Lectrosonics Dcht Wireless Digital Camera Hop Transmitter (470 To 607 Mhz)
- Product Code: ga191924
-
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 to 607 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). The DCHT boasts up to five hours of battery life via two AA batteries (available separately) safely held in place by a latching aluminum battery door. External DC powering is possible through the LTBATELIM adapter (available separately). The DCHT's rugged housing is constructed from solid machined aluminum coated in an ultra-hard electroless nickel finish. A detachable wire belt clip allows the DCHT to be easily affixed for versatile positioning.For Broadcast, Film, and TV Production 470 to 607 MHz UHF Frequency Band Secure 256-Bit Encryption 10, 25, or 50mW Selectable RF Power Up to 51 dB of Gain in 1 dB Steps DSP-Controlled Input Limiter TA6M Jack for AES3 or Analog Mic/Line In Powered via AA Batteries Battery Life up to 5 Hours Aluminum Housing with Belt Clip

Related Questions and Answers
Q: 1. Can this devise used for video mode? while shooting video?
A: Yes it can. It works very well for both photos and video.
Q: 2. How does this product provide extended battery life?
A: This grip holds 2 batteries, instead of the one in just the camera.
Q: 3. Is this the wireless transmitter for use with the Nikon Z cameras, too? (they're not listed on the specs)
A: Yes For Z 7, Z 6, D850, and D500
Q: 4. Does this work with C500 mark II?
A: According to Canon's website, it is not listed as an accessory for the C500 mk2.
Q: 5. What is the speed of the ethernet cable 100 or 1000? There is only wifi speed.
A: This supports up to 1000BASE-T.
Q: 6. How fast are file transfer for jpg and raw?
A: The transfer Speed-Up to 867 Mb/s with 802.11ac 2x2 MIMO Wi-Fi.
Q: 7. The description reads "It holds two LP-E6NH/LP-E6N/LP-E6 battery packs for effectively double the runtime." but on the Canon website it states "*Each of the batteries works independently, supplying power to the camera and Wireless File Transmitter separately." Does this mean that at all times the grip will only draw power from one battery during normal usage, or does it only split the power when it's actively using the wireless capability?
A: If only one battery is inserted into the chamber for the camera to the right of the magazine, the transmitter will not function. Two battery would be needed in order to run the camera and the transmitter at the same time, with each battery controlling individually.
Q: 8. If you shoot RAW+JPG, can you transfer just the .jpgs (for speed) while having RAW images on the card?
A: When using the Canon WFT-R10A Wireless File Transmitter for EOS R5 C & R5 Mirrorless Camera to transfer files, you can choose the type and size of file to transfer--JPEG Large, JPEG Small, etc.
Q: 9. is this the same physical size as the BG R 10, as I have an L Bracket from RRS that fits with the current battery grip?
A: According to Canon USA, they state the Canon WFT-R10A shares the same physical dimensions of the Canon BG-R10 battery grip. While they have not tested the Canon WFT-R10A on the Really Right Stuff EOS R5 and R6 with BG-R10 Vertical Battery Grip L-Plate, tit is possible the two items may be compatible with one another.
Q: 10. What is the difference between A1, A, and G? What should I use if I'm filming mainly in Los Angeles?
A: Sennheiser breaks up the legal frequency range for wireless microphones of 470-608 MHz into three blocks. I would recommend the A1 block for Los Angeles, which is 540-516 MHZ. But all of the three groups have 1680 frequencies, and the ability to auto scan to find a clean channel.
