Deity Connect 2.4Ghz Wireless System
Connect With The World Differently
Releasing Early 2019
Finally A Professional Grade 2.4Ghz Wireless System
Taking a cue from industry professional wireless companies we wanted Deity Connect to have the same reliable signal and audio quality. For this we started off with a list of requirements we knew we had to include:
-
Dual Channel Receiver with Top-Down Ergonomics
-
24bit/48Khz Uncompressed Audio
-
SMA Antenna Ports
-
USB-C QuickCharge
-
OLED Daylight Display Screens
-
Input Gain Control at the TX
-
Adjustable Output Levels
-
Dual Outputs
-
Transmitter with a Low Cut, Limiter, and High Freq Boost
-
>10Hr Battery Life; Charges in 1Hr
The BP-TX
Built Like UHF, Features Only 2.4Ghz Can Deliver
The BP-TX is made out of CNC aluminum to give it a tough, durable build quality. The top of the unit features a SMA antenna connector, a 1/4″ 20 mounting point for the belt clip, and a locking 3.5mm standard microphone input. With 2 multi-color LED alert lights you will be able to tell the status at just a glance. The daylight bright OLED display offers a fast refresh rate so VU meters bounce in real time. The high resolution of the OLED display allows for the statuses of all the major features to be displayed on the home screen.
The RF power output is 100mw / 50mw / 25mw / 10mw/ or AUTO. When you set the BP-TX to AUTO RF Power the DUO-RX will transmit a pulse to the BP-TX (if the signal drops below the threshold), telling the BP-TX to increase its RF power output to help prevent a loss of signal. Using AUTO RF Power will also increase your battery life because you will never use more power than the system actually needs.
All settings on the BP-TX can be over written in the menu of the DUO-RX. Now you no longer have to walk over to an actor to change a simple setting. Simple pull up which transmitter you need to adjust in the menu of the DUO-RX, make the change, and instantly the BP-TX updates to the new setting.
The DUO-RX
From the start we wanted the Deity Connect system to work with the ergonomics of a sound bag. The DUO-RX was designed so that the screen, buttons, and antenna all face up in a sound bag so the operator does not need to remove it. And with the USB-C power and audio outputs on the bottom, the cable management can be maximized inside the audio bag. These two ergonomic principals also allow for the screen to face camera operators when mounting it onto a camera, instead of facing the ceiling like other brands.
QUAD Antenna Design
We added dual SMA elbow antennas so no matter how you mount the DUO-RX your external antenna can always be mounted vertically. But we took it a step further by adding two dipole internal horizontal antennas to capture signals on the horizontal plane. This quad design gives us a dual true diversity setup across two receiver modules. This is the same method used in commercial grade WiFi and high-end drones. And because we offer users removable antennas, you can upgrade the antenna array yourself if you want to add a clover antenna, directional antenna, or even connect to a 2.4Ghz antenna splitter.
But what About WiFi? Isn’t 2.4Ghz Full of Interference?
The Deity Connect ecosystem uses a proprietary protocol that was engineered with several mechanisms to ensure a strong audio link while at the same time co-existing peacefully with other 2.4Ghz devices using the same frequency band.
The first mechanism is adaptive frequency hopping, automatically hopping before RF interference even happens. At any given time, the BP-TX is hopping between 9 different frequencies. The Deity Connect system is more than just a transmitter and a receiver link – it’s a bi-directional transceiver system that is always scanning and mapping out the whole 2.4Ghz frequency band, coordinating and planning the next 70 frequency hops.
The second mechanism used to prevent RF Interruption is called Listen-Before-Talk. If RF Interruption is detected or even thought to have taken place, the system will add the audio and data in the next two frequency hops after the ‘bad’ hop. The DUO-RX will then add that extra audio and data back into the stream as if the ‘bad’ never existed, giving you an uninterrupted stream of audio from your transmitter. Deity Connect uses the natural latency in the system as a buffer, allowing it to absorb ‘bad’ hops much like the CD Player Skip Protection feature but in a millisecond flash.
