EV APD-4+
UHF ANTENNA / POWER DISTRIBUTION SYSTEM
The APD4+ is a UHF antenna/power distribution system for use with RE-2 and REV receivers, providing power and RF signals for 4 units.
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.
- Provides diversity antenna distribution to four single receivers
- Provides power distribution for four RE-2 receivers
- Universal power supply with IEC power cord
- Phantom power on antenna inputs for UAA-500 amplifier
- Can be cascaded to provide antennas for up to 16 receivers (requires 5 APD4+)
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.
