The DCHR portable digital stereo receiver is designed for use in film and TV production as both a wireless stereo audio link from a bag or cart system to cameras using a DCHT or M2T transmitter, or as a stand-alone miniature receiver for use with D Squared series mono transmitters. The DCHR provides two channels of mic or line level analog signals or an AES3 digital signal via a locking TA5M connector. The digital architecture of the DCHR is a 4th-generation design with specially developed, high-efficiency circuitry for extended operating time on two AA batteries.

The DCHR can tune across the available UHF TV band from 470 to 614 MHz (470-608 MHz when NA Locale is selected) in 100 kHz or 25 kHz steps, offering more than 6000 frequencies. The digital architecture allows for AES256-CTR encryption for applications where content security is a concern, and provides four different encryption key policies for a variety of applications. The DCHR can be camera mounted using the optional LRSHOE accessory.

Accessories

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 encrypted digital stereo transmitters, and the D2 Series mono digital transmitters, including the DBu, DHu, DBSM, DSSM, and DPR-A. 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. WARNING: Moisture, including talent’s sweat, will damage the receiver. Enclose the DCHR in our silicone cover (order part # DCHRCVR) or other protection to avoid damage.
