ZAXCOM TRX745 Trasmettitore Plug-on, banda 512-698 MHz

Zaxcom TRX 745: Digital Recording Plug-on transmitter covering Blocks 20-26 (512 - 698 MHz).
The TRX745 is a wide-band plug-on style digital wireless microphone transmitter with interchangeable cones to support all professional microphone varieties, mono analog, stereo analog, AES and AES42, making it an ideal choice for wireless transmission directly from boom poles or handheld microphones.

Il TRX 745 è completo di uno dei 4 possibili coni da indicare al momento dell'acquisto:
Cone choices (appended to model name):
mono analog, 3-pin XLR (-A)
stereo analog, 5-pin XLR (-S)
AES (not powered), 3-pin XLR (-AES)
AES42 (powered), 3-pin XLR (-42)

The TRX745 features the Zaxcom High Density (ZHD) Modulation. Range will always vary depending on your environment, but you've got choices to optimize transmission for peak performance. Zaxcom High Density modulation (ZHD) increases the number of available channels from 4 to 9 for every 1 MHz of spectrum space, perfect for reflective environments like busy city streets. XR gives you the maximum distance in less dense / more controlled spaces. The ZHD transmitters are capable of running all existing mono Zaxcom modulations maintaining compatibility with all currently produced Zaxcom receivers.
