Proception proMHD14R 4 Output Dual Mode Amp

Dual-mode operation can operate as an aerial amplifier, or as a return-path amplifier with Sky remote control facilities.
Flexible powering options: 5 - 12 V in aerial-amplifier mode 9 V from Sky receiver in return-path mode.
Excellent noise figure and output capability.
Input filtered below 470 MHz to reduce risk of interference problems from CB, private mobile radio TETRA etc.
Suitable for both digital and analogue applications fully DTT-compatible.

Application guide.
Aerial-amplifier mode: in this mode the proMHD14R functions as a straightforward 4 way UHF masthead amplifier. The input will usually come directly from the UHF antenna. Power (5 - 12 V DC) can be supplied via any of the four outputs, providing flexibility in the location of the power unit. In this mode no power is passed to the other outputs and the return-path amplifier stage is disabled.
Return-path mode: this mode is automatically enabled when the amplifier is powered via its input. Usually the input will be fed directly from the second RF output (RF OUT-2) of a Sky Digibox or Skyplus receiver, which should have its 9 V second outlet powering enabled (see over). In return-path mode power is present at all outputs for powering remote infrared receiver eyes. Infrared receiver power is individually short-circuit protected, so that a DC short at any output will not affect operation of remote control via the other outputs.
