Description

Overview

The ZMT4-Flex miniature wideband transmitter adds a soft and durable silicon rubber case to the ZMT4, allowing the transmitter to bend and flex as necessary. It's designed to keep both your talent and your transmitter safe when recording.professional sports or other potentially high-impact scenarios.

The ZMT4-Flex is extremely lightweight (3 oz, with battery) and compact (4.8" x 1.7" x 0.4"). It has two microdot input connector for use with either a single mono or dual lavalier set-up.

Despite its incredibly low profile, it requires almost no compromises, sharing most of the features of its larger siblings, including built-in backup recording with time code, NeverClip™ for superior dynamic range, full encryption, and Zaxcom High Density (ZHD) modulation.

ZHD modulation allows for up to 10 channels of wireless to be operated in one MHz of frequency spectrum space. The wireless signal is only 50 KHz wide and can be spaced as close as 100 KHz channel to channel allowing up to sixty channels of ZHD wireless in a single 6 MHz American television channel. The new modulation is ultra efficient resulting in incredible transmission range.

The ZHD transmitters are capable of running all existing mono Zaxcom modulations maintaining compatibility with all currently produced Zaxcom receivers. ZHD modulation conforms to all currently proposed FCC regulations for spectrally efficient wireless transmission.

Channel spacing varies based on the receiver you pair it with:

With wireless receivers in Mono or XR Modes: as close as 400 KHz channel to channel
With the QRX235, QRX200 or QRX212 in ZHD mode: as close as 200 KHz channel to channel (300 KHz recommended)
With the QRX335, QRX300 or QRX312 in ZHD mode: as close as 100 KHz channel to channel

The ZMT works with ZaxNet, Zaxcom’s 2.4-GHz RF network that distributes remote control commands, time code and IFB audio. With ZaxNet, you can remotely control transmitter settings such as gain, frequency channel selection, transport controls and output power levels. When paired with an IFB100/200 and Deva or Fusion, the units can also replay audio via a time code reference giving production sound mixers the ability to replay and remix audio, creating a virtual multi-track playback and re-record system.

Consumer Alert

Starting in 2017, the 617-652 MHz and 663-698 MHz frequencies are being transitioned by the Federal Communications Commission (FCC). Users of wireless microphone devices that operate in any portion of those frequencies must cease operating on these frequencies no later than July 13, 2020. In addition, users of this device may be required to cease operations earlier than that date if their operations could cause harmful interference to a 600 MHz service licensee’s wireless operations on these frequencies. For more information, visit the FCC’s wireless microphone website at www.fcc.gov/wireless-microphones-guide or call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC).

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this 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); and it has no protection from interference received from any other device.
