The ZFR400 is a ultra small bodypack timecode stamped audio recorder with features you can't get anywhere but Zaxcom! It can record professional quality audio as a stand-alone device without the need of additional transmitters or receivers. Audio is recorded internally onto a microSD card using the highly reliable lossless MARF (Mobile Audio Recording Format) that eliminates file corruption common to recordings due to dead battery or early card removal. A built-in timecode reader and generator will synchronise timecode, making recordings in post production more effective.

The ZFR400 is housed in a high strength, impact resistant nylon polymer casing with rounded edges, machined metal and rubber gaskets. It measures only 56 x 41 x 14mm and weighs 62g. The battery provides up to 10 hours of run time and its door is magnetically latched and sealed to protect it against the harshest of production environments. The combination of the nylon composite case and its power efficiency makes heat transfer practically nonexistent, allowing the ZFR400 to run cool.

The ZFR400 also provides a timecode output through the 3-pin Lemo connector that can be used to jam any SMPTE timecode compatible device. NeverClip is also included to give an unprecedented 128 dB of dynamic range without clipping audio. While using NeverClip, two separate analog to digital converters work in conjunction to provide a natural distortion free dynamic range.

The ZFR400 works with ZaxNet, Zaxcom's 2.4 GHz RF network that distributes remote control commands, timecode and IFB audio. With ZaxNet, one can remotely control transmitter settings such as gain and transport controls. The ZFR400 also sends a Quality Control audio signal over ZaxNet so when micing someone you can use an ERX audio receiver to listen to the mic right on the spot.
