Zaxcom ZFR200/300 User Manual

The Zaxcom ZFR (Zaxcom Flash Recorder) is a compact recorder designed to be the same size as a Zaxcom wireless transmitter. It accepts standard lavaliere microphones, and a stereo ZFR can accommodate two lavaliere microphones. The ZFR provides a convenient method for recording isolated (ISO) tracks for multiple talents without concerns about RF range or interference. It can be configured to jam time code via ZaxNet upon power-up and transmit QC audio with time code within 10 seconds. The ZaxNet transmission allows for close-range audio monitoring and can serve as a time code master to wirelessly synchronize other body pack recorders or wireless transmitters. Body packs can periodically re-jam time code to maintain sub-frame accurate synchronization. After a shoot, SD memory cards are collected from the ZFR for post-production, where ISO tracks can be easily integrated into non-linear editing systems for clean, time-coded audio. Recording systems can be as simple as a single ZFR recorder paired with an ERX2TCD receiver for wireless monitoring of audio and time code. Multiple ZFR recorders can create an extensive virtual multi-track recording system, overcoming the limitations of traditional wireless microphones regarding audio quality, range, and RF interference.

Exiting the Main Menu: Press and hold the MENU key for 1.5 seconds to exit.

Microphone Gain Adjust

This menu allows adjustment of microphone gain in decibels (dB). The display shows the gain setting and a horizontal meter indicating the audio signal level. For stereo units in stereo mode, two meters are displayed, one for each channel, with gain applied to both sources.

High Pass Filter

The high pass filter can be enabled and adjusted within this menu. The filter range is from 70Hz to 220Hz, with adjustments available in 10Hz increments.

Time Code Frame Rate Set

This setting determines the time code frame rate. The ZFR supports and records standard time code frame rates including 23.98, 24, 25, 29.97DF, 29.97DF, 30 DF, and 30 NDF.

Extended Menu

The Extended Menu provides access to advanced settings.

High Pass Filter

This function allows adjustment of the high pass filter, with a range from 70Hz to 220Hz in 10Hz steps.

Record Format Set

This setting configures the recording mode. Options include 'US MONO' for mono recording and 'STEREO' for stereo recording. A reboot of the ZFR is required after changing this setting.

IFB Voting Enable

This feature allows the ZFR's ZaxNet receiver to automatically select and switch to the strongest signal from two different ZaxNet transmitters. This is useful on large sets where a second IFB transmitter can be placed at a different location. To enable IFB voting, the second IFB transmitter's frequency must be set exactly 2MHz higher than the first. This feature is only available when the IFB is set to normal RX mode and not set to off.

IFB Mode

This menu configures the ZaxNet IFB transceiver's operational mode:

• OFF (NORMAL RX): Receive only mode. The ZaxNet transceiver receives ZaxNet signals but does not transmit, disabling ZaxNet TC and audio transmission.
• 0 SECS: TX ONLY: Transmit only mode. The ZaxNet transceiver transmits ZaxNet TC and audio but does not receive wireless TC or ZaxNet commands.
• 20 SECS: Receive then Transmit mode. After power-up, the ZaxNet transceiver searches for a ZaxNet signal for a specified duration to receive and lock time code before transmitting TC and confidence audio. This is necessary for locking to ZaxNet time code before transmitting confidence audio. A power cycle is required after changing this setting.

ZaxNet Receive Frequency Set

This setting configures the ZaxNet receive frequency, which determines the frequency for receiving wireless time code and remote control commands. This frequency must match the corresponding ZaxNet transmitter (e.g., QRX, Nomad, TRX900CL, IFB100/200). The display shows the receive frequency (RXFREQ) and a signal strength meter.

ZaxNet Transmit Frequency Set

This sets the ZaxNet transmit frequency, used for broadcasting time code and audio for confidence monitoring via receivers like the ERX or Nomad. The expected range for this transmitted audio is less than 20 feet.

IFB Receive Pulse Set

This setting determines how often the ZaxNet transceiver stops transmitting to search for time code when sending ZaxNet confidence audio. Options include 'NEVER' (stays in transmit mode) or an interval between 10 and 999 seconds. This allows the ZFR to re-jam its time code wirelessly at set intervals.

IFB Transmit Power Level

Sets the power level of the ZaxNet transmitter, with settings ranging from 0 to 7, where 7 is the highest power.

IFB Record Beep

When enabled, an audible beep is heard on the ZaxNet confidence audio every 20 seconds to confirm recording. This beep is only heard on the receiver and is not recorded.

Power-Up Mode

Configures the state of the unit's keys after power-up:

• LOCKED: Keys are automatically locked to prevent accidental changes.
• UNLOCKED: Keys remain unlocked. They can be locked manually via the lock screen in the Main Menu. To unlock at any time, simultaneously press the MENU and INC keys.

SD Card Format

This menu is accessed if a card was inserted before booting. It allows the Micro SD card to be erased and formatted. Formatting in the ZFR is required for proper operation, even if cards are preformatted. Users can name the ZFR, and this name is included in recorded file names for easier identification. The card naming menu is in the Extended Menu.

To Format an SD Card:

1. With the unit powered off, insert the Micro SD card with the label facing the back. Press until it clicks.
2. Power up the ZFR while holding the MENU key to enter the Extended Menu.
3. Press the INC key until the SD Card Format menu appears.
4. Press the INC key five times.
5. The screen will display "FORMATTING FAT 32".
6. After approximately one minute, "SUCCESS" or "FORMAT FAILED ERROR" will be displayed.
7. If "SUCCESS" appears, power cycle the ZFR.
8. If "FORMAT FAILED ERROR" occurs, try re-formatting. If it fails again, the card is not recommended for use.

TC Jam Mode Select

This menu controls whether the ZFR enters record mode upon receiving a record run time code:

• AUTO-JAM NORMAL: Continuously jams time code via ZaxNet.
• AUTO-LOAD REC RUN: Continuously jams time code via ZaxNet and starts/stops recording when record run time code is received. The ZFR enters record mode with rolling time code and stops when the time code stops. If time code is lost due to a weak IFB signal, recording continues until the signal is restored.

Time Code Source Select

This menu selects the source for receiving time code:

• IFB (RF): Receives time code via ZaxNet from sources like Nomad, QRX, IFB100/200, TRX900CL, or other ZFR recorders.
• AUDIO INPUT: Receives time code via the microphone input using a suitable cable. The ZFR typically recognizes connected time code within three seconds, indicated by "TIME CODE" followed by "JAM" on the screen. Once "JAM" disappears, the source can be disconnected. For microphone input, the time code signal level should be between -30 and -10 dBFS to avoid clipping.

Mute Time Code Transmission Until Jammed

When set to ON, the ZaxNet transmitter will not broadcast time code until its internal time code generator is jammed. This prevents the ZFR from sending incorrect time code.

Group ID Set

Assigns the ZFR to a specific "GROUP" for ZaxNet control. For example, a ZFR set to Group 1 is controlled by a ZaxNet transmitter set to Group 1. This allows for controlled operation of multiple recorders without interference and helps manage multiple users sending commands. Most users set this to 1 for all Zaxcom products. Group codes can range from 1 to 99.

Unit ID Set

Assigns a unique number to identify the ZFR within a group, enabling independent control of individual ZFRs. For instance, to adjust gain for each ZFR separately, assign a different Unit ID to each. Unit IDs can be set to 'ALL' or any number from 1 to 200.

Dynamics

The Dynamics section controls a soft knee compressor and expander located after the analog-to-digital converter. It limits dynamic range to prevent clipping during loud audio events. The compressor can be set to mild or extreme compression with a soft knee for transparent operation.

To enter the dynamics menu: Press the INC or DEC key to display "PARMS" (parameters). Press the MENU key to move to the next parameter. Hold the MENU key for 1 second to exit.

Dynamics Parameters:

• Link L-R: OFF / ON. Links left and right channels for stereo recording to ensure consistent compression/expansion.
• SPEED (Decay Speed): SLOWEST / SLOW / NORMAL / FAST / FASTEST. Sets how gradually the signal level decreases after reaching the threshold. Typically set to FAST.
• ATTACK (Attack Speed): SLOWEST / SLOW / NORMAL / FAST / FASTEST. Sets how quickly gain is reduced once the signal exceeds the threshold. Typically set to FAST.
• CMP RATIO (Compressor Ratio): Range: 1.0:1 to 5.0:1 in 0.1 steps. Determines the amount of gain reduction. A 2.0:1 ratio means for every 1 dB above the threshold, gain is reduced by 2 dB. Higher ratios increase compressor aggressiveness.
• CMP THRESH (Compressor Threshold): Range: 0 to -96dB in 1dB steps. Sets the level at which gain reduction occurs.
• CMP KNEE (Compressor Soft Knee): Range: 0 to 20dB in 1dB steps. Softens the audible transition between uncompressed and compressed audio, especially useful for higher ratios.
• EXP RATIO (Expansion Ratio): Range: 1:1.00 to 1:4.00 in 0.01 steps. Sets the expansion ratio. For example, a 1:2.0 ratio means for every 1 dB below the expansion threshold, gain is reduced by 2 dB.
• EXP THRESH (Expansion Threshold): Range: 0 to -96dB in 1dB steps. Sets the threshold above which gain reduction occurs.
• REDUCE (Expander Gain Reduction): Range: 0 to -36dB in 1dB steps. Limits the amount of gain reduction from the expander.
• GAIN (Make-up Gain): Range: 0 to 30dB in 1dB steps. Compensates for gain reduction caused by the compressor, allowing for an optimum output level.

Battery Type Set

This menu is for TRX units to send battery data to a QRX receiver and is not applicable to the ZFR.

Recording Mode Set

Configures the ZFR's behavior after reaching the card's file capacity (maximum 256 files per card):

• NON-LOOP RECORD (recommended): Recording stops when the card is full, and "FULL" is displayed. This prevents overwriting audio.
• LOOP RECORD: When the card is full, new audio overwrites the oldest audio on the card.

Allow IFB Remote Control

Enables or disables the ZFR's acceptance of remote roll and gain change commands via ZaxNet. If set to OFF, the ZFR will not receive ZaxNet commands. Note that if the ZFR is transmitting ZaxNet, it will not receive remote control commands regardless of this setting.

Low Battery Stop Set

Allows setting a delay after a low battery warning before the recorder stops recording and closes the current file. This helps prevent file corruption. Options:

• NEVER STOP: Recording continues until manually stopped or the battery dies.
• Interval (1 to 99 minutes): After a low battery warning, recording continues for the set time before closing the file and stopping.

Automatic Record After Boot up

Configures the ZFR to automatically start recording upon booting up:

• ON: The ZFR automatically begins recording after booting.
• OFF: The ZFR waits for a ZaxNet command or manual trigger to start recording.

ZFR Name Set

Allows changing the ZFR's name from its default serial number. The entered name is included in recorded audio file names and BWF metadata, aiding in file identification. The maximum name length is 8 characters.

To set/change the ZFR name:

1. Press INC or DEC key to change the character at the current position.
2. Press MENU key to move to the next character.
3. Press and hold MENU key when finished to set the name, or cycle power.

Hide Encryption Menu

This option allows hiding the encryption menu:

• HIDDEN: The encryption menu is not displayed during menu navigation.
• ON: The encryption menu is displayed.

Encryption Code Set

When encryption is enabled, ZaxNet transmitted audio is encrypted and can only be heard by receivers with matching encryption codes. Mismatched codes result in white-noise or silence. Ensure the receiver has the same code. Two sets of numbers form a six-digit code, offering over 16 million combinations. For unencrypted operations, set both codes to 000.

To adjust the encryption code:

1. Momentarily press the MENU key to advance to the next character.
2. Press the INC or DEC key to change the character.
3. Press and hold the MENU key for 1 second to exit.
