General Description

The APD4+ Amplified Antenna Splitter makes it possible to operate four UHF wire less
diversity microphone receivers on four separate frequencies using only two antennas.

It also features a high degree of output isolation; a necessity in multi-frequency
systems to prevent intermodulation. The APD4+ Splitter is compatible with Electro­Voice and Telex UHF diversity wireless receivers.

Features

The APD4+ is equipped with TNC type connectors. Low loss coaxial cables are also
supplied for splitter to receiver antenna jack connections. The APD4+ has an internal
power supply. Power out jacks and cables are provided to supply up to four receivers
thus eliminating excess power supply clutter.

Rack panel mounting “ears” al low the APD4+ to be mounted in a standard 19-inch
equipment rack. “Knock outs” in the ears al low front connection of antenna cables.

A new feature on the APD4+ is optional DC power on the antenna input jacks to
provide power for the UAA-500 low noise UHF antenna amplifier. The UAA-500 can
be used to make up for signal losses in long runs of coaxial cable.

An integrated switching power supply offers worldwide compatibility with the
appropriate IEC connecting cord.
