VTX1 is the next evolution in IFB transmission combining two types of frequency bands and enhanced features including encrypted audio, timecode, internal recording, and remote capabilities all in one device, making it the most versatile IFB system for any project.

TWO FREQUENCY BANDS ARE BETTER THAN ONE

VTX1 is engineered to transmit both VHF and 2.4 GHz frequency bands for ultimate performance.

The VHF turning range is 192-217 MHz with a 25 kHz RF frequency step. VHF offers two user-selectable operating modes: FM analog and a fully encrypted 100% digital modulation mode. No matter which mode, VTX1 transmits high quality audio to VHF compatible devices including the Zaxcom VRX1.

With its 2.4 GHz frequency band, VTX1 features ZaxNet giving users the ability to send IFB audio, timecode, metadata, and remote control Zaxcom compatible transmitters and receivers.

Through ZaxNet, remote adjustments can be made to the frequency, pre-amp gain, transmitter output power, and put the unit in record, playback, or stop modes - eliminating the need to approach the talent to adjust the device. Better yet, ZaxNet transmits over a single 2.4 GHz RF channel which can be used license-free in almost any country.

COMPATIBILITY

VTX1 is compatible with the Zaxcom VRX1 receiver in VHF FM analog or digital modulation modes.

VHF FM analog audio is also compatible with Comtek receivers and other products operating in the 192-217 MHz frequency range.

KNOWN COMPATIBILITY:

• Comtek BST 75-216
• Comtek BST 25-216
• Comtek M-216

ENCRYPTED AUDIO

The VHF digital modulation mode and 2.4 GHz audio is fully encrypted, keeping transmissions private and secure.

The VHF FM analog mode does not provide encrypted audio.

INTERNAL RECORDING

Audio can be simultaneously transmitted and internally recorded to a memory card that includes timecode. A microSD card slot allows audio to be recorded directly onto the instantly removable card as a backup or reference for post.

Files are recorded using MARF (Mobile Audio Recording Format), a lossless fault-tolerant recording system that eliminates file corruption common to recordings caused by power loss or early card removal.

INPUTS

A TA5 audio input offers a balanced stereo line level or sample rate conversion AES. The BNC connector provides a timecode input while the USB input allows for software updates.

TRANSMISSION POWER

Maximum RF power output is 50 mW in either VHF operating modes and 2.4 GHz.

POWER

VTX1 can be powered externally via Hirose connector and accepts 8 to 18 VDC @ 180 mA.
