1. INTRODUCTION
The PC80 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 (PC80E) 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 (PC80R), 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.
