Lectrosonics DCHT Wireless Digital Camera Hop Transmitter B1C1: 537.600 - 691.175 MHz
The DCHT portable digital stereo transmitter is designed for use in film and TV production as both a wireless audio link from a bag or cart system to cameras and as a portable IFB transmitter paired with the Duet digital wireless M2R receiver packs. The DCHT accepts two channels of mic or line level analog signals or an AES digital signal from a mixer and transmits to the receiver or receivers in a purely digital format. The digital architecture of the new DCHT is a third-generation design with specially developed, high-efficiency circuitry for extended operating time on two AA batteries.
This new version covers 537.600 - 691.175 MHz.
Lectrosonics DCHT transmitter B1/C1
26895 – Wire Belt Clip
40096 – 2x AA Batteries
AMJ-19 SMA-mount antennas
AMJ-22 SMA-mount antennas
Tunes in coarse or fine steps across entire UHF frequency range from 537.600 - 691.175 MHz
256-bit encryption (AES 256-CTR) for applications with high-level security
Selectable RF power at 10, 25, or 50mW
TA6M jack accepts two mic- or line-level analog signals, or a 2-channel AES3 digital feed via a variety of adapter cables (available separately)
Analog inputs can be linked for identical gain when used with a stereo source, or operate independently with individual settings
Input gain is adjustable over a 51 dB range in 1 dB steps to allow an exact match to the input signal level, maximizing the dynamic range and signal-to-noise ratio
Accommodates lavalier microphones, dynamic microphones, or line-level signals
Side-panel USB port for easy firmware updates
Compatible with Duet M2R receiver
Third-generation digital architecture with high-efficiency digital circuitry yields extended operating time on two AA batteries (available separately)
May be powered via an external DC power supply using the Lectrosonics LTBATELIM adapter (available separately), which replaces the battery door and provides a locking coaxial connector
