Digital Camera Hop Receiver

DCHR Digital Stereo/Mono Receiver
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 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 DCHR has a single audio output jack that can be configured as 2 independent balanced, adjustable mic/ line level outputs or as a single 2 channel AES3 digital output.
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.
Smart Tuning (SmartTuneTM)
A major problem facing wireless users is finding clear operating frequencies, especially in RF saturated environments. SmartTuneTM overcomes this problem by automatically scanning all the frequencies available in the unit, and tuning to the frequency with the lowest RF interference, significantly reducing setup time.
Encryption
The DCHR provides AES 256-bit, CTR mode encryption. When transmitting audio, there are situations where privacy is essential, such as during professional sporting events. High entropy encryption keys are first created by the DCHR. The key is then synced with an encryption capable transmitter/receiver via the IR port. The audio will be encrypted and can only be decoded and heard if both the transmitter and the DCHR have the matching key. Four key management policies are available.

RF Front-End with Tracking Filter
A wide tuning range is helpful in finding clear frequencies for operation, however, it also allows a greater range of interfering signals to enter the receiver. The UHF frequency band, where almost all wireless microphone systems operate, is heavily populated by high power TV transmissions. The TV signals are immensely more powerful than a wireless microphone or portable transmitter signal and will enter the receiver even when they are on significantly different frequencies than the wireless system. This powerful energy appears as noise to the receiver, and has the same effect as the noise that occurs with extreme operating range of the wireless system (noise bursts and dropouts). To alleviate this interference, high-quality front-end filters are needed in the receiver to suppress RF energy below and above the operating frequency.
The DCHR receiver employs a selective frequency, tracking filter in the front- end section (the first circuit stage following the antenna). As the operating frequency is changed, the filters re-tune into six different “zones” depending on the selected carrier frequency.

In the front-end circuitry, a tuned filter is followed by an amplifier and then another filter to provide the selectivity needed to suppress interference, yet provide a wide tuning range and retain the sensitivity needed for extended operating range.

Battery Status LED
When the battery status LED on the keypad glows green the batteries are good. The color changes to red at a midpoint during the runtime. When the LED begins to blink red, only a few minutes remain.
The exact point at which the LED turns red will vary with battery brand and condition, temperature and power consumption. The LED is intended to simply catch your attention, not to be an exact indicator of remaining time. The proper battery type setting in the menu will increase accuracy.
A weak battery will sometimes cause the LED to glow green immediately after the transmitter is turned on, but it will soon discharge to the point where the LED will turn red or the unit will turn off completely.
RF Link LED
When a valid RF signal from a transmitter is received, this LED will light up blue.

Menu Item Descriptions
RF Setup Menu
SmartTune
SmartTuneTM automates the discovery of a clear operating frequency. It does this by scanning all the available operating frequencies within the system’s frequency range (in 100 kHz increments) and then selecting the frequency with the least amount of RF interference. When SmartTuneTM is complete, it presents the IR Sync function for transferring the new setting to the transmitter. Pressing “Back” returns to the Main Window displaying the selected operating frequency.
RF Frequency
Allows manual selection of the operating frequency in MHz and kHz, tunable in 25 kHz steps.
You may also select a Frequency Group, which will limit the available frequency choices to those contained in the selected group (see Freq. Group Edit, below). Select Frequency Group NONE for normal tuning.
Frequency Scan
Use the scan function to identify a usable frequency. Allow the scan to continue until the entire band has been scanned.
Once a full cycle has been completed, press MENU/SELECT again to pause the scan.
Use the UP and DOWN arrows to roughly tune the receiver by moving the cursor to an open spot. Press MENU/SELECT to zoom in for fine tuning. Zoom will show the selected frequency at the edges of the scan range.
When a usable frequency has been selected, press the BACK button for the option to keep your newly selected frequency or to revert to where it was set before the scan.
Clear Scan
Erases scan results from memory.
Freq. Group Edit
User-defined Frequency Groups are edited here. Groups u, v, w and x may contain up to 32 user-selected frequencies. Use the UP and DOWN arrow buttons to select one of the four groups. Press the MENU/SELECT button to move the cursor to the frequency list for the group. Now, pressing the UP and DOWN arrow buttons moves the cursor in the list. To delete a selected frequency from the list, press MENU/SELECT + DOWN. To add a frequency to the list, press MENU/SELECT + UP. This opens the Frequency Selection screen. Use the UP and DOWN arrow buttons to select the desired frequency (in MHz and kHz). Press MENU/SELECT to advance from MHz to kHz. Press MENU/SELECT again to add the frequency. This opens a confirmation screen, where
10

you can choose to add the frequency to the Group or cancel the operation.
In addition to the group NONE, this screen also allows selection of one of four user-defined pre-selected frequency groups (Groups u through x):
· Each press of the UP or DOWN button will step to the next stored frequency in the group.
Audio Setup Menu
Audio Level
Set audio output level with the level control. The TONE option is used to generate a 1 kHz test tone at the audio output.
SmartNR
For audio sources containing an undesirable amount of hiss (some lav mics, for instance), SmartNR can be used to reduce this noise without affecting the quality of the audio. The default setting for the DCHR is “Off”, while “Normal” provides some noise reduction without affecting high frequency response, and “Full” is a more aggressive setting with minimal impact on the high frequency response.
Mixer
If working with a two channel transmitter, such as a DCHT or M2T, this function allows you to hear a stereo mix, a mono mix from either audio Channel 1 (left), Channel 2 (right) or a mono mixture of both Channel 1 and 2. The chosen mix applies to all outputs (analog, digital and headphone). The following modes, which are Compatibility Mode dependent, are available:
· Stereo: Channel 1 (left) to output 1 and channel 2 (right) into output 2
· Mono Channel 1: channel 1 signal into both outputs 1 and 2
· Mono Channel 2: channel 2 signal into both outputs 1 and 2
· Mono Channel 1+2: channels 1 and 2 mixed as mono into both outputs 1 and 2
Note: D2 and HDM modes have Mono Channel 1+2 as the only mixer option.
Compat Modes
Multiple compatibility modes are available to match various transmitter types.
The following modes are available:
· D2: Encrypted digital wireless channel
· DUET: Standard (unencrypted) Duet channel
· DCHX: Encrypted digital camera hop channel, also compatible with M2T-X encrypted Duet channel
· HDM: High density mode

Key Type
Encryption Keys
The DCHR generates high entropy encryption keys to sync with encryption- capable transmitters and receivers. The user must select a key type and create a key in the DCHR, and then sync the key with a transmitter or another receiver (only in shared key mode).
Encryption Key Management
The DCHR has four options for encryption keys: · Volatile: This one-time only key is the highest level of encryption security. The Volatile Key exists only as long as the power in both the DCHR and the encryption capable transmitter remains on during a single session. If an encryption capable transmtter is powered off, but the DCHR has remained turned on, the Volatile Key must be sent to the transmitter again. If the power is turned off
Rio Rancho, NM

on the DCHR, the entire session concludes and a new Volatile Key must be generated by the DCHR and sent to the transmitter via the IR port. · Standard: Standard Keys are unique to the DCHR. The DCHR generates the Standard Key. The DCHR is the sole source of the Standard Key, and because of this, the DCHR may not receive (get) any Standard Keys. · Shared: There are an unlimited number of shared keys available. Once generated by the DCHR and transferred to an encryption capable transmitter/receiver, the encryption key is available to be shared (synced) with other encryption capable transmitters/receivers via the IR port. When the DCHR is set to this key type, a menu item named SEND KEY is available to transfer the key to another device. · Universal: This is the most convenient encryption option available. All encryption-capable Lectrosonics transmitters and receivers contain the Universal Key. The key does not have to be generated by the DCHR. Simply set a Lectrosonics encryption capable transmitter and the DCHR to Universal, and the encryption is in place. This allows for convenient encryption amongst multiple transmitters and receivers, but not as secure as creating a unique key.
NOTE: When the DCHR is set to Universal Encryption Key, Wipe Key and Share Key will not appear in the menu.
Make Key
The DCHR generates high entropy encryption keys to sync with encryption- capable transmitters and receivers. The user must select a key type and create a key in the DCHR, and then sync the key with a transmitter or receiver. Not available in Universal key mode.
