The AC 3 active transmitter combiner
The AC 3 active transmitter
combiner
With the AC 3 4-to-1 active transmitter combiner, the signals of
up to four SR 300 IEM G3 type transmitters can be combined
onto a single antenna.
The integral active RF amplifiers ensure that the input signals
are combined onto the common antenna output with no distri-
bution attenuation.
The AC 3 incorporates DC distribution to enable simultaneous
powering of up to four transmitters via its BNC sockets. A single
NT 3-1 table top power supply (see "Accessories" on page 15)
is required to power the AC 3 and the connected transmitters.
Using the GA 3 rack adapter (see "Accessories" on page 15),
one AC 3 and one stationary SR 300 IEM G3 type transmitter
can be mounted into a 19" rack.
Alternatively, you can stack the AC 3. For stacking the AC 3,
mount the optional stacking elements (see "Accessories" on
page 15).
The AC 3 is suitable for the following areas of application:
· Multi-channel monitoring systems for stage use
· Multi-channel systems suitable for any application where
talk-back signals are to be transmitted (e.g. studio)
Delivery includes
1 AC 3 active transmitter combiner
1 set of device feet
4BNC cables
1 instruction manual
You additionally require the NT 3-1 table top power supply with
a suitable mains connector (see "Accessories" on page 15).
