Lectrosonics DCHR Data Sheet
DCHR
Digital Camera Hop Receiver
TECHNICAL DATA
• Tunes across a wide UHF frequency range
• 256-bit encryption - AES 256-CTR
• AES3 and dual mic/line level analog outputs
• Headphone monitor output
•
USB port for firmware updates
• Compatible with DCHT , M2T, M2T-X, and
D2 Series transmitters (DBu, DHu, DPR)
• 2-way IR (infrared) port for fast setup
• 2 AA battery power
• Solid machined aluminum housing
The DCHR Digital Receiver is engineered to work
alongside the DCHT transmitter to form the Digital
Camera Hop system. The receiver is also compatible
with the M2T unencrypted and M2T-X encrypted digital
stereo transmitters, and the D2 Series mono digital
transmitters, including the DBu, DHu, and DPR. Designed to be camera mountable and battery powered,
the receiver is ideal for location sound and televised
sports, along with many other applications. The DCHR
employs advanced antenna diversity switching during
digital packet headers for seamless audio. The receiver
tunes across a wide UHF frequency range.
The headphone monitor output is fed from a high-quality stereo amplifier with power available to drive even
inefficient headphones or earphones to sufficient levels
for noisy environments. An intuitive interface and high
resolution LCD on the unit provide users with a quick
read on the status of the system.
The DCHR also employs 2-way IR sync, so settings
from the receiver can be sent to a transmitter. This
way, frequency planning and coordination can be done
quickly and confidently with on-site RF information.
DCHR Summary
The DCHR operates in the UHF frequencies of
470.100 to - 607.950 MHz in a single range for maxi-

mum flexibility. The Locale setting is used to restrict
m
the tuning range for North American users to an upper
limit of 607.375 MHz.
The receiver employs AES 256-bit, CTR mode encryption for robust security, and four key management
policy choices for different applications.
Housings and panels are made of machined aluminum
with ebENi finishes (black electroless nickel plating)
with laser etched marking for durability, yet they are
lightweight and sleek in order to occupy minimal space
on a camera. The DCHR features a user-friendly interface with a high-resolution, backlit LCD and membrane
switches for ease of setup and system monitoring.
The DCHR runs for 8 hours on two lithium AA batteries.
