Zaxcom ZMT4-X Bodypack Transmitter
Built for long days, the Zaxcom ZMT4-X is a bodypack transmitter that runs up to 16 hours on a single Motorola battery.
Its two microdot inputs take one lavalier in mono mode or two in stereo mode. The Motorola BT100 or BT110 (PMNN4468A) battery also gives 48 hours of standby on a charge.
Encrypted Audio and Recording
Audio goes out fully encrypted and records at the same time to a microSD card inside the transmitter, with timecode. Recordings use Zaxcom’s MARF format, which keeps the file intact if the battery dies or the card comes out early.
ZaxNet Remote Control
ZaxNet is Zaxcom’s 2.4 GHz control link. From a ZRC remote or any ZaxNet device, the operator can change the frequency, output power, and input gain, start and stop the recorder, manage timecode, and format the card without touching the talent. Quality-control audio also goes out over ZaxNet, so the mic can be checked on the spot with an ERX receiver.
NeverClip and ZHD
NeverClip gives 136 dB of dynamic range in both mono and stereo modes. ZHD modulation fits more channels into each megahertz of spectrum, with Mono, Stereo, XR, ZHD48, and ZHD96 modes for crowded RF environments.
Frequency Band
The US model covers 512 to 608 MHz, with output power of 25, 50, or 75 mW.
