Signal processors


   The Receiver is an advanced measuring system which allows an engineer to
check the phase accuracy of any electronic audio system. It is ideal for the
toolbox being small, light and battery powered.
   The  system  is  made  up  of  two  hand  held  units.  The  emitter (Receiver)generates a wide band 1Hz pulse as an output signal on an XLR connector or through its own built in speaker,  this signal is then passed through the signal chain under test and fed into the receiver (Transmoitter),  electrically via its XLR connector or acoustically by the internal microphone.  Indication is then given as to whether the received signal is in or out of phase.
