The DX true diversity receiver

Compact. Powerful. Totally reliable.

The power of true diversity

The DX is the world’s smallest battery powered true diversity receiver which makes it ideal for documentary or ENG work. It is equipped with two antennae, each connected to its own receiver inside the unit. The DX automatically switches between the two receivers ensuring the strongest signal is always captured. That means you will experience no break up of sound (drop-outs) even in built-up areas where signals bouncing off walls and metal objects (reflections) can cause cancellations.

What is 'true diversity'?

Some manufacturers offer ‘diversity receivers’ with two antennae connected to only a single receiver. Signal switching
takes place between the antennae (at rf level) which means there is often an audible ‘click’ on the recorded sound as
the signal being delivered to the receiver is momentarily interrupted during switching. With the true diversity DX,
that problem doesn’t happen since switching takes place between the two receivers at the audio frequency level with
no interruption of signal.

External powering

The DX receiver can be externally powered from 6 – 18V DC allowing it to be camera mounted or placed in the mixer bag and powered from a single external source.

Easy Setup

Easy setup menus

This unit is set up using a series of menus which are viewed in the OLED display. You are guided through the set up by a series of easy-to-read symbols and all parameters are selected using three buttons on the unit’s front panel. It’s so straightforward you won’t need any further written instructions from us.


OLED menu driven displays

This unit has an organic light emitting diode (OLED) display which is extremely clear yet consumes very little power. The screen shows all the important information you need to monitor the system when in use and also displays the En2’s unique easy set-up menu.


Frequency scan function

In an increasingly crowded environment, you need to be able to select usable frequencies on location quickly. So, all receivers in the En2 range have a built-in scan facility which allows you to scan for a free channel or scan for the transmitter. In addition, on this unit, selecting ‘tune’ mode brings up a spectrum analyser type display which allows you to see the RF in the local environment.
