Zaxcom in Booth C1758 announced its latest line of digital recording wireless transmitters with a brand new type of modulation, Zaxcom High Density (ZHD). ZHD modulation allows for up to 10 channels of wireless to be operated in one MHz of frequency spectrum space.
Like other Zaxcom Digital Wireless transmitters, the new ZHD models, the TRXLT3, TRXLA3 and TRX743 are 100-percent digital, have built-in backup recording with timecode and NeverClip for superior dynamic range. They are also fully encrypted. When using ZHD modulation the wireless signal is 50kHz wide and can be spaced as close as 100kHz apart, so a single North American television channel of 6 MHz can contain up to 60 channels of Zaxcom high density wireless. The narrow signal gives the transmitters outstanding operating distance. This, along with the 100kHz spacing, promises to effectively solve the spectrum availability problems for UHF wireless microphones.
The new ZHD transmitters will run all existing mono Zaxcom transmitter modulations maintaining compatibility with all currently produced Zaxcom receivers.
