Wireless recording is expensive. But TASCAM's DR-10X plug-on recorder connects to any dynamic or battery-powered condenser microphone via XLR to record for easy post-production synchronization.
The DR-10X is about the size of a plug-on wireless transmitter. It's powered by a AAA battery and records to MicroSD. You can also connect headphones via the 3.5 mm jack for real-time monitoring or playback.
More than just a recorder, TASCAM packed in some handy audio processing features: adjustable mic gain, low-cut filter, limiter, and automatic record level. The DR-10X also offers dual-record mode for simultaneous recording the same audio at 6 dB lower for extra headroom.
Tascam also put an infrared transmitter and receiver into the DR-10X to make for easy setup with multiple units.
