Introduction
Audio Wireless Diversity Antenna Distribution Module
(DADM226) consists of 3 sections:
A. Antenna Distribution Section
B. Mast Head Amplifier (MHA) Powering Section
C. DC power distribution Section
A. Antenna Distribution Section
This section includes 2 x 2 BNC antenna Inputs and
distributes the received signal to 2 x 6 SMA RF Output.
The RF section has a custom designed Band-Pass Filter to
reject the unwanted signals outside the pass band.
B. Mast Head Amplifier (MHA) Powering Section
Switchable T-bias may be used to power in-line antenna
amplifiers or remote antenna booster amplifiers (active
antennas) to compensate long antenna extension cables.
C. DC Power Distribution Section
This section includes one dc input connector (Hirose)
located at the front panel(green LED ON) and 3 x DC
Hirose outputs at the RHS panel (individually switchable)
to power Radio Receivers or any auxiliary sound
equipment.

DADM226 Quick Setup Guide
Step-by-Step Setup:
1. Connect the Receivers with a short RF link
cable to "Antenna A Outputs" and
"Antenna B Outputs" (SMA). Care should
be taken so that Antenna "A" and "B"
outputs are connected correctly to the
corresponding antenna "A" and "B"
inputs on the Receivers for proper
diversity operation.
2. Connect the antennas with a short
antenna extension cable to the two BNC
Antenna Input connectors.
3. Turn ON/OFF switch to ON – the system
is ready (GREEN LED ON).
4. Use the UP arrow to navigate through the
menu
5. "AW-RX POWER" select ON to power
"Audio Wireless or Micron receivers"
through antenna inputs, for all other
receivers this function MUST be OFF.
6. "MHA POWER" activated ON to power
active antenna amplifiers (RED LED ON)
7. HIROSE DC POWER activated ON for dc-
distribution.

WELCOME PAGE The GREEN LED and the “Welcome Page” will be displayed when the unit turned ON. (the “Welcome Page” is displayed and the “MHA PWR” RED LED’s temporarily flashes, the OLED display is “ON” for 3 seconds and it goes into sleep mode, if the master switch was set at “OFF” position) when the dc power cable plugged in. 2. INPUT DC VOLTS System dc input volt meter 3. AW-RX POWERING Audio Wireless and Micron receiver powering options through the antenna inputs. Warning Other brand receivers, “AW-RX Powering” 1-6 should be OFF 4. MHA POWERING MHA power may be activated if an “In-Line Antenna Amplifier” and/or an “Active Antenna Booster Amplifier” is used, Antenna “A” and/or “B” can be activated independently, RED LED ON.
