Lectrosonics DCHT Tx
Designed for broadcast, film, and television production, the Lectrosonics DCHT is a wireless digital camera hop transmitter offering a reliable wireless connection between a bag- or cart-based audio system and cameras/recorders. This UHF transmitter tunes in coarse or fine increments from 470.1 to 607.95 MHz, and utilizes 256-bit encryption for secure signal transmission. With three selectable levels of RF power (10, 25, or 50mW) and a DSP-controlled input limiter, the DCHT delivers strong, clear, distortion-free audio. Also contributing to its solid sonic performance is its preamplifier, which accommodates lavalier/dynamic mics or line-level inputs, and provides up to 51 dB of gain in 1 dB steps. The TA6M input jack accepts two channels of analog mic-/line-level signal or a stereo AES3 digital feed via an array of cable adapters (available separately).
Tunes in coarse or fine steps across entire UHF frequency range from 470.1 to 607.95 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
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
Programmable switch can be configured as a mute switch, a power on/off switch, or be bypassed
Solid machined aluminum housing finished with a dark, ultra-hard, electroless nickel finish
Machined aluminum battery door is hinged to the housing, and latches securely to prevent accidental opening even if the DCHT is dropped
