Introduction

Congratulations on your purchase of the MTCR Digital Recorder. On occasion, there is a need to record audio in circumstances where a traditional full sized recorder is impractical. Whether it be an extreme sport, a public speaking event, a wedding or a next-to-impossible location sound recording, the MTCR is designed for the difficult audio capture. When talent is at an extreme distance or using a wireless microphone is not practical (knights in armor come to mind), the MTCR can travel with your subject and record professional quality audio, synchronized with timecode. The recorder is unobtrusive and easily hidden in garments and costumes and easy to conceal when used as a “plant” microphone to capture environmental or location sound.

Broadcast Wave Format

With a timecode jam at the start of the production, the audio data file contents include a timing reference to make it easy to synchronize them in the timeline. The industry standard BWF/.WAV file format is compatible with essentially any audio or video editing software.

Versatility

The MTCR can be tethered to a camera to capture a higher quality or backup audio recording. The input connector is the industry standard TA5M jack that accepts any mic or line level signal, and provides bias voltage to power a wide variety of electret lavaliere microphones. The input connection and wiring is compatible with microphones pre-wired for “compatible” and “servo bias” configurations to feed 5-pin inputs on Lectrosonics wireless microphone transmitters.

Setup and adjustment is made through an intuitive interface provided by the keypad and LCD. In keeping with typical Lectrosonics mechanical designs, the housing is machined from a solid aluminum billet for the ruggedness needed in field production.

Battery Installation

The audio recorder is powered by a single AAA Lithium battery for 6 hours of operation.

Zinc-carbon batteries marked "heavy-duty" or "long-lasting" are not adequate.

NOTE: Although alkaline batteries will work in the MTCR, we strongly recommend that they be used only for short-term testing. For any actual production use, we recommend the use of disposable lithium AAA batteries.

Push inward on the release tabs to open the door.

Battery polarity markings Press tabs to open door

Insert the battery according to the markings inside the battery compartment door. The (+) pos. end of the battery is oriented as shown here.

CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.

Compatibility with microSDHC memory cards

Please note that the MTCR and SPDR are designed for use with the microSDHC memory cards. There are several types of SD card standards (as of this writing) based on capacity (storage in GB).

SDSC: standard capacity, up to and including 2 GB – DO NOT USE!

SDHC: high capacity, more than 2 GB and up to and including 32 GB – USE THIS TYPE.

SDXC: extended capacity, more than 32 GB and up to and including 2 TB - DO NOT USE!

SDUC: extended capacity, more than 2TB and up to and including 128 TB – DO NOT USE!

The larger XC and UC cards use a different formatting method and bus structure and are NOT compatible with the MTCR recorder. These are typically used with later generation video systems and cameras for image applications (video and high resolution, high speed photography).

ONLY microSDHC memory cards should be used. They are available in capacities from 4GB to 32GB. Look for the Speed Class 10 cards (as indicated by a C wrapped around the number 10), or the UHS Speed Class I cards (as indicated by the numeral 1 inside a U symbol). Also note the microSDHC Logo.

If you are switching to a new brand or source of card, we always suggest testing first before using the card on a critical application.

The following markings will appear on compatible memory cards. One or all of the markings will appear on the card housing and the packaging.

Pull up on this side of cap to open

Insert the card with the label facing the keypad side of the recorder.

Formatting the SD Card

New microSDHC memory cards come pre-formatted with a FAT32 file system which is optimized for good performance. The MTCR relies on this performance and will never disturb the underlying low level formatting of the SD card. When the MTCR “formats” a card, it performs a function similar to the Windows “Quick Format” which deletes all files and prepares the card for recording. The card can be read by any standard computer but if any write, edit or deletions are made to the card by the computer, the card must be re-formatted with the MTCR to prepare it again for recording. The MTCR never low level formats a card and we strongly advise against doing so with the computer.

To format the card with the MTCR, select Format Card in the menu and press MENU/SEL on the keypad.

NOTE: An error message will appear if samples are lost due to a poor performing "slow" card.

WARNING: Do not perform a low level format (complete format) with a computer. Doing so may render the memory card unusable with the MTCR recorder.

With a windows based computer, be sure to check the quick format box before formatting the card.

With a Mac, choose MS-DOS (FAT).

IMPORTANT

The formatting of the MTCR SD card sets up contiguous sectors for maximum efficiency in the recording process. The file format utilizes the BEXT (Broadcast Extension) wave format which has sufficient data space in the header for the file information and the time code imprint.

The SD card, as formatted by the MTCR, can be corrupted by any attempt to directly edit, change, format or view the files on a computer.

The simplest way to prevent data corruption is to copy the .wav files from the card to a computer or other Windows or OS formatted media FIRST. Repeat - COPY THE FILES FIRST!

Do not rename files directly on the SD card.

Do not attempt to edit the files directly on the SD card.

Do not save ANYTHING to the SD card with a computer (such as the take log, note files etc) - it is formatted for MTCR use only.

Do not open the files on the SD card with any third party program such as Wave Agent or Audacity and permit a save. In Wave Agent, do not IMPORT - you can OPEN and play it but do not save or Import - Wave Agent will corrupt the file.

In short - there should be NO manipulation of the data on the card or addition of data to the card with anything other than a MTCR. Copy the files to a computer, thumb drive, hard drive, etc. that has been formatted as a regular OS device FIRST - then you can edit freely.

iXML HEADER SUPPORT

Recordings contain industry standard iXML chunks in the file headers, with the most commonly used fields filled in.

Features and Controls

Timecode sync port MicroSDHC memory card slot cover Headphone Jack Audio Input

The audio input circuitry is the essentially the same as on Lectrosonics SM and L Series transmitters. Any microphone wired as Lectrosonics "compatible" or "servo bias" will work with the MTCR. See page 10 for details.

If the unit is powered on with a card which hasn't been formatted for the MTCR, a prompt to format the card will appear. Follow the on-screen instructions to format the card. If the card has an interrupted recording on it, the Recovery screen will appear.

If there is no card in the MTCR or the card is not properly formatted, the Main Window appears. Settings are accessed by pressing MENU/SEL on the keypad, and then using the UP and DOWN arrow buttons and BACK button to navigate the menu items and select functions. The buttons also provide alternate functions as labeled by the icons on the LCD.

Operating Instructions

Powering On

Press and hold the Power Button until the Lectrosonics logo appears on the LCD.

Powering Off

Power can be turned off by holding the Power Button in and waiting for the countdown. The Power Button will not work while the unit is recording (stop recording first before powering down) or if the front panel has been locked out by the operator (unlock the front panel first).

If the power button is released before the countdown reaches 3, the unit will remain turned on and the LCD will return to the same screen or menu that was displayed previously.

Main Window

The Main Window provides a view of the battery status, timecode and the input audio level. Icons in the four corners of the screen provide access to the Menu, Info (available recording time if SD card installed, MTCR info if no card in unit), and the REC (record start) and LAST (play last clip) functions. These functions are invoked by pressing the adjacent keypad button as shown on the previous page.

About the "Slow Card" Warning:

If any samples are lost during recording, a warning screen will appear displaying "slow card." Typically the lost audio is less than 10 milliseconds and is barely noticeable. The unit will still be recording while this screen appears. Press the BACK button (OK) to return to the recording screen.

When this happens, there will be no “gap” or brief silence in the recording. Instead, the audio and timecode will simply jump forward. If this happens repeatedly during the recording, it is best to replace the card.

Playback Window

Icons in the Playback Window provide button functions used for playback on a recording device. The icons will change depending on the status of the playback: active playback, paused in the middle, or paused at the end.

Timecode...

TC Jam (jam timecode)

When TC Jam is selected, JAM NOW will flash on the LCD and the unit is ready to be synced with the time-code source. Connect the timecode source and the sync will take place automatically. When the sync is successful, a message will be displayed to confirm the operation.

NOTE: The headphone output will be muted when entering the TC Jam page. Audio will be restored when the cable is removed.

Timecode defaults to zero at power up if no timecode source is used to jam the unit. A timing reference is logged into the BWF metadata.

Frame Rate

The frame rate affects embedding of the timing reference in the BWF file metadata and display of timecode. The following options are available:

NOTE: While it is possible to change the frame rate, the most common use will be to check the frame rate which was received during the most recent timecode jam. In rare situations, it might be useful to alter the frame rate here, but be aware that audio tracks many not line up correctly with mismatched frame rates.

Use Clock

Choose to use the clock provided in the MTCR as opposed to a timecode source. Set the clock in the Settings Menu, Date & Time on page 9.

NOTE: The MTCR time clock and calendar (RTCC) cannot be relied on as an accurate time code source. Use Clock should only be used in projects where there is no need for the time to agree with an external time code source.

Mic Level

Mic Level Gain In dB Audio level 40 120 +0' 3 5

C or L appears here

Use the UP and DOWN arrow buttons to adjust the input gain. When the audio level meter reading exceeds the zero at the top, either a "C" or an "L" icon will appear, indicating respectively clipping in the non-safety track (Split Gain mode) or limiting (HD Mono mode). In HD

Mono mode, the limiter compresses 30 dB of input level into the top 5 dB, reserved for "overhead" in this mode. In Split Gain mode, the limiter would rarely be engaged, but it will engage if necessary (with no graphical indication) to prevent clipping of the safety track.

NOTE: See Record Mode.

HP Volume

Use UP and DOWN arrows to adjust headphone volume.

Scene & Take

Each time recording is started, the MTCR automatically begins a new take. Takes can run up to 999. The scene numbers can be manually entered and are limited to 99.

SD Card...

Format Card

This item erases all files on the card and prepares the card for recording.

Files/Play

Choose to play the files based on their name. Use the arrows to scroll, MENU/SEL to select the file and the DOWN arrow to play.

Takes/Play

Choose to play the files based on scene and take. Scene and take numbers can be manually entered, and are embedded in the filenames and iXML headers of recordings. Take number automatically increments each time the record button is pressed. When browsing by scene and take, recordings that span multiple files are listed singly and played as one long recording.

File Naming

Filenames of the recordings contain industry standard iXML chunks in the file headers, with the most commonly used fields filled in. File naming can be set as:

• Sequence: a progressive sequence of numbers
• Clock Time: the time of the internal clock at the beginning of the recording; recorded as DDHHM-MA.WAV. DD is the day of the month, HH is hours, MM is minutes, A is the overwrite-prevention character, incrementing to 'B', 'C', etc. as needed to avoid a naming conflict A final character serves as the segment identifier, being absent in the first segment, '2' in the second segment, '3' in the third and so on.

- Scene/Take: the progressive scene and take automatically cataloged each time a recording is begun; S01T001.WAV. The initial 'S' is meant to suggest "Scene" but also serves as the overwrite prevention character, decrementing to 'R', 'Q', etc. as needed to avoid a naming conflict. The "01" after the 'S' is the scene number. 'T' means take, and the "001" is the take number. An eighth character is used only for the second and subsequent (4 GB) segments for very large recordings. Scene numbers are entered manually. Take numbers increment automatically.

Settings...

Record Mode

There are two recording modes available in the menu, HD Mono, which records a single audio track and Split Gain, which records two different tracks, one at the normal level and another at -18 dB as a "safety" track that can be used in place of the normal track in the event that overload distortion (clipping) has occurred on the normal track. In either mode, recordings over 4GB are broken into sequential segments so very long recordings (over approx 5 hours in HD mode or 2.5 hours in split mode) will not be a single file.

NOTE: See Mic Level.

NOTE: The headphone output will be muted when recording.

Bit Depth

MTCR defaults to 24-bit format recording, which is a more efficient space saving format. 32-bit is available if your editing software is older and won't accept 24-bit. (32-bit is actually 24-bit padded with zeros, so more space is taken up on the card.)

Date & Time

The MTCR has a real time clock/calendar (RTCC) which is used for timestamping the files it writes to the SD card. The RTCC is able to keep time for a minimum of 90 minutes with no battery installed, and can keep time more or less indefinitely if any battery, even a "dead" battery, is installed. To set the date and time, use the MENU/SEL button to toggle through the options and the UP and DOWN arrow buttons to choose the appropriate number.

WARNING: Since the real time clock/calendar can be manipulated and/or stop with loss of power, it should not be relied upon for accurate time keeping. Only use this option when a time clock is not available.

Lock/Unlock

The LOCKED mode protects the recorder from accidental changes to its settings. When locked, menu navigation is possible, but any attempt to alter settings will prompt a "LOCKED/can use menu to unlock" message. The unit can be unlocked using the Lock/Unlock setup screen. The "dweedle tone" remote control will still work.

Backlight

The recorder backlight can be set to turn off after either 5 minutes or 30 seconds, or to stay on continuously.

Bat Type

Choose either Alkaline or Lithium battery type. The voltage of the installed battery will be shown at the bottom of the display.

NOTE: Although alkaline batteries will work in the MTCR, we strongly recommend that they be used only for short-term testing. For any actual production use, we recommend the use of disposable lithium AAA batteries.

Remote

The recorder can be configured to respond to "dweedle tone" signals from the PDRRemote app or to ignore them. Use the arrow buttons to toggle between "yes" (remote control on) and "no" (remote control off). The default setting is "no."

About MTCR

The MTCR's firmware version and serial number are displayed.

Default

To return the recorder to its factory default settings, use the UP and DOWN arrow buttons to choose Yes.

Firmware Updates

Firmware updates are made using a microSDHC memory card. Download and copy the following firmware update files to a drive on your computer.

- MTCR vX_xx.ldr is the firmware update file, where "X_xx" is the revision number.

In the computer:

1) Perform a Quick Format of the card. On a Windows-based system, this will automatically format the card to the FAT32 format, which is the Windows standard. On a Mac, you may be given several options. If the card is already formatted in Windows (FAT32) - it will be greyed out - then you do not need to do anything. If the card is in another format, choose Windows (FAT32) and then click "Erase." When the quick format on the computer is complete, close the dialogue box and open the file browser.
2) Copy the MTCR v1_xx.ldr file to the memory card, then safely eject the card from the computer.

In the MTCR:

1) Leave the MTCR turned off and insert the microSDHC memory card into the slot.
2) Hold down both the UP and DOWN arrow buttons on the recorder and turn the power on.

continued on next page...

3) The recorder will boot up into the firmware update mode with the following options on the LCD:

• Run - Exits the update mode and starts up the recorder in the normal operating mode.
• Update - Displays a scrollable list of the .Idr files on the card.
• Power Off - Exits the update mode and turns the power off.

NOTE: If the unit powers on normally instead of offering the options in Step 3 (above), power the unit off and try again, making sure that both arrow buttons are firmly depressed while powering the unti back on.

4) Select Update. Use the UP and DOWN arrow buttons to select the desired file and press MENU/SEL to begin the update process. The LCD will display status messages while the firmware is being updated.
NOTE: The Update process takes about 20 seconds.
5) When the update is complete, the LCD will display this message: UPDATE SUCCESSFUL REMOVE CARD. After the card is removed, the LCD will return to the three options shown in step 3 above.
6) Select Power Off and press MENU/SEL to finish the update.
7) If you re-insert the same card and turn the power back on for normal use, the LCD will display a message prompting you to format the card:

Format Card?

(files lost)

• No

• Yes

If you wish to record audio on the card, you must re-format it. Select Yes and press MENU/SEL to format the card. When the process is complete, the LCD will return to the Main Window and be ready for normal operation.

If you choose to keep the card as is, you may remove the card at this time.

The firmware update process is managed by a bootloader program - on very rare occasions, you might need to update the bootloader.

- MTCRboot vX_xx.ldr is the bootloader file

Follow the same process as with a firmware update and select the MTCRboot file. Be forewarned, this can corrupt your unit if interrupted. Don't update the bootloader unless advised to do so by the factory.

Recovery Process

Recordings can be reliably recovered even if the card is accidentally removed or the battery dies while a recording is in progress. If a recording is interrupted, all of the audio is present on the card and can be easily recovered by the MTCR. The MTCR keeps track of the length of the most recent recording so it can supply a good suggestion for the length to recover. If the length is ever unknown or the MTCR's suggestion seems incorrect, it is always possible to override the suggested length. If in doubt, specify the maximum length possible, in which case the entire remainder of the card is recovered. All of the interrupted recording will be present, followed by extra contents which might be random noise or audio from previously deleted recordings.

NOTE: A good battery is required to begin the recovery process. If recovery is attempted with a weak battery, a message appears saying that a fresh battery will be required.

Once a fresh battery has been installed, power on the MTCR and insert the card with the interrupted recording. The MTCR will detect the interrupted recording and display.

Recover?

For safe use

See manual

If "No" is chosen, nothing is done to the card and the MTCR will not use the card. If "Yes" is chosen", a prompt appears asking for the length of the recording to recover, specified as a number of hours and minutes. The default suggestion will be the approximate length of the most recent recording. It is always safe to recover a longer recording than was made. To specify the recovery time, use the MENU/SEL button to navigate and specify the hours and minutes fields. Once set as desired, use MENU/SEL to navigate to the "GO!" soft button and press the DOWN arrow button to begin the recovery process.

Recovery is nearly instantaneous. When completed, the display will show

PDRRemote

By New Endian LLC

Convenient remote control is provided by a phone app available on the AppStore and Google Play. The app uses audio tones ("dweedle tones") played through the phone's speaker that are interpreted by the recorder to make changes to the recorder settings:

• Record Start/Stop
• Mic Gain Level
• Lock/Unlock

The MTCR tones are unique to the MTCR and will not react to "dweedle tones" meant for Lectrosonics transmitters.

The screens appear differently for iOS and Android phones, but perform the same functions.

For Best Results

The following conditions are required:

• The microphone must be within range.
- The recorder must be configured to enable remote control activation. See Remote on the menu.

Please be aware this app is not a Lectrosonics product. It is privately owned and operated by New Endian LLC, www.newendian.com.

5-Pin Input Jack Wiring

The wiring diagrams included in this section represent the basic wiring necessary for the most common types of microphones and other audio inputs. Some microphones may require extra jumpers or a slight variation on the diagrams shown.

It is virtually impossible to keep completely up to date on changes that other manufacturers make to their products, thus you may encounter a microphone that differs from these instructions. If this occurs please call our toll-free number listed under Service and Repair in this manual or visit: www.lectrosonics.com/US

Note: If you use the dust boot, remove the rubber strain relief that is attached to the TA5F cap, or the boot will not fit over the assembly.

Installing the Connector:

1) If necessary, remove the old connector from the microphone cable.
2) Slide the dust boot onto microphone cable with the large end facing the connector.
3) If necessary, slide the 1/8-inch black shrink tubing onto the microphone cable. This tubing is needed for some smaller diameter cables to ensure there is a snug fit in the dust boot.
4) Slide the backshell over the cable as shown above. Slide the insulator over the cable before soldering the wires to the pins on the insert.
5) Solder the wires and resistors to the pins on the insert according to the diagrams shown in Wiring Hookups for Different Sources. A length of .065 OD clear tubing is included if you need to insulate the resistor leads or shield wire.

6) If necessary, remove the rubber strain relief from the TA5F backshell by simply pulling it out.
7) Seat the insulator on the insert. Slide the cable clamp over the and of the insulator and crimp as shown on the next page.
8) Insert the assembled insert/insulator/clamp into the latchlock. Make sure the tab and slot align to allow the insert to fully seat in the latchlock. Thread the backshell onto the latchlock.

Service and Repair

If your recorder malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions and check the interconnecting cables.

We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don't attempt to adjust any controls inside the units. Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are no adjustments inside that will make a malfunctioning unit start working.

LECTROSONICS' Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone for out-of-warranty repairs.

Returning Units for Repair

For timely service, please follow the steps below:

A. DO NOT return equipment to the factory for repair without first contacting us by email or by phone. We need to know the nature of the problem, the model number and the serial number of the equipment. We also need a phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed your repair through our receiving and repair departments. The return authorization number must be clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the proper packing materials. UPS is usually the best way to ship the units. Heavy units should be "double-boxed" for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
