The new ULXD4D dual channel digital receiver packs two channels of wireless into one rack space, with individual gain controls, LED meters, and XLR outputs for each channel. Like the single-channel, half-rack ULXD4 digital receiver, the new dual and quad receivers feature fully digital audio processing and RF transmission as well as AES 256-bit encryption.
High Density Mode (designed for high channel count applications requiring a working range up to 30 metres), allows operating up to 560 (five hundred & sixty) channels in 72 MHz, respectively 63 channels in an 8 MHz TV channel. High Density mode optimizes the system’s output power and digital RF filtering to reduce its spectral footprint from 350 kHz to 125 kHz, with no loss of sound quality. This allows ULX-D systems be tuned to frequencies that are much closer together without interfering with each other. Even in Standard mode, up to 22 ULX-D systems can operate in 8 MHz.
