TC SOURCE:
ZAXNET (RF)
The time code source menu selects how the transmitter will receive its time code.
ZAXNET (RF) - The ZMT3 will receive time code via ZaxNet from a Nomad, a QRX235, IFB100/200, TRX900CL
or another TRX transmitter or a ZFR recorder that is transmitting ZaxNet time code.
AUDIO INPUT - The ZMT3, with a proper cable, will receive time code via the microphone input.
When time code is connected, it takes the ZMT3 approximately three seconds to recognize the TC. The screen will display TIME CODE followed by JAM when it is recognized. Please note that when using the microphone input connector, the audio level of the time code signal needs to be between -30 and -10 dBFS on the unit’s meter. Any level above -10 may cause clipping, which will prevent proper reading of time code.
TC Jam Mode Select
TC JAM MODE:
AUTO-JAM NORMAL
This menu controls if the ZMT3 will go into record when it receives a record run time code.
AUTO-JAM NORMAL - The ZMT3 will continuously jam time code via ZaxNet and will go into record when receiving a record command via ZaxNet or if the unit is put into record manually by pressing the CARD and
INC keys simultaneously.
AUTO-LOAD REC RUN - In Auto-Load mode the ZMT3 will go into record when it detects rolling time code, and will stop when the time code stops. If time code is lost because the IFB signal is too weak the unit will not stop but will continue in whatever state it was in until the time code signal is restored.

Zaxcom ZMT3 ZaxNet Menu
Group Code Set
REMOTE CONTROL
GROUP CODE = 1
This menu is where the ZMT3 is assigned to a group. The group code allows transmitters to be grouped together so they can be controlled via ZaxNet without affecting others.
So for example a ZMT3 set to Group 1 will be controlled by a ZaxNet transmitter set to Group 1 and a ZMT3 assigned to group 2 will be controlled by a Group 2 ZaxNet transmitter. This is helpful if two or more people on set are sending ZaxNet commands. Therefore the different group codes allow each person to be independent and not interfere with each other. Most users leave the group set to 1 on all of their Zaxcom products. Group codes can be set from 1 to 99.
Unit Code Set
REMOTE CONTROL
UNIT CODE = 001
This menu is where the ZMT3 is assigned a unit code. The unit code is a unique number used to identify each
ZMT3 within a particular group. This allows individual transmitters within the same group to be independently controlled. Each transmitter should have a different unit code.
Unit codes can be assigned any number from 1 to 200.
ZaxNet Voting Enable
This menu will only appear if ZaxNet is set to receive (RX) mode
ZAXNET VOTING:
NORMAL (OFF)
The purpose of voting is to allow the ZaxNet receiver in the ZMT3 to choose, and switch to, the stronger signal from two different ZaxNet transmitters. One purpose of this is if on a large set a second IFB transmitter can be placed at a different location so the ZaxNet receiver in the ZMT3 can choose the stronger signal.
Please note that the second ZaxNet transmitting frequency must be set 2MHz higher than the first ZaxNet transmitter.

IFB RX PULSE
600 SECS
The ZaxNet transceiver will stay in transmit mode and never go into receive mode.
In this example the ZaxNet transceiver will go out of transmit mode every 10 minutes. This setting would be used so the ZMT3 could update its time code while monitoring audio via an ERX receiver.
This menu sets the interval that the ZaxNet transceiver will stop sending confidence audio and search for time code.
When enabled the pulse setting tells the ZaxNet transceiver to leave ZaxNet transmit mode once every XXX seconds and go into receive mode so it can re-jam its time code wirelessly via ZaxNet. This setting would be used so the ZMT3 could update its time code while monitoring audio via an ERX receiver. Please note when the
ZaxNet transceiver searches for ZaxNet it will temporally go out of transmit mode for approximately 1 second as it searches for ZaxNet time code. The settings are NEVER or any interval between 5 and 999 seconds.
Record Beep Set
This menu will only appear if ZaxNet is set to transmit (TX) mode
ZNET RECORD BEEP
OFF
When the record beep is set to ON, and the ZMT3 is recording, the confidence audio sent to the ERX via ZaxNet will have an audible beep, in variable intervals, giving conformation that the ZMT3 is indeed recording. The beeps will only be heard in the ERX and will not be recorded on the card, or be sent to the UHF receiver. The intervals can be set between 2 to 18 seconds in 2 second increments.

Dynamics
DYNAMICS
The dynamics is a soft knee compressor that is located after the analog to digital converter which will limit the dynamic range to prevent clipping during occurrences of loud audio. Dynamics is comprised of both a compressor and an expander, which operate jointly
.
The compressor in the dynamics can set to mild or extreme compression and features a soft knee for more transparent operation.
To enter the Dynamics Menu
Press the INC or DEC key - “PARMS” (parameters) will be displayed on the right.
To move to the next parameter, press the MENU key.
To exit this page, hold the MENU key for 1 second.
Dynamics Parameters
Link L-R: OFF / ON: If using a stereo transmitter this links the left and right signal so if one side of the signal
needs compressing / expansion the other side will do the same to match.
SPEED (Decay Speed) : SLOWEST / SLOW / NORMAL / FAST / FASTEST
Sets how gradual the signal level decreases after a signal reaches the threshold setting. This is typically set to FAST.
ATTACK (Attack Speed) : SLOWEST / SLOW / NORMAL / FAST / FASTEST
Sets the speed in how fast the gain is reduced once the signal exceeds the threshold setting. This is typically set to FAST.
CMP RATIO (Compressor Ratio): Valid range: 1.0: to 5.0:1, in 0.1 steps.
The amount of gain reduction is determined by the compressor ratio setting.
A compressor ratio for example of 2.0:1 means for every 1 dB above the compressor threshold the gain will
be reduced 2dB. A higher ratio setting makes the compressor more aggressive.
CMP THRESH (Compressor Threshold): Valid range: 0 to –96dB, in 1dB steps.
This sets the level in which gain reduction occurs.
CMP KNEE: (Compressor Soft Knee): Valid range: 0 to 20dB, In 1dB steps.
Sets the compressor's soft knee. A soft knee reduces “softens” the audible change from uncompressed to compressed, this is useful especially for higher ratios where the changeover is more noticeable
EXP RATIO (Expansion Ratio): Valid range: 1:1.00 to 1:4.00, In 0.01 steps
Sets the expansion ratio. For example a 1:2.0 expansion ratio means for every 1 dB below the expansion threshold the gain will be reduced 2dB.
EXP THRESH (Expansion Threshold): Valid range: 0 to –96dB, in 1dB steps.
Sets the threshold above which gain reduction occurs.
REDUCE (Expander Gain Reduction): Valid range: 0 to –36dB, in 1dB steps.
This sets the limit on the amount of gain reduction caused by the expander.
GAIN (Make-up Gain): Valid range: 0 to 30dB, In 1dB steps.
Gain is used to compensate for the gain reduction caused by the compressor. Because the compressor is reducing the gain (or level) of the signal, the ability to add a fixed amount of make-up gain at the output is provided so that an optimum level can be reached.

Media
While any size card will work in the ZMT3 transmitter we recommend using a 4GB Micro SD card. We also recommend only buying a brand name card such as Transcend, SanDisk. And very importantly please buy all cards from a reputable dealer because counterfeit cards exist and can cause recording issues.
We also highly recommend that the all cards are tested before taking them out into the field.
Here is a simple testing procedure to determine if the card will function correctly:
1. Format the card in the transmitter.
2. Power cycle the transmitter.
3. Record at least 20 minutes of audio to the card with no time code source.
4. Look at the Main Screen it should still be recording in segment #1.
5. Playback and listen to the file.
Media Capacity
The ZMT3 can use Micro SD cards, up to 16 GB. While any size card will work we recommend using 4GB cards. All cards that are used in the ZMT3 must be formatted in a 3 series transmitter to work properly; cards formatted in any other series transmitter will not record properly. Please note that regardless of the size of the card the onboard recorder will only be able to record up to 500 individual segments on any given card.
Available recording times depend on the selected modulation and are as follows:

NOTICE:
Most users do not need a license to operate a wireless microphone system. Nevertheless, operating a microphone system without a license is subject to certain restrictions:
the system may not cause harmful interference,
it must operate at a low power level (not in excess of 50 milliwatts), it has no protection from interference received from any other device.
Purchasers should also be aware that the FCC is currently evaluating the use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones To operate wireless microphone systems transmitting with greater than 50mW of radiated power, you must qualify as a Part 74 user and be licensed.
This alert does NOT apply to Part 74 users
RF Exposure:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment is in direct contact with the body of the user under normal operating conditions.
