a fault in a large audio system can be a real pain, particularly if
itís to do with phase or polarity. Such problems are difficult to
isolate without spending precious time re-plugging and testing.
Often imitated, but never bettered, the LA Audio Phase Checking system's wide
band pulse can detect polarity inversions both acoustically and
electronically irrespective of distance or time delay, making it easy
to isolate cable, speaker or processor faults quickly.
The PC90 is the latest incarnation of this advanced system, capable of
measuring phase accuracy in any audio system.The separate emitter and
receiver can be placed anywhere throughout an audio system, using
either its internal speaker and microphone, or a balanced XLR
As soon as the emitter eeks out its little pulse,
the receiver will indicate whether the signal is received in or out of
phase.Barely seconds later, when your problem has been solved, the two
units couple together, ready to be thrown into your pocket or toolbox.
So, if you need a time saving, hassle free, rock solid and cool looking little audio friend, look no further than PC90.
