Connecting/disconnecting the ASA 214 to/from the
power supply system
To supply power to the ASA 214, the connected receivers and any antenna
amplifiers used, you will need the NT 1-1 power supply unit.
Only use the supplied NT 1-1 power supply unit. It is designed for your an-
tenna splitter and ensures safe operation.
To connect the ASA 214 antenna splitter to the power supply system:
▷Plug the hollow jack plug of the power supply unit into the DC IN socket
of the antenna splitter.
▷Pass the cable of the power supply unit through the cable grip.
▷Slide the supplied country adapter onto the power supply unit.
▷Plug the power supply unit into the wall socket.
To completely disconnect the ASA 214 antenna splitter from the power
supply system:
▷Unplug the power supply unit from the wall socket.
▷Unplug the hollow jack plug of the power supply unit from the DC IN
socket of the antenna splitter.

Connecting receivers to the ASA 214
You can connect and operate up to four stationary receivers to the
ASA 214.
Sennheiser receivers of the ew G4 and ew G3 series can also be supplied
with power from the ASA 214.
The following receivers are compatible:
evolution wireless G4:
•EM100G4
•EM300-500G4
evolution wireless G3:
•EM100G3
•EM300G3
• EM 500 G3
2000 series:
• EM 2000 (with its own power supply)
• EM 2050 (with its own power supply)
To connect the receivers to the ASA 214 antenna splitter:
▷Connect one of the receiver’s antenna inputs to one of the BNC sockets
A1 to A4 using one of the supplied BNC cables.
The compatible receivers listed above do not require their own power
supply. They are powered via the BNC sockets A1 to A4.
▷Connect the receiver’s other antenna input to one of the BNC sockets
B1 to B4 using one of the supplied BNC cables.

Connecting antennas
For more information about antennas and antenna accessories, see
“Antennas and accessories”.
In order to ensure optimal reception even in the case of poor recep-
tion conditions, we recommend using remote antennas.
Connecting remote antennas
▷Mount two antennas or a combination of an antenna and an antenna
amplifier to the BNC sockets ANT RF IN A and ANT RF IN B.
Connecting rod antennas
▷Mount the antennas to the BNC sockets ANT RF IN A and ANT RF IN B.
▷Align the antennas in a V-shape in order to ensure the best possible re-
ception.

Installing the ASA 214 in a rack
CAUTION
Rack mounting poses risks
When installing the device in a closed or multi-rack assembly, please con-
sider that, during operation, the ambient temperature, the mechanical
loading and the electrical potentials will be different from those of devices
which are not mounted into a rack.
▷Make sure that the ambient temperature within the rack does not ex-
ceed the permissible temperature limit specified in the specifications.
See “Specifications”.
▷Ensure sufficient ventilation; if necessary, provide additional ventila-
tion.
▷Make sure that the mechanical loading of the rack is even.
▷When connecting to the power supply system, observe the information
indicated on the type plate. Avoid circuit overloading. If necessary, pro-
vide overcurrent protection.
▷When rack mounting, please note that intrinsically harmless leakage
currents of the individual power supply units may accumulate, thereby
exceeding the allowable limit value. As a remedy, ground the rack via
an additional ground connection.

Mounting a single antenna splitter in a rack
To mount the antenna splitter in a rack, you will need the GA 3 rack mount-
ing kit (optional accessory).
To fasten the mounting angle of the GA 3 rack mounting kit:
▷Unscrew and remove the two recessed head screws (M4x8) on each
side of the antenna splitter.
▷Secure the mounting angles to the sides of the antenna splitter using
the previously removed recessed head screws.
►
▷Secure the blanking plate to one of the mounting angles using two re-
cessed head screws (M6x10).
►

▷Attach the antennas. You have the following options:
• Connect the supplied rod antennas on the rear side of the antenna
splitter. In this case, cover the antenna holes with the two covers (left
diagram).
• Attach the AM 2 antenna front mounting set (optional accessory) and
mount the rod antennas on the blanking plate (right diagram).
►
▷Slide the antenna splitter with the mounted blanking plate into the 19"
rack.
▷Secure the mounting angle and the blanking plate to the 19" rack.
▷Align the mounted antennas in a V-shape.

Mounting two antenna splitters side by side in a rack
To mount the antenna splitters using the GA 3 rack mounting kit (optional
accessory):
▷Place both antenna splitters upside down and side by side on an even
surface.
▷Secure the jointing plate to the transmitters using the six recessed
head screws (M3x6).
▷Secure the mounting angle.

Switching the ASA 214 on and off
To switch on the antenna splitter:
▷Short-press the STANDBY button.
The antenna splitter switches on and the power LED turns green.
The RF signals of the connected antennas are distributed to all con-
nected receivers.
►
To switch the antenna splitter to standby mode:
▷Press the STANDBY button for approx. 2 seconds.
The LED turns off. The connected antenna amplifiers are switched off.
Connected receivers are switched off if they draw their supply voltage
from the BNC sockets A1 to A4 (see “Connecting receivers to the
ASA 214”).
To fully switch off the antenna splitter:
▷Disconnect the antenna splitter from the power supply system by un-
plugging the power supply unit from the wall socket.
The LED turns off.
