DCHR

Description

Tunes across 144 MHz from 470-614 MHz (covers A1 and B1 ranges)
Compatible with DBSM, DBu, DHu, DPR, DCHT and M2T Transmitters
Selectable AES3 or analog mic/line level outputs
256-bit encryption – AES 256-CTR
USB port for firmware updates
Two AA battery power
Solid machined aluminum housing
Optional powering from external DC with LTBATELIM
Extremely fast RF scanning and setup via IR

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.

Firmware

Below is a link to the current firmware update file for the Digital Camera Hop Series products – DCHR receiver and DCHT transmitter. This is a zip file, after downloading extract it into a temporary folder. Use the Wireless Designer™ program to update firmware, instructions are found here.

Note: This is a link to the Wireless Designer firmware update file, which bundles the latest firmware for multiple products. Wireless Designer will automatically choose the right firmware images from the file. To update firmware in the DCHR receiver, Wireless Designer version 2.0.27 (Windows) or 2.0.22 (macOS) or higher is required.

DCHT versions 1.10 and higher work with M2R receivers using either 2.x or 3.x firmware, while DCHT versions 1.05 and lower work only with M2R receivers using 2.x firmware. All DCHT firmware versions work with the DCHR receiver.

WD Firmware Update v23Jul2024

DCHR v1.22 (SUPER)/v3.02 (FPGA H/W v5)/v2.01 (FPGA H/W v4)/v1.12 (FPGA H/W v0,1,3)

When the “Tx Batt Display” is set to “timer”, the maximum elapsed time is now 99 hours and 59 minutes, and the colon character separating hours and minutes flashes.

WD Firmware Update v30Apr2024

DCHR v1.21 (SUPER)/v3.02 (FPGA H/W v5)/v2.01 (FPGA H/W v4)/v1.12 (FPGA H/W v0,1,3)

D2 compatibility mode updated to improve reception of weak or distorted signals.
“Sync/Encryption” renamed to “IR & Keys” and it now includes a “Group Sync” menu item.
The default compatibility setting is now DUET mode.
Added support for the B1C1 frequency band.
Now, when pressing the power button to power up the receiver, it doesn’t power down again if the button is held too long.
Automatic low voltage shutdown logic now requires that the low voltage condition persist for 5 seconds before the device shuts down.
Fixed bug in the Scan page where selected frequencies at the edge of the scan view were not displayed when the scan was zoomed.

WD Firmware Update v19Jun2023

DCHR v1.17 (SUPER)/v3.00 (FPGA H/W v5)/v2.00 (FPGA H/W v4)v1.11 (FPGA H/W v0,1,3)

Fixes a vulnerability to certain types of flickering lights which confused the IR port and caused the microprocessor to hang.

WD Firmware Update v05Sep2022

DCHR v1.15 (SUPER)/v3.00 (FPGA H/W v5)/v2.00 (FPGA H/W v4)/v1.11 (FPGA H/W v0,1,3)

Compatibility release for audio boards with hardware version DCHR-5. No new features.

WD Firmware Update v13Jul2022

DCHR v1.13 (SUPER)/v2.00 (FPGA H/W v4)/v1.11 (FPGA H/W v0,1,3)

Compatibility release for audio boards with hardware version DCHR-4. No new features.

WD Firmware Update v28Oct2021

DCHR v1.12 (SUPER)/v1.11 (FPGA H/W v0,1,3)

Fixed reversed headphone output audio polarity.

WD Firmware Update v06Apr2021

DCHR v1.08 (SUPER)/v1.10 (FPGA H/W v0,1)

Add HDM compatability mode.
Disable power button when settings are locked.
Don’t highlight the selected item in the frequency list when the group selection control has the focus.
Rename “Freq Group Edit” item in RF setup menu to “Tuning Groups”.

WD Firmware Update v13Jan2021

DCHR v1.07 (SUPER)/v1.07 (FPGA H/W v0,1)

Implement Frequency Group sync operations “Send Group” and “Get Group”, adding them to the “Sync/Encryption” menu.
Separate mix mode settings are now stored for each compatibility mode. When the compatibility mode is changed, the associated mix mode is recalled automatically.
When adding a frequency to a group in the Freq Group Edit page, the entry control now defaults to the last frequency added.
Default compatibility mode changed to DCHX.
The DCHT now conforms to Lectrosonics’s new 2-way IR Universal Sync Protocol, meaning that now or soon, it will be able to perform the four basic IR sync operations (“Send Freq”, “Send All”, “Get Freq” and “Get All”) with any other 2-way IR equipped Lectrosonics wireless product.
Fix bug causing “tone in headphones” function to fail if test tone is toggled on/off in the “Audio Level” page before enabling the function in the “Test Tone in HP” page.
In “Locale” page, allow non-destructive browsing of locale options such that the frequency of operation remains unchanged on exit from the page if the locale setting wasn’t changed.
