own organisation (for example to include your company name). See Creating a Personalised Defaults File, page 33. FlashMic Manager Window - Features Preset Information Using the default parameter set loaded previously as an example (PSET_1), examine the various items of information now displayed in the window. Items marked ‡ are those uploaded to the FlashMic as part of the preset. Current Config file: The filename displayed here will be that of the currently loaded configuration file. In this case, ‘New’ is displayed because the file has not yet been saved. Select Preset – drop-down box permitting selection of one of the 9 presets making up the configuration file. Preset Custom Name ‡ – text box for the name of the preset. This will be displayed in the FlashMic during power-up (if the preset was the last used before power-down). Note that underscore characters are used to insert spaces in the example preset name, PSET_1. SAVE Clicking this button saves the configuration file currently loaded in FlashMic Manager to the same filename it had when it was opened. If the file has been created from new (as in the example case), a standard Save File As window for a new filename will be opened first. The default name offered is Presets.cfg, but the user may substitute any other filename preferred. Clicking the SAVE button is equivalent to selecting File>Save, or using the keyboard shortcut CTRL + S. En.27 Preset Configuration ENGLISH Record Mode ‡ – this drop-down box lets you determine the file type and sample rate from 6 options: RECORD MODE FILE TYPE SAMPLE RATE MAXIMUM RECORDING TIME LIN48K BWF files (uncompressed) 48kHz 3hr LIN44K BWF files (uncompressed) 44.1kHz 3hr 15min LIN32K BWF files (uncompressed) 32kHz 4hr 30min MP48K MPEG1 (Layer 2) files 48kHz 12hr 15min MP44K MPEG1 (Layer 2) files 44.1kHz 14hr 40min LIN32K MPEG1 (Layer 2) files 32kHz 18hr 25min Audio Format – confirms selected audio algorithm Sample Rate – confirms selected sample rate Encoded BitRate – confirms effective bitrate of data being written into memory PreRecord Buffer ‡ – drop-down box for setting the duration of the FlashMic’s pre-record buffer in 1 second increments from zero (off) to 10 seconds. (Set to OFF in example) See section on PreRecord Buffer, page 36 for more information. Record Volume/AGC ‡ – If the AGC box is checked (as in this case), the Record Volume drop down box will be greyed-out. With this setting, the AGC circuit is turned on, and no fixed record level is set. If the AGC box is unchecked, the Record Volume drop-down box permits setting of the record level in 5dB increments from 5dB to 40dB. See Adjusting Record Level, page 13 for more information. High Pass Filter ‡ – FlashMic includes a 100Hz 12dB/octave high-pass filter which can be switched in and out. Backlight ‡ – the display panel backlight in FlashMic can be set to be permanently on or off, or to “Energy-Save mode”, where the backlight illuminates for a short period when a button is pressed. The battery life will be noticeably shortened if the backlight is set to “Always On”. En.28 BWF/MPEG File Info See File Name Structure, page 35 for more information. Note: The data in the next three fields is written into the BEXT data chunk of the .wav file, and can be read by any compatible editing system. Company Name – This field is optional and can be used for reference and housekeeping purposes. Max. length is 31 characters. Reporter Name - This field is optional and can be used for reference and housekeeping purposes. Max. length is 31 characters. Description - This field is optional and can be used for reference and housekeeping purposes. Max. length is 255 characters. Other Features and Functions DRM Configuration Enable Configuration Changes in DRM – Setting this to “No” restricts the range of menu options available in the FlashMic itself. Refer to the table within Using the Menus, page 16 to see which parameters will not be alterable by the user. Setting this option to “Yes” enables the full range of menu options. Battery – this drop-down box is for setting the type of batteries being used. It changes the characteristic of the battery status display on the FlashMic to reflect the different discharge rates of the two types. USB Connection Send this configuration file to DRM Clicking this button initiates the upload of the configuration file currently loaded in FlashMic Manager into the FlashMic. Download Audio Data from DRM Clicking this button initiates the download of the sound files currently in the FlashMic to the computer (see section Transfer Using FlashMic Manager, page 13 for more details). En.29 ENGLISH File Name ‡ - The text in this field (default text ‘TRACK’ in the example) will form part of the header of all sound files recorded in the FlashMic with this preset. This is to assist later identification. Note the file name can be different for each preset in the configuration file. The name can have up to 31 characters. Connection Status The large “LED” indicator at the top right of the window indicates whether a FlashMic is connected to the computer. It is red when a FlashMic is not connected, and turns green when a successful connection is established. Menu Bar Many of the options available in the menu bar are standard to all Windows™ applications and need little explanation: File> New: clears all parameter fields, allows creation of new configuration file. shortcut: CTRL + N) (Keyboard Open: opens “Select file to Open/Load” dialogue box to permit selection of existing configuration file to load. (Keyboard shortcut: CTRL + O) ENGLISH Save: Saves currently-loaded configuration file as existing filename, unless it is a new file being saved for the first time, in which case the “Save File As” dialogue box opens, for file naming. (Keyboard shortcut: CTRL + S) Save As: opens “Save File As” dialogue box to permit file naming before saving. (Keyboard shortcut: none) File Repair: opens a routine to allow a FlashMic audio file that has become corrupted (due to power failure etc.) to be recovered. This routine scans the FlashMic’s memory and checks for correct file lengths and EOF markers, and applies fixes where necessary and possible. A report is provided identifying fixed and lost files. (This functions in the PC version only.) Exit: closes FlashMic Manager. (Keyboard shortcut: CTRL + E) Settings> Set Date and Time: opens “Set Date and Time” dialogue box, permitting the FlashMic’s internal clock to be reset. This clock is used to time-stamp recorded audio files. (Keyboard shortcut: CTRL + T) Note this menu option is unavailable unless a FlashMic is connected to the computer and turned on. Set Date and Time Window Set DRM Name: opens “Set DRM Name” dialogue box, allowing the name of the FlashMic currently connected to be changed (maximum 6 characters). The factory default name is DRM85. This name forms part of the file header of each recorded sound file, so renaming the FlashMic to a unique name (e.g., that of the user) is of great assistance when multiple FlashMics are employed. (Keyboard shortcut: CTRL + R.) See FlashMic File Names, page 35 for more information. Note this menu option is unavailable unless a FlashMic is connected to the computer and turned on. Set DRM Name Window En.30 Presets> Set Default Values: resets all parameter fields of the FlashMic Manager window to the factory default values determined by the file Defaults.cfg, for the currently selected preset (1 – 9). Any existing set of preset values is overwritten, but the configuration file to which they belong is unchanged. The configuration within the FlashMic also remains unchanged until a file upload is performed. This menu option is unavailable unless a configuration file has already been loaded into FlashMic Manager. (Keyboard shortcut: CTRL + D) Clear Preset Values: simply clears all parameter windows; the loaded configuration file and the FlashMic itself are unchanged. (Keyboard shortcut: CTRL + L) Help> Help: opens the Help file. (Keyboard shortcut: F1) About: displays the FlashMic Manager software version number. ENGLISH Status Bar A set of useful additional information is displayed in FlashMic Manager’s status bar: This consists of (left to right across the status bar): FlashMic connection status Name of currently-connected FlashMic Version No. currently-connected FlashMic’s firmware Current Date and Time (as derived from the computer) Status Bar En.31 Connecting the FlashMic When connecting the FlashMic to the computer running FlashMic Manager, always ensure the FlashMic is powered and in IDLE mode first. Connect to the computer with the USB cable supplied. If the FlashMic is in Record mode the USB connection will be ignored, and will time out. In this case, the connector will need to be removed and reconnected after recording has finished for the USB connection to be made successfully. When the FlashMic is “recognised”, the FlashMic Manager window will display the parameter values of the currently-selected preset in the FlashMic itself*. The Current Config file: filename will show “File in DRM is ‘xxx.cfg’”, where ‘xxx’ is the name of the configuration currently loaded into the FlashMic, and the Select Preset box will be set to zero. The status bar will confirm that FlashMic Manager is now displaying the FlashMic’s internal settings with the message “Current active preset settings on DRM”. *On connecting the FlashMic, a standard USB connection window (titled ‘DRM’ in this case) may open offering various options; click Cancel to dismiss this window. ENGLISH Note that connecting the FlashMic to the computer will always attempt to ‘force’ FlashMic Manager to display the FlashMic’s internal settings, and that this operation will overwrite any other data. If unsaved preset data is already displayed, a prompt message to Save the current data will be displayed on connecting the FlashMic. Hint: Saving the settings held in the FlashMic to a new configuration file allows you to copy one FlashMic’s settings to other FlashMic’s, or to a different computer. En.32 Creating a New Configuration File • Click File>New (or enter CTL + N). This clears all the data entry fields and enters ‘New’ as the Current Configuration file name. • Enter data for the first preset (Preset 1) in all data entry boxes in the Current Config file, Preset Configuration and DRM Configuration areas of the window. Note that all these fields are mandatory. The File Name in the BWF/MPEG File Info area is also mandatory, but Company Name, Reporter Name and Description are optional and may be left empty if wished. Note that only the characters A-Z and 0-9 are allowed in the File Name field. • Click the SAVE button (or click File>Save, or enter CTL + S). The Save File As dialogue box opens. Enter a name for the configuration file in the File name box and click Save. The dialogue box dismisses. In the FlashMic Manager window, note the Current Configuration file name is now the name just entered. • If you want to create further presets within this configuration file, select a new number in the Select Preset drop-down box (it is normal, though not essential, to work in numerical order!), which clears all the data entry boxes. Enter the data for the new presets in turn, as before. Note that two options in the DRM Configuration area of the window - Battery and Enable Configuration changes in DRM – retain the selection that was made when creating the initial preset. This is because these two parameters are ‘global’, and apply to all the presets in the configuration file. • On SAVEing, the configuration file already created will be updated with the additional presets. It is then possible to upload this configuration file. See Uploading a Configuration File to the FlashMic. Modifying an Existing Configuration File You may wish to change an existing configuration file in some way, or possibly use an existing file as a starting point for a different one. Any parameters in one or more presets may be changed. • Click File>Open (or enter CTL + O). The Select file to Open/Load dialogue box opens. • The available configuration files (*.cfg) will be listed. Select the file to be used, and click Open. This dismisses the dialogue box, and FlashMic Manager will now be loaded with the file. The filename appears as the Current Configuration file in the window’s top area. • The data for Preset 1 is displayed. Either modify the parameters for this preset, or select a different preset for modification. • After all necessary changes have been made to the chosen preset, click SAVE if you don’t want to keep the original set of preset parameters (i.e. in the configuration file you opened). The set of presets will be saved as a configuration file with the same name. If you want to create a new configuration file from the altered presets, click File>Save As, and enter a new name in the Save File As dialogue box which opens. Click Save. • If you attempt to open a different preset before saving the changes to the current one a warning will open, prompting you to save the changes first. Creating a Personalised Defaults File You may wish to modify the Defaults.cfg file to include parameter values specific to your operation. In this way, when Presets>Set Default Values is selected, your own personalised settings are loaded into the FlashMic Manager data fields. Refer to Modifying an Existing Configuration File and open Defaults.cfg. Modify the data as desired in Preset 1, then Save to the existing Defaults.cfg file name. ! When modifying Defaults.cfg do not change the Preset Custom Name from PSET_1. En.33 ENGLISH To create a different preset (or presets), you must first create a new configuration file. Uploading a Configuration File to the FlashMic After modifying or creating a configuration file, you will want to load it into the FlashMic. This can be carried out immediately after editing the configuration file. ENGLISH • Launch FlashMic Manager, if not already open. • Switch the FlashMic on. • When the FlashMic is in IDLE mode, connect it to the computer with the USB cable supplied. • The LCD display will show USB, and the large red indicator in the FlashMic Manager window will turn green. There should also be some audible and/or visual confirmation on the computer that the FlashMic has been ‘recognised’. (Exactly what form this confirmation takes may vary slightly from computer to computer. Ignore any window called DRM85 that may open.) FlashMic Manager will display the parameter values of the FlashMic’s currently selected preset. • On FlashMic Manager, click File>Open (or enter CTL + O), and select the configuration file that you wish to load into the FlashMic. • Click the button Send this configuration file to DRM. A message window will open after a short delay, confirming that the configuration file has been transferred. • Unmount the FlashMic and unplug the USB connector. The FlashMic reverts to IDLE mode. Any of the new presets making up the configuration file just loaded may now be used by recalling it using the Preset Menu. See Preset Menu, page 17 for more details. ! Do not edit the .cfg files in any text editor on a PC or MAC as the text capitalisation or the syntax may be corrupted, and the preset files will not work correctly. PreRecord Buffer The FlashMic incorporates a pre-record buffer of up to 10 seconds (adjustable). When enabled, audio collected by the microphone is constantly being written into a buffer memory – separate from the main memory – at all times as long as the FlashMic is powered. Thus the last few seconds of audio are always already stored inside the FlashMic. When the REC button is pressed, the contents of the buffer is written into the main memory, while the ‘live’ audio continues to be written into the buffer. When the M/STOP button is pressed, the contents of the buffer continues to be written to the sound file, so nothing is lost. When the recording is replayed, it will be found that it begins with a few seconds of audio immediately before the REC button was pressed. There are no controls on the FlashMic itself for the pre-record buffer; it is enabled and has its duration set from the FlashMic Manager software, as part of a preset configuration. The pre-record buffer can be set from 0 to 10 seconds, in one second increments. Setting Pre-record Buffer Time It should be clear that if all sound files are created with 10 seconds of pre-record buffer enabled, available memory will be used up more rapidly. A degree of experiment may be necessary to find an optimum setting for the length of the pre-record buffer. It is recommended that the buffer is deselected (by setting the duration to ‘OFF’ in FlashMic Manager) for recording situations where it is unlikely to bring any benefit. En.34 FlashMic File Names Frequently, the number of sound files to be downloaded from a FlashMic may be quite large. Furthermore, the FlashMic may have been used in several different locations, and/or by different journalists/recordists. Thus it is important to identify sound files at the time of recording so that their identity and origin can be correctly attributed. A written (or electronic) recording log is recommended elsewhere in this manual, and it is good professional practice to maintain such a log. FlashMic Manager additionally provides the user with the scope for considerable extra assistance in file identification in the form of definable file header information. Filename Structure MIC NAME_BWF FILE NAME_TRACK NUMBER.wav The three components of the filename are specified in FlashMic Manager as part of a preset definition. After the configuration file containing the preset parameters is uploaded to the FlashMic, some of the textual data that was entered in FlashMic Manager is used to form part of the filename. The three components of the filename are derived as follows: • MIC NAME – this is the name set in FlashMic Manager at Settings>Set DRM Name. This name applies to all presets defined for a particular configuration file. In an organisation using mulitple FlashMics, it allows each to be given an individual name, which might be MIC_nn, for example, or possibly a recordist’s name (if recordists always use the same FlashMic). The maximum length of the Mic Name is 6 characters (upper case alphanumeric only). • BWF FILE NAME – this is the name entered in the File Name field (in the BWF/ MPEG File Info area) of FlashMic Manager. This field can be set differently for each preset in a configuration file. This field can be utilised in a variety of ways depending how the FlashMic is to be used; one possibility might be to create presets which differ only in the file name, relating textually to different interviews that the FlashMic is to be used for on a particular day. The maximum length of the File Name is 31 characters (alphanumeric only and spaces not allowed – use underscore). • TRACK NUMBER – this part of the filename is generated within the FlashMic itself, and is simply the number of the recording, which automatically increments by one every time a new recording is made. It is displayed as TRKnnn in the FlashMic LCD. The format of the track number is also TRKnnn, where nnn is the track number. Note that the track number does not reset to zero when a different preset is selected in the FlashMic, when a new configuration file is uploaded, nor when the sound files are downloaded. Reformatting the memory (see section Reformatting the Memory for more information) does reset the track number counter. Some examples of sound file filenames are shown below. Filename structure within FlashMic En.35 ENGLISH The sound files recorded in FlashMic are .wav files, with filenames made up of three concatenated components separated by underscore characters as follows: In the example, several files are in the FlashMic’s AUDIO folder. The first of these is named MIC_01_JOHN_TRK001.wav. In this filename, MIC_01 is the FlashMic name that was set in FlashMic Manager for the configuration file loaded into the FlashMic. JOHN – possibly the recordist’s name - is the BWF/MPEG File Name set in FlashMic Manager for one of the presets. We do not know from the .wav filename which preset number this was, but ‘John’ would have had this information, and would have selected this preset. TRK001 is the track number – the first recording of the day, perhaps. ENGLISH Looking at the other filenames in the folder, it can be seen that they all begin with MIC_01, which would be the case if the FlashMic name (DRM Name) was not changed during the course of the recording period, by uploading a new configuration file with a different DRM Name. Some of the files differ in the BWF/MPEG File Name component; this is where the FlashMic was used by – in our example – different recordists, who each selected a different preset. Note finally, that no track number is repeated. Further recording identification can of course be obtained from the date/time file information, which will be accurate as long as the internal clock was set correctly beforehand. How you will use the file naming system will greatly depend on the type of organisation using the FlashMic(s), how many are in use, how many people are using each FlashMic, the kind of recordings being made, etc. In the simplest of single-mic/single-owner situations, all the default settings can be used with little chance for confusion. Reformatting the Memory The FlashMic’s 1GB flash memory can be reformatted if wished. This is desirable after a firmware update, and is essential if the FlashMic is formatted via USB from a computer. It is also a convenient method of clearing all sound files from the memory. ! IMPORTANT: Reformatting the flash memory will permanently delete any sound files and Preset data still in the FlashMic, so ensure that all your sound files have been downloaded to a computer before proceeding. To reformat the internal memory, proceed as follows: • With the FlashMic turned off, hold down all three side panel buttons - REC (G), PLAY (H) & M/STOP (M) – simultaneously. • With the three buttons depressed, turn the FlashMic on. The LCD display will show FMT N. If you are sure you want to proceed, using the jogwheel make a SHORT DOWN TURN to change the display to FMT Y, then a SHORT PUSH to accept this. • The display will now show FORMAT. Reformatting takes about 35 seconds to complete. The FlashMic then returns to IDLE mode. FORMAT FlashMic LCD Display During Format. En.36 Firmware Updates As a responsible manufacturer, HHB adopts a policy of continuous product development. As with all software-based products, it may be desirable from time to time to update the firmware in your FlashMic with a more recent version. You can contact your HHB dealer or distributor, or visit the FlashMic website at http://www.flashmic.info for details of firmware updates. Firmware updates are downloadable from the FlashMic website, or if you prefer, from your local dealer/distributor on a CD-ROM. Alternatively, if you are uncertain about performing a firmware update yourself, take your FlashMic to your HHB dealer, who will be happy to do it for you. It is recommended that the internal memory is reformatted after a firmware update. See Reformatting the Memory for further details. For certain updates the new firmware may force a reformat, so it is most important to ensure you have all audio and preset data saved before commencing the firmware upgrade. • First locate the firmware folder and file. Whether you have downloaded the firmware from the FlashMic website or have it on a CD-ROM, it will always be in a folder called FW VER xx-xx-xx, where xx-xx-xx is the firmware version number. This folder will contain a file called DRM85.bin, which is the firmware file itself. Note that the firmware filename does not identify which version it is, therefore it is important to keep it in the folder it ‘arrived in’ for identification. • Ensure that the batteries in your FlashMic are adequately charged, and change them if there is any doubt. NEVER start a firmware update with low batteries, as the FlashMic may be rendered unusable if the batteries run out midway during the update procedure. • Turn the FlashMic on, and connect it to the computer with the USB cable. The LCD display will change to USB, and the computer will signify its recognition of the FlashMic in the usual way. • The FlashMic will be identified in the directory tree as an additional drive (the drive letter will vary from machine to machine). • Drag-and-drop the DRM85.bin file to the FlashMic root (not into any of the three folders AUDIO, CONFIG or FIRMWARE it contains). • When the file transfer is complete, unplug the FlashMic’s USB cable and switch the FlashMic off. • Switch the FlashMic back on again; the LCD display will now show the message UPDATE. The bargraph meter indication will start to move from left to right. • The update will continue and complete automatically. When the bargraph indication is full, the FlashMic will either return to IDLE mode, or enter the Reformat routine (see below). • The new firmware is now installed. Depending on the precise nature of firmware changes in the new version, the FlashMic may now automatically enter the Reformat routine. In this case, the display will now read FMT N. It is suggested that the FlashMic memory is now reformatted. See Reformatting the Memory for further details. It is recommended that a memory format is always performed following a firmware update in any case, so if Reformat is not forced by the upgrade procedure, please perform a Reformat manually.
